Senior Back End Engineer
Senior Back End Engineer - Insurance: New Ventures
Hybrid in London
We’re looking for a Senior Back End Engineer to help build iwoca’s new SME insurance venture from scratch. You’ll design integrations with insurance partners, leverage rich customer data, and create seamless experiences that turn data into action.
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
iwoca is expanding beyond lending into new product lines — and SME insurance is the first step on this journey. We’ve recently set up a dedicated Insurance Venture team to build and launch this proposition from the ground up. Operating as an autonomous unit and reporting directly to iwoca’s CEO, the team is small, fast-moving, and focused on delivering impact.
You’ll join a highly entrepreneurial environment and work closely with the Venture Lead, alongside specialists in data, marketing, and design — as well as with iwoca’s wider tech and analytics teams when needed.
The role
We’re looking for a self-starting Senior Back End Engineer to help design and build the technical foundation of our SME insurance business. This is a hands-on role focused on shipping early iterations fast while laying the groundwork for long-term scalability.
You’ll be responsible for:
Building robust and scalable services that power our insurance proposition end to end
Designing and implementing integrations with third-party insurance APIs (brokers, MGAs, carriers) to generate and process high-intent leads
Leveraging iwoca’s sophisticated customer data models to pre-fill insurance journeys, intelligently route customer traffic, and improve conversion
Collaborating closely with the Venture Lead, data scientists, and marketing to rapidly iterate and optimise based on early customer insights
Helping define the technical architecture and infrastructure for the venture, in collaboration with iwoca’s core engineering teams
Contributing to code quality, documentation, and best practices from the outset
This is a unique opportunity to be part of a new business from day one, with the backing of an established fintech and the freedom to build things right.
Example projects you might work on in your first 6–12 months:
Designing and building our lead routing infrastructure, connecting iwoca’s customer data to multiple insurance partners via API to deliver high-quality, intent-rich leads
Developing a modular integration layer to support connections with third-party insurers, with a focus on speed, resilience, and extensibility
Operationalising customer data for insurance by surfacing relevant attributes (business type, risk profile, trading behaviour, etc.) to pre-fill journeys and improve partner matching
Working with data analytics to score and prioritise leads, enabling more efficient routing and higher conversion rates
Collaborating with marketing to test and iterate customer acquisition flows, including pricing experiments, channel-specific landing pages, and campaign tracking infrastructure
Creating the backend for a dynamic insurance needs assessment tool that guides SMEs toward the right insurance products
Building the foundation for longer-term capabilities, such as embedded quote journeys, policy management tooling, and real-time feedback loops with partners
The requirements
Essential:
Experience in back end engineering, ideally with Python.
Ability to manage projects end-to-end; understanding a business problem, designing and executing a solution, and communicating with stakeholders.
Bonus:
An understanding of data analysis and statistics.
A strong numerical or technical background, underpinned by a degree in maths, physics, computer science, engineering, or a related field.
Experience with Django.
Experience with relational databases (ideally PostgreSQL).
The salary
We expect to pay from £75,000 - £95,000 for this role. But, we’re open-minded, so definitely include your salary goals with your application. We routinely benchmark salaries against market rates, and run quarterly salary and performance reviews.
