Primer.io - Senior DevEx Engineer

• Strong cloud infrastructure experience. AWS is preferred; we'll also consider strong GCP backgrounds. • Infrastructure-as-code as a working tool, not a buzzword. Terraform is preferred, but Pulumi, CloudFormation, Ansible or similar are fine. Not having Terraform specifically is not a blocker. • CI/CD as a core competency. You've owned the build, test and deploy workflow and preview environments, not just used them. • A history of measuring and improving delivery, using DORA, SPACE or a similar framework to back the work up. • Comfortable owning production systems and being part of an on-call rotation. • A genuine software engineering background. You've built and maintained applications or products, not just infrastructure tooling. • You can reason about what makes code pleasant to work with. This is what lets you build AI and developer tooling that engineers actually want to use. • An async-first communicator who works well in a remote, distributed team. • Hands-on experience building with AI or agent tooling, or working directly with LLM-based development workflows. This field is new, so real curiosity counts alongside real experience. • Familiarity with MCP servers and agent integration patterns. • Payments, fintech or other regulated-industry experience. • You may not like it here • We're remote-first and async-first. Nobody is looking over your shoulder, and nobody is going to hand you tightly scoped tasks. You own your work from problem to production. • This role carries real operational weight. You're on call for what you build, and when something breaks at an awkward hour, that's yours too. • The AI-enablement side of this is genuinely undefined. There's no playbook yet. If you want a clear, settled remit, this isn't it. If you want to write one, it is. • Pace and ambiguity are constant. Priorities shift as we learn, and you'll often be making calls without complete information. • ✅ 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.
