Senior Full-Stack Engineer (Remote, US)

We are looking for a** Senior Full-Stack Engineer with 8+ years of experience** to join a small, high-caliber engineering team building the world's first open exchange for GPU compute. You'll be a peer to two very senior developers, expected to hit the ground running and operate as an architect, planning features, writing specs, directing AI coding agents, and validating high-quality output. This is a startup where engineers think like founders: self-directed, entrepreneurial, and comfortable wearing multiple hats across a fast-moving product. The ideal candidate is back-end heavy but capable across the full stack, with experience in e-commerce or marketplace systems involving inventory, orders, and customer workflows.

What will you be doing?

• Architect and build scalable backend services and frontend features for a compute marketplace, including inventory management, order workflows, RFQs, and invoicing

• Plan and spec out features, then use AI coding agents (e.g., Codex, Claude) to accelerate delivery while validating quality and correctness

• Extend platform capabilities with KYC/KYB automation, enhanced Slack integrations, live chat, and AI-powered customer support

• Own production reliability, design, deploy, and maintain systems end-to-end with a focus on performance and maintainability

• Participate in daily standups, contribute to product discussions, and pitch in across the business as needed, including customer support and ticket resolution
