At Northrop Grumman, our employees have incredible opportunities to work on revolutionary systems that impact people’s lives around the world today, and for generations to come. Our pioneering and inventive spirit has enabled us to be at the forefront of many technological advancements in our nation’s history – from the first flight across the Atlantic Ocean, to stealth bombers, to landing on the moon. We look for people who have bold new ideas, courage and a pioneering spirit to join forces to invent the future, and have fun along the way. Our culture thrives on intellectual curiosity, cognitive diversity and bringing your whole self to work — and we have an insatiable drive to do what others think is impossible. Our employees are not only part of history, they’re making history.

Northrop Grumman’s Space System is seeking a Spacecraft Guidance, Navigation, and Control (GNC) engineer, located in Dulles, Virginia or Gilbert, Arizona.

GNC is designing, building, testing spacecraft subsystems for a mix of DoD, NASA, and commercial customers. We are leaders in innovative solutions to the rapidly growing/evolving fields of space based autonomous rendezvous and docking and rapid design/production of small satellites. We are seeking a highly-talented and ambitious Engineer to take responsibility for the GNC solutions for the groundbreaking Mission Robotic Vehicle & Mission Extension Pod program which involves enhanced capabilities such as mission life extension services, in-orbit repair, augmentation, assembly, detailed inspection and relocation of client spacecraft.

The spacecraft GNC analysis engineer will work within the GNC subsystem team and is expected to:

Design, analyze, and tune spacecraft attitude and position control loops using time and frequency domain techniques
Design, analyze, and tune sequential filters (e.g. Kalman filters) for attitude determination and relative navigation
Design, develop, test and verify flight algorithms for the GNC subsystem and support flight software qualification testing
Analyze and test the spacecraft GNC subsystem performance using simulations and other analytic tools
Perform analysis to support early design phase concept development including actuator sizing and placement, sensor selection and placement, attitude and positon guidance, rendezvous, proximity operations and docking analyses, and predicted performance assessments
Develop simulation models for sensors (e.g. star tracker, rate gyro, accelerometer, GPS, magnetometer, sun sensors), actuators (e.g. reaction wheel, torque bar, thruster, CMG), system dynamics (e.g. rigid body, multi-body, orbit mechanics, flexible models, propellant slosh), and the space environment (e.g. atmospheric, solar radiation pressure, third-body gravity, geopotential)
Communication is a key element of your role and all GNC engineers are expected to:
Apply engineering principles, industry standards, company process, and knowledge of vehicle dynamics, aerodynamics, propulsion, classical/modern control, and estimation theory to perform tasks to advanced program/project goals
Document designs, analysis, and test results and create presentation materials
Present designs, analysis, and test results to internal and external customers
Work well within small- to medium-sized groups
