What they need
AI Engineer | Agent Evals & Model Quality
Own how a production AI company decides whether its agents are good enough to ship.
I’m partnering with a technical, founder-led team hiring an AI Engineer to build the evaluation systems behind its platform.
You’ll own:
- Evaluation frameworks for multi-step agents and tool use.
- Golden datasets, benchmarks and regression suites.
- LLM judges, deterministic graders and human evaluation workflows.
- Model comparisons across quality, latency, reliability and cost.
- Feedback loops that turn production failures into better agents.
The team wants someone who has built production AI/ML systems, writes strong Python and can explain what they personally designed, shipped and improved.
Around 5+ years of software engineering experience is the guideline. Exceptional relevant ability and ownership matter more than a rigid experience threshold.
This should appeal if you want substantial technical responsibility and a direct say in how the product develops.
Message me with your resume and a brief example of an evaluation or production AI system you’ve owned.
Other offers great for you!
