Nubank Lead Software Engineer at Nubank designs, builds, and operates distributed backend services and APIs supporting core platforms globally. The role emphasizes end-to-end ownership and collaboration with data, ML, and infrastructure teams for scalable platform solutions.

Responsibilities

As a Software Engineer, you will join a small, senior group shaping the core technology that powers Nubank globally — from data and experimentation platforms to shared services that support products across multiple business units and geographies.
The work is highly 0→1, with a strong emphasis on long‐term impact, technical quality, and global scale rather than one‐off features.
You'll be responsible for
Designing, building, and operating distributed backend services and APIs that support core platforms used by multiple product teams worldwide.
Owning services end‐to‐end — from architecture and implementation to observability, reliability, and continuous improvement in production.
Defining clear contracts, SLOs, and guardrails so internal teams can safely build on top of the platforms you own.
Collaborating closely with data, ML, and infrastructure engineers to turn models, datasets, and lower‐level components into robust, easy‐to‐use internal products.
Leading 0→1 and modernization initiatives, making pragmatic trade‐offs and setting technical standards for high‐leverage systems.
We are looking for a person who has
Solid experience as a backend or platform engineer, owning production systems end‐to‐end (design, implementation, operations, and ongoing evolution).
Proven track record working with distributed systems at scale and building APIs or microservices on modern cloud infrastructure.
Experience building or supporting platform‐level services where many teams depend on your systems for their day‐to‐day work.
