Senior Data Engineer — AI feature store & streaming

PolderPay is hiring a Senior Senior Data Engineer — AI feature store & streaming on the Data platform team (Hybrid · Amsterdam, Netherlands). This is a hands-on role in risk & decision ML—not a generic “AI enthusiast” post.

You will own real-time scoring, monitoring, and governance 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.

Amsterdam hybrid.

PolderPay needs someone who can move real-time scoring, monitoring, and governance from experiment to production—with tests, monitoring, and stakeholder-ready communication.

The Data platform group partners closely with product and domain experts; you will translate ambiguous requirements into measurable ML or LLM outcomes.

What you will do

• Design and ship real-time scoring, monitoring, and governance with offline evals, dashboards, and rollback plans.
• Improve datasets, labeling, and metrics that correlate with user or business outcomes.
• Review model changes for safety, bias, latency, and infrastructure cost before wide release.
• Document decisions so on-call, support, and compliance teams can act without guesswork.
• Join design reviews and pairing sessions with engineers and domain experts.

What we look for

• Demonstrated production use of core skills such as Python, SQL, Snowflake, AWS—with repos, writeups, or metrics we can verify.
• Comfort operating the listed toolchain (dbt, Docker) in real environments—not tutorials only.
• Ownership of at least one feature or model from design through post-launch review—including failure modes you handled.
• Clear communication on trade-offs (quality, cost, latency, safety) with product and non-technical stakeholders.
• Eligible to work in Netherlands (or remote policy as stated in the listing).

Benefits & ways of working

• Bike scheme, lunch, parental leave.
