Senior Software Engineer, Autonomy Actions Sustaining
Confirmed on the employer's own hiring board on Oct 20, 2026. First seen by Alion on Sep 29, 2026. Motional scores B on the Alion truth index.
Mission Summary:
We are looking for a Senior Software Engineer to join the Planning, Motion, and Controls Team to develop and maintain simulation and analysis tools that allow for faster development of the autonomy stack behavior and for automated root cause analysis. This is an exciting opportunity for someone who is looking to make a significant impact in the development and improvement of autonomous driving technology. If you are a self-motivated individual with a strong background in software development and a passion for creating advanced tools, we encourage you to apply for this role.
What you'll be doing:
- Core Tech Stack: C++ (for native tool development and high-performance bindings with the autonomous driving stack), Python (for scripting and backend tooling). Design and develop efficient and user-friendly tools to support development of autonomy technology
- Parameter Overrides & Local Reruns: Developing local or cloud-based execution runners that allow engineers to modify config files/parameters (e.g., cost weights, distance thresholds, safety margins) and codebase and rerun the autonomy stack against a recorded log to observe behavioral changes instantly.
- Behavior Step-Through & Re-Simulation: Building GUI debuggers and web-based or native 2D/3D visualizers that ingest logged perception, prediction, and planning frames, letting developers pause, step forward/backward frame-by-frame, and inspect decision logic.
- Collaborate with the planning and controls engineers to understand their requirements of simulation and analysis tools
- Continuously improve and optimize the simulation and analysis tools to enhance their performance and functionality
- Contribute to the success of the Motional autonomous driving technology by actively listening to the pain points of the Autonomy engineers and developing robust solutions
What we're looking for:
- Bachelor's or Master’s degree in Computer Science, Software Engineering, or a related field.
- Minimum of 5 years of experience in Software development and Testing, preferably in the automotive or gaming industry.
- Strong proficiency in programming languages such as C++, with a focus on building high-performance and resilient systems.
- Comfortable navigating and contributing to large, complex codebases where modularity and documentation are key.
- Passionate about a driverless future and understand the high stakes of deploying software that interacts with the physical world.
Bonus points (not required):
- Experience with game engine development
- Experience with planning and control systems
- Experience with performance optimization with high throughput data
- Experience with Qt development
Motional is a driverless technology company making autonomous vehicles a safe, reliable, and accessible reality. We’re driven by something more.
Our journey is always people first.
We aren't just developing driverless cars; we're creating safer roadways, more equitable transportation options, and making our communities better places to live, work, and connect. Our team is made up of engineers, researchers, innovators, dreamers and doers, who are creating a technology with the potential to transform the way we move.
Higher purpose, greater impact.
We’re creating first-of-its-kind technology that will transform transportation. To do so successfully, we must design for everyone in our cities and on our roads. We believe in building a great place to work through a progressive, global culture that is diverse, inclusive, and ensures people feel valued at every level of the organization. Diversity helps us to see the world differently; it’s not only good for our business, it’s the right thing to do.
Scale up, not starting up.
Our team is behind some of the industry's largest leaps forward, including the first fully-autonomous cross-country drive in the U.S, the launch of the world's first robotaxi pilot, and operation of the world's longest-standing public robotaxi fleet. We’re driven to scale; we’re moving towards commercialization of our technology, and we need team members who are ready to embrace change and challenges.
