Backend Engineer - Investments & Savings

Location:Berlin, Barcelona

Hi, I'm Oussama Salimi, the Engineering Manager at N26, and I am looking for a Backend Engineer to join the Investments team here at N26.

Why is this role exciting and why should you apply?

• Democratize wealth: You will build a secure, real-time trading platform powering everything from Crypto and Stocks to ETFs and Managed Funds.

• High-stakes engineering: Operate at the thrilling intersection of high-speed trading and strict financial regulation where markets move fast.

• True autonomy: You are an active partner in shaping the product, not just a ticket taker. We trust you to be the owner of the delivery.

• Get Stuff Done Days (GSDD): Every six weeks, take two days of dedicated innovation time to explore new tech stacks, fix nagging bugs, or prototype outside the roadmap.

In This Role, You Will:

• Write high-quality, performant code (primarily Kotlin) and navigate the codebase fluently.

• Handle deployment, bug fixing, and incident handling with a high level of independence, taking features from concept to production.

• Act as a sparring partner for Product Managers during Product Discovery, ensuring technical decisions support the user experience.

• Question the status quo by asking "why are we building this?" and "is there a simpler way?"

• Identify knowledge gaps and technical problems, taking active ownership to address them without waiting to be told.

• Share your learnings from GSDD projects with the wider team, turning individual curiosity into collective knowledge.

• There will be a lot more too, this is a role that will require a lot of flexibility.

What you need to be successful:

• Proven experience as a Software Engineer taking features from concept to production with minimal supervision.

• A track record of thriving in dynamic environments where requirements evolve rapidly.

• A growth mindset: you treat feedback as a tool for engineering excellence and have a specific plan for your own learning.

• An "evidence over opinion" approach: you couple every critique of a problem with a practical proposal for its solution.

Skills:

• Strong proficiency in backend development, with Kotlin being our default for new services.

• Experience working with Distributed Microservices and Event-Driven Architecture (Kafka).

• Good understanding of cloud infrastructure and containerization (AWS, Kubernetes, and Docker).

• Experience with observability and monitoring tools (Datadog, ELK/OpenSearch).

• Resilience and proactive communication: you know how to navigate unresponsive stakeholders and unblock yourself.

• Constructive dissatisfaction: you are a "System Improver" who proactively fixes broken processes.

Interview Process And What To Expect:

• Initial Recruiter Screen

• Codility Test

• Pair Coding 

• Systems Design

• Behavioural Interview

What’s In It For You
