The MDS mission is to provide world-class Radar and Command and Control (C2) software across an array of surveillance and warning systems. Platform Engineers design, optimize and maintain the secure, scalable, mission-critical software infrastructure that underpins radar, C2 and DevSecOps-intensive systems. As a senior leader on our team, you will help shape platform architecture, drive modernization and ensure delivery of robust capabilities that support real-time mission execution across programs. This role requires deep DevSecOps expertise, technical leadership and the ability to influence architecture and engineering strategy across multiple teams. This position is located onsite in Tewksbury, Massachusetts. What You Will Do * Implement the platform architecture and modernization strategies for C5I mission systems, including automation, container orchestration and secure platform design. * Develop resilient, scalable, and secure platform environments using Linux, Kubernetes, Docker, Terraform, Ansible, Artifactory and related technologies. * Work on end-to-end DevSecOps workflows to support high-frequency, high-quality deployments across MDS programs. * Work on CI/CD pipelines (Jenkins, GitLab CI/CD) to ensure secure, automated build, test and release processes at scale. * Work on cross-program integration efforts spanning Software, Systems Engineering, Cybersecurity, Platform and Integration & Test teams. * Conduct debugging and performance optimization across distributed and containerized environments. * Help mentor and guide Platform Engineers, providing technical direction and fostering a culture of learning and collaboration. * Provide leadership in Agile Scrum/Kanban environments, supporting planning, estimation and technical execution. What You Will Learn * Advanced real-time radar and C2 system behavior, multi-sensor data processing and secure distributed system design. * DevSecOps transformation efforts across classified environments. * Strategies for scaling platform engineering capabilities across multiple mission programs., Onsite: Employees who are working in Onsite roles will work primarily onsite. This includes all production and maintenance employees, as they are essential to the development of our products. Candidates will learn more about role type and current site status throughout the recruiting process. For onsite roles, commuting to and from the assigned site is the employee's personal responsibility. This position requires a security clearance.
