    Job Description

    Upwork ($UPWK) is the world’s work marketplace. We serve everyone from one-person startups to over 30% of the Fortune 100 with a powerful, trust-driven platform that enables companies and talent to work together in new ways that unlock their potential. Last year, more than $3.8 billion of work was done through Upwork by skilled professionals who are gaining more control by finding work they are passionate about and innovating their careers. This is an engagement through Upwork’s Hybrid Workforce Solutions (HWS) Team. Our Hybrid Workforce Solutions Team is a global group of professionals that support Upwork’s business. Our HWS team members are located all over the world. The UDE product enables local and remote development by combining solutions based on dev containers and Okteto for each mode. It builds on a bubbletea/golang TUI-based solution and extensive development to adapt the respective technologies for Upwork use cases. The UDE team is responsible for all aspects of the product, including development, support, and documentation.

    Responsibilities:

    • You will be implementing features primarily in local runtime and dev containers and evolving the product for more use cases.
    • You will collaborate with the developer community to evolve the product architecture and enable adoption at scale.
    • You will participate in supporting the product, responding to requests for troubleshooting and questions on usage.

    The ideal candidate combines enterprise-grade development experience with knowledge of deploying K8s workloads in an AWS EKS environment. While K8s operations are not in scope, developing and supporting remote development functionality necessitates this knowledge.

    • Additionally, close collaboration with a diverse developer community is key; experience in a development experience/toolset role is highly desirable.

    Must Haves (Required Skills):

    • High-level experience (minimum of 5 years) of software development in Java-based microservices in an enterprise environment and under SDLC processes.
    • High-level experience in Python to support key utilities used in the deployment process.
    • Experience in UI development.
    • Experience with Docker containerization, including writing Dockerfiles, managing container lifecycles, and integrating with development workflows.
    • Experience with deploying workloads on K8s environments, in particular the development of K8s manifests and working with Helm.

    Nice-to-have Skills:

    • Experience with Golang.
    • Remote development and sandbox solutions in general, and Okteto in particular.
    • Cross-platform Golang and Bash scripting.

    Dev containers. CI/CD pipelines. Upwork is proudly committed to fostering a diverse and inclusive workforce.
