About the Role
Join an engineering squad in our Berlin office focused on distributed systems and platform infrastructure. This role is primarily systems engineering with a focus on core software systems and data architecture, valuing engineering depth in building internal distributed solutions.
Responsibilities
- Design and build core low-level services and distributed runtimes for Nubank’s global data platform, with high fault tolerance, elastic scale and sub-second event availability.
- Lead the design of compute orchestration frameworks on large Kubernetes clusters, improving scheduling throughput and resource utilization for complex data pipelines.
- 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.
Requirements
- 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.
- Advanced proficiency in a systems-oriented language such as Go, Java, Scala, Rust or C++.
- Experience with database system architecture (storage engines, indexing, replication) and/or event-driven architectures using Apache Kafka.
- A track record of technical leadership: writing design proposals, aligning teams on complex technical decisions, and mentoring engineers.
