About The Position

Varda is hiring a Senior Guidance, Navigation, and Controls (GNC) Engineer to own the full life cycle of GNC development, from design through unit testing, hardware-in-the-loop testing, on-vehicle functionality, and flight testing. The role performs system analyses, including simulations and Monte Carlo analyses, to satisfy specifications and requirements and inform system-level architectural and business decisions. The engineer will contribute to Varda’s in-house aerospace simulation and test framework and develop and maintain design descriptions and supporting documentation. The role covers end-to-end GNC subsystem execution, from initial analysis and design through vehicle integration, mission planning, flight, and support of on-orbit and reentry mission operations. It is an on-site role in El Segundo, California. The stated annual salary range is $169,067–$216,031. The role is eligible for long-term incentives in the form of stock options and/or long-term cash awards. Because employees have access to export-controlled items, Varda’s policy is to hire U.S. persons who may access the technology without an export license.

Requirements

B.S. degree in aerospace, mechanical, or electrical engineering, physics, or a related field.
At least 5 years of proven experience, or a Ph.D. with at least 3 years of relevant experience.
Demonstrated knowledge designing, modeling, testing, and flying aerospace guidance, navigation, and control systems.
Highly adept software and model development skills, particularly in C++ and Python.
Understanding of orbital mechanics, modeling and simulation, and software development.
Experience anchoring or fitting first-principles models to test data or high-fidelity external simulations.
Proven systems-engineering and configuration-management skills.
Excellent written and verbal communication skills.
Must qualify as a U.S. person under the stated export-control access policy.

Perform trajectory design, optimization, and dispersion analysis for space-capsule reentry.
Develop six-degree-of-freedom vehicle simulations using C++, Python, and MATLAB/Simulink.
Run Monte Carlo analyses to characterize performance of new vehicle and mission capabilities.
Integrate and test GNC sensors, actuators, and software in a hardware-in-the-loop environment.
Design and implement ground tooling for fully automated maneuver responsibility and maneuver-scheduling decisions.
Monitor on-orbit system performance and troubleshoot where necessary.
Coordinate with other spacecraft operators, third-party agencies, and the U.S. government.
Perform GNC system analyses and support system-level architectural and business decisions.
Contribute to Varda’s in-house aerospace simulation and test framework and maintain design descriptions and supporting documentation.
Support GNC execution from initial analysis and design through vehicle integration, mission planning, flight, and on-orbit and reentry mission operations.
