Senior Software Engineer (m/f/d) Data

## How you'll make an impact:

• drive projects end to end: clarify the problem, shape the solution, scope the work, and lead delivery through implementation, testing, deployment, and operation
• build production services, pipelines, and data products in Go and Python, with clear interfaces, automated tests, and strong observability
• design schemas, data contracts, and domain models that evolve safely, handle late-arriving data, and answer real business questions
• build in data quality checks, lineage, freshness monitoring, and clear ownership
• operate and improve the systems you build, including incident response, reliability, performance, and cost efficiency
• work with product, engineering, analytics, and data science to agree priorities and resolve trade-offs and support other engineers through mentoring, code reviews, and clear documentation

## What you'll need:

• senior-level experience delivering and operating production systems in a cloud environment. Experience with AWS or Palantir Foundry is useful, but experience with other cloud platforms is equally welcome
• a track record of building production services in Go or another statically typed language, alongside solid Python skills and the ability to work across our stack
• strong software engineering fundamentals, including maintainable code, automated testing, API design, and observability
• demonstrated ownership of projects from problem definition to production: you turn open questions into a workable plan, make sound technical decisions, and drive delivery while maintaining engineering quality
• experience with data modeling and reliable data processing, or strong transferable backend skills and the ability and motivation to develop that expertise
• clear communication, effective collaboration with technical and nontechnical colleagues, and experience helping other engineers develop
• the ability to learn quickly, work through unfamiliar problems, and make practical trade-offs around reliability, performance, and cost
• experience building recommendation services, working with lakehouse platforms, or handling high-throughput processing is a plus
