Backend Engineer

Fuse is rebuilding clearing from the ground up. Fintech has gone global and emerging markets have become growth markets, transitioning from high risk jurisdictions to must have corridors, but clearing banks haven’t evolved. We believe the clearing stack needs to be rebuilt. Treasury pooling and/or stablecoins fix surface level issues, but no one is rebuilding the underlying infrastructure in each market - from correspondent nostro account networks to clearing on local central banks.

We’re building a new type of clearing bank, connecting globally important growth markets (such as the Middle East, China, India, Turkey and many more) to G7 currencies through named virtual accounts in every jurisdiction. We take quality very seriously - using our own direct central bank clearing where possible, applying for global banking licenses, operating a universal reliance KYC model - all to ensure the same few lines of code enables a correctly named payment from a local account in every market, making us the ideal clearing partner for any cross border payment.

The role

We are looking for an experienced backend engineer to join our team and help build the foundational infrastructure. You’ll be joining a small, cross-functional team focused on shipping real value quickly and building systems that are observable, reliable, and designed to evolve.

This role is ideal for someone who enjoys working in fast-moving environments, thrives in ambiguity, and cares deeply about building high-quality backend systems that solve real-world problems. We’re particularly looking for engineers with strong experience in distributed systems and an interest in working with Rust.

We don’t expect you to have experience with our exact stack—but we do expect you to bring deep engineering expertise, sound judgment, and a pragmatic approach to problem solving.

What you'll do

• Design and build backend systems for financial use cases

• Operate in a dynamic environment where requirements evolve as we learn
• Collaborate across the business to ship useful features quickly
• Build software you can observe, debug, and improve over time
• Apply domain-driven design principles where appropriate (e.g. event sourcing, read/write separation)

Requirements

• • Significant experience as a backend engineer, ideally in high-trust or high-growth environments
  • A strong understanding of distributed systems—you’ve worked on systems that communicate across services, regions, or failure boundaries
  • Interest in working with Rust professionally—commercial experience is a bonus, but personal projects also count
  • Familiarity with the financial or payments domain (or a willingness to learn fast)
  • A product mindset—you care about the “why” as much as the “how”
  • A pragmatic approach to solving problems—you know when to optimise and when to ship
  • A belief in observability and ownership—you’re curious about how things behave in production

Benefits

• A Macbook
• Opportunity to travel (if applicable)
• Flexible vacation policy
• Private Healthcare
• Employee stock ownership (ESOP)
• Flexible working and autonomy
• Pay it forward days - we offer 2 annual pay it forward days where you can take time to volunteer for a charitable cause that is important to you.
• Wellness days - we believe you can only work your best when you feel your best, and we know working at Fuse is intense, so we offer 3 wellness days every quarter where you can take time to re-energise.
