Staff Engineer responsible for solving complex technical problems spanning multiple engineering groups, product pillars, platforms, or ecosystems. Leads cross-group projects from design through production, contributes hands-on code, owns technical roadmaps, scales systems, resolves broad technical decisions, and coaches senior engineers. The role requires deep distributed-systems and API-design expertise, strong communication, and the ability to influence without direct authority.

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 Engineering team work from our London (Moorgate) Offices 2 days per week.

This is a multiple headcount role, so please don't be put off if you've seen this advertised for a while.

The role

Staff Engineers take on technical problems that no single engineering group can solve on its own. Your remit is a product pillar, a platform or a global ecosystem. You'll work across the groups in it, design the solution, contribute to the hardest parts yourself and get several teams moving together.

What you'll be doing

  • Lead cross-group projects from first design to production, including when they go wrong.
  • Plan ahead, so your systems can handle around ten times today's load without a rewrite.
  • Stay hands-on. Write production code, review designs and build the hard parts yourself.
  • Own the shared technical roadmap for your area.
  • When a decision spans several groups, bring them together, weigh the options and own the outcome.
  • Coach Lead and Senior Engineers, and help with senior hiring and promotions.

What success looks like

  • Faster delivery, decisions made swiftly, alignment with the direction set by the Engineering Architecture Team, fewer incidents and less duplicated work in the groups you support. 
  • A Staff Engineer helps several groups decide well, while owning the outcome of the decisions that have a broad impact.
  • You'll agree named outcomes with your manager each quarter.

What we're looking for

  • A track record of leading technical work across teams
  • Deep experience with complex distributed systems and API design, and the judgement to pick the boring solution when it's the right one.
  • Hands-on experience with .NET or a similar back-end stack. Familiarity with web or mobile frameworks would also be beneficial but not required.
  • Exceptional communication and collaboration skills with engineers and non-technical people alike.
  • Demonstrable ability (and comfort) to influence people who don't report to you.

Nice to have: fintech or regulated financial services experience, and experience using AI tools to make engineering teams better.
