Job description

GNC ENGINEER - TOP SECRET CLEARANCE

As a guidance, navigation, and control mission design engineer, you will be responsible for designing and implementing physics-based system-of-systems simulation software, capable of capturing complex interactions between a wide variety of space vehicles, ground systems, and environments. You will design CONOPS and drive program-level requirements for large multi-vehicle missions. This is a high-impact role in which you will work across engineering groups, taking extreme ownership of critical trades and design decisions. We are looking for engineers who enjoy solving complex problems, can work effectively in a fast-paced environment, and are passionate about advancing the space industry.

RESPONSIBILITIES:

  • Build software tools and construct scenarios to perform system-of-systems performance analysis of architectures that include satellites, sensors, communications, and ground infrastructure
  • Conduct analyses and recommend designs that balance competing requirements
  • Develop 6-DOF dynamics simulation models used for GNC systems analysis and validation
  • Develop physics-based models for simulation of RF communications and sensor systems
  • Assess feasibility of various designs in support of architecture definition
  • Create a library of space and ground systems models, for inclusion in the simulation environment
  • Act as a cross-disciplinary expert, ensuring that the system can meet mission objectives
  • Communicate technical capabilities and analyses with internal stakeholders and external customers
  • Play an integral part of a small team that will continuously iterate on mission design through all phases of the program

BASIC QUALIFICATIONS:

  • Bachelor's degree in an engineering discipline or physics
  • 1+ years of professional experience with modeling and simulation
  • Software development experience in C++ or Python

PREFERRED SKILLS AND EXPERIENCE:

  • Active Top Secret, Top Secret SCI, or DOE Level Q clearance
  • Demonstrated experience with writing scalable software in a team setting
  • Strong modern software design and development skills
  • Professional programming experience in modern C++ (C++14 and above)
  • Master's degree or PhD in physics or an engineering discipline
  • Demonstrated experience in developing state estimation algorithms
  • Demonstrated experience in RF communication
  • Demonstrated experience in developing and presenting compelling analyses of complex trades
  • Ability to work effectively in a dynamic environment with changing needs and requirements
  • Ability to work independently and in a team, take initiative, and communicate effectively
  • Demonstrated experience in debugging, performance optimization, and test automation
  • Excellent communication skills, both written and verbal

ADDITIONAL REQUIREMENTS:

  • This position requires successfully obtaining and maintaining a Top Secret Security Clearance as a condition of employment. While the clearance may not be immediately necessary upon hire, we encourage you to initiate the application process promptly upon accepting this offer. Your ability to secure the necessary clearance is essential for fulfilling key responsibilities of the role. Should you be unable to obtain it, SpaceX reserves the right to modify or terminate your employment to align with operational needs.
  • Note that an active clearance may provide the opportunity for you to work on sensitive SpaceX missions. If so, you will be subject to pre-employment drug and random drug and alcohol testing.
  • Willing to work extended hours and weekends when needed

COMPENSATION AND BENEFITS:

Pay range:          
GNC Engineer/Level I: $125,000.00 - $150,000.00/per year 
GNC Engineer/Level II: $145,000.00 - $175,000.00/per year       

Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience. Those with an active clearance will receive a 10% differential, up to an additional $20,000 annually, once officially briefed into a classified program.

Base salary is just one part of your total rewards package at SpaceX. You may also be eligible for long-term incentives, in the form of company stock, stock options, or long-term cash awards, as well as potential discretionary bonuses and the ability to purchase additional stock at a discount through an Employee Stock Purchase Plan.
