Software Engineer, Platform en OpenRouter

Remoto - Remote (US)

OpenRouter is a leading AI routing and infrastructure layer that enables enterprises to access, manage, and optimize large language models across providers.

Salary

USD 215,000 - 285,000

Requirements

Skills

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 (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
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

Responsibilities

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
