At Sytac, we build high-performing engineering teams for leading organizations. We combine a pragmatic, people-first culture with technical craftsmanship, giving engineers autonomy in real production environments.

For one of our key clients in the Netherlands, we are looking for a Data Engineer – Market Data & Reporting Platform to join a fast-paced team that ships frequently and iterates quickly. You'll build and maintain data pipelines integrating with financial vendors, automate reporting workflows, and help evolve infrastructure across multiple environments in a team where clean code, strong fundamentals, and AI-assisted development are part of how everyone works every day.

• Design, build, and maintain Airflow-based data pipelines and automation workflows.

• Integrate with external financial data providers and internal services.

• Collaborate closely with the wider team to scope, review, and ship changes end-to-end.

• Use AI coding assistants as a genuine force multiplier — this is part of the daily workflow, not optional.

What we're looking for

• Strong Python fundamentals, you write clean, well-typed, testable code as a matter of habit.

• Strong SQL skills, you write and optimise complex queries without reaching for an ORM first.

• Hands-on PostgreSQL experience: indexes, query plans, schema design.

• Experience with workflow orchestration and pipeline tooling, Airflow experience is directly relevant.

• Comfortable working in a containerised, cloud-native infrastructure.

• Able to move fast without cutting corners, you know when to slow down and when to ship.

• Proactive communicator who picks up context quickly in a busy, high-throughput environment.

• Confident using AI coding assistants as part of your daily workflow.
