Software Engineer, Product at Openrouter

ABOUT OPENROUTER OpenRouter is the leading AI routing and infrastructure layer that enterprises use to access, manage, and optimize the best large language models across providers—without lock-in, capacity constraints, or unnecessary cost. We power the most advanced AI teams in the world by giving them the flexibility to move fast, scale confidently, and stay future-proof as models evolve. 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 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 land on either our product teams, 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. ABOUT YOU - 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. BONUS POINTS - Prior experience at fast growing applied AI or product led companies - Experience building product in fast-moving, ambiguous industries. - Existing user of OpenRouter or active side projects in AI tooling. The base salary for this full-time position in the United States, spanning multiple internal levels depending on qualifications, ranges between $215,000 to $285,000 plus benefits & equity. Compensation for internationally based candidates will vary to reflect local market conditions. 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.
