Senior Fullstack Engineer

At Archive, we believe great products should live many lives. We build the technology that powers branded resale for some of the world's most beloved companies, including Lululemon, The North Face, New Balance, Dr. Martens, Peloton, and 50+ others. Our platform makes it easy for brands to keep products in circulation and for customers to shop secondhand with confidence.

The secondhand market is growing three times faster than traditional retail and is projected to reach $350B globally by 2028. We're building the infrastructure behind that shift, helping brands turn resale into a meaningful part of their business and helping consumers rethink how they shop. If you're excited to change consumer behavior for the better, we'd love to meet you.

About the role

Archive is hiring a Senior Fullstack Engineer. This is a hands-on, high-autonomy role on a small, meeting-light team that operates without a traditional product manager. You'll own features end to end, ship quickly, and help set the bar for how we build in an AI-native world.

Our day-to-day engineering workflow is AI-first: we build with tools like Claude and Devin as a normal part of how we work. You don't need to have worked in a fully AI-native environment before; what matters is genuine enthusiasm for building with AI and the judgment to use it well.

Responsibilities

Build across the stack

• Own fullstack features end-to-end, from design through release through maintenance, across a modern stack; true comfort on the backend is key
• Develop and maintain robust integrations (payments, gift cards, and beyond), building reliable, production-quality systems

Own it and collaborate

• Take real ownership in a flexible, fast-evolving environment with light process and no traditional Product Manager
• Collaborate cross-functionally to turn needs into shipped outcomes
• Share in the engineering on-call rotation (incident response and support)

Debug and strengthen the system

• Debug production issues across multiple levels of the stack
• Make pragmatic architecture and system design calls, balancing speed, scale, reliability, and maintainability

Build AI-first

• Use AI tools like Claude as a force multiplier across your workflows, with good judgment about where to trust them and where not to
• Help the team level up its AI-native development practices and set the bar for how we build in an AI-default world

Requirements

• A strong track record as a fullstack engineer with production experience across frontend and backend services, comfortable owning a feature end to end
• An AI-first dev workflow: you are ready and excited to build, review, and debug with AI coding tools and agents as a default, and can show how it makes you faster—and where you choose not to rely on it
• Bias towards action in a fast-moving, small-team environment: you ship, iterate, and take ownership without a heavy playbook
• Solid debugging and systems judgment: you can reason about an unfamiliar system and find the real problem
• Comfort with systems design and reasoning about scale, reliability, and trade-offs
• Bonus: familiarity with our stack (Next.js / React / TypeScript / Node / GraphQL / Postgres) and multi-tenant platform experience

The expected annual base salary range for this position is $180,000-$200,000, USD.
