The Opportunity We are looking for an ambitious frontend engineer to own bigger and bigger portions of our UX, as part of an 0-1 initiative. With Postman Insights , our vision is to help guide a developer with little previous experience—in both the system being monitored and the Postman API Platform—to productively find and fix issues. Our goal is to be able to help any developer locate API endpoints causing potential issues within 15 minutes of signing up for an account. This will empower even a new developer to find and fix issues in their first days on the job, as easily as they can call an API today. As we prepare to launch our open beta, we’re looking for a frontend software engineer to help us bring our Postman Insights product to life. Right now, we’ve launched an alpha to a small number of users and have learned a lot from that launch. To deliver our intended developer experience, we’ll need to iterate with our users to get the UX right. We’re looking for an engineer who can focus on the frontend, excited about designing and refining the user interface on a weekly basis to get our product ready for a larger number of users.
