Sr. Engineer, Client Platform (UI Platform)
About The Position
As a Senior Software Engineer on the Client Platform team, you’ll help shape the front-end foundations that Postman relies on. This includes the design system and the reusable components that power both web and desktop experiences. Your work will influence how hundreds of engineers build, improving consistency, performance, and the overall developer experience. This is a hands-on role. You’ll build components, help define UI architecture, and partner with engineers and designers to turn ideas into scalable UI systems. In practice, you’ll push the UX layer forward, enabling teams to ship high-quality features without reinventing core patterns.

- Familiarity with accessibility and internationalization principles.
- Experience improving developer experience through process, documentation, and/or tooling.
- Able to independently lead medium-to-large technical projects and contribute thoughtfully to team-level architectural decisions.
Responsibilities
- Evolve front-end architecture, including component libraries, layout patterns, theming, and global UI behaviors.
- Implement specialized UI components where needed (e.g., editors, grids, structured data components) with a focus on performance and usability.
- Ensure components support accessibility, keyboard interaction patterns, and internationalization/localization standards.
- Support product teams in adopting UI Platform components and patterns, providing guidance and identifying opportunities to simplify or extend the platform.
- Contribute to documentation, developer tooling, and internal processes that make it easier to build high-quality UI consistently.
