Visit our Institutional Page You will join an engineering squad in our Berlin office working on distributed systems and platform infrastructure.

Our products serve analytics engineers and business teams across the company, but this is primarily a systems engineering role (roughly 75% core software systems engineering, 25% data architecture).

We value engineering depth: we build internal distributed solutions and understand the runtimes underneath, rather than only orchestrating managed tools.

As a Senior Software Engineer you will shape the architecture of our low-level infrastructure, orchestration frameworks and storage engines.

You will lead technical design, resolve systemic bottlenecks in compute and streaming layers, and mentor engineers across squads, working with colleagues in Berlin, the US and Latin America.

• Design and optimize high-throughput streaming and storage architectures using Apache Kafka and distributed database internals for mission-critical financial workloads.
• Find and remove performance, network and storage bottlenecks across the infrastructure stack to reduce latency.
• Work with Analytics Engineering leads and platform users to define internal APIs, developer toolchains and data modeling practices that speed up developers company-wide.
• Set standards for resilience testing, automated failover, observability and architectural documentation.
• Требования
• Substantial experience designing, scaling and operating mission-critical distributed systems and backend architectures in high-throughput production environments.
• Strong practical knowledge of container orchestration and systems management at scale, ideally Kubernetes internals and custom controllers or operators.
