Senior Software Engineer — Secure Mission Systems
Location: Mainly remote, with onsite work in Laurel, Maryland, typically one day approximately every six weeks for team-wide sprint planning
Clearance: Active final DoD Secret clearance required
Build Secure Software for High-Impact Defense Missions
Rackner is seeking a Senior Software Engineer to design, build, test, and deliver secure mission-planning and decision-support software for a Department of Defense customer.
This role gives you broader ownership than a traditional feature-development position. You will contribute across application engineering, secure CI/CD, containerized deployment, automated testing, cybersecurity remediation, and AI-capability integration. You will work alongside experienced technical teams and help move complex software from design through secure delivery.
This position is contingent upon contract award and final customer approval.
What You Will Do
- Design, develop, test, and integrate new software capabilities.
- Build and maintain secure CI/CD workflows using GitLab and related development systems.
- Support containerized application deployment through OpenShift and Kubernetes.
- Apply secure software-development lifecycle practices throughout delivery.
- Integrate AI models and support capabilities involving LLM assistants, retrieval-augmented generation, and agentic AI.
- Develop unit, integration, and system-level tests.
- Use automated security tools such as Fortify, JFrog Xray, and OWASP ZAP.
- Investigate vulnerabilities and support cybersecurity remediation.
- Participate in code reviews, technical reviews, and solution-design discussions.
- Create software-design documents, sequence diagrams, workflow descriptions, and test reports.
- Communicate progress, blockers, risks, and schedule concerns to technical and program stakeholders.
- Collaborate with customer technical leads in remote and onsite settings.
What You Will Bring
- Bachelor’s degree in Computer Science or a related field
- 10+ years of software engineering experience, including hands-on design, development, testing, or integration work
- Hands-on experience with CI/CD, Kubernetes, GitLab, and OpenShift
- Strong understanding of secure software-development lifecycle practices
- Experience using Fortify and/or JFrog Xray for automated security scanning and vulnerability remediation
