Senior Software Engineer- Platform & DevEx

About this role

This role sits at the intersection of software development and platform engineering, bringing a developer-first mindset to the platform team. You will design and build APIs, automation, and developer portal integrations that enable self-service capabilities and enhance the developer experience for engineering teams running workloads on GKE.

Working closely with application teams, you will help drive platform adoption by delivering scalable, reliable, and intuitive platform capabilities. This role provides an excellent opportunity for a hands-on backend engineer to grow into platform engineering, gaining expertise in GitOps, Kubernetes, service mesh, custom controllers (Go), multi-cluster operations, and production-grade platform development. You will receive mentorship and hands-on support from experienced platform engineers while progressively taking ownership of increasingly complex infrastructure and platform initiatives.

WHAT YOU WILL DO

• Design and build backend APIs (REST / OpenAPI) to provision and manage GKE namespaces and clusters - with Swagger-testable contracts, secured via OAuth2 / JWT.

• Develop platform automation: custom Kubernetes controllers and operators in Go, and/or backend microservices in Java / Spring Boot (or Node.js), to automate, environment lifecycle, and platform workflows on GKE.

• Integrate APIs with our internal developer portal (Red Hat Developer Hub / Backstage): software templates, scaffolder actions, and backend plugins so developers can self-serve namespaces and applications.

• Publish and secure APIs through an API gateway (e.g. Apigee) with SSO / OAuth2 / JWT token validation and integrate with our platform API/asset layer.

• Onboard and support application teams: help them bring their applications and microservices onto the GKE platform - deployment manifests, Helm charts, CI/CD, observability, service mesh, and connectivity, and act as their trusted partner during migration.

• Act as the voice of the developer: u...
