The role
This company is building an API-first platform for global tax automation. Think sales tax, VAT, GST compliance for enterprises, all delivered through a world-class API. It's a complex, critical problem, and engineering sits at the absolute center of the business. They're backed by leading VCs, with significant Series B funding.
This is a Principal-level seat. You'll join a lean team that owns customer problems end-to-end, not just features. You'll co-own the roadmap with product, taking architecture, tooling, coding, testing, deployment, and operations from ideation to iteration. This isn't a role where you just execute; you're expected to set the technical bar, not follow it.

Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
