Senior Backend Engineer (Team Atlas)

Join Team Atlas as a Senior Backend Engineer, where you'll own critical systems end-to-end and make key architectural decisions. You'll build and operate backend services in Python on AWS, tackle hard backend problems, and work directly with Product and Design to shape future developments. This role offers a hybrid work model from our Berlin HQ, London office, or Iasi hub.

- The ability to work in a hybrid model from our Berlin HQ, the London office, or the Iasi hub. Please note that relocation assistance is not provided for this role
- At least 5 years of professional software engineering experience, with a proven track record of leading complex projects in a senior capacity (2+ years)
- Strong system design skills — you're comfortable making architectural trade-offs and defending them
- Depth in at least one of these areas: data pipelines and storage, event-driven architectures, caching and performance, or serverless systems. You don't need all of them
- Deep expertise in Python and building backend systems on cloud platforms (we use AWS)
- Strong communication and collaboration skills, with the ability to align technical and non-technical stakeholders on a shared vision
- We're eager to meet talented and driven candidates regardless of whether they tick all the boxes. We're looking for someone who will add to our culture, not just fit within it. We strongly encourage individuals from groups traditionally underestimated and underrepresented in tech to apply
- Apache Iceberg, AWS Athena, AWS Glue, or Apache Spark
- Streaming / real-time data pipelines (Kinesis)
- Serverless at scale (Lambda, SAM, CloudFormation)
- Multi-level caching strategies (Redis, DynamoDB, in-memory)
