The company

Imagine a world where every small business has the power to thrive. That's the world we're building at iwoca. Small businesses aren't just statistics – they're the heartbeat of our communities, the character of our high streets, and the engine of our economy. 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.

Our impact speaks for itself: we've provided billions in funding to over 150,000 businesses across Europe, making us one of the continent's leading fintech innovators. But we're just getting started. Our mission? To empower one million businesses with the financial tools they deserve.

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. Whether it's managing cash flow or seizing unexpected opportunities, we ensure businesses get the funds they need – often within minutes.

The team

Brokerages that work with iwoca refer customers to us in exchange for a commission. They’re our largest source of new business.

The Broker Tech team owns the full experience for brokers and their customers - from first contact to funded loan. We work closely with commercial and strategic stakeholders, so we value people who can think fast, adapt quickly, and spot opportunities for improvement.

You’ll be encouraged to bring your own ideas, take responsibility for what you build, and see it through - from design, to release, to ongoing impact.

The role

• Autonomy: Own projects from scoping and design to execution. Lead multi-engineer projects, coordinating with analysts, product managers, and other stakeholders.

• Impact: Enhance our offerings to meet the needs of repeat customers, improving their access to tailored lending solutions.

• Shaping Systems: Design and maintain robust, flexible, and maintainable systems to ensure scalability and fast-paced development.

• Learning Through Iteration: Embrace a culture of experimentation, using trial and error to uncover insights, refine approaches, and grow your technical and strategic skills.

• Continuous Deployment: Work iteratively, supported by high test coverage, and contribute to the team’s frequent deployment cycles (averaging more than once per day).

• Data-Driven Decision-Making: Use hypothesis testing and metrics such as issuance and profitability to quickly iterate and optimise our approach.

The projects

• Operational processes and workflow automation: Improve Broker Account Managers’ and Broker Relationship Managers’ efficiency through task automation, email strategy enhancements, and better resource management by improving communication systems, and task prioritisation.

• Extending features of our Introducer Portal: Upgrade the Introducer Portal to deliver tailored experiences for brokers and partners, with features aligned to their roles. Enhancements include new tools for brokers to track and manage loans more effectively, improving visibility, autonomy, and overall service experience.

• Extend our commission system: Enhancing how commission structures are assigned, managed, and tracked. Improvements include clearer commission ownership visibility within our CRM and a more flexible system for setting and interacting with commission rules, supporting better transparency and alignment across teams.

The requirements

Essential:

• Significant experience in back end engineering, ideally with Python.

• Ability to manage projects from beginning to end; understand a business problem, design and execute a solution, and communicate with stakeholders.
