About the role

Key responsibilities & impact

Own delivery end to end across Partner Experience and Integrations Core, holding both sub-teams to a consistent bar on quality and pace without becoming the bottleneck yourself.
Lead, coach, and grow the engineers on your team: career development, feedback, performance, and building an environment where strong people do their best work.
Stay technically credible. You'll review design decisions on the Nexus framework and the wider integration platform, evaluate trade-offs on scalability and maintainability, and tell when a design doesn't hold up.
Treat external developers as first-class users. Much of what your team ships is public surface area, so you'll push for stable contracts, clear documentation, and changes that don't break the partners building on you.
Partner with Product to shape a realistic roadmap across a broad surface, surface risks early, and protect the team from over-commitment.
Drive operational excellence: monitoring, incident response, and post-mortems that genuinely close out their follow-ups, on systems that partners depend on.
Hire. As Primer scales through its Series C plan, building and calibrating a strong team across both sub-teams is a core part of the job, not a side task.

Requirements

What you’ll need

Experience managing a team of software engineers, with real accountability for their delivery, growth, and performance, not just coordination.
Enough technical depth to be respected by strong engineers: you can interrogate a system design, spot the wrong trade-off, and recognise when the information you've been given doesn't add up.
A background building and operating platform, API, or integration-heavy systems, ideally ones consumed by developers outside your own company.
Comfort operating with high autonomy and little process: you resolve ambiguity rather than wait for it to be removed.
The judgement to know when a change is significant enough to pull in Staff Engineers or trigger a design review, and the credibility to hold that line.
Nice to have:
Experience with developer platforms, marketplaces, or ecosystem products where third parties build on what you ship.
Exposure to payments, fintech, or other complex infrastructure domains, though depth of engineering leadership matters more than the specific industry.
