Role
Who you are
- Advanced proficiency in software development
- Experience building and shaping large systems in complex business domains
- Experience building robust systems where the 'product' is high-quality data and you can 'speak the language' of analysts and data scientists
- Confidence to work closely with partners from other disciplines to challenge assumptions and discover underlying problems
- Demonstrable leadership skills: you have mentored juniors and inspired teams to deliver cross-functional projects. You can balance hands-on coding with strategic planning
- You use AI (like 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 decision-making
Desirable
- A strong numerical or technical background, ideally with a degree in physics, engineering, maths, computer science or a related field
- Experience building and maintaining analytics systems
- Experience with Python, Snowflake, or PostgreSQL
- Experience working on feature-management systems such as feature services or features stores
- An understanding of complex data systems, including event-sourced data models
What the job involves
- As Tech Lead, you’ll be responsible for the engineering systems that underpin Credit Risk modelling at iwoca
- You’ll focus on the platform, pipelines, and production systems around the models, rather than building models yourself
- This is a hands-on technical leadership role, combining technical direction, line management, and individual contribution
- Lead four engineers working on the modelling platform and surrounding systems; help the team deliver high-quality solutions
- Raise engineering standards across modelling systems and infrastructure, with a focus on reliability, observability, reproducibility, and safe change
- Set technical direction by understanding adjacent systems, workflows, and constraints to identify the right problems to solve at the right time
- Stay hands-on in the codebase, especially when the team is dealing with ambiguity, cross-system complexity, or problems without an obvious owner
- Lead by example in how problems are approached and how rigour is balanced with speed of delivery
- Contribute directly to the systems that matter most, making pragmatic changes that reduce friction, strengthen the platform, and improve reliability in production
- Engineering decisions in this area directly affect the accuracy of our credit decisions and the volume of lending iwoca can responsibly support
- Better infrastructure leads to faster experimentation and better models
- Help the team to work faster and with more confidence in the platform. Work with data scientists and strategy analysts to maintain the feedback loop between analysis, strategy and engineering

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.

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.

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
