Which team will you be joining?

In the Orchestration team we build the engine that powers intelligent, seamless, and reliable payments - across any provider, method, or market. We own the full orchestration layer: routing decisions, fallback logic, and the smart infrastructure that makes every payment perform at its best.

This team covers everything from checkout and payment processing through to tokenization, authentication, fallback logic, developer tooling, and workflows.

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 - payment experiences that merchants can configure and extend to fit their own products.

* 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.

Nice to have:

* Experience building SDKs, embeddable components, or developer-facing tooling.

* Familiarity with payments, checkout flows, or high-availability frontend systems.

You may not like it here if:

* You enjoy working in an office-setting, we are remote-first and always will be!

* You are not comfortable with shifting context and navigating ambiguity

A typical interview process

* An initial intro call with a Talent Partner

* An interview with the Hiring Manager

* Challenge Stage - Contextualised to the role

* A final, values-alignment interview

What's the culture like at Primer?

We're building a culture where people can come and do their best work and enjoy it. We want our people to be proud of the impact that they have at Primer, and of the work that they are doing. You will be working with a team of people who are mission-driven, smart, and reflective, and who are invested in building exceptional products and delivering success for our merchants (and we also know how to have fun along the way).

We work remotely. We believe that building a successful, profitable company goes beyond proximity. We invest in our relationships with each other through great remote working practices and thoughtfully designed face-to-face time together. Our heads-together time comes in…
