Contract: Senior Software Engineer - Unified Developer Environment (UDE) at Upwork

This role is designed for a Senior Software Engineer with a deep background in enterprise-grade Java microservices who has pivoted toward **Developer Experience (DevEx)**. The ideal candidate isn't just a coder; they are an internal tooling specialist who understands the "inner loop" of development. You should be comfortable building CLI tools and managing containerized environments to help other engineers work more efficiently. This is a **fully remote contract engagement** specifically for talent based in **Europe**, managed through the Hybrid Workforce Solutions team. You will be working on the "Unified Developer Environment" (UDE), a critical internal product built on Golang, Docker, and Kubernetes (AWS EKS). It is a unique opportunity to shape the infrastructure that hundreds of other developers use daily. **You might be a good fit if you...** * Have 5+ years of experience with enterprise Java microservices and a solid grasp of Python for utility scripting. * Are an expert in Docker and Kubernetes (Helm/Manifests), specifically regarding containerized development workflows. * Enjoy "meta-work"—building tools, documentation, and support systems that improve the lives of other software engineers. * Have experience or a strong interest in Golang, dev containers, and remote development platforms like Okteto.
