Which team will you be joining?
We play a key role in helping merchants handle disputes and prevent fraud. The Protection team owns the risk management suite that surfaces these threats, and helps merchants build automation to handle them at scale.
What will you be doing?
Build the dispute dashboard from scratch - deadline visibility, evidence status, response tracking
Ship features end-to-end, with support from more senior engineers on scoping and architecture, across a lifecycle merchants are actively asking for
Turn fraud vendor comparisons (Riskified, Forter, Signifyd, Sift) into something merchants can actually see and act on, not just a backend integration
Own well-defined pieces of the native rules engine UI - surfacing velocity rules, blocklists, and fingerprinting signals in a way non-technical merchant teams can actually use
Deploy your own work to production and monitor its impact, with more experienced engineers close by when you need them
Work directly with Product and your EM on a small team where your features are visible
What we're looking for
Experience shipping production ready frontend features, with growing autonomy and less need for hand-holding on the basics
Solid grasp of API design fundamentals and how to build for performance as usage grows
Comfortable writing tests and thinking through edge cases and error handling
Genuine care about the details of what you ship
Nice to have, not required
Exposure to fraud, risk, disputes, or another operationally sensitive domain
Experience building dashboards or admin tooling from a blank slate
Comfortable working with APIs
Willingness to contribute to our Python backend when needed
What you should know
This team is new enough that some structure - on-call rotas, tooling, conventions, you'll be building it alongside doing the actual work
Real ambiguity in the early days: you will be the one deciding what "good" looks like before anyone else has an opinion
A handful of people today, so your individual output is highly visible
✅ 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 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.
