You contribute directly to an in-house PaaS software solution that supports a cutting-edge sensor platform in a highly specialized defense setting.

Responsibilities

• Build, enhance, and sustain a Kubernetes-based Platform-as-a-Service, including clusters running on physical systems, virtualized environments, and virtual clusters.
• Develop and maintain shared platform services that provide common capabilities to application teams, such as routing and utility services, alerting, cluster-level protections, and data processing services.
• Implement and maintain Kubernetes-native integrations, including operators and controller patterns that extend and automate cluster functionality.
• Support and improve CI/CD pipelines using GitLab, including designing pipeline stages, integrating scanning tools, configuring automated checks, and managing promotion workflows.
• Perform Linux-based installation and configuration activities in air-gapped systems, focusing on automation and repeatable deployment workflows.
• Support phased deployment and test promotion flows, moving solutions from virtual or small systems through miniature systems to full system deployments.
• Contribute to quality practices by implementing automated checks, fail-fast validations where appropriate, and broader pipeline and system testing.
• Collaborate using the Atlassian toolset, including Jira and Confluence, for planning, tracking work, and maintaining documentation.
• Work with cybersecurity and platform controls at the cluster level, including integrating scanning tools and configuring security-related platform settings.
• Partner with application teams to ensure platform services, CI/CD workflows, and Kubernetes capabilities effectively support mission applications in constrained environments.

Essential Skills

• Bachelor’s degree in Computer Science or a related field, or equivalent experience.
• 3–5 years of professional software engineering experience.
• Hands-on experience developing backend services using Golang (Go), including microservices and APIs.
• Experience with JavaScript to support React-based frontends.
• Experience deploying applications into existing Kubernetes environments at the service level.
• Experience working in air-gapped, on-premises, or otherwise constrained Department of Defense-style environments.
• Ability to obtain or hold a Secret clearance.
• Proficiency with Kubernetes and containerization concepts in production or mission-focused environments.
• Experience working in Linux environments, including installation, configuration, and troubleshooting.
• Understanding of CI/CD concepts and workflows in modern software delivery pipelines.

Additional Skills & Qualifications

• Familiarity with gRPC and service-to-service communication patterns.
• Experience using GitLab for source control and interacting with CI/CD pipelines.
• Exposure to React (JavaScript) for building lightweight dashboards or graphical user interfaces.
• Understanding of API-based architectures, including clear separation of frontend, middleware, and backend services.
• Experience with unit testing and delivering high-quality, well-tested code.
• Knowledge of secure systems, including encryption in transit, secure APIs, and cybersecurity best practices.
• Experience collaborating with cross-functional teams using tools such as Jira and Confluence.
• Experience working with routing, alerting, and data processing services in distributed systems.
• Interest in platform engineering and building shared services that support multiple application teams.
