Backend Engineers

Full-time

LOCATION

Remote and HQ in Edinburgh when required

Overview

We’re looking for backend engineers who like to build clean, reliable systems and understand how things connect behind the scenes. This is core infrastructure work — the pipes, not the paint. You’ll help power the next generation of financial products by writing code that is scalable, secure, and easy to maintain.

Whether you’re working on payment flows, data architecture, or customer account logic, you’ll be solving real problems that affect real people. If you take pride in simplicity and getting things done, we’d like to talk.

What You'll Do

  • Design, build, and maintain backend services and APIs for Caledonia’s core platform
  • Collaborate with product, frontend, and ops teams to ship reliable features quickly
  • Write clean, well-documented code that can scale across multiple products
  • Optimise systems for performance, security, and resilience
  • Help define backend architecture, database models, and infrastructure choices
  • Participate in code reviews and technical discussions that move the work forward
  • Contribute to a growing culture of engineering quality and thoughtful development

What You'll Bring

  • 3 or more years of backend engineering experience, ideally in a fintech or startup setting
  • Strong knowledge of at least one backend language (Kotlin, Python, Go, Java, or similar)
  • Experience with building APIs, working with relational databases, and designing scalable systems
  • Understanding of secure coding practices and how to protect sensitive data
  • A pragmatic approach to architecture and a sharp eye for what matters
  • Comfort working in small teams where ownership is shared and autonomy is expected
  • Willingness to work with ambiguity and help shape technical direction as we grow

About Caledonia

Caledonia is a next-generation financial company focused on serving freelancers, creators, and independent professionals. We’re building adaptive, AI-powered banking infrastructure that challenges the legacy systems of the past.

We are not yet a licensed EMI or bank. That’s what we are working toward — with your help.

Who You’ll Work With

This role reports to the Head of Engineering and works closely with product managers, frontend developers, and the founding team. You’ll be part of the team that builds and maintains Caledonia’s technical core.
