Role

Who you are

5+ years in Data Science / Product Analytics / Applied AI roles, with sustained product-level metric ownership
Production LLM Experience: In the last 1–2 years, you have built, shipped, or evaluated LLM-based systems (RAG, multi-step tool use, agents) as a core, primary job responsibility
Autonomous Quality Ownership: Proven track record of owning evaluation methodology or analytics for an entire product or end-to-end process (what to build vs. what NOT to build)
Fluent Python & SQL: Ability to write clean data pipelines, evaluation harnesses, and dbt transformation models directly
Statistical Rigor: Applied knowledge of sampling, hypothesis testing, variance analysis, and confidence intervals on noisy metrics
AI-assisted coding (Claude Code, Cursor, or Codex) is your default daily authoring environment for Python, SQL, and evaluation scripts—not something you occasionally experiment with
You can walk us through concrete work tasks from the last month where AI coding tools accelerated your engineering and data analysis

What the job involves

You'll join Finom’s AI Team as the founding IC dedicated to the quality, evaluation and telemetry of AI agents powering Finom's internal operations and tools (including Ops workflows and internal AI analytics engines across ~20 core processes)
Own and extend our offline/online evaluation suites across ~20 internal AI agent processes—datasets (capability + regression), LLM-as-a-judge rubrics, and deterministic checks
Establish pre-launch quality gates: enforce pass/fail thresholds in CI/CD pipelines before agent prompt, context, or tool changes hit production
Work directly with domain experts to label cases and resolve annotator disagreement—fixing definition criteria rather than averaging disagreement away
Build test datasets derived from real user & operational traffic (tickets, internal chats, colleague queries) rather than synthetic edge cases
Harden statistical methodology: handle judge drift, verbosity bias, non-determinism, and measure true metric shifts vs. noise
Translate quality numbers into operational decisions: run weekly syncs with process owners to define clear quality vs. cost/latency trade-offs

Our take

Financial services can be complicated and time-consuming, especially for smaller companies, early-stage businesses, and freelancers. And navigating everything from invoices to expenses can often pull focus away from actually running the business.

Founded by the team behind the online B2B bank Modulbank, Finom is the fastest-growing financial management platform for SMEs and freelancers. Its automated tools cover everything from expense tracking to e-invoicing to multi-banking, and it's even supported by partnerships with the likes of VISA and Klarna.

This rapid growth is backed by strong investor confidence, too, with some significant funding added to its name in 2025. The capital will support customer acquisition, product expansion, and strategic initiatives. And with ambitions to reach 1M business customers by the end of 2026, Finom is seriously setting its sights high.
