About Rec

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.

Booking a tennis court? Signing your kid up for swim lessons? Trying to find an open rec league? It shouldn’t feel like filing your taxes. We're partnering with parks & rec departments, golf courses, campgrounds, gyms and more to transform a $105B industry stuck in the Stone Age.

We’re not just putting recreation online—we’re redesigning it from the ground up, for the mobile-first, AI-powered world we live in.

And about AI? From simplifying registration flows to auto-scheduling entire recreation departments to empowering parks & rec staff to utilize the data to make their programming better, we use AI where it makes a real impact. We’re builders at heart, using the best tools to solve real problems for real communities.

If you get fired up by making tech that actually matters—to families, coaches, and kids all over the country—come join us.

Who We Are

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 and more. Now we’re channeling all that energy into something fresh—and fun.

We care about how we build, not just what. Our culture is fast, focused, and full of pride. We keep our standards high, our egos low, and our Slack memes spicy.

Our Values:

  • Be Relentless. Move fast. Own it. Ship real value early and often.

  • Win Together. Speak up, 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. This is a chance to help build the future of Rec from the ground up—product, platform, and culture.

As one of our earliest engineers, you’ll own high-impact pieces of our stack—from the beautiful modern consumer side, to tooling for local instructors and coaches to enable more learning, to the behind-the-scenes systems that keep parks humming.

You’ll make architectural decisions, influence the roadmap, and help us scale from thousands to millions of users.

What You'll Do

  • Partner closely with Engineering, Product, Design, and Customer Success to shape strategy and drive products from idea to launch—and beyond.

  • Build and maintain the core platform powering everything from booking experiences to staff tools to municipal dashboards.

  • Write clean, maintainable code and elevate the bar through thoughtful reviews and technical mentorship.

  • Invest in the foundation—making smart, forward-thinking decisions that keep our platform nimble and scalable.

What We're Looking For

  • 5+ years of experience building software in collaborative environments.

  • You work like a partner, not just a coder—thinking end-to-end alongside Product and Design.

  • You ship. Fast. Clean. Proud. You take initiative, and you finish strong.

  • You thrive in early-stage chaos and know how to bring order without over-engineering.

  • You communicate clearly, candidly, and constructively.

  • You’ve got strong opinions, loosely held—and a bias toward what works.

  • You’re not afraid of the grind. We hustle hard, because the opportunity is huge. We also ski, hike, and get outside—we’re building for recreation, after all.

Our Stack

  • Frontend: React, Next.js, TailwindCSS, Storybook

  • Backend: Node, Koa, Postgres, Objection.js

  • Infra & Ops: Inngest, Segment, Customer.io

Pay & Benefits

  • Compensation: $140,000–$200,000 base + meaningful equity (final offer will be based on your background, experience and skillset)

  • Benefits: Flexible PTO, top-tier health/dental/vision, and a 401(k) plan to support your future.

  • Work location: We are focused on hiring a team that will join us at our downtown San Francisco office.
