The Opportunity

The Client Platform team is seeking a Senior Frontend Engineer to help us raise the quality bar across our frontend ecosystem. You'll establish engineering excellence through improved architecture, performance optimization, and maintainable code patterns that ensure our platform delivers exceptional experiences to both internal engineering teams and our 35+ million customers. This role is a unique opportunity to have immediate impact on the foundation that hundreds of Postman engineers rely on daily.

What You'll Do

The Client Platform team is a global engineering organization responsible for creating a "paved path" for all Postmanauts to develop and release web-based applications. Our platform is the foundation that hundreds of engineers at Postman rely on daily to deliver new features and improvements to over 30 million customers. We manage everything from build tooling and shared libraries to development infrastructure, best practices and our cross-platform desktop application.

Specifically you will:

• Design and develop modular, well-documented SDKs and component libraries that serve both internal engineering teams as well as external developers, with focus on usability, accessibility, performance, and cross-platform compatibility.
• Architect extensible frontend systems with clear boundaries, well-defined interfaces, and appropriate abstraction layers that balance customization needs with consistency requirements
• Establish and evangelize architectural patterns that promote code quality, maintainability, and scalability across Postman's frontend ecosystem
• Champion engineering excellence through active participation in architectural decisions, mentorship of other engineers in frontend best practices, and creation of standards that become embedded in our engineering culture and measurably improve code quality
• Proactively partner with product and engineering to identify, prioritize, and eliminate technical debt through strategic refactoring and system enhancements, driving improved development velocity and platform reliability.

About You

• 8+ years in Frontend software engineering with demonstrated expertise in code quality, performance optimization, and engineering excellence.
• Deep understanding of modern web technologies and best practices (JavaScript, TypeScript, React, state management, testing frameworks, etc.).
• Experience designing and implementing maintainable, scalable frontend architectures for complex applications, including component libraries and SDKs that can be effectively reused across multiple systems.
• Proven track record of raising the quality bar in previous roles through both technical solutions and positive cultural impact.
• Additionally, you are someone who:
• Communicates clearly and listens effectively. You seek new perspectives and build trust with your colleagues.
• Loves the challenge of constraints and excels at finding creative solutions.
• Takes ownership of problems, not solutions, and celebrates success as a team.

Nice-to-have:

• Experience with cross-platform applications (Electron or similar) and understanding the unique challenges of desktop/web hybrid environments.
• Creating widely-adopted (open source) libraries/SDKs with 1000+ active developers.

What Else?

In addition to Postman's pay-on-performance philosophy, and a flexible schedule working with a fun, collaborative team, Postman offers a comprehensive set of benefits, including full medical coverage, flexible PTO, wellness reimbursement, and a monthly lunch stipend. Along with that, our wellness programs will help you stay in the best of your physical and mental health. Our frequent and fascinating team-building events will keep you connected, while our donation-matching program can support the causes you care about.

At Postman we value in person collaboration. We are in office 5 days a week for all roles based out of our hubs in San Francisco Bay Area, Boston, Austin, New York City, Tokyo and London. For roles based in Bangalore, employees currently work in the office three days a week and will transition to five days per week by the end of the year. We were thoughtful in our approach which is based on collaboration and grounded in feedback from our workforce, leadership team, and peers. The benefits of our in office model will be shared knowledge, brainstorming sessions, communication, and building trust in-person that cannot be replicated via zoom.
