We’re Capital on Tap 👋
💳 Capital on Tap started because small businesses were underserved. Big banks were slow, their products weren't fit for purpose, and small business owners often couldn't access what they needed. We set out to fix that.
Today we're a financial platform - not just a credit card company. We offer a best-in-class business credit card, SME-focused spend management platform, a savings product that hit £1 billion in funds within its first year, and a growing suite of tools and financial products that make running a small business easier.
1,000+ employees, £20bn in annual card spend, 200,000+ customers, 17,000+ Trustpilot reviews averaging 4.7 stars, and we're profitable. We’ve done a pretty good job so far, but we’re just getting started!
🏡🏢This is a Hybrid role, the AI team work from our Moorgate (London) Offices 2 days per week.
AI Product Engineering at Capital on Tap
We are a small but highly empowered team with the overall goal of enabling the Engineering and Product teams to effectively use AI to deliver high-quality products and services faster to better serve our customers. Our responsibilities include improving speed of engineering delivery, making AI tooling and skills easily and widely available to the entire business, creating agents to perform tasks across a wide range of functions, and general oversight of engineering AI initiatives.
What you will be doing
This is a software engineering role first and foremost, with a focus on agentic systems, agentic orchestration and supporting technical teams in using AI
This is the type of work you will be doing:
- Developing agentic systems and orchestration layers to help us ship faster.
- Building “AI on Tap”, Capital on Tap’s internal AI enablement hub. It is the single place to see every AI agent the company runs, the cost of each one, how ready each codebase is for AI-assisted development, and how to get more value from Claude and other providers.
- Working with QA and Platform to integrate agentic testing and verification tools across our pipeline to deploy faster
- Owning build-vs-buy recommendations, from evaluation through to team buy-in
- Whatever it takes to reach an agentic future — tech debt, CI/CD, the unglamorous work that unblocks everything else
We’re Looking For 🔎
Required skills:
- Hands-on experience in C#, .NET
- Good testing practices, in both Unit and Integration testing
- Experience building agentic systems
- Experience in driving initiatives across engineering teams
