Senior Software Engineer (Developer Experience)

Rec Technologies•San Francisco, CA

1d•$140,000 - $200,000•Onsite

About The Position

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. We work hard because recreation matters to families, coaches, and kids across the country. We also ski, hike, and get outside. We're building for recreation, after all.
AI fluency is non-negotiable. You already use AI tools daily and have real judgment about when to trust them, when to verify, and when to override. If AI tools aren't yet core to how you work, this role will be a rough fit.
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. Fast, clean, and proud, but never careless. Every customer transaction matters to us: a missed swim lesson registration, a double-booked court, a failed payment. Reliability is the baseline.
You thrive in ambiguity. Developer experience work is rarely well-defined. You figure out what's actually worth doing, and you do it without over-engineering.
You work like a partner, not just a coder. You think end-to-end alongside the rest of Engineering, and you know that great DevEx work is a service to the whole team.
You communicate clearly, candidly, and constructively. Strong opinions, loosely held, with a bias toward what works.

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.
