The listing

We're building safety-enhancing technology for aviation that will save lives. Automated aviation systems will enable a future where air transportation is safer, more convenient and fundamentally transformative to the way goods — and eventually people — move around the planet. We are a team of mission-driven engineers with experience across aerospace, robotics and self-driving cars working to make this future a reality.

 

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.

 

Responsibilities

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.

 

Basic Success Criteria

  • 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.

 

This position requires access to information that is subject to U.S. export controls. An offer of employment will be contingent upon the applicant’s capacity to perform in compliance with U.S. export control laws.

All applicants are asked to provide documentation that legally establishes status as a U.S. person or non-U.S. person (and nationalities in the case of a non-U.S. person). Where the applicant is not a U.S. person, meaning not a (i) U.S. citizen or national, (ii) U.S. lawful permanent resident, (iii) refugee under 8 U.S.C. § 1157, or (iv) asylee under 8 U.S.C. § 1158, or not otherwise permitted to access the export-controlled technology without U.S. government authorization, the Company reserves the right not to apply for an export license for such applicants whose access to export-controlled technology or software source code requires authorization and may decline to proceed with the application process and any offer of employment on that basis.
