Blockchain Developer Job Description Template 2026

Last updated: September 25, 2026

By Jennifer Burdick, Recruiting Manager, KORE1

A blockchain developer job description should name the chain and contract language, the test toolchain, how much value the code will control, who holds signing keys, how the code exercise is delivered, and the pay, tokens included. Base pay starts around $125,000 for mid-level smart contract work this year and reaches $230,000 for a senior one, before any tokens. A posting that skips the chain and the keys reads, to a careful engineer, a lot like a scam.

Crypto reqs have come across my desk at KORE1 through two bull markets and the long, quiet stretch between them. The postings have not changed much in that time. The readers have. They are warier now.

In February of this year a regional bank in Charlotte, North Carolina, asked our blockchain developer staffing desk to look at a req its treasury technology group had posted six weeks earlier. The bank was building settlement for a payment stablecoin, the kind of product the GENIUS Act made possible in 2025, and the Office of the Comptroller of the Currency had just put out its proposed rules for bank stablecoin issuers. The group wanted one senior engineer to own the contracts. Just one.

The posting was titled “Blockchain Developer.” It listed eighteen technologies. Solidity, Rust, Go, Hyperledger Fabric, Corda, Ethereum, Solana, Polkadot, IPFS, web3.js, and eight more, several of which share nothing but the word blockchain. It drew 212 applicants in six weeks. I read them all.

Most of them matched the list, at least on paper. That should have worried someone. A handful claimed production experience with every item on it, which almost nobody has, and two of those would not turn their cameras on for a first call. The engineers the bank actually wanted had looked at the posting and moved on, because it did not say which chain the bank would deploy to, what language the contracts were in, or who would sign a release.

We rewrote it with their engineering director. It took a morning. The new title read “Senior Smart Contract Engineer, Payment Stablecoin Settlement (Solidity, Foundry).” The body named Ethereum mainnet plus one Layer 2, said the contracts would be reviewed by an outside auditor and by the bank’s examiners, and said the hire would be one of five signers on the upgrade multisig. Twenty-six people applied. The bank hired an engineer from the tokenization team at a Jersey City brokerage for $192,000 base, and her first day came five weeks after the new version went up.

Our blockchain developer hiring guide makes the point that the engineers you want in this market are rarely applying to anything. I agree. What I have watched happen instead is that they get a message, from us or from you, and then open the posting to decide whether to answer. The posting is read after the message, not instead of it. It has to survive that read. Most do not.

A word on incentives. KORE1 is paid when a seat fills through our blockchain recruiting team, and a clear, checkable posting will sometimes fill a seat with no recruiter involved at all. That is fine. A vague posting costs more of everyone’s time than it could ever earn us.

What Candidates Read Into the Title

A blockchain developer writes software for a blockchain, either code that executes on the chain itself or code that sends it transactions and reads its state. Most job openings under the title are for smart contract engineers, who write on-chain code in Solidity or Rust, but the title also covers protocol engineers who build the network itself and application engineers who connect wallets and back ends to it.

Those are different jobs. Very different. Our staffing page and the hiring guide both sort them, so I will not do it again here. What I want to add is what candidates infer from the words a posting uses, because they infer a lot, and quickly.

Naming the chain costs nothing, and it is the single fact candidates look for first. The Solidity Developer Survey 2025, with 1,095 usable responses from 87 countries, found 52% of respondents deploying to Ethereum mainnet, 40% to Base, 35% to Arbitrum, and 30% to Polygon. Those overlap heavily, so most engineers will have worked on more than one. They still want to know yours. Gas costs differ. So do the bridges and the risks that come with them, and someone with three years of Layer 2 work behind them will want to know whether this job means going back to mainnet prices.

Solana, Sui, Aptos, and the other non-EVM chains are a different pool. Rust or Move. Different account models. Different tooling. If the seat is on Solana, write the posting as a Rust posting with a chain attached, and most of what that side needs is already in our Rust developer job description template.

Foundry, Hardhat, and the Rest of the Toolchain Line

Smart contract engineers read the toolchain paragraph closely. Line by line. They are not being picky. The tools tell them how the team tests code that often cannot be fixed in place once it ships.

Foundry leads now. The same Solidity survey found 57% of respondents using it as their primary framework, up from 51% the year before, with Hardhat at 33% across its two major versions. That is not a verdict on Hardhat, which plenty of strong teams still run. It does mean a posting that names neither tells the reader nothing about how the team works, and a posting that names Truffle tells them the codebase is old. The survey found exactly one Truffle user. One.

