About the Role
We're hiring Software Engineers for our Product team to build the surfaces our customers depend on — dashboards, admin tooling, billing and spend management, analytics, onboarding, and many other user-facing features that turn OpenRouter into a platform. You'll be working closely with PMs and our designer to ship. We have a small team focused on this surface today, so you'll have room to own pieces of the product end to end.
This role is ideal for engineers who love autonomy, value collaboration, and have a track record of shipping software that works. You’ll play a critical role in shaping our product as we scale, helping expand our platform’s features, and delivering exceptional experiences for our users.
What You'll Do
Build and ship high quality customer-facing products and features.
Own products from concept to production, ensuring they are performant, reliable, and delightful for users. Make good product and design decisions, and be open to feedback and collaborative creation.
Bring a strong product instinct — push back when something doesn't make sense, and propose your own ideas to help make our product even better.
Partner with product and design teams to shape what we build, not just how we build it.
Identify bottlenecks, build great monitoring, propose solutions, and optimize performance across both frontend and backend systems.
Help raise the bar for product quality, design polish, and craft as the team grows.
What We're Looking For
4+ years of experience shipping external-facing products as a full-stack or product engineer with strong product taste and judgment.
Proficient in React, TypeScript, Next.js, and JS runtimes.
High agency and a bias toward action; you talk to users, you iterate, you ship.
AI-forward in your workflow. You use coding agents often, found interesting ways to automate your work, and have opinions about what works and what doesn’t
Comfortable in a small, fast-moving environment where boundaries between teams are intentionally fluid.
Strong written communication and a collaborative working style with PMs and designers.

As enterprise adoption of AI accelerates, OpenRouter sits at the center of how organizations operationalize LLMs across research, product, and production workloads.
About the Role
We're hiring a Software Engineer on our Platform team to own and scale the systems that route and serve millions of LLM requests every day. The business is growing at an unbelievable pace and we need help to ensure our platform can keep up. You'll work alongside a small team of engineers on owning our infrastructure, datastores, CI/CD pipeline and everything else at OpenRouter is built on. This is a hands-on IC role with broad surface area and little process between you and shipping.
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.
What We're Looking For
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.

About OpenRouter
OpenRouter is the unified interface for large language models. We route billions of tokens every month, helping developers build AI applications without worrying about provider lock-in, downtime, or complex integrations. We're a small, focused team backed by top-tier investors.
About the Role
We're looking for a Scaled Support Specialist who lives at the intersection of deep technical troubleshooting and exceptional human communication. You'll be the front line for developers integrating with OpenRouter's API — diagnosing complex issues across dozens of model providers, untangling new edge cases, and making sure every developer who reaches out feels like they have a partner, not a ticket number.
This is not a scripted helpdesk role. Our users are highly capable engineers building the next generation of AI applications, which means the problems they bring to us are complex, nuanced, and frequently novel. You'll encounter issues daily where there is no runbook. You'll need to figure it out, often with incomplete information, and usually before anyone else on the team has seen it either.
If you're the kind of person who reads API changelogs for fun, has strong opinions about error message quality, and gets genuine satisfaction from turning a frustrated developer into a happy one — keep reading.
What You'll Do
Troubleshooting & Problem Solving (Core Focus)
Diagnose and resolve complex technical issues across OpenRouter's API, spanning multiple LLM providers
Reproduce bugs in ambiguous environments — different SDKs, languages, frameworks, and auth configurations — using tools like curl, Postman, and small test apps
Read and interpret logs, headers, and request traces; identify whether the problem is client-side, OpenRouter-side, or an upstream provider issue vs. a user misconfiguration
Turn "it doesn't work" into actionable findings: exact steps to reproduce, clear hypotheses, and verified fixes or workarounds
Developer Communication & Advocacy
Respond to developer inquiries across support channels (email, Discord, GitHub) with clarity, empathy, and technical precision
Translate complex technical root causes into human-friendly explanations
Set expectations on timelines and next steps; provide proactive updates and close the loop
Identify patterns in support requests and advocate internally for documentation improvements, API design changes, or better messages
Self-Directed Research & Learning
Stay current with the rapidly evolving LLM ecosystem
Develop deep expertise in OpenRouter's routing logic, fallback behavior, rate limiting, streaming (SSE), and billing systems with minimal hand-holding
Bridge to Product & Engineering
Spot systemic issues underneath individual tickets and push for the fix that prevents 50 more
Identify trends in support volume to capture product feedback and inform roadmap priorities
Collaborate on improving the developer experience
What We're Looking For
4+ years in a technical support, developer support, solutions engineering, or similar role — ideally supporting an API or developer tools product
Exceptional troubleshooting instincts
Strong API fluency
Proficiency in at least one scripting language (Python or TypeScript)
Excellent written communication
Comfort with ambiguity
Genuine passion for AI and LLMs
Nice to Haves
Familiarity with the OpenAI SDK / Chat Completions API format
Experience with AI/ML frameworks like LangChain, LlamaIndex, or Hugging Face
Experience with observability tools (logging, tracing, metrics)
Experience scaling support operations — e.g., implementing AI-assisted support bots, building internal support dashboards, or creating automated triage workflows
Contributions to open-source projects or developer communities
Background in or exposure to ML/AI concepts beyond just using APIs (benchmarking, evals, fine-tuning)
If you don't think you meet all of the criteria below but still are interested in the job, please apply. Nobody checks every box, and we're looking for someone who is excited to join the team.
