ML Engineer Staffing That Finds the Builders, Not the Buzzwords
We place production ML engineers across the U.S. Snowflake, PyTorch, Kubernetes, MLflow. Contract, direct hire, or project-based. We’ve been doing this before most companies had an AI roadmap.

KORE1 places production ML engineers across the U.S., averaging 17 days to hire with a 92% 12-month retention rate, specializing in domain-scarce roles where Snowflake, PyTorch, and healthcare ML expertise overlap.
Most ML job descriptions are written by people who’ve never actually hired ML engineers before. You see “TensorFlow,” “PyTorch,” “experience with large datasets” and nothing that tells a real recruiter what the role actually needs. We’ve been placing ML engineers since before most companies had an AI roadmap. That matters. Especially when the search gets complicated.
ML engineer staffing is a specialty within our broader IT staffing services practice. We source across the full production ML stack, including Snowflake, Databricks, Spark, Kubernetes, MLflow, scikit-learn, and PyTorch, and our recruiters know how to tell the difference between a candidate who’s deployed models at scale and one who’s only worked in notebooks. Matters a lot.
What Makes ML Hiring Hard for Most Companies
Production ML engineers don’t look like data scientists on paper. The resume reads similarly, but the mental model is different. A researcher optimizes for accuracy. A production ML engineer optimizes for latency, reliability, and the ability to retrain a model at 2am without paging anyone.
We’ve closed ML searches where the hiring manager’s first draft of the JD said “PhD required, experience with BERT.” The search that closed in 11 days used a candidate with a master’s degree and five years of MLOps experience. The PhD candidates were still being interviewed at another firm three months later.
If your last recruiter sent 12 resumes and none had touched a real production pipeline, that’s the problem. Common problem. We fix it.

From MLOps to Healthcare ML, We’ve Filled the Hard Ones
Some source in a week. Others take longer. We placed a healthcare ML engineer for a clinical oncology AI platform at a Southern California medical center. The role required active Snowflake experience plus oncology domain knowledge. The national candidate pool for that combination was roughly 30 people. Not many. We found two finalists in three weeks.
- Machine Learning Engineer
- MLOps / ML Platform Engineer
- Applied Scientist (with production mandate)
- Computer Vision Engineer
- NLP / LLM Engineer
- Healthcare ML Engineer
- Snowflake ML Stack Engineer
- ML Infrastructure Engineer
- ML Tech Lead / Architect

How We Work With Your Team
Contract
Bring in ML expertise for model builds, replatforming, or interim pipeline ownership without a permanent commitment. No long-term risk.
Contract-to-Hire
Test real-world fit before locking in. Especially useful when the role definition is still evolving.
Direct Hire
For teams that need a full-time ML engineer who’ll own the stack long-term. We source, vet, and close.
Project-Based
Engage ML architects or senior engineers for defined scopes, model audits, or accelerated builds.
How an ML Engineer Search Actually Runs
We define what good looks like for your stack
Not just the job description. The actual success criteria, the production environment, the team dynamic, and what the model needs to do at 3am when something breaks.
We surface candidates with real production experience
Our recruiters screen for deployment history, not notebook portfolios. We look for latency awareness, retraining pipelines, and ownership of model behavior in production.
We manage the search from intake through close
Interviews, offers, counteroffers, post-hire check-ins. We stay engaged because our 92% 12-month retention rate depends on it.
We’ve Placed ML Engineers Where the Stack Gets Complicated
Healthcare, fintech, and oncology AI aren’t generic ML searches — the candidate profile is completely different from a standard software search. A candidate who built great recommendation systems for an e-commerce platform isn’t automatically the right fit for a clinical decision-support system that ingests DICOM data and surfaces oncology risk scores in near-real time. Different problem. Different hire.
We’ve placed ML engineers at clinical AI teams connected to major Southern California medical centers, including organizations like CHOC and City of Hope, where Snowflake served as the data substrate for oncology model inputs. Those searches required candidates with both the technical depth and the healthcare domain fluency. We found them.
This is the production ML context behind our broader AI and ML engineer staffing practice. The harder the domain overlap, the more recruiting depth matters. According to the Bureau of Labor Statistics 2025 Occupational Outlook Handbook, ML-related roles are projected to grow 36% through 2033, further compressing an already scarce pool for domain-specialized candidates.
Common Questions
How much does ML engineer staffing typically cost?
Most ML engineer placements through a staffing firm run 18 to 25 percent of first-year salary for direct hire, with contract rates between $85 and $160 per hour depending on stack and domain. KORE1 gives you a clear fee structure before the search starts. Contract and contract-to-hire rates vary most by specialization. Healthcare ML and MLOps platform roles trend toward the higher end because the candidate pool is narrower and the vetting is more involved. For full compensation benchmarks by specialization and seniority level, see our ML engineer salary guide.
How long does a typical ML engineer search take?
KORE1 averages 17 days for IT hires overall, but specialized ML roles can run 3 to 5 weeks depending on requirements. If your role needs Snowflake plus healthcare domain knowledge plus MLOps experience simultaneously, that’s not a standard search. We’ll tell you upfront what the candidate pool actually looks like. A shorter timeline estimate from another firm isn’t faster. It’s less honest. Full stop.
What’s the real difference between an ML engineer and a data scientist?
ML engineers build and maintain the production systems that serve models. They own latency, reliability, and retraining pipelines. Data scientists typically develop and evaluate models, often in notebooks, often without deployment responsibility. The line has blurred in some orgs. But when you need someone who’ll own the model in production and keep it running when something breaks, that’s an ML engineer. If your search is for the latter, see our data scientist staffing practice.
Contract or direct hire for an ML role — which makes more sense?
It depends on timeline and role clarity. Contract works when the scope is defined and the need is immediate. Direct hire makes sense when culture fit matters as much as technical skill and you need someone who’ll own the stack for years. Contract-to-hire is often the right call when the role definition is still evolving or when you want to see how a candidate handles production pressure before committing. There’s no universal right answer, and we’ll help you think it through.
What ML tech stacks does KORE1 recruit for?
We regularly place engineers with hands-on experience in PyTorch, TensorFlow, scikit-learn, Spark, MLflow, Kubeflow, Vertex AI, SageMaker, Databricks, and Snowflake. Most production ML environments are multi-tool and our sourcing reflects that. We’re not looking for someone who knows one framework. We’re looking for someone who can navigate the full stack your team actually runs.
How does KORE1 vet ML engineers differently from other staffing firms?
92% 12-month retention rate. Start there. Our recruiters know the difference between someone who’s run experiments and someone who’s owned a model in production. It shows up in how a candidate talks about latency budgets, about model drift, about what they actually do when a model underperforms at 3am. We don’t keyword-match resumes. We recruit.
Can KORE1 place ML engineers with specific domain expertise in healthcare or oncology AI?
Those are exactly the searches where our depth pays off. They take longer and we’ll say so upfront — no false timelines. We’ve placed ML engineers at clinical oncology AI platforms where the role required active Snowflake experience, healthcare data fluency, and model deployment skills simultaneously. The right candidate exists. The pool is just smaller. That kind of search is exactly where our sourcing depth and 15-plus years of average recruiter experience pay off most.
