Which team will you be joining?
The merchant experience is only as good as the platform behind it.
In the Account Experience team we build and own the full platform that 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 covers Primer Companion, Merchant Account Setup, Monitors, Workflows, Auditing, and the cross-cutting platform concerns that keep the merchant experience cohesive and consistent.
What will you be doing?
Own frontend projects end-to-end - from scoping through to production - across Acceptance's payment surfaces, checkout components, and merchant-facing tooling.
Lead architectural decisions on the frontend systems you work on, contributing to design sessions and producing RFCs and ADRs with minimal reliance on more senior engineers.
Build UI that is composable, performant, and adaptable.
Monitor the impact of your work in production, use metrics and dashboards to catch issues proactively, and take full ownership when things need to be fixed.
Hold a high quality bar for your own code and raise concerns when you see things in the codebase that don't meet it.
Contribute to incident response when it matters - taking the lead, driving to resolution, and keeping stakeholders informed throughout.
Share knowledge actively and help raise the quality and confidence of the engineers around you.
What we'd love to see
Solid frontend engineering experience, with a track record of independently delivering production-grade work across the full lifecycle.
Extensive experience with Typescript and ideally web components.
Comfortable taking on a project, scoping it, planning the architecture, and seeing it through without needing to be directed at each stage.
Strong understanding of how to build accessible, performant, maintainable UI at scale - ideally in a context where quality directly affects end users or downstream integrations.
Able to contribute meaningfully to architecture discussions and articulate trade-offs clearly.
Writes clean, well-tested code that peers would consider high quality - and holds yourself to that standard consistently.
Understands the user and business context behind the work, not just the technical brief.
Communicates clearly and directly, especially in async-first environments.

What's the culture like at Primer?
We're building a culture where people can do their best work and be proud of the impact they have. You'll be working with people who are mission-driven, smart, and reflective, and who are genuinely invested in building exceptional products and delivering success for our merchants.
We work remotely, and have done since day one. We believe that building a successful, profitable company goes beyond proximity. We invest in our relationships through great remote working practices and thoughtfully designed face-to-face time, including workations, our annual company retreat, and access to co-working spaces across most major cities.
The work is challenging. Scaleups are a challenge, and building category-defining products is a challenge. But there's a meaningful difference between a challenge and a struggle. At Primer, the right challenge comes with the right support: strong onboarding, a collaborative environment, and a team that is genuinely invested in your success. It's never something you face alone.
