Role
Who you are
- 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 – whether for work or for fun. You use it to blast through boilerplate and research so you can focus on the hard parts: complex architecture, rigour and high-stakes decisions
Desirable
- 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
What the job involves
- 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 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
- Almost every repeat borrower goes through code we own. 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
- Your first project will be the re-architecture of our flex-loan repeat offer pipeline: the flow that decides who is eligible for a new loan, what they pay, and how much they can borrow. This area has been under-invested for years. Once the new pipeline is in place, product has a clear runway of features ready to ship on top of it
- You will own backend features end-to-end, from design through to shipping and monitoring them in production. Over time, you will pick up front-end work and grow into a full-stack role
- 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 benchmarks
Our take
UK SMEs are the backbone of a complex economy that is constantly changing, so the need for fast and responsive access to finance is becoming more and more important to ensure their success and growth. iwoca allows SMEs access to business loans in less than a minute, with its API and business marketplace partnerships.
With offerings like iwoca's, gone are the days where waiting up to eight weeks for a loan decision was viable. Its simplified business loans of £1,000 - £500,000 come with no fees attached, and applying online takes no more than five minutes. The ready availability of iwoca loans gives business owners a level of certainty, so that they can make instant decisions to help their business grow.
iwoca has made a number of partnerships with other players in the business finance space, including an impressive industry-first invoice checkout integration with QuickBooks. Funding raised by the company, which is now operating at net profitability, will enable it to meet a recent surge in demand for corporate loans and offer more to larger SMB businesses. And the company has made several billion in funding available to over 100,000 businesses since launching, positioning itself as a leading European fintech.

- Keep yourself healthy: We offer comprehensive health insurance and cash plans. You'll also get gym discounts and we host yoga classes in the office every week
- Start (and end) your day right: Each floor of iwoca HQ has a fully stocked fridge for breakfast and every Friday we unwind with beers and wine

Company values
- Motivated: Going to work shouldn't feel like a slog, so we want everyone in the team to personally care about what they're working on. We stay motivated by celebrating our wins, learning from our mistakes, and always looking for new gaps to step into
- Smart: At iwoca being smart isn't about what you know, it's about how you think. Smart thinking means looking at each problem by asking ‘why’ first, then figuring out ‘how’
- Humble: We know all ideas are flawed, all code has bugs, and everyone makes mistakes - it’s how we learn. For us, being humble means you question yourself first, rather than your team
- Growth Mindset: We think there's always a better way to solve a problem. So we never let ourselves get comfortable with being good enough
