About Taxd
Taxd is a UK tax filing platform trusted by thousands of customers, HMRC-recognised, ISO 27001 certified, and rated 4.9 stars on Trustpilot. Making Tax Digital is now mandatory for landlords earning over £50,000 and expands to millions more in April 2027. We've built the MTD service. It's live and HMRC-approved. Now we need someone to own it.
The Role
You'll take technical ownership of our MTD product, a TypeScript service deliberately decoupled from our legacy monolith. The architecture is sound, but it needs a permanent owner to stabilise it, ship outstanding features, and architect the next phase ahead of April 2027.
This is not a greenfield build. You'll inherit a working system with real users, live HMRC integrations, and documented debt. We need someone who reads the documentation before changing things and makes pragmatic calls about what to fix, what to leave, and what to rebuild.
What We're Looking For
* Strong TypeScript: comfortable improving types, generics, and middleware patterns, not just consuming them
* Backend experience in Node.js or comparable runtime
* Experience integrating third-party APIs with strict compliance requirements
* Able to design for complex state: partial failures, retries, idempotency
* Comfortable with AWS
* Pragmatic about technical debt
Nice to have: lightweight framework experience (Fastify, Elysia or similar), runtime validation libraries, HMRC or fintech/regtech background.
What We Offer
* £60,000 - £70,000 base + 10%+ bonus + equity
* 28 days holiday + birthday off
* Private medical insurance
* London Office (optional/hybrid)
* Real ownership in a small, high-trust team
To Apply
* Send a 2-minute Loom video explaining why you're the right person for this role. Applications without a video won't be reviewed. No agencies please.
