An Introduction to Primer
Primer is the unified infrastructure for global payments. We give finance and payments teams the visibility and control to reduce
complexity, improve performance, and capture more revenue - all from a single platform.
Backed by Sofina, Peak XV Partners, ICONIQ, Tencent, Accel, and Balderton, we're building the payments layer the world's best
companies rely on.

WHICH TEAM WILL YOU BE JOINING?
You'll join Infrastructure, the team that owns the platform every other Primer engineer builds and ships on. CI/CD, deployment,
internal tooling, ephemeral environments: if it's how code gets from a laptop to production safely, it's ours.
We operate the way the rest of Primer does. Remote-first, async, high autonomy, low bureaucracy. You build it, you own it, and
that includes running it in production. You'll report to the Engineering Manager for Infrastructure & Data and work alongside a
small group of senior infrastructure engineers.
What makes this interesting right now is the human-AI development loop. Coding agents are changing how software gets built, and we
want someone to own how that actually works at Primer rather than bolting it on. That part of the role is yours to define.
WHAT WILL YOU BE DOING?
- Own Primer's internal developer platform end to end: the CI/CD pipelines, deployment workflows (canary, blue/green),
self-service tooling and ephemeral environments that every engineer here depends on to ship.
- Build the human-AI development loop. This is the most open part of the role: the tooling and automation that let engineers work
effectively alongside coding agents, and the patterns that make agent-driven workflows fast and safe at Primer.
- Treat developer productivity as a measurable system. Instrument it, find where delivery actually slows down, and ship the
changes that fix it instead of guessing.
- Take real operational ownership. You'll join the Core Infrastructure on-call rotation and own the reliability of what you
build.
- Set the technical direction for how Primer's engineers build and ship, and bring less experienced engineers along with you as
you do it.
- Improve how engineers write code, not just how they ship it. Partner with product teams to make the tools, frameworks and
internal APIs they use everyday more ergonomic, and help reduce the friction of building features at Primer.
- Build Primers paved roads. Reduce the application boilerplate engineers write, shape standards around how services are built
and configured, and own the golden-path tooling that lifts efficiency across every team.
- Work in the open across a fully distributed team, making your decisions and trade-offs visible rather than holding them in your
head.
WHAT WE'RE LOOKING FOR
- Strong cloud infrastructure experience. AWS is preferred; we'll also consider strong GCP backgrounds.
- Hands-on Kubernetes experience.
- 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.
Nice to have:
- 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

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

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.
