We are looking for a Senior Engineer to join our Loan Servicing team within our Product Engineering department.

Our Servicing team build the systems that keep our loans moving. As a senior engineer, you’ll play a critical role in evolving our loan infrastructure, ensuring accuracy, speed and simplicity. Our team are keen problem solvers, collaborators and innovators. This is a brilliant opportunity to get involved in a team that are core to what our customers experience once they take out a product with Funding Circle.

• You love working in a complex problem domain where you can have a real and substantial impact on the business

• You have an interest or experience in relational databases, automated testing, microservices and/or event-driven architecture

• You are a keen collaborator - you love to pair and believe that working together is smarter than working in a silo

• You proactively problem solve, identify and confidently mitigate risks, issues or address weaknesses that arise in your day-to-day

• You have a strong sense of initiative, seeking out answers where they may not immediately be clear and driving clarity from ambiguity

What we’re looking for

We value deep expertise, but a growth mindset and good energy are what really make our team click. We’re a group that chooses to lift each other up and think smart every day.

• Experience working in Ruby or Python

• Strong fundamental programming skills

• Ability to quickly grasp and understand complex back end systems

• It’s beneficial, but not essential if you have an interest in working with complex mathematical problems.

• Able to architect custom AI solutions and smart automated systems that are safe, maintainable, and aligned with our long-term mission

• Act as a technical bridge and mentor, training “builders" across the company to move from basic AI usage to sophisticated system creation.

We’re building a place where everyone truly feels they belong. Even if your past experience doesn't align perfectly with every requirement, we'd still love to hear from you.

Why join us?

We back you to build an incredible career and by joining us, you'll be part of one of The Sunday Times Best Companies to Work For 2026! As a flexible-first employer, we use a "best of both" approach.
