Join L3Harris and the ATLAS team to build and operate mission-critical backend and deployment capabilities that directly support the U.S. Space Force. In this role, you’ll combine modern backend development with hands-on DevOps responsibilities to ensure our services run reliably across multiple environments. You’ll use Java, Spring Boot, SQL, and Kubernetes to design, develop, deploy, and sustain high-impact services for the Advanced Tracking & Launch Analysis System, enabling operators to make better decisions in a space mission environment. This position offers meaningful national security impact, strong technical collaboration, and the opportunity to see both your code and your operational tooling used in real-world missions.

Essential Functions

• Design, develop, test, and sustain backend microservices and APIs using Java, Spring Boot, and SQL to support operational and training capabilities.
• Develop services that support concurrent training scenarios, including execution coordination, scenario-data management, and lifecycle operations.
• Collaborate with application and systems architects to implement scenario-time control, state capture and restoration, and replay across distributed services.
• Design and implement Kubernetes deployment and orchestration solutions for concurrent training environments, including automated provisioning, workload isolation, and resource management.
• Evaluate and integrate virtual-cluster technologies with the Platform Services Administration team to meet isolation, scalability, security, and operational requirements.
• Collaborate with platform, DevOps, and integration teams to establish service interfaces, deployment automation, configuration practices, and integration testing.
• Develop automated tests and observability capabilities to validate application functionality, scenario-data integrity, and deployment reliability.
• Troubleshoot and optimize backend services, database interactions, and Kubernetes workloads across development, test, staging, and operational environments.
• Work with systems engineers, front-end developers, testers, and mission operators to deliver reliable, resilient capabilities.

Qualifications

• Bachelor’s degree and a minimum of 6 years of prior relevant experience; graduate degree and a minimum of 4 years of prior related experience; or, in lieu of a degree, a minimum of 10 years of prior related experience.
• Strong hands-on experience developing backend microservices and APIs using Java, Spring Boot, and SQL.
• Experience designing, testing, and troubleshooting distributed applications, including concurrent processing, service coordination, and data consistency.
• Hands-on experience deploying and managing Kubernetes-based applications, including deployment automation, workload isolation, resource configuration, and troubleshooting.
• Experience developing data initialization, provisioning, or lifecycle-management capabilities for training, simulation, testing, or comparable multi-instance environments.
• Experience with CI/CD, automated testing, and application configuration management.
• Experience collaborating across application development, platform administration, DevOps, and integration teams.
• Experience working in Linux and Windows Server environments.
• Must hold or be able to obtain and maintain a U.S. Secret security clearance.

Preferred Additional Skills

• Experience with simulation-time control, state checkpointing and restoration, event replay, or reproducible scenario execution.
• Familiarity with concurrency control, event ordering, idempotency, and distributed state management.
• Experience with Kubernetes virtual clusters, such as vCluster, or comparable multi-tenant isolation technologies.
• Experience with Helm, Kubernetes operators, custom resource definitions, infrastructure as code, or GitOps.
• Experience implementing application and infrastructure observability, including logging, metrics, and tracing.
• Experience with GraphQL APIs or similar data-querying technologies.
• Background in space operations, Space Domain Awareness (SDA), or orbital modeling and simulation.
