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 GNC Engineer/Technical Lead Level 5 focused on Navigation Modeling, Analysis and Simulation located in Chandler, Arizona, you’ll be a linchpin in missions of paramount importance, defining the art of the possible from day one. This position is 100% onsite and cannot accommodate telecommute work.

In this role, you will serve as the technical lead for navigation modeling, analysis, simulation, and algorithm development supporting a full range of launch vehicle products including space launch, targets, interceptors, advanced weapons, and missile defense applications.

You will provide technical direction for inertial, satellite-based, and integrated navigation solutions; lead performance assessment in demanding environments including low-altitude flight, high-dynamic engagements, exo-atmospheric regimes, and GPS-degraded or denied conditions; and mentor engineers across the team while partnering closely with functional management, systems, software, and program leadership.

This position will work a 9/80 schedule, with every other Friday off.

In this job, you will

Lead the technical direction, architecture, modeling, simulation, analysis, and verification of navigation solutions for targets, space launch, advanced weapons, tactical strike, interceptor, and missile defense applications.
Own navigation performance assessment across diverse mission environments, including low-altitude flight, high-speed and high-dynamic engagements, glide phase intercept scenarios, space and exo-atmospheric missions, and degraded or denied GPS conditions.
Lead development and evaluation of inertial, GPS/GNSS, and integrated multi-sensor navigation approaches.
Guide estimation and sensor fusion algorithm development, including Kalman filter design, tuning, covariance analysis, and performance characterization.
Lead sensor performance assessments for IMUs, GPS receivers, radar altimeters, and other aiding sources as applicable.
Translate program and customer requirements into navigation architectures, error budgets, analysis products, and verification approaches.
Drive technical trade studies, risk assessments, and mitigation strategies related to navigation performance, robustness, and implementation.
Partner with software, systems engineering, mission analysis, and integration teams to ensure successful integration of navigation capabilities into flight software and simulation environments.
Review, mentor, and guide the technical work of other navigation and GNC engineers.
Communicate technical approaches, risks, and results to engineering teams, chief engineers, program leadership, and customers.
Support proposal, capture, and IRAD efforts through technical planning, basis-of-estimate input, and customer engagement as needed.
Other duties as assigned.

If this job description reads like it was written specifically for you, consider joining our team!

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.

Basic Qualifications

Bachelor’s degree in a STEM discipline with 12 years of related experience, or Master’s degree in a STEM discipline with 10 years of related experience, or PhD with 8 years of related experience. Will consider an additional 4+ years of experience in lieu of degree.
Significant experience with inertial, satellite-based, and integrated navigation systems.
Experience in navigation modeling, simulation, analysis, and/or algorithm development for flight systems.
Demonstrated technical leadership across multidisciplinary engineering teams.
Experience defining technical approaches, decomposing requirements, conducting trade studies, and driving verification and validation activities.
Ability to operate independently, lead complex technical efforts, and mentor other engineers.
Must have the ability to obtain and maintain a U.S. Government Secret security clearance

Preferred Qualifications

Active DoD Secret Security Clearance or higher.
Experience with C++, MATLAB, Simulink, and Python.
Experience with Linux.
Experience with IMUs, GPS receivers, radar altimeters, and related navigation sensors.
Experience with Kalman filters, navigation algorithms, sensor fusion, and simulation-based performance analysis.
Experience supporting advanced weapons, tactical strike systems, interceptor programs, missile defense applications, or space-based flight systems.
Experience with navigation in high-dynamic, exo-atmospheric, GPS-contested, or GPS-denied environments.
Experience serving as a technical lead or subject matter expert for navigation or GNC efforts.
Experience supporting design reviews, verification planning, HWIL/SIL environments, and flight test integration.
Strong written and verbal communication skills, including direct interaction with customers and senior technical leadership.
