Senior Data Engineer

KeyrockNetherlandsRemoteFull-time1 week ago

Keyrock is hiring a Senior Data Engineer to be an early hire in its Central Data Team, building the Keyrock Data Platform for real-time data across trading, wealth management, risk, finance, and compliance. The role requires 8+ years of production data systems experience, strong Python and SQL, and deep expertise in streaming, time-series, and lakehouse architectures.

What you'll do

Build streaming and batch pipelines that ingest, normalise, and distribute market, trading, and portfolio data, resilient to feed and exchange failures.
Build self-serve tooling (SDKs, patterns, templates, AI agents) so other teams publish, consume, and build on data products without waiting on us.
Own data contracts and schema evolution. Keep schema changes from turning into multi-team coordination events.
Design the lakehouse and time-series layer around consumer query patterns.
Build and evolve the Data Governance and Data Quality Framework: stale-feed detection, schema validation, range checks, idempotent writes, lineage, ownership, self-healing.
Build the derived analytics the business runs on: cross-exchange spreads, VWAP at depth, order book microstructure for the desks; portfolio views, exposure, performance for wealth and asset management.
Make observability, cost, and performance first-class from day one.
Treat infrastructure as code (Docker, Terraform, CI/CD) alongside our Central Infrastructure Team.
Work in the open: write things down, partner closely with Architecture, Infrastructure, Platform, and the rest of the teams.
