our culture >Which team will you be joining?The merchant experience is only as good as the platform behind it — and most of that experience is the interface itself. The Account Experience team builds and owns the full platform merchants use to interact with Primer — from initial setup through to day-to-day operations, and increasingly through Primer AI Companion as a first-class interface

The team spans several connected areas: Primer Companion, Merchant Account Setup, Monitors, Workflows, Auditing, and the cross-cutting concerns that keep the whole merchant experience cohesive.

 As Staff Engineer you'll set front-end technical direction across these areas, not within a single one.

You'll work across 2-3 teams, partner with multiple stakeholders, and stay hands-on in the implementation that matters most.

The team runs a 'you build it, you own it' model: engineers own their work from design through to production.

 The stack includes TypeScript, React, and modern front-end tooling, sitting on top of services in Python, AWS, Kubernetes, and Terraform.
