An Introduction to Primer
Primer is the unified infrastructure for global payments. We give finance and payments teams the visibility and control to reduce complexity, improve performance, and capture more revenue - all from a single platform.
Which team will you be joining?
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.
What will you be doing?
- Setting and driving front-end technical strategy across the Account Experience teams, from architecture and component-system decisions through to hands-on implementation where it counts
- Owning the architecture of a complex, data-dense merchant platform — the patterns, state management, and performance characteristics that hold up as the surface area grows
- Shaping how Primer AI Companion matures as a first-class merchant interface, including the front-end architecture that makes a conversational surface feel native to the platform
- Holding the experience coherent across Account Setup, Monitors, Workflows, and Auditing — building the shared component and design-system foundations that stop the areas drifting apart
- Leading engineers across teams without direct authority, through code, design reviews, and technical mentorship that raises the front-end bar around you
- Owning the things that are easy to neglect: accessibility, performance budgets, and front-end observability as first-class concerns, not afterthoughts
- Partnering with Product and Design, and with backend engineers across teams, to shape decisions where front-end constraints or opportunities are material
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.

What We're Looking For
- Demonstrable experience operating at staff or principal level: setting front-end technical direction across multiple teams, not just within one
- Deep front-end engineering expertise with TypeScript and React, and a track record of architecting complex, long-lived web applications
- Real fluency in the things that separate good front-end from great: state management at scale, performance, accessibility, and component-system design
- The kind of judgment that earns trust fast — engineers follow your technical lead because you're right, not because of your title
- Enough comfort across the stack to reason about the APIs and services your front-end depends on, and to partner with backend engineers as an equal
- Strong written and verbal communication, including making complex technical decisions legible to Product, Design, and non-technical stakeholders
- Comfort working in payments, fintech, or platform contexts is welcome, though depth of engineering matters more than the specific industry.
