Back End Tech Lead - Funnel Platform

Back End Tech Lead - Funnel Platform Hybrid in London (UK) or Remote within the UK We’re hiring a Tech Lead for our Funnel Platform Team. You will lead the evolution of the shared code, frameworks, and integrations that power our services, build and improve business-critical systems, and shape the technical vision. Your customers are other iwoca engineers.

The company Small businesses move fast. Opportunities often don’t wait, and cash flow pressures can appear overnight. To keep going, and growing, SMEs need finance that’s as flexible and responsive as they are. That’s why we built iwoca. Our smart technology, data science and five-star customer service ensures business owners can act with the speed, confidence and control they need, exactly when it’s needed. We’ve already cleared the way for 100,000 businesses with more than £4 billion in funding. Our passionate team is driven to help even more SMEs succeed, through access to better finance and other services that make running a business easier. Our ultimate mission is to support one million SMEs in their defining moments, creating lasting impact for the communities and economies they drive.

The Team

The Platform team owns approximately 10 shared services that the rest of iwoca engineering builds on top of - including the frameworks and integrations with external data providers (Experian, Equifax, TransUnion, Companies House etc) that underpin our credit decisions. This is not an SRE or DevOps team. Funnel Platform is code and framework focused - building and stewarding the shared services that the rest of engineering depends on. The team works hand-in-hand with other teams to build and deliver a shared vision for the future of the platform.

The Role

The Tech Lead role combines individual contribution, line management, and ownership of the platform roadmap. You will lead a team of developers focused on the shared services and frameworks that other iwoca engineering teams build on, driving technical strategy and translating our long-term vision into robust, maintainable systems. Your mission is “Making Change Easy” for the engineering teams that depend on you by owning shared services and being the trusted reviewer for contributions from partner teams, ending conflicts between maintenance and delivery through dedicated ownership. This is a hands-on technical leadership role where you will take full ownership of the team’s roadmap and provide direct line management to its engineers. A balance of delivery, leadership, and influence: Act as a hands-on contributor and lead by example in quality, testing, and performance. Drive the technical strategy and execution for the Platform team, translating vision into well-designed, robust, and maintainable systems. Set direction without a PM - spot the problems worth solving, back them with data, and drive them to delivery. Architectural ownership and impact: Lead the development of shared frameworks and services that other engineering teams contribute to and build on. Collaborate with stakeholders in the commercial funnel teams to build a shared roadmap. Own the health of the shared services other teams depend on - spotting emerging issues, reviewing contributions from consuming teams, Shape architectural improvements to the shared services over time - measured on developer experience, service health, and reliability, not feature throughput Team leadership and management: Manage and mentor engineers, taking responsibility for their performance, coaching, and career development. Define and champion engineering best practices within your team and across the wider engineering group.

• Experience with Python, Django, or PostgreSQL.
• Familiarity with data analytics or machine learning processes.
