Software Engineer III, Frontend - Account Experience

📋 Description

• • 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.
• • 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.
• • 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.
• • ✅ A TYPICAL INTERVIEW PROCESS
• • An initial intro call with a Talent Partner
• • An interview with the Hiring Manager
• • Challenge Stage - Contextualised to the role

• • 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.
