Engineer - Data & Platforms; m​/f​/d) arbeitnow Bitcap HQ

As our Engineer
- Data & Platforms (m/f/d), you build and run the internal data products that our investment team, Quantitative Research and AI Engineering rely on every day: the pipelines, datasets, APIs and tools that turn a large and growing pool of financial and alternative data into something investors can act on. Our stack is Python, SQL, AWS, and Databricks.

You report to our Director of Engineering. This is a hands‑on engineering role: most of your time goes to designing, building, and shipping. The team is small, so you take ownership of real products early, and you get a manager and colleagues invested in your growth into investment and data‑platform topics. You work closely with Quantitative Research, AI Engineering, Product & Data, and the investment team, and we treat agentic AI as a default in how we build.

• Build and improve the internal products the investment and research teams use daily: data pipelines, datasets, APIs, and tooling, on top of our lakehouse and orchestration stack.

• Work directly with the teams you build for: take in their requests, triage and prioritise them, protect the integrity and consistency of the product, and explain features and implementation trade‑offs in clear, non‑technical language.

• Design, build, and operate reliable data pipelines, ETLs and integrations that handle complex financial and alternative datasets.

• Bring and reinforce good engineering habits in the team: automated testing at several levels, CI/CD, pull requests and code review, and clear documentation.

• Contribute to operational excellence: observability, monitoring, data quality, and secure data handling.

• Use agentic AI across engineering work (coding, review, testing, debugging, documentation) and help the team push these practices forward.

• 3 to 5 years of professional software or data engineering experience, building and operating systems in production.

• Strong Python and strong SQL, with clean, readable code and a good sense for data modelling.

• Proven engineering discipline: you write tests (unit, integration, data quality), work with CI/CD, and use pull requests and code review as a matter of course, and you can show how you helped a team adopt them.

• Clear communication with non‑engineers: you can explain what you built, why, and what it will and will not do, and you can say no constructively.

• Hands‑on use of AI across engineering functions, including frontier coding systems such as Claude Code and Codex, as a core part of how you work.

• Genuine interest in investing, financial markets and data, and the ambition to grow into these topics.

• Nice to have:
  Databricks or PySpark; data platform tooling such as orchestration (Airflow, Dagster or similar), lakehouse formats (Parquet, Delta, Iceberg) and AWS; experience with investment, financial or market data; building web frontends or APIs for internal…
