Sr. Simulation Software Engineer

As a Senior Simulation Software Engineer, you will work to shape all aspects of our simulation software stack, including framework performance, flight dynamics modeling, hardware emulation, and simulation-based test infrastructure., In your role as Senior Simulation Software Engineer, you will lead projects to develop a robust, deterministic, and scalable software simulation framework to accelerate testing of safety-critical systems. You'll work closely with stakeholders, including flight software, guidance/navigation/control, and hardware test engineers to expand our simulation system. Your work will improve the simulation's core architecture, including performance, reproducibility, and flexibility. You'll evaluate and drive key project decisions while mentoring team members to improve their own skills.

• Bachelor's degree in Computer Science, Mathematics, Aerospace Engineering or equivalent experience
• 5+ years industry experience in simulation systems within aviation, automotive or comparable environments
• 7+ years professional experience in object oriented C++ and Python (or other scripting languages)

Preferred Criteria

• Experience modeling aircraft dynamics
• Experience developing simulations for safety-critical / DO-178 software and hardware systems
• Experience architecting complex distributed and real-time software frameworks
• Strong technical, organizational, and problem-solving skills
• Excellent documentation and collaboration skills

As a Senior Simulation Software Engineer, you will be part of the Simulation and Test Systems team. The Simulation and Test Systems team is responsible for building the infrastructure necessary to enable the development, test, and deployment of our autonomous aircraft software. You will work closely with the hardware-in-the-loop test environments, high-fidelity physics simulation stack, and cloud-based Monte-Carlo infrastructure to enable the millions of flight equivalent hours necessary to certify our aviation products. These systems provide fast and accurate feedback on the behavior of our system through a wide variety of flight plans, environmental conditions, and system faults.

Must be willing to travel up to 10% of the time.
