As an Evals Engineer, you will own how Profound knows its AI is right. At Profound, measurement is the product: when a Fortune 500 CMO sees their brand's visibility drop in ChatGPT, they act on that number. No public benchmark measures whether a model attributed a citation correctly or ran a competitive analysis well, so we build our own. You'll decide what gets measured, why, and how results shape what we ship. Every product runs through the evals you design, so your impact compounds across all of them.
What you'll do- Build Profound's eval system: golden datasets, scorers and LLM judges, programmatic verifiers, regression alerts, and dashboards
- Write evals for every pipeline behind the product: brand extraction, visibility scoring, sentiment, FactCheck, and citation classification
- Define what a great, mediocre, and broken AI Marketer run looks like, and measure it across multi-step tool use, analytical correctness, and content quality
- Study how answer engines behave across runs, platforms, regions, and personas, and design the sampling and statistics that keep customer-facing numbers trustworthy
- Close the loop from real usage: collect customer signals, cluster failure modes, and turn regressions into permanent guardrails
- Build tooling for debugging model and agent behavior, plus the labeling workflows and annotation guidelines behind our ground truth
- Make evals part of how we decide things: wired into CI, launch reviews, and model selection
Who you are- 3+ years building evaluation or measurement systems, whether AI evals, experimentation, ranking, or search quality
- Strong Python and data skills, with a track record of shipping production systems
- Deep familiarity with LLM evaluation: LLM-as-judge, benchmark design, agent harnesses, calibration, and significance testing
- Sound experimental design, and the instinct to separate signal from noise in non-deterministic systems
- Strong opinions about how models and agents behave, and you keep up with current research
- You believe a good eval is clear, reliable, and hard to game
- Work that shows how you think: shipped benchmarks, datasets, open-source tools, or publications
- Comfortable operating in a fast-paced startup environment with rapid iteration cycles
Nice to have (optional):- Experience with search, retrieval, citation, or fact-verification systems
- Publications at venues like NeurIPS, ICML, ICLR, ACL, or COLM
