Backend Engineer - Acquisition Tech - DE
Hybrid in London or remote within the UK
We’re looking for a Backend Engineer
You’ll be the first engineer on the German side of Acquisition Tech, owning the customer acquisition systems that decide which small businesses iwoca reaches and how they convert.
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 Acquisition Tech team owns how iwoca reaches German small businesses – across paid advertising, SEO, social media, direct mail, and outbound sales – and how they become customers. The data and models behind every channel sit with the team.
You’ll report to the engineering lead for iwoca’s German market, based in London alongside the rest of the technical team. Day to day you’ll work with a product manager and a data scientist in London, plus commercial strategy, marketing, and sales – some of whom sit in Germany.
You’ll be the only engineer on the German side of acquisition, working in iwoca’s UK Acquisition Tech team’s codebase. You’ll work with their engineers on code reviews and design decisions.
The role
You’ll build the backend behind iwoca’s German acquisition technology – building on what already runs in the UK, and creating what Germany needs of its own.
- Ownership. You’ll own the German side of the acquisition stack – from the lead-value signals iwoca sends to ad platforms, to the bidding and attribution built on them – and decide what to build from scratch.
- Technical strategy. You’ll help shape the long-term roadmap. The team sets commercial objectives; you’ll shape the architecture, scaling, and technical direction.
- Funnel optimisation. You’ll work with marketing and data science to target relevant businesses across paid search, direct mail, and outbound sales, and to convert more of them once they arrive. You’ll integrate third-party APIs to minimise friction in sign-up and improve the lead data behind every channel.
