  • Own greenfield development while also improving and refactoring existing systems.
  • Ensure system reliability and performance through monitoring and observability.
  • Collaborate with cross‑functional teams including AI engineers, product managers, and designers to ship impactful features.
  • Participate in code reviews, architecture discussions, and technical planning.

Who You Are

  • 6+ years’ experience in backend engineering, building high‑performance, distributed systems.
  • Strong fluency in Java, with deep understanding of backend design patterns and principles.
  • Hands‐on experience with microservice architecture, APIs, and database systems (PostgreSQL, Redis).
  • Solid foundation in computer science, mathematics, or related fields.
  • Comfortable working in cloud environments (AWS).
  • Fast learner with a results‑driven, problem‑solving mindset.
  • Excellent communication and team collaboration skills.
  • Fluent in English and comfortable in a fast‑paced, high‑growth environment.

Nice to Have

  • Exposure to product‑focused engineering and building systems for scale.

Why Join Nevis?

  • Work alongside a high‑calibre founding team backed by some of the best investors in the world.
  • A fast‑paced, high‑growth environment with the opportunity to shape how the business operates.
  • Be part of a mission‑driven company transforming the wealth management industry with huge potential for global impact.
