Senior Software Engineer

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 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. From simplifying registration flows to auto-scheduling entire recreation departments to giving parks and rec staff the data to make better programming decisions, 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, Nextdoor, 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 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, adding new partners and users every day, and every engineer we hire shapes what Rec becomes.

As a senior engineer, you'll own meaningful surface area across our product. That might mean
facility management
(reservations, permitting, invoicing),
program management
(camps, classes, lessons, eligibility), or
payments and platform
(payments, financial transactions, accounting, reporting). Wherever you land, you'll work end to end, from consumer-facing booking flows, to staff tools for coaches and administrators, to the systems that keep parks humming behind the scenes.

You'll make architectural decisions, influence the roadmap, and help us build something the recreation industry has been waiting decades for.

What You'll Do

• Partner closely with Engineering, Product, Design, and Partner 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, reliable, maintainable code. Elevate the bar through thoughtful reviews and technical mentorship.
• Use AI tools fluently across your workflow, from scaffolding and code review to debugging production issues and analyzing data.
• Invest in the foundation. Make smart, forward-thinking decisions that keep our platform nimble and scalable as we grow.

What We're Looking For

- 5+ years of experience
building software in collaborative environments.
- 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.
- 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.
- Product judgment is part of the job.
You don't just follow orders. You think critically about what to build, what to defer, and what to push back on. You ask "should we?" before "how do we?"
- You thrive in ambiguity.
Early-stage problems are rarely well-defined. You bring order without over-engineering, and you know the difference between clarifying a spec and getting stuck on one.
- You work like a partner
, not just a coder. You think end-to-end alongside Product, Design, and Partner Success.
- You communicate clearly
, candidly, and constructively. Strong opinions, loosely held, with a bias toward what works.

Our Stack

- Frontend:
Next.js (hosted on Vercel), React, TypeScript
- Backend:
Node.js, Koa, Objection.js, PostgreSQL
- Infra & Ops:
AWS, Temporal, Twilio
- AI & Tooling:
AI proficiency is mandatory here, not optional. Every engineer uses AI tools daily, for code generation and review, for operational work via MCP servers and tool use, and for data analysis. We expect you to already be fluent with tools like Claude Code, Cursor, or equivalent, and to have strong judgment about when to lean on AI and when to override it.

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're building a team that works together in person at our downtown San Francisco office. If you're Bay Area-based, you'll be in the office most days, because that's where the momentum, collaboration, and magic really happen. But we're also human. Need remote days while traveling? Want to spend a week with family on the East Coast? Totally fine. We trust you to balance real life with real impact.

Ready to build something real? Something fun? Something big?

We’re ready for you.
