## About the Role

* Proven experience scaling and operating large-scale microservices in production.
 * Fluency in multiple languages across the stack (e.g., Node.js/TypeScript, Go, ReactJS).
 * A strong sense of end-to-end ownership: from architecture to operations, testing to delivery.
 * A builder's mindset, shipping fast and iteratively, using data to drive decisions.
 * Full professional proficiency in written and spoken English.

## Description

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.

The work

 * Design, build, and operate critical REST APIs that power global tax compliance for enterprise customers.
 * Own features across the full stack, from backend business logic to customer-facing interfaces.
 * Take products through their entire lifecycle: ideation, delivery, support, and continuous iteration.
 * Scale and operate large-scale microservices in a high-growth, API-first environment.
