The Opportunity
The Customer Journey team at Postman is responsible for shaping how users experience the product from their first interaction through to becoming active, engaged customers.
We own the critical paths between sign-up and purchase including new user onboarding and the moments where users discover and adopt key features. As Postman expands what it means to be a customer, from enterprise organizations to teams of engineers to individual developers working with AI agents, this team plays a central role in defining and evolving those experiences.
We’re looking for a Senior Engineer who is excited to build and improve product journeys end-to-end. You’ll work at the intersection of product, design, and engineering to create intuitive, high-quality experiences that help users find value in Postman—whether they’re exploring on their own or collaborating as part of a team.
What You’ll Do
Own and improve key product journeys from sign-up through onboarding, feature discovery, and purchase
Build and refine user experiences that help developers and teams quickly understand and realize the value of Postman
Design and implement features that drive adoption of core platform capabilities across different user types (individuals, teams, and AI-assisted workflows)
Partner closely with Product, Design, and Data to identify opportunities and prioritize improvements across the user journey
Use experimentation and analytics to inform decisions and validate the impact of changes
Develop a deep understanding of how developers use Postman—individually and collaboratively—and apply those insights to improve the product
Iterate quickly, delivering thoughtful, incremental improvements that compound over time
Contribute to the evolution of our onboarding and discovery systems as the product and customer base continue to grow
About You
Must have:
8+ years of experience building frontend or full-stack applications with a focus on product and user experience
Strong fundamentals in JavaScript, HTML, and CSS; experience with modern frameworks like React or Next.js
Track record of building and improving product experiences that drive user engagement and adoption
Experience using data, analytics, or experimentation to guide product decisions
Strong product sense and attention to detail—you care deeply about how things work and feel
Ability to take ownership of ambiguous problem spaces and drive them to clear outcomes
Excellent communication skills and experience collaborating across functions
Curiosity about how developers work, and a desire to build tools that make them more effective
Nice-to-have:
Experience with full-stack JavaScript / TypeScript
Experience with state management tools like MobX
Experience working on B2B products, developer tools, or AI-powered experiences
Experience working in a fast-paced, startup environment
This role is based in the greater San Francisco area, and the reasonably estimated salary for this role ranges from $210,000 to $240,000 plus a competitive equity package. Actual compensation is based on the candidate's skills, qualifications, and experience.
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.

Our frequent and fascinating team-building events will keep you connected, while our donation-matching program can support the causes you care about. We’re building a long-term company with an inclusive culture where everyone can be the best version of themselves.
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.

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.
