Full Stack Software Engineer

About CatchBack

CatchBack is building the next generation of collectibles commerce. We make buying, selling, and discovering collectibles more engaging through mystery packs, instant liquidity, marketplaces, and new ways for collectors to interact with their collections.

We're a fast-growing startup backed by YC, Foundation Capital, Coinbase Ventures, Robinhood Ventures, and several top angels— based in San Francisco, working at the intersection of collectibles, commerce, gaming, and technology.

The Role

We're looking for a Software Engineer to join our early engineering team and help build CatchBack from the ground up.

You'll work across the stack and own meaningful parts of the product—from customer-facing experiences used by thousands of collectors to the backend systems responsible for payments, inventory, marketplaces, and real-time pack openings.

This is a high-ownership role. You'll ship directly to production, work closely with the founders, talk to users, and have significant influence over both our product and technical direction.

What You'll Work On

• Build and ship new consumer-facing features across web and mobile
• Design reliable backend systems for transactions, inventory, payments, and marketplace activity
• Build real-time and interactive experiences around pack openings and collectibles
• Improve performance and reliability as transaction volume scales
• Integrate payments, logistics, authentication, and third-party APIs
• Develop internal tools that help our operations team manage thousands of physical collectibles
• Help make architectural and infrastructure decisions as we scale
• Own projects end-to-end, from product discussions through deployment and monitoring # What We're Looking For
• Strong software engineering fundamentals
• Experience building and shipping production applications
• Comfortable working across the stack
• Experience with modern TypeScript/JavaScript ecosystems
• Familiarity with React/Next.js and backend/API development
• Strong understanding of databases and data modeling
• Ability to move quickly without sacrificing reliability
• Comfortable operating in an early-stage environment with ambiguity and high ownership
• Strong product instincts—you care about what users experience, not just whether the code works

Experience with high-volume consumer applications, payments/fintech, marketplaces, gaming, real-time systems, or mobile development is a plus, but isn't required.

How We Work

We're a small team and operate with a high degree of ownership. Engineers aren't handed fully specified tickets—they're expected to understand the problem, contribute to the solution, build it, and see how users respond. The ideal candidate would be both technically talented as well as product minded.

We ship quickly, care deeply about the product, and believe some of the best work happens when engineering, product, and design sit together.

This role is in-person in San Francisco.

Why CatchBack

You'll join at a stage where individual engineers can still meaningfully shape the company. You'll have the opportunity to own major systems, work directly with the founders, and help define the engineering culture as the team grows.

If you like building consumer products, moving quickly, and seeing your work immediately used by real customers, we'd love to hear from you.