The posting needs four facts, and your team already knows every one of them.

• The framework and the Solidity version. The survey found 86% of respondents on the 0.8 line, so the version matters mostly when it is something else. Say so if it is.
• What runs before a merge. Unit tests are assumed. Fuzz and invariant tests, static analysis such as Slither, and any formal verification are not assumed, and the candidates you want will look for them.
• Who audits the code, and how often. An outside firm before each release, a continuous audit arrangement, a public contest, or nothing yet. All four are honest answers. Pick yours.
• Whether you run a bug bounty. If you do, say whether this hire triages the reports, because that is a real and sometimes stressful part of the job.

If the code has not been audited yet, say that too. A senior engineer will find out in the first week regardless. They always do.

Who Holds a Key

Almost every blockchain posting I read leaves this out, and it is the question I hear most from senior candidates on a first call. Will I be a signer? And if so, of what?

On most production contracts, an upgrade, a parameter change, or a pause needs signatures from several people on a multisig wallet. Being one of those people is a responsibility with real weight. It can mean carrying a hardware wallet, answering a signing request at two in the morning, and checking a transaction by hand before approving it, because the screen showing it can be wrong. Some engineers want that trust. Others will turn down the job over it. I have seen both. Each is a reasonable position, and each person deserves to know before the interview.

One sentence covers it. “This role is one of five signers on the protocol’s upgrade multisig.” Or “Signing authority sits with the security team, and this role proposes transactions but does not sign them.” Incident on-call, if the team runs it, deserves a sentence too, with how often each person carries it. The blockchain developer interview questions we published include a section on key holders, and it pairs well with this line in the posting.

Your Posting Looks Like the Scam

Nothing about blockchain hiring changed more in the last year. Few hiring managers know.

On September 18, 2026, the FBI, the National Police Agency of Japan, and five other agencies in Japan, the United States, Australia, and Germany published a joint advisory on a North Korean group called WaterPlum, better known as Contagious Interview. The group poses as employers, often as AI, cryptocurrency, or NFT companies. From around December 2025 through July 2026 it infected at least 30,000 computers in more than 100 countries and drained funds or credentials from over 7,000 cryptocurrency wallets, worth about $10.7 million in all. Its primary targets were engineers and specialists in cryptocurrency, blockchain, and Web3.

The method is a job interview. A recruiter reaches out, the conversation goes well, and the candidate is asked to download a repository and run it to finish a coding assignment or fix a problem on the video call. One malware family named in the advisory, StoatWaffle, hides in blockchain-themed project repositories and runs as soon as the candidate opens the folder in VS Code and trusts it. No command needed. Just a click. The advisory tells developers to open unknown projects in Restricted Mode and check the tasks.json file first.

So a completely legitimate hiring process can look, step for step, like the attack. Exactly like it.

A consumer payments company in Lehi, Utah, learned that in 2025. Its take-home for smart contract candidates was a private GitHub repository with a failing test suite and instructions to clone it, run npm install, and make the tests pass. Normal enough. We had a strong Foundry engineer in the process, a woman who had spent four years at a lending protocol, and she declined the exercise and withdrew. She was polite about it. Firm, too. She said a colleague had been hit by a nearly identical request the month before and lost the contents of a hot wallet, and she no longer ran code from anyone she had not met in person. Two more candidates asked to do the exercise in a virtual machine. They were right to ask.

The company moved the exercise into a hosted development environment it controlled, one the candidate opened in a browser, and put three sentences in the posting. They told candidates who the hiring manager was, said every message about the role would come from the company’s own domain, and promised the process would never ask anyone to run code on their own machine. More candidates finished the exercise. Noticeably more. The next senior hire came from the first slate after the change.

If your code exercise asks candidates to run anything locally, change that first. Then say so in the posting. Plainly. The engineers most worth hiring are the ones most likely to have heard of Contagious Interview, and a posting that answers the question before they ask it reads as a company that knows its own industry. The risk runs the other way too. The same advisory describes North Korean IT workers applying for engineering jobs at crypto companies, and our cybersecurity staffing team spends more time on candidate verification for these seats than for almost anything else we fill.

Tokens Count as Compensation

These are the 2026 base ranges from our blockchain developer salary guide, which is the number I would start from before writing the compensation paragraph, along with total compensation at employers where tokens or equity are part of the offer.

The right column is where postings go wrong. Badly. “$160,000 to $190,000 plus tokens” tells a candidate almost nothing. How many tokens, on what vesting schedule, with what lockup after vesting, and at what price? Experienced engineers have watched grants go to zero, and they will value an undescribed token allocation at roughly that.

