Software Engineer, Platform

What You'll Do

• Own and evolve our edge and cloud infrastructure across Cloudflare, Google Cloud, and Vercel.
• Scale and operate our data layer including Spanner, ClickHouse, and Postgres.
• Ensure we are optimizing for performance when serving LLM inference as traffic rapidly grows.
• Partner with engineering leadership on capacity, reliability, and cost across the routing layer, with ownership of the systems carrying production traffic.
• Set the bar and playbook for how we run infrastructure and operations as the team grows — tooling, observability, on-call, and the patterns other engineers build against.

About You

• 5+ years building and operating production infrastructure at companies where uptime, latency, and cost matter.
• Proven experience with cloud platforms (GCP, AWS, Azure) and edge-first serverless platforms (e.g. Cloudflare Workers).
• Deep expertise in operating large scale databases (e.g Postgres, Spanner, etc).
• A full-stack TypeScript shop won't faze you; you can move across the stack when the platform needs it.
• High agency and a bias toward action. You don't wait for tickets — you see the bottleneck and fix it.
• AI-forward in your workflow. You use coding agents, MCPs, and LLMs heavily and have opinions about what works.
• Pragmatic about tradeoffs between speed and simplicity.

Bonus Points

• Existing user of OpenRouter, or active side projects in AI products/infrastructure or developer tooling.

Compensation: Base salary $215,000 - $285,000 plus benefits & equity (US full-time). International compensation varies by local market.
