Job description

TSC is seeking a remote based Guidance, Navigation, Controls (GNC) Engineer that will design, integrate, test, and deliver flight control systems or mission-critical onboard software for unmanned aerial systems (UAS). The ideal candidate will have experience in UAS Guidance, Navigation, & Control (GNC) utilizing inertial navigation, vision, collision avoidance, commercial autopilots, redundancy management and path planning architecture. The GNC Engineer will participate hands-on in the full software life cycle, from concept through implementation, integration to flight test and operational release. This position in onsite based in Crystal City, VA with up to 25% travel required.
As a GNC Engineer you can anticipate some of your day-to-day responsibilities to include:
  • Work on a team to develop, modify and tune guidance and control systems for fixed wing aircraft
  • Work on a team to develop, modify and tune navigation systems based on sensor fusion of 6-DOF IMU, magnetometer, GNSS, pressure and ranging sensors.
  • Work on a team to develop and modify 6-DOF and Hardware-in-the-Loop simulation environments
  • Simulation, analysis, control, and testing on 6 degree-of-freedom (6-DOF) motion platform for development and validation of autonomous UAS.
  • Work on a team to design and develop flight or mission-critical onboard software for unmanned systems
  • Aid development for unmanned aerospace includes guidance, navigation & control, mission sequencing, payload control, redundancy and contingency management, uplink and downlink packet encoding and decoding, converting between different serial protocols, hardware-in-the-loop simulation, ground-based GUIs, and aircraft subsystem control (i.e., payload, electrical systems)
  • Embedded Software development (C/C++, Python, shell scripts)

Writing/modifying software to adjust flight behaviors:
  • Use development tools such as: JIRA, git, C/C++, CMake, Linux, MATLAB
  • Collaborate with a multi-disciplinary software team on large, multi-language projects
  • Participating in code reviews, Flight Testing, and Customer Presentations
  • Bench test, Hardware-in-the-loop, and field testing of UAS platforms
  • Local, interstate, and international travel to support field testing and customer demonstrations. Expected travel is ~10-25%.
  • Collaborate with other engineering disciplines (Systems, Software, Mechanical, Electrical) in planning, design and development of systems to ensure software and hardware performance and compatibility
  • Design software architecture, interfaces, and gateways for communication with external Autonomy software services. Implement functionality using a model-based approach.
  • Software verification and validation including writing Test Cases and Test Procedures
  • Develop, implement, and document data and software application test plans to validate project deliverables meet quality standards
  • Oversee and support processes and procedures for existing data and reporting activities to support internal and external customer deliverables.
  • Examples of specific deliverables include but are not limited to: recurring reports and analyses; data validation and documentation
  • Interface and derive solutions in coordination with hardware design teams

Required Qualifications
  • BS degree in Mechanical, Electrical, Computer, Aerospace, Controls engineering or other relevant discipline, plus at minimum 5 years of experience in a professional environment developing MATLAB / Simulink control systems with auto code experience; or MS in Controls or Aerospace Engineering plus 2 years' experience. Embedded code experience preferred.
  • US Citizenship and the ability to obtain and maintain a DoD Security Clearance
  • Experience in developing physics based 6 DOF simulations, motion platforms.
  • Experience developing with: Gazebo or similar simulation tools, MatlabMATLAB/Simulink, C, C++, Python
