Your mission

At FlexPower, the quantitative trading team is using models and data to make decisions. We are our own customers, and we take that seriously. To move faster and smarter, we’re looking for a Low Latency Data Engineer with a passion for performance, precision, and clean systems. No stakeholder juggling, no long meetings — just deep technical work with direct impact.

Your profile

You enjoy

• Writing efficient C++ that delivers low-latency execution and high reliability.
• Organizing and querying large volumes of time-sensitive data using BigQuery.
• Getting the details right — from error handling to naming conventions — because precision matters.
• Collaborating in a team that values humility, kindness, and technical excellence.
• Taking ownership of your work from design to deployment — and beyond.

You can support the team with

• Building and maintaining low-latency, high-availability data pipelines in C++ and Python.
• Engineering performant and scalable data warehousing solutions in BigQuery, using advanced SQL features (UDFs, ITVFs, MTVFs).
• Deploying production systems using Docker, Git, and CI/CD best practices.
• Leveraging AWS services — including S3, ECR, ECS, Fargate, and Lambda — to create resilient cloud-native pipelines.
• Designing systems with high conscientiousness — anticipating failure modes, writing clean code, and documenting responsibly.
• Working in a collaborative, agreeable way that supports shared goals and constructive feedback.

Bonus if you bring

• Experience in short-term power markets.
• Day Ahead, Intraday Auctions and Continuous, Imbalance.
• EPEX SPOT, EXAA, Nordpool, and EEX.
• Relevant data like weather, trades, order book updates.
• Experience with infrastructure-as-code and cloud architecture best practices (e.g. Pulumi, Terraform, AWS Well-Architected Framework).
• Experience with data pipeline orchestration and monitoring (e.g. Airflow, DBT, Grafana) or MLOps tooling.
• Programming experience in Go or Rust.
• Fluency in German

Why us?

What we offer

• A deeply technical, fast-moving environment where you work with traders, not for them.
• Systems you build will be used in production immediately and scrutinized by your peers and the market — a rare and rewarding feedback loop.
• A high-agency team culture that rewards care, clarity, and cooperation.
