AI Engineering at Capital on Tap

We’re building a small team of ~3 AI-specialist software engineers who embed directly within product teams to deliver intelligent features. Rather than operating as a separate unit, you’ll work alongside existing teams as an internal consultant, helping them deliver AI-powered capabilities whilst building their skills through hands‑on collaboration and structured training. Part of the role has a hand in upskilling the wider Engineering department through workshops, documentation, and knowledge transfer.

  • From the first line of code to production, monitoring, and continuous improvement – you ’ l l own the SDLC
  • Teamwork makes the dream work – you ’ l l partner with Product Managers, QA ’ s , and fellow Software Engineers
  • You ’ l l build bulletproof unit and integration tests to keep our software sharp and our users happy
  • Bugs happen. When they do, you ’ l l be ready to troubleshoot and tweak as needed
  • You ’ l l bridge the gap between tech speak and business goals, ensuring everyone ’ s on the same page and moving forward together

We ’ r e Looking For

  • 4+ years hands‑on experience in C#, .NET Core
  • Good testing practices, in both Unit and Integration testing
  • Good understanding of database technologies
  • Experience in using Agile development practices
  • A passion for learning new skills and technologies
  • A proactive, supportive, and collaborative team player

Nice to have

  • Experience sharing knowledge through training sessions or workshops, helping other teams get the most out of tools or systems you’ve built.
  • Practical experience building backend applications or service wrappers that integrate with AI APIs or LLMs

Diversity & Inclusion
