• Work with Experts: Collaborate with a top-tier team of engineers, scientists, and technicians located across the U.S.
• Shape the Future: Influence both the strategic and tactical direction of next-generation subsea technologies.

What You’ll Do

• Serve as a Systems Engineer, developing and maintaining system-level architectures, interfaces, and design artifacts across the program lifecycle.
• Lead and support TEMPALT development, ATO packages, and system safety analyses, including coordination with program, cybersecurity, and safety stakeholders.
• Develop system-level test strategies and plans, and coordinate verification and validation activities across multiple teams and test venues.
• Provide Technical Data Package oversight, ensuring technical integrity, configuration control, and compliance with contractual and program requirements.
• Perform and review reliability and safety analyses, including FMEA and FMECA, and ensure findings are appropriately mitigated and documented.
• Apply Model-Based Systems Engineering practices using Cameo to support requirements, architecture, and traceability.
• Collaborate across disciplines to integrate hardware, software, and control systems into cohesive system solutions.
• Mentor and provide technical guidance to mid-level and junior systems engineers.

SUBSEAMSS

At Leidos, we don’t want someone who "fits the mold"—we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, “what’s next?” before the dust settles on “what’s now.”

If you’re already scheming step 20 while everyone else is still debating step 2… good. You’ll fit right in.
