Senior Engineer, Fullstack - Growth

Strong, proven frontend expertise — production experience architecting and building complex frontend applications, not just consuming a design system

Comfortable being the most senior frontend voice in the room, including pushing back on design or product where the frontend reality demands it

Some backend experience and a genuine willingness to work in a Python codebase — depth isn't required, but you shouldn't be reluctant to touch it

Experience mentoring other engineers, ideally including people earlier in their career than you

Nice to have, not required:

Experience building or integrating payment products

Experience in a growth, onboarding, or activation-focused product surface

The team is still forming, so you're inheriting mentoring responsibility for people who haven't been hired yet — the "who" of who you're mentoring is still unknown

Remote-first, high autonomy, no hand-holding — you're expected to set your own standards, not follow someone else's playbook

Early-stage team means some ambiguity on process and tooling that a more established team would already have solved

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.
