Head of Engineering

You run engineering day to day: delivery, reliability, and the technical bar of everything we ship.

Rebill processes real money across six markets on its own infrastructure. Event-driven microservices on a message bus, Kubernetes across Azure and AWS, infrastructure as code, and smart routing across a different set of local acquirers in every country. Card data lives in an isolated, tokenized environment.

We are AI-native by design. You will push engineering beyond AI-assisted coding into agentic workflows: autonomous coding and review agents, evals, feedback loops, human-in-the-loop controls, observability, and guardrails that let us safely automate more of the SDLC and production operations. The goal is not to use AI more; it is to rethink how a small engineering team can build and operate financial infrastructure.

You will hire and co-lead a small, high-caliber in-house engineering team alongside the CTO, while managing external engineering partners.

This is a hands-on seat. You review pull requests, write code, automate aggressively, and stay close to production. You are intellectually curious and passionate about documenting and sharing what you learn, inside Rebill and with the broader engineering community.
