RELOCATION ASSISTANCE: Relocation assistance may be available CLEARANCE REQUIRED FOR START: Yes CLEARANCE TYPE: Top Secret TRAVEL: Yes, 10% of the Time Description 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. Expand your horizons, advance your career, and contribute to a secure future for generations. Northrop Grumman’s Space Sector invites you to bring your pioneering spirit to our collaborative teams. As a Guidance, Navigation, and Control (GNC) Engineer Level 3 supporting our Space team, this role can be based at either our Dulles, VA, or Gilbert, AZ locations. On our team, you’ll be a linchpin in missions of paramount importance, defining the art of the possible from day one.   This role is 100% onsite and cannot accommodate telecommute work .    This position description does not represent a current opening but may be used to identify candidates with skills and experience for positions within Northrop Grumman that frequently become available. Candidates who express an interest may be considered for future positions at Northrop Grumman. The GNC team designs, builds, and tests 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. Job Responsibilities In this role you will: • Design, analyze, and tune spacecraft attitude and position control loops using time and frequency domain techniques • Design and analyze relative guidance solutions for Rendezvous and Proximity Operations (RPO) • Design, analyze, and tune sequential filters (e.g. Kalman filters) for attitude determination and relative navigation • 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 position 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 This role is 100% onsite and can
