About the Business

This is a high-growth, UK-based artificial intelligence startup building a B2B SaaS platform for general practice accountants - designed to transform how firms manage compliance and unlock tax opportunities.

The platform helps accountants:

Detect tax compliance issues before HMRC submission.

Identify valuable tax planning opportunities that might otherwise be missed.

In a recent pilot, the product uncovered £3.6 million in tax relief across just 5,486 clients. With over 1,100 accountants on the waitlist, recent pre-seed funding secured, and an ambitious scale-up plan, this is a unique opportunity to get in early and shape something extraordinary.

Why This Role?

You'll operate at the intersection of AI, structured tax knowledge, and expert reasoning, helping to build a product that feels like having a CTA on the team 24/7/365.
