GNC Engineer Seen this week

Reflect Orbital · Hawthorne HQ · Space Systems · first seen 2026-07-16

About the Role

As a GNC Engineer, you will enable prediction of in-orbit performance for a novel space vehicle. Your work spans vehicle-level dynamics modeling, orbital dynamics propagation, and controller design for flight-ready avionics. You will bring full-stack GNC development capability.

Responsibilities

  • Develop and own the 6-DOF simulation for understanding vehicle attitude, station-keeping, and orbital performance
  • Design and implement controllers on hardware going to space by writing software yourself
  • Use simulation to constrain and inform ADCS design
  • Work closely with avionics engineers to ensure performant, reliable attitude determination and control
  • Analyze orbits, constellation designs, trajectories, and attitude motion profiles to maximize vehicle service performance
  • Contribute to high-level vehicle architecture decisions
  • Support prototyping and implement controllers on prototype hardware
  • Develop creative solutions to novel problems in precisely positioning reflected sunlight from space

Ideal Qualifications

  • 4-6 years of professional GNC engineering experience, ideally on spacecraft or other dynamically controlled vehicles
  • Clear prior technical ownership of functioning vehicle controllers and simulation (e.g. designed and simulated GNC for a specific vehicle)
  • Experience building simulation environments from scratch and familiarity with best practices
  • Experience implementing attitude control and/or estimation algorithms on spacecraft
  • Experience with verification and validation of GNC flight software in integrated environments, using 6-DOF simulation and HITL testing

We are interested in exceptional individuals and may consider candidates who do not meet 100% of qualifications. We carve out unique roles for unconventional people we are excited to work with.

Benefits

  • Medical, dental, and vision coverage; Reflect covers 100% of each base-policy
  • Access to HSA, FSA, and 401K
  • Unlimited paid time off, two weeks per year encouraged
  • Daily healthy lunches provided
