About the job

Full-Stack Engineer role at nsave is a hands-on, end-to-end engineering position in a London-based fintech company focused on providing secure financial services to people in financially unstable and inflation-affected regions. The company aims to “protect and grow the wealth of the financially excluded” by building USD accounts and investment platforms with a compliance-first and security-driven approach. As a Full-Stack Engineer, you will be responsible for developing both frontend and backend systems, creating intuitive and high-performance user interfaces, and designing scalable APIs and backend services. You will work with technologies such as TypeScript, React Native, NestJS (Node.js), Postgres, AWS (ECS, RDS), Docker, and modern CI/CD pipelines, while also contributing to system architecture, database design, and event-driven integrations like Kafka. The role requires strong engineering skills, a focus on secure coding practices, and the ability to build reliable systems in a regulated fintech environment. You will collaborate closely with product, design, and engineering teams to deliver seamless user experiences, improve system performance, and maintain high engineering standards. The position is ideal for someone who enjoys ownership, fast-paced development, and solving real-world financial problems at scale, with visa sponsorship available for eligible candidates.
