Chief Tax Officer - Join a Game-Changing AI Startup
Remote-first (Quarterly paid travel to London or York) Full-Time | Leadership Role Sector: AI, Tax Technology, SaaS
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?
We're hiring an experienced and strategic Chief Tax Officer to lead the Tax Knowledge function - a critical pillar in the business. This is not your traditional in-house compliance 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.
This is an exciting chance to code tax knowledge into logic that drives powerful software.
What You'll Be Doing
Design and Maintain Tax Knowledge Structures
* Create and manage detailed tax ontologies, classifications, and knowledge bases.
Develop Rule-Based Reasoning Systems
* Build systems that simulate expert decision-making and automate tax logic - The Tech team will be working with you on this!
Collaborate with Tax Experts
* Work alongside subject matter experts to validate and refine rules and structured knowledge.
Keep Logic Current and Legally Accurate
* Maintain alignment with evolving legislation, HMRC guidance, and legal precedents.
Contribute to Platform Architecture
* Help shape the design of scalable, transparent knowledge systems for long-term growth.
What We're Looking For
* Strong UK tax experience (likely CTA-qualified or equivalent)
* Deep understanding of corporate tax, compliance, and advisory logic
* Systems-focused mindset - excited by structure, automation, and AI
* Collaborative and curious - enjoys solving complex challenges with others
* Ready to step away from "traditional" roles and build something new
What's in it for You?
* Opportunity to work at the cutting edge of AI + tax
* Remote-first working with quarterly meetups (London/York - travel paid)
* Autonomy and ownership in an early-stage tech business
* Work that's meaningful and future-focused
* Join a funded, ambitious team with huge growth potential
