Job summary

OpenRouter, Inc is hiring Software Engineers for our Product team to build dashboards, admin tooling, billing and spend management, analytics, onboarding, and other user-facing features that turn OpenRouter into a platform. You’ll work closely with PMs and our designer to ship and own pieces end to end.

This role is ideal for engineers who value autonomy, collaboration, and have a track record of shipping software that works.

Qualifications

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 and automate your work.

Responsibilities

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.
Bring a strong product instinct — push back when something doesn’t make sense, and propose your own ideas.
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 frontend and backend systems.
Help raise the bar for product quality, design polish, and craft as the team grows.
