The Client Platform organization provides the paved path for building, testing, and releasing Postman’s web and desktop applications. We own frameworks, design systems, SDKs, build tooling, and shared infrastructure that product engineers depend on every day. The UI Platform group focuses on creating reliable, accessible, and performant UI foundations used across Postman.
The OpportunityAs 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.
What You’ll Do- 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.
Identify UI-related technical debt or architectural gaps and proactively drive improvements.
Mentor other engineers, participate in design reviews, and influence technical decision-making.
You enjoy creating clean, scalable components and UI patterns that others depend on.
You think beyond features and consider how systems evolve. You take ownership of problems, not solutions.
You communicate clearly and listen effectively. You seek new perspectives and build trust with your team and colleagues.
You care about performance, reliability, and the little things that make interfaces feel polished.
Your Experience
6+ years building UI for complex web applications.
Deep understanding of JavaScript/TypeScript and React.
Experience creating and maintaining reusable component libraries or design systems.
Strong knowledge of UI performance, including rendering costs, bundling, and responsive interaction 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.
The reasonably estimated base salary for this role ranges from $220,000 to $240,000, plus a competitive equity package. Actual compensation is based on the candidate's skills, qualifications, and experience.
