Senior Engineer - Growth (FE)

What you'll be doing:

• Lead frontend architecture and technical direction for self-serve onboarding and platform experience.
• Partner closely with Design to take onboarding from concept to production, shaping the details that decide whether a merchant's first steps feel effortless or frustrating.
• Mentor and raise the bar for engineers joining the team, setting frontend conventions and quality standards.

What we're looking for:

• Strong, proven frontend expertise with production experience architecting and building complex frontend applications.
• Comfortable being the most senior frontend voice, including pushing back on design or product where frontend reality demands it.
• Some backend experience in Python and a genuine willingness to work in it.

Culture at Primer:

• Remote-first, high autonomy, and no hand-holding — you're expected to set your own standards.
• Building a culture where people can do their best work and be proud of the impact they have.
• Invest in relationships through workations, company retreats, and co-working space access across major cities.
