Role Overview
We're looking for a back-end engineer to join the Repeats team. You will work on the services that decide which repeat customers get a loan, at what price, and how much they can borrow. These sit at the heart of iwoca's back book.
The Company
Imagine a world where every small business has the power to thrive. That's the world we're building at iwoca. Since 2012, we've revolutionised how these businesses access finance, turning what was once a lengthy, frustrating process into something remarkable: funding that's fast, flexible, and actually works for modern businesses. We combine cutting-edge technology and data science with genuine human understanding to make finance feel less like a barrier and more like a superpower.
The Team
The Repeats team is one of iwoca's funnel teams. We grow customer lifetime value after a business's first loan. That means we own the underwriting, pricing, and product experience for two segments that make up most of iwoca's back-book value: top-up customers who borrow again while still repaying, and loan-ended customers who return for a new loan. The team is cross-functional – backend, frontend, product, design, data science and analytics – shipping behind split tests and measuring impact in Looker rather than on gut feel.
Responsibilities
- Work on the systems that shape every repeat customer's offer, and move the metrics behind iwoca's back-book performance.
- Ship features that make it faster and clearer for small business owners to access follow-on funding.
- Work through the full development lifecycle – from technical design and implementation to rollout behind a split test – on well-defined components.
- Maintain and support the core services behind repeat lending: the lending_decision app inside iwoca-django, the repeats pricing and offer-amount services, and the customer account pages.
- Help monitor production and troubleshoot issues when they come up.
- Work closely with Product, Design, Data Science and Analytics to build solutions that make sense technically and land well for customers.
- Show up to team rituals – stand-ups, retros, planning – with context and questions.
- Write clean, well-tested Python, and take part in code reviews to learn from teammates and keep quality high.
- Pick up front-end work in Pandora (React, TypeScript) so you can own features end-to-end over time.
Salary
We expect to pay from £60,000 - £80,000 for this role. We routinely benchmark salaries against market rates, and run quarterly performance and salary reviews.
Culture and Growth
At iwoca, we prioritise a culture of learning, growth, and support, and invest in the professional development of our team members. We value thought and skill diversity, and encourage you to explore new areas of interest to help us innovate and improve our products and services.
Benefits

- 25 days’ holiday per year, an extra day off for your birthday, the option to buy or sell an additional five days of annual leave, and unlimited unpaid leave.
- A one-month, fully paid sabbatical after four years.
- Instant access to external counselling and therapy sessions for team members that need emotional or mental health support.
- 3% Pension contributions on total earnings.
- An employee equity incentive scheme.
- Generous parental leave and a nursery tax benefit scheme to help you save money.
- Electric car scheme and cycle to work scheme.
- Two company retreats a year.
- A learning and development budget for everyone.

Offices
Offices in London, Leeds, Berlin, and Frankfurt with plenty of drinks and snacks. Events and community-led groups, including running groups, padel, and monthly ping-pong and pool competitions.
Essential
- Comfortable writing clear, testable Python. You do not need to be an expert.
- 1+ years of commercial engineering experience.
- Working knowledge of relational databases. We use PostgreSQL.
- Curious about the full stack and up for picking up front end (React, TypeScript) over time.
- Clear written and spoken communication. You can explain technical work in a way non-engineers can act on.
- You care how your work affects customers, and use experiments and metrics to guide decisions.
- You have experience of writing automated tests and take code quality and safe releases seriously.
- You use AI (Cursor, Claude Code or similar) in your daily flow.
Bonus
- Familiarity with Python web frameworks (Django, FastAPI).
- Exposure to Docker, AWS or Kubernetes at any level.
- Any exposure to data tooling such as Snowflake or Looker.
- A strong numerical or technical background, with a degree in maths, physics, computer science, engineering, or relevant industry experience.
