Autonomous Simulation Software Engineer

Leidos; Lynnwood (WA); On-site; USD 120,000 - 170,000; Full time

Job summary

Leidos is seeking an Autonomous Simulation Software Engineer to build the software and simulation infrastructure behind next-generation uncrewed underwater vehicles and maritime autonomous systems.

This hands-on role focuses on modeling vehicles, sensors, environments, and mission behaviors within the MAGMA-based Simulation Framework, delivering reusable capabilities that engineers can exercise before hardware testing.

Qualifications

• Hands-on software engineering role building simulators and reusable frameworks.
• Develop models for vehicles, sensors, environments, and mission behaviors.
• Support MAGMA-based Simulation Framework to reuse capabilities across programs.

Responsibilities

• Develop software that models vehicles, sensors, environments, interfaces, faults, and behaviors.
• Provide reusable simulation capabilities across vehicles, missions, and programs.

Description

Build the simulated worlds where autonomous UUVs learn, fail, improve, and prove they’re ready for the real one.

Leidos is looking for an Autonomous Simulation Software Engineer to build the software and simulation infrastructure behind next-generation uncrewed underwater vehicles and maritime autonomous systems.

Autonomous systems operating underwater face a uniquely unforgiving environment: limited communications, uncertain navigation, imperfect sensors, complex vehicle dynamics, and missions where the software must make good decisions without waiting for help. We need simulation environments capable of reproducing those challenges with enough fidelity to develop, integrate, test, and ultimately trust the autonomy that operates in them.

This is a hands‑on software engineering role for someone who enjoys building simulators, modeling complex systems, and creating reusable simulation frameworks. You'll develop software that models vehicles, sensors, environments, interfaces, faults, and behaviors—giving engineers the ability to exercise mission software repeatedly before putting a vehicle in the water.

You'll directly support a growing program while also helping evolve and expand our MAGMA-based Simulation Framework, creating simulation capabilities that can be reused across vehicles, missions, and programs.

We already have engineers who know autonomy and engineers who have built simulation capability out of necessity. We're looking for someone who brings simulation engineering as a discipline—and who wants to help us take that capability much further.

Why This Role Is Different

• You’ll build simulations that engineers actually depend on, not visualization demos.
• You’ll model real systems and real failure modes, including vehicles, sensors, environments, interfaces, and mission behaviors.
• You’ll help increase simulation fidelity, closing the gap between what happens in software
