Guidance, Navigation, and Control Engineer

Los Angeles, California

ABL's Guidance, Navigation, and Control (GNC) Engineers get the customer satellite delivered to the right spot every time.

Solid GNC Engineers know not only how to steer the launch vehicle on its way to orbit, but also how to work across teams to pull all of the systems together that make it possible.

Responsibilities

Perform and lead the GNC system development, implementation, integration and testing

  • Gather, define, and document requirements to support mission and/or trajectory
  • Develop GNC algorithms, models and software

Develop, analyze and review data to validate and verify system meets specifications and design requirements

  • ‍Perform modeling and simulation tasks to validate system design and performance
  • Perform GNC system integration, checkout and troubleshooting of anomalies
  • Perform and direct test planning, development of test procedures and test execution

Develop sensor and support Avionics systems requirements

  • ‍Support critical sensor (e.g. IMU) system engineering, integration and test
  • Support critical controller (e.g. Thrust Vector Control Actuators, Throttle Valves) system engineering, integration and test

Mission specific analysis for customer launch and in support of business development

  • ‍Perform "Hardware in the Loop" (HITL) testing/simulation prior to launch on both testbed and integrated launch vehicle
Near Term Responsibilities

During ABL's early phases, the GNC engineer will be responsible for a broad scope, initial high level areas of responsibility may include:

Stand up development integrated test bed

  • ‍Work with Avionics, Software and hardware teams in HITL environment to develop transitions and commands
  • Develop codes needed to "fly" the rocket in a simulation environment in support of HITL testing

Work with design engineers to iterate between structural and GNC limits

  • ‍Perform trajectory analysis in coordination with structures design team to enable loads analysis and design optimization for primary structure capability
  • Design for loads alleviation through trajectory and loads development/understanding

Develop GNC algorithms, models and software

  • ‍Create software implementation guide and coordinate with software engineering team to write high level flight software responsible for flying vehicle and deploying payload to intended orbit
Medium-Term Growth Path

As ABL matures and after the GNC system development is well underway, the GNC engineer will have an opportunity to build out a team and lead a group. That is dependent of course on the interest by the GNC engineer and demonstrated leadership.

Basic Qualifications

B.S. from an accredited university

4+ years experience in the development of aircraft, missile, spacecraft or similar vehicle Navigation systems or GNC systems

Preferred Skills and Experience

Demonstrated skills in modeling, simulation, and analysis software such as MATLAB/Simulink and experience in at least one or more high-level programming languages (e.g. C, C++, or FORTRAN)

Proficiency in trajectory planning/design and optimization algorithms or tools (e.g. POST2)

Day of launch or on-orbit systems support including launch limits and loads/GNC capabilities evaluation

Demonstrated leadership of or within a small project team either in current role or during project based team in school

Additional Requirements

The GNC engineer must be willing to travel to the launch site to support vehicle checkouts such as HITL prior to launch, especially on first-article products.

What We Look For

Beyond technical prowess, ABL focuses on the following candidate characteristics. Tangible examples are the best way to highlight these during the evaluation process.

1. Critical thinking: ABL engineers understand the "why" behind all design decisions, operational events and test outcomes.  

2. Ability to deal with ambiguity: there is no roadmap and ABL engineers must be comfortable defining their own pathway to an objective. 

3. End-to-end ownership: projects are delivered fully complete and ready for flight; there is no one to pick up the slack of partially complete work.
