The Work: Lockheed Martin is seeking a talented Software Engineer with a Secret clearance to work from either our Boulder, CO or King of Prussia, PA location(s). Our portfolio powers diverse, mission-critical products, each with its own unique technical DNA.

We don't just "write code"; we engineer the automated frameworks, high-performance engines, and scalable infrastructure (Docker/Kubernetes) that ensure our entire portfolio is mission-ready. We prioritize the Engineer over the syntax.

What you'll be doing:

• Design, develop, test, and deploy software solutions that solve complex logical and mathematical problems for our mission applications.
• Drive the mission forward using Agile methodologies, participating in sprints, stand-ups, and retrospectives to ensure rapid, iterative delivery.
• Utilize modern Configuration Management practices and CI/CD pipelines to ensure code is versioned, reproducible, and deployable.
• Maintain high-quality documentation for system architectures, API designs, and operating instructions to ensure long-term system sustainability.
