Who you are

- Advanced proficiency in software development using an object-oriented language
- Business-orientation: you can collaborate with stakeholders to translate complex challenges into scalable solutions. You have owned technical systems that deliver business outcomes in fast-paced environments
- Demonstrable leadership skills: you have mentored juniors and inspired teams to deliver cross-functional projects. You can balance hands-on coding with strategic planning
- Experience building and shaping large systems in complex business domains
Desirable
- Experience with Python, Django or PostgreSQL
- Familiarity with data analytics and Machine Learning processes
- An understanding of complex data systems, including event-sourced data models
- A strong numerical or technical background, ideally with a degree in maths, physics, computer science, engineering, or a related field

What the job involves
- Lead the evolution of our decision-making and offers-generating systems and architecture. You'll build and improve critical systems, shape iwoca’s technical vision, and collaborate with cross-functional teams to deliver innovative, data-driven solutions
- You’ll help iwoca realise a long-term vision for a dynamic, data-driven document and offer strategy for existing customers.
- You’ll lead the design and development of systems that intelligently route existing customers to the most appropriate credit-assessment process, and the most appropriate offer terms based on their unique profile and needs.
- This means moving beyond static rules to build scalable, adaptive systems that integrate real-time data and business logic. Your work will be central to how we deliver the right product, to the right customer, at the right time - a capability that’s critical to iwoca’s future growth
- Re-architect the team’s code to meet an ambitious set of ever-changing challenges, though you’ll need to collaborate with principal engineers in other teams to design and deliver a coherent system as the system evolves to meet our long-term goals
- Conceive projects for the team to continuously improve aspects of various systems and processes
- Lead the evolution of our system architecture to optimise customer journeys and enhance decision-making and offer generation processes
- Build strong stakeholder relationships, mentor junior developers, and foster a culture of learning and innovation
- Share a clear technical vision that aligns with long-term goals while working closely with tech, product, and analytics teams
- Enjoy open communication and access to leadership without layers of bureaucracy
- Embrace the energy and adaptability of a startup, where decisions are made quickly, and every day brings new opportunities and challenges
- Collaborate with teams that use shared systems and infrastructure, with support from common resources like a DevOps team

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.

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
