Job description

The Opportunity

As a Senior Backend Engineer on the Cloud Platform team, you will play a key role in building the core systems and services that power Postman's internal platform. You'll help create new backend services that manage how we deploy, scale, and operate our infrastructure and product services, leveraging Java, Spring Boot, and Hibernate (JPA) on top of cloud-native technologies like Kubernetes, ArgoCD, Istio, and Terraform.

This role is highly impactful: the systems you build will be used across Postman engineering, enabling faster delivery, better scalability, and a stronger developer experience. You'll also have the opportunity to contribute to open source, shaping tools that extend beyond Postman's boundaries.

What You'll Do
  • Design and develop backend services in Java and Spring Boot to support Postman's internal Cloud Platform.
  • Architect new services that manage service deployment, lifecycle, and scaling across Kubernetes clusters.
  • Implement GitOps workflows (ArgoCD) to support continuous delivery.
  • Integrate with cloud-native tooling such as Istio, Helm, and Terraform.
  • Apply strong software engineering practices: testing, code reviews, CI/CD, and documentation.
  • Drive innovation by contributing to open-source projects where applicable.
  • Collaborate cross-functionally with Cloud Architects, DevOps engineers, and product teams to align solutions with business needs.
  • Ensure performance, reliability, and scalability of services that run at Postman's scale.
About You
  • 5+ years of professional experience in backend software development.

  • Strong expertise in Java, Spring Boot, and Hibernate (JPA).

  • Proven experience designing and maintaining APIs and distributed backend services.

  • Familiarity with Kubernetes, Argo, Istio, and Terraform.

  • Strong understanding of software design principles (scalability, extensibility, resilience).

  • Experience with build and testing tools (Gradle, Maven, JUnit).

  • Proficiency with Git and Gitflow workflows.

  • Excellent collaboration and communication skills.

  • Strong security mindset and awareness of compliance frameworks.

The reasonably estimated base 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.
