At Postman, we are revolutionizing the way developers build, trace, and automate API workflows with Postman Flows, a powerful visual programming tool designed to simplify the development and sharing of API‑powered applications. With an intuitive drag‑and‑drop interface, Postman Flows enables teams to collaborate and showcase their APIs regardless of technical expertise.

We are looking for a Software and Systems Engineer to help scale and maintain the Flows runtime system. This system runs mission‑critical automations in the cloud, with a focus on low latency, high throughput, and high availability. You’ll play a vital role in developing, deploying, and operating our backend services and infrastructure in a Kubernetes‑based cloud environment.

We’re looking for an experienced engineer who is excited not only about hands‑on building as we ship and iterate on a weekly basis to get our product ready for GA, but who can also serve as a role model and mentor to other engineers. This role involves making key technical decisions and improvements to the system, as well as effectively making impact through influence within and across teams that span multiple time zones.

If you’re driven to deliver high‑quality solutions, we want you on our team!
