Our fast-growing customer base includes hundreds of modern software companies building the next generation of enterprise-ready products.

About the Infrastructure Team

The Infrastructure team powers the core systems behind the WorkOS platform. We build and maintain the foundation that keeps everything running smoothly—handling millions of requests, operating at scale, and ensuring our systems are fast, reliable, and always on for our customers.

Our team works across the stack and partners closely with teams throughout the company. We regularly step in to support high-impact projects, contribute architectural perspective, and ensure systems are built to scale.

- Are curious and proactive, with a strong desire to understand how systems work end-to-end

- Partner well with product engineering teams to design systems that are reliable, scalable, and easy to operate

- Work independently, take ownership, and follow through—from identifying a need to shipping a solution

- Contribute to technical design reviews and architectural discussions

- Document your work, share context, and help level up the team through thoughtful collaboration

- Bring a spirit of curiosity—experimenting, iterating, and helping us find better ways to build and operate our systems
