Autonomous Mission Systems Software Engineer

Description

Build software for UUVs that navigate in the dark, think independently, and must complete the mission. Failure is not an option.

Leidos is seeking an Autonomous Mission Systems Software Engineer to help develop and evolve the Sea Dart UUV product line
, a family of undersea autonomous systems built to operate independently, coordinate with operators, and execute complex missions in denied environments.

This role sits at the intersection of autonomy, mission planning, and command-and-control
vehicle-side autonomy and topside mission systems
, helping define how Sea Dart vehicles plan, execute, communicate, and adapt across a range of operational scenarios. This is product development, not one-off prototype work. Your contributions will shape reusable frameworks, shared mission software, and platform capabilities that persist across programs and customers.

You’ll be part of a team that values engineering ownership
, fast iteration with discipline
, and building software that performs when deployed, not just when demonstrated.

• You’ll work on a Leidos-owned UUV product line
  , not just a single program.
• Your software will define how missions are planned and executed underwater.
• You’ll bridge autonomy and mission systems
  , influencing vehicle behavior end-to-end.
• You’ll build reusable, long-lived capability
  , not throwaway prototypes.
• You’ll seeadería work deployed, tested, refined, and fielded.

If you want to help define the software backbone of a modern undersea autonomy product line, this is theビー role.

• Design and implement autonomy and mission-planning software in modern C++, supporting Sea Dart UUVs executing complex missions with minimal human intervention.
• Develop mission planning and orchestration logic that converts operator intent into executable behaviors for autonomous undersea vehicles.
• Build and evolve command-and-control capabilities that monitor mission execution, manage vehicle state, and adapt plans across intermittent or degraded communication links.
• Contribute directly to vehicle-side autonomy frameworks
  , including behaviors, state machines, planners, and mission execution logic.
• Engineer software for isolation
  , accounting for lack of GPS, unreliable RF/acoustic communications, latency, and partial situational awareness.
• Define and maintain clean software interfaces between mission systems, autonomy components, and vehicle control layers across the Sea Dart product line.
• Support integration, test réalisateur debachine real interactions between autonomy software, mission planning tools, and deployed vehicles.
• Participate in product-level architecture decisions
  , ensuring Sea Dart software remains modular, scalable, and reusable across programs.
• Collaborate across disciplines
  , including autonomy, RF/comms, systems, hardware, and test engineers, to deliver cohesive product capability.
• Help mature the Sea Dart software ecosystem
  , improving tooling, workflows, and technical standards as the product line evolves.

• Education & Experience - Bachelor's degree in Computer Science, Software Engineering, or related field with 8-12 years of experience, or a Master's degree with 6-10 years of experience.
• Security Eligibility - A ability to obtain and maintain a U.S. Secret clearance
  .
• Primary Software Expertise - Strong proficiency in modern C++ development on Linux, with solid fundamentals in performance, memory management, concurrency, and code quality.
• Autonomy & Mission Systems Awareness -
• Distributed & Degraded Systems Thinking - Ability to design software that coordinates across components, tolerates partial failure, and operates under intermittent communications.
• бүгүн Python for Support & Tooling -
  
  Working experience with Python for scripting, tooling, testing, or integration كمية؟ tasks.
• Development Environments - Experience developing and deploying software in Linux environments using containers or virtualized systems (e.g., Docker, VMware).
• Experience working in iterative development environments with tools such as Jira, Confluence, Bitbucket, or similar.
• Communication & Collaboration - Ability to communicate clearly across engineering…
