Summary

Develop deterministic C++ software for embedded aircraft systems, integrating with sensors and control systems to automate flight operations. The role involves driving requirements, implementing unit tests, and collaborating with flight hardware and testing teams in a safety-critical environment.

Job description

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 Flight Software Engineer at Reliable Robotics, you will automate the operation of highly complex aircraft systems. Our Flight Software teams are deeply involved in all aspects of the development and certification of the Reliable Robotics autonomy stack, and play a central role in bringing our aircraft to life.

Responsibilities

In your role as Flight Software Engineer, you will develop highly deterministic C++ software in a bare metal environment that works with sensors & control systems, robustly handles system faults, and integrates with other vehicle subsystems. You'll drive requirements and implement excellent unit tests. You'll also have the opportunity to work directly with flight hardware in the lab and on the plane, plan flight testing, and watch your code fly an aircraft.

Basic Success Criteria

  • Bachelor's Degree in Computer Science, Aerospace or equivalent experience
  • 7+ years of professional experience with C or C++
  • Professional experience developing software for embedded or high performance applications
  • Ability to work in a self-directed manner in a fast-paced environment

Preferred Criteria

  • Thorough understanding of computer architecture, operating systems and networking
  • Experience with DO-178C
  • Experience developing software for safety critical applications
  • Excellent written and verbal communication skills

Flight Software links together the mechanical, avionics, algorithmic, and embedded worlds to actually make the airplane fly. The core nature of the role offers the opportunity to interact with teams and components across the entire automated aircraft and to specialize in the areas most exciting to you.

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).
