Primer.io - Security Engineer

• Working experience in product or application security: you've done security reviews or threat modelling and can spot the risks that matter • The ability to read and write code, not just review it. You're comfortable building small tools and automation rather than only filing findings • Sound judgement about risk. You can weigh a real threat against a theoretical one and explain your reasoning clearly • The ability to plan and deliver your own work independently once you understand the direction, while knowing when to pull in the senior engineer • Clear communication with engineers who aren't security specialists, since most of your impact lands through their work • Exposure to compliance frameworks like SOC2 or PCI, or genuine appetite to learn them • Background in payments, fintech, or another regulated, high-stakes domain • Interest in areas like supply chain security, detection engineering, or AI security • You may not like it here • It's remote-first and high autonomy. You'll get direction, but nobody checks your progress daily. If you need close structure, this will be uncomfortable • You'll move between proactive project work and reactive BAU, and priorities will shift as audits and incidents land. Tolerating that change is part of the role. • ✅ 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 co-working space access worldwide. • 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.
