## 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.

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.

Expand your horizons, advance your career, and contribute to a secure future for generations. Northrop Grumman’s Space Sector is recruiting junior and mid-level engineers with backgrounds in Guidance, Navigation, and Controls (GNC) Engineering to support our team in Dulles, VA, Gilbert & Chandler AZ, and Redondo Beach, AZ.

This position is 100% on-site and cannot accommodate telecommute work.

This position is contingent upon the candidate obtaining final clearances and program access(es) within a reasonable period of time as determined by the company.

Key skills we are seeking:

- 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
- 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)
- Develop and validate high-fidelity 3 DOF/6 DOF models and simulations of attitude, ephemeris, and line-of-sight dynamics.
- Design, implement, and verify GNC algorithms, including trackers, filters, and controllers.
- Build, test, and integrate software and simulation tools that enable reliable space vehicle and payload GNC throughout flight operations
- Design, develop, implement, verify, and test high-quality software and simulation toolchains
- Work on a 6-degree-of-freedom (6DoF) simulation to design and test missile flight code
- Work with 6DoF simulation models to evaluate system performance
- Experience with missile flight dynamics, autopilot and guidance design, and implementation into missile flight code
- Experience with various trajectory optimization software and tools
- 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

Basic Qualifications for Levels 1-4:

- Bachelor’s degree with 1 year of professional experience (Level 1)
- Bachelor’s degree with 2 years of professional experience, or Master’s degree with 1 year (Level 2)
- Bachelor’s degree with 5 years of professional experience, or Master’s degree with 3 years, or PhD with 1 year (Level 3)
- Bachelor’s degree with 8 years of professional experience, or Master’s degree with 6 years, or PhD with 4 years (Level 4)
- Requires an active U.S. Government Secret or Top Secret security clearance at the time of application, current and within scope
- Directly related Guidance, Navigation, and Control (GNC) experience

Preferred Qualifications:

- Master’s or PhD in a relevant engineering discipline
- Top Secret clearance
- Experience designing and implementing attitude-control or state-estimation algorithms
- Experience performing actuator/sensor sizing and selection
- Experience with modeling, simulation, and verification/validation of 3‑DOF/6‑DOF GNC systems
- Ability to conduct complex kinematics and dynamics analyses and to contribute to early-stage (clean-sheet) space vehicle and payload conceptual design
- Experience with software and hardware-in-the-loop testing
- Experience with version control tools such as SVN or Git
- Experience implementing spacecraft GNC algorithms on embedded systems
- Strong technical fundamentals in the areas of spacecraft attitude and orbit dynamics, navigation filtering and/or control systems design
- Experience with on-orbit space vehicle operations, commanding, debugging, and use of flight telemetry to track performance metrics
- Experience with Rendezvous and Proximity Operations (RPO) algorithms, practices and planning strategies
- Experience with performing spacecraft GNC design, analysis, Hardware (HW) and Integration & Test (I&T), or flight operations.
- Excellent analytical and problem-solving abilities
