Adyen is hiring a Senior Senior ML Engineer — payments risk on the Risk ML team (Hybrid · Amsterdam, Netherlands). This is a hands-on role in LLM & generative AI—not a generic “AI enthusiast” post.
You will own LLM features, retrieval, agents, and evaluation end to end: problem framing, offline evaluation, safe rollout, and iteration from production signals. Success is measured with clear metrics (quality, latency, cost, or business KPIs)—not slide decks alone.
Adyen processes payments globally for platforms and enterprises from Amsterdam headquarters.
Risk ML engineers build real-time fraud and graph features at transaction scale.
What you will do
- Ship production payments fraud ML with offline evals, monitoring, and safe rollout.
- Work with product and domain experts on requirements and trade-offs.
- Improve data pipelines, labeling, and metrics tied to business KPIs.
- Document runbooks for on-call and customer-facing teams.
What we look for
- Strong Python and modern ML/LLM stack with shipped features.
- SQL, experimentation, and clear communication to stakeholders.
- Eligible to work in the listed country; professional English required.
