Job description

Standard Job Description

This position is for a Mission Assurance Software Engineer Senior supporting Anti-Tamper software development on the F-35 Joint Strike Fighter (JSF) and Integrated Fighter Group (IFG) platforms. Opportunities to support other LM Aero platforms may become available as the candidate progresses in this role. Daily tasks include, but are not limited to, the following:

• Develop, maintain, and execute unit tests and requirements‑driven test suites for mission‑critical software components.
• Participate in Agile ceremonies (scrum, sprint planning, retrospectives) and use Agile tools (Jira, Confluence, etc.) to track work and deliverables.
• Implement software features using C/C++ in a Linux environment; manage source code with GitLab (branching, merging, pull‑requests).
• Design and develop middleware components that enable communication between subsystems.
• Build, configure, and maintain CI/CD pipelines (GitLab CI, Jenkins, etc.) to automate builds, static analysis, testing, and deployment.
• Perform embedded software development, including memory‑mapped hardware access, bare‑metal coding, and real‑time operating system (RTOS) integration.
• Conduct root‑cause analysis of software anomalies: fault isolation, debugging, and after‑action reporting.
• Collaborate with system engineers, hardware engineers, and test teams to ensure software meets interface, performance, and security requirements.
• Produce and maintain technical documentation, test procedures, and operational guidance.