Some states want the description anyway. Washington’s pay transparency statute, RCW 49.58.110, requires employers with fifteen or more employees to post the wage range plus a general description of all the benefits and other compensation offered for the position. Tokens are other compensation. A Scottsdale, Arizona, startup we worked with last year had written “competitive token package” on a remote posting that Washington residents could apply to, and its outside counsel made it rewrite the line before the role went live again. The new version gave the grant size as a percentage of supply, the four-year vesting schedule, and the one-year lockup. Candidates asked better questions after that. Fewer, too.

Paying part of the salary in tokens is its own question. A messier one. The IRS treats virtual currency paid as wages as W-2 wages at its fair market value in dollars on the day it is received, subject to withholding and payroll taxes. So a token paycheck still needs a payroll department that can do that math every pay period. Most companies I work with pay the base in dollars and keep tokens in the grant, and I would say which one you do in the posting. It happens that the same federal advisory lists a request to be paid in cryptocurrency as one of the warning signs in a suspicious applicant. A posting that says “base salary is paid in U.S. dollars through payroll” closes that door for everyone.

What the Compliance Team Circled

Can we list five chains so the posting reaches more people?

You can, but a posting that names five chains usually draws applicants who have used all of them lightly and loses the specialists who have spent years on one.

If the roadmap really does cover several chains, say which one comes first and which ones are plans. Be honest.

Should the posting really say how much money the contracts hold?

A range is enough, and senior smart contract engineers expect one, because the size of the balance decides how careful the job has to be and how the team will judge their work.

Security people sometimes object that a number helps attackers. On a public chain the balance is already visible to anyone who looks up the contract address, so the posting reveals nothing an attacker could not find in thirty seconds. Where the contracts are not live yet, give the expected scale. “Designed to settle up to $50 million a day” is a perfectly good sentence.

Is it all right to pay part of the salary in our token?

Federal tax rules allow it, but the IRS treats tokens paid as wages as W-2 wages at their dollar value on the day they are received, so your payroll team inherits the withholding.

State wage payment laws have their own rules about how wages are paid, so employment counsel should see the plan first. Most candidates would rather have the base in dollars and the tokens in a grant anyway. Whatever you decide, put it in the posting in plain words.

Does the posting need to describe the code exercise?

Two sentences will do it, one saying where the exercise runs and one promising that nobody will be asked to run code on their own machine.

After the September advisory, experienced blockchain engineers have good reason to be wary of any interview that ends with “clone this and run it.” A company that names the format up front gets more finished exercises and fewer awkward withdrawals. It also gives the hiring team a simple rule. If a message about the role ever asks a candidate to run something locally, it did not come from you.

Our code has not been audited yet. Should the posting admit it?

Say it, along with when the first audit is planned, because a senior candidate will find out in week one and will judge the company more by the omission than by the gap itself.

Some candidates prefer it. Plenty of good engineers like joining before the first audit. They get to shape the code the auditors read. Others will only join a team that has been through a few, and the posting lets them sort themselves out.

What changes when the seat is a contract role?

$150 to $220 an hour is the usual rate for a senior protocol or Solidity contractor, and a contract posting should also say when the work ends, what gets delivered, and whether a permanent offer is possible.

Audit preparation, a migration to a new chain, and a launch with a fixed date all suit contract staffing. Security and audit specialists run higher, from $175 to $325 an hour for work before a launch. Our searches for Solidity and EVM engineers typically take three to six weeks, Solana and Rust six to ten, and senior auditors eight to twelve, so a deadline that is closer than that is a reason to start now. Promising conversion in writing is a commitment, so read up on how contract-to-hire staffing is structured first, and if it is permanent from the start, our direct hire staffing team runs those searches.

Write a Posting a Stranger Can Verify

The Charlotte engineer is still at the bank. In August the team opened a second seat, and she wrote the posting herself, and she added a line nobody had asked for, the contract addresses of the two production deployments, so candidates could read the code before the first call. Three of them did. One brought a question about the pause function that the team had been arguing about internally for a month. He got the job.

That is my standard now. A careful engineer, who has every reason to be suspicious of a stranger offering a job, should be able to check each claim in a posting. The chain, the code, the auditor, the signer arrangement, the pay, and the people. If any of it cannot be checked, the posting is asking for trust it has not earned yet.

When the draft is close, talk with a KORE1 blockchain recruiter about the seat. We fill these roles nationally, on contract, as contract-to-hire, and as permanent seats. When we check in twelve months later, 92 percent of those engineers have stayed with the client.
