Back End Developer

Software Engineer

Fully Remote

We’re partnering with a growing fintech business that is building modern, customer facing financial products at scale. The company is around 80 people today, with small, collaborative engineering teams and a strong product led culture. They are looking for a Software Engineer to join their backend team.

The Role

This is a backend-focused engineering role working across a modern cloud based platform. The company’s core stack includes Kotlin and PHP. They are actively moving more services and new development towards Kotlin, but PHP remains an important part of the estate and is not being phased out entirely.

You’ll work in a small, cross functional team alongside engineers, product managers and other stakeholders, contributing to the design, build and improvement of customer-facing systems. The role would suit someone who enjoys working in a pragmatic environment where engineers have ownership, move quickly and care about building reliable, maintainable software.

What You’ll Be Doing

You’ll be involved in building and improving backend services across the platform, contributing to new Kotlin based development while also working with existing PHP services where needed.

You’ll help design scalable, reliable systems, contribute to technical decisions, write clean and maintainable code, and work closely with product and engineering colleagues to ship meaningful improvements. You’ll also be expected to take ownership of your work, contribute to code reviews, support good engineering practices and help improve the platform as the company continues to grow.

What They’re Looking For

The ideal person will have solid backend engineering experience and be comfortable working in a cloud based environment.

You should have commercial experience with Kotlin or similar JVM technologies. You should be comfortable picking things up and contributing across the stack.

Experience in fintech, lending, payments, banking or regulated environments would be useful, but it is not essential. More importantly is that you are a strong engineer who can work independently, communicate well and contribute positively to a small engineering team.

Key Skills

• Commercial backend engineering experience
• Kotlin and/or PHP experience
• Comfortable working with cloud based systems
• Strong understanding of APIs, services and backend architecture
• Good coding standards and attention to maintainability
• Experience working in small, collaborative product engineering teams
• Comfortable working remotely
• Pragmatic, curious and keen to keep improving

Nice to Have

• Experience in fintech, lending, payments or financial services
• Experience with cloud-native platforms and modern engineering practices
• Exposure to legacy modernisation or moving services from one stack to another
• Experience working in a scale-up or smaller product-led environment

Working Model

This is a fully remote role, open to candidates across the UK and Europe. Candidates based in Europe will be employed via an Employer of Record, so you will need to have the right to work in your country of residence.

Why Join?

This is a good opportunity for an engineer who wants to join a growing fintech business, work in a small team, and have real ownership without being lost in a large engineering organisation.

You’ll get the chance to work on meaningful product challenges, contribute to a Kotlin-focused technical direction, and still gain exposure to a broader live platform where PHP remains part of the stack.
