Leidos
Autonomous Mission Systems Software Engineer
Leidos, Lynnwood, Washington, United States, 98037
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™ UUVserts 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 . You will work across both
vehicle-side autonomy
and
topside mission systems , helping define how Sea Dart vehicles plan dass, execute, communicate, and adapt across a range of Appeal scenarios. This ultima is product development, not one-off prototype work. Your contributions will shapeardı reusable frameworks, shared mission software pacing platform that persists across programs and pelanggan.
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.
Why This Role Is Different
You’ll/we 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 will bridge
autonomy and mission systems , influencing vehicle behavior end‑to‑end.
You will build
reusable, long‑lived capability , not throwaway prototypes.
You will see your work deployed, tested, refined, and fielded.
If you want to help define the software हिंदी of a modern undersea autonomy product line, this is the role.
Primary Responsibilities
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, and field operations , debugging 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.
Basic Qualifications
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
-money 6-10
years of experience.
Security Eligibility - Ability to obtain and maintainzaamheid 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
- Experienceменты or familiarity with autonomy concepts such as behaviors, planners, state machines, or mission execution logic.
Distributed & Degraded Systems Thinking
- Ability to design software that coordinates across components, tolerates partial failure, and operates under intermittent communications.
Python for Support & Tooling - Working experience with
Python
for scripting, tooling, testing, or integration tasks.
Development Environments
- Experience developing and deploying software in Linux environments using containers or virtualized systems (e.g., Docker, VMware).
Agile Engineering Practices
- Experience working in iterative development environments with tools such as Jira, Confluence, Bitbucket, or similar.
Communication & Collaboration
- Ability to communicate clearly across engineering disciplines and contribute constructively to technical discussions and design reviews.
Professional Integrity
- Demonstrated ownership, accountability, and respect for teammates and mission outcomes.
Preferred Qualifications
Mission Planning & Orchestration
- Hands‑on experience developing mission planners, task orchestration systems, or autonomy frameworks for robotic or distributed systems.
Autonomous Vehicle Experience
- Experience with robotic, maritime, or undersea autonomous platforms, including integration with vehicle control software.
Embedded or Edge Systems
- Familiarity with software running in contacted or embedded environments.
Polyglot Engineering
- Experience across multiple languages (Java, Python, C++, Rust, etc.) and the ability to integrate with heterogeneous software stacks.
Messaging & Interfaces
- Experience with publish/subscribe architectures, message serialization (e.g., Protocol Buffers), or distributed data models.
Product-Line Engineering
- Experience contributing to shared platforms or product line where reuse, consistency, and long‑term evolution matter.
Toolchain Familiarity
- Experience with ROS, Protocol Buffers, VS Code, SCons, or similar tooling is a strong plus.
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.
