Ambrook, a Series A startup backed by Thrive Capital, Dylan Field, and Homebrew, is rebuilding financial infrastructure for American family-run businesses. We are seeking a Platform Engineer to help build the foundational systems that power the rest of the company. This role spans product infrastructure (PostgreSQL databases, GCP environment) and company infrastructure (internal tooling, data platforms, and the systems behind internal AI workflows). Our stack is primarily TypeScript, with some GCP scripting learned on the job. The role blends strong infrastructure judgment with a product mindset, collaborating with engineers and non-engineering teams to uphold quality, security, and scalability as Ambrook grows. You’ll help build the infrastructure behind Ambrook’s agentic systems, focusing on shared frameworks, evals, harnesses, sandboxes, and interfaces that let internal teams and customer-facing product teams deploy and operate agents with confidence. We envision a world where any team can request an agent, deploy it to the cloud, run evals, and see results on a dashboard. Your work will improve the experience of every employee and expand what the whole company can ship.

Within 1 month you’ll: build a mental model of Ambrook’s product and infrastructure (PostgreSQL, GCP, data systems, developer tooling, security foundations, and emerging agent infrastructure); build relationships with engineering and non-engineering stakeholders; ship a meaningful infrastructure improvement to production; identify and prioritize platform opportunities. Within 3 months you’ll: own a plat
