About the job

nsave is a London-based fintech company on a mission to protect and grow the wealth of financially excluded individuals living in high-inflation and unstable banking environments. As a Backend Engineer, you will design, build, and operate secure, scalable, and highly reliable backend systems that power core financial products, including authentication, transactions, compliance, and banking integrations. Working closely with the CTO, CEO, and engineering team, you will own critical backend services end-to-end, balancing rapid iteration with the rigor required in a regulated fintech environment. The role requires strong expertise in TypeScript and NestJS, experience with PostgreSQL, AWS infrastructure, Docker, CI/CD pipelines, and event-driven systems such as Kafka, along with a security-first mindset. nsave offers a high-ownership, mission-driven environment, comprehensive benefits, and visa sponsorship for eligible candidates.
