Nubank is a Brazilian digital bank founded in 2013 that began by issuing a no-fee purple credit card to customers frustrated by the branch banking oligopoly, and it has grown into one of the largest financial institutions in Latin America by customer count.

About the role

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.

What you will do

  • 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.

What you bring

  • 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.

Nice to have

  • Experience building internal developer platforms, custom compute engines or low-level database products.

  • Experience with data platforms or compute runtimes that support production AI/ML training and inference.

  • Familiarity with multi-region AWS networking, security, IAM and compute.

  • Involvement in open-source distributed systems projects (e.g. Kubernetes, Kafka, data orchestration).

Location and working model

This role is based in our Berlin office with a hybrid model: two days per week in the office, in line with Nubank’s Back to Teams policy. Our working language is English. Relocation support is subject to internal mobility review.

What we offer

  • A base salary of €78,720 - €98,400 gross per year, depending on experience and skills

  • A competitive Restricted Stock Unit (RSU) package in addition to your base salary

  • Additional benefits

Equal opportunity

We believe diversity makes our products and our teams better. We welcome applications from everyone, regardless of gender, ethnic origin, religion or belief, disability, age, or sexual identity. Severely disabled applicants with equivalent qualifications will be given preference.
