Job description

At nsave, we’re redefining what’s possible in fintech. We are building a new kind of financial platform that empowers underserved communities to manage, protect, and grow their wealth. We’re looking for an exceptional Full-Stack Engineer to help us craft both the experience and the infrastructure that power our mission.

If you’re passionate about designing elegant user experiences and building the scalable, secure systems behind them, this is your chance to make a meaningful impact in a mission-driven startup backed by some of the world’s top investors.

Location: Full-time, on-site in London, UK (Spitalfields)

Why You Should Join Us

As a Full-Stack Engineer at nsave, you’ll own features end-to-end — from crafting intuitive, performant user interfaces to designing the APIs and services that bring them to life. You’ll collaborate closely with our CTO, CEO, and design and engineering teams to deliver a seamless and trustworthy financial experience for our users across multiple regions.

We’re backed by Sequoia Capital, Y Combinator, and SV Angel, and we’re looking for someone who thrives on building high-impact systems that make finance more accessible, inclusive, and resilient.

Responsibilities

Design, implement, and maintain scalable, secure, and performant applications across the stack.

Build rich, accessible, and responsive front-end experiences that make financial management simple and transparent.

Develop and own backend services and APIs that power our product ecosystem — from authentication to banking and compliance integrations.

Work closely with product, design, and operations to translate user needs into technical solutions.

Drive improvements in code quality, developer experience, and system reliability.

Balance fast iteration with technical rigor, ensuring our systems meet the standards required in a regulated fintech environment.

Champion best practices in testing, observability, and deployment for full-stack systems.

Qualifications

Strong full-stack fundamentals: you’re comfortable building both user interfaces and backend services.

Proficiency in TypeScript, React (or similar frameworks), and Node.js/NestJS.

Experience with relational databases (Postgres preferred) and designing clean, efficient APIs.

Understanding of cloud infrastructure (AWS, Docker, CI/CD pipelines) and modern DevOps practices.

Familiarity with secure coding and data privacy principles - ideally in fintech or other regulated domains.

A collaborative, product-focused mindset: you care about user experience as much as system performance.

Curiosity, empathy, and a drive to make technology serve real people’s needs.

Frontend: React Native, TypeScript

Messaging: Kafka

Our Values

Pride in Impact: We care deeply about building technology that changes lives.

Compassionate Action: We act with empathy and collaborate with purpose.

Creative Problem Solving: We’re curious, resourceful, and relentless in finding better ways.

Inclusivity: We foster a diverse environment where every perspective counts.
