Senior Software Engineer (Developer Experience)

Rec Technologies•San Francisco, CA

1d•$140,000 - $200,000•Onsite

About The Position

At Rec (rec.us), we're reimagining how the world plays, trains, competes, explores, and gets outside. Our mission is to empower the entire recreation community to thrive, and our vision is bold: power recreation worldwide. We're partnering with parks and rec departments, golf courses, campgrounds, gyms, and more to transform a $105B industry stuck in the Stone Age. We're redesigning recreation from the ground up for the mobile-first, AI-powered world we live in. We're builders at heart, using the best tools to solve real problems for real communities. We're a small team with outsized ambition. We've built products and led teams at places like Google, Amazon, Uber Eats, MasterClass, The Athletic, Nextdoor, and more. Now we're channeling all that energy into something fresh and fun. Our Values: Be Relentless. Move fast. Own it. Ship real value early and often. Win Together. Speak up and go beyond the boundaries of your role. That's how we win. Take Pride. Treat this like it's yours, because it is. About The Role This is not a seat-filling role. We're a Series A company in scaling mode, shipping more code every week, and the systems that let us ship quickly and confidently need someone who owns them. That's this role. You'll own the tools, workflows, and guardrails that let every engineer at Rec move fast without breaking things. CI/CD pipelines, automated testing, end-to-end test coverage, local development environments, data snapshots, package upgrades, the infrastructure of engineering itself. When we ship a regression, it's your systems that should have caught it. When onboarding a new engineer takes a day instead of a week, it's your work that made the difference. You'll work closely with our Infrastructure engineer on the foundation, and with every product engineer on the team to understand where the friction lives and how to remove it. You'll still contribute to product code when the work crosses into your domain, but the primary job is making the whole engineering org faster and more reliable.

Requirements

5+ years of experience building software in collaborative environments, with meaningful time spent on developer tooling, testing infrastructure, or CI/CD.
You're fired up by the mission.
AI fluency is non-negotiable.
Deep experience with CI/CD systems. You know what makes a pipeline fast, what makes it flaky, and how to tell the difference. You've debugged the weird cases.
You think about testing as a product. Test infrastructure is a deliverable, not an afterthought. You care about coverage, but you care more about whether the tests actually catch real bugs.
You reduce friction where others accept it. You notice the slow build, the flaky test, the painful local setup, the package that's three major versions behind. And you fix it.
You ship with quality.
You thrive in ambiguity.
You work like a partner, not just a coder.
You communicate clearly, candidly, and constructively.

Responsibilities

Own our CI/CD pipelines. Make builds fast, reliable, and easy to debug. Every minute saved compounds across the team.
Build out automated testing and end-to-end test coverage. Design the quality safeguards that catch regressions before they reach production.
Maintain and improve local development environments. New engineers should be productive on day one, and existing engineers shouldn't lose a morning to environment drift.
Manage data snapshots and seed data for local and staging environments. Realistic data makes realistic testing.
Drive package upgrades, dependency hygiene, and the unglamorous work that keeps the platform from rotting.
Partner with the Infrastructure engineer on the shared foundation, and with product engineers to understand where friction slows them down.
Use AI tools fluently to accelerate this work, from generating test coverage to automating upgrade PRs to analyzing CI flakiness. This role has real room to push what's possible with AI-assisted tooling.
Contribute to product code when the work touches developer experience.
