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.

At the heart of Defining Possible is our commitment to missions. In rapidly changing global security environments, Northrop Grumman brings informed insights and secure technological solutions to enable strategic objectives. We're looking for innovators who can help us keep building on our wide portfolio of secure, affordable, integrated, and multi-domain systems and technologies that fuel those missions. By joining in our shared mission, we will support your mission of expanding your personal network and developing skills, whether you are new to the field or an industry thought leader.

At Northrop Grumman, you will have the resources, support, and team to do some of the best work of your career. Northrop Grumman's Corporate Chief Information & Digital Office (CIDO) is seeking a Principal Systems Engineer / Senior Principal Systems Engineer to support the Office of the Chief Engineer's IT Solutions team. The selected candidate will work as an IT Systems Engineer serving as a senior technical lead within the Systems Engineering & Architecture IPT and will be required to work on-site, full-time at our Melbourne, FL campus - this is NOT a remote work opportunity.

This individual will be responsible for architecting and delivering the Digital Engineering Ecosystem (DEE) - the integrated IT backbone that connects authoritative sources of truth, digital models, program data, and engineering tools across program lifecycle. The DEE lead operates at the intersection of enterprise IT, systems engineering, digital transformation, AI/ML integration, and government compliance. This engineer works across every phase of the product development lifecycle - concept, design, integration, verification, and sustainment - while serving as the primary technical interface to the program's government customer and to Systems Engineering IPT leadership.

This position offers the opportunity to architect, lead, and deliver secure, modern IT infrastructure for a government-grade customer - driving digital engineering strategy, AI-enabled automation, and data-driven decision-making from the ground up. This is not an entry-level role, a principal systems engineer is expected to independently lead technical work streams, mentor junior engineers, interface directly with government customers and program leadership, and make architectural decisions that shape the DEE for the life of the program.

Candidates with a foundation in artificial intelligence, machine learning integration, and intelligent automation will be especially competitive. If you are technically sharp, mission-focused, and ready to own outcomes - we want to hear from you.

Key Responsibilities:

DEE Architecture & Leadership
* Lead the design, development, and governance of the Looking Glass Digital Engineering Ecosystem (DEE) architecture end-to-end.

* Define and enforce the DEE framework that connects Program Authoritative Sources of Truth (ASoTs) - data, models, documents - across all stakeholder communities.

* Identify and integrate AI-enabled capabilities into the DEE where appropriate - including intelligent data pipelines, automated anomaly detection, and predictive analytics on program data.

* Ensure DEE architecture enables digital engineering and sustainment access throughout the full program lifecycle.

* Own architectural decisions and produce authoritative architecture artifacts:
Con Ops, SRDs, SoS architecture diagrams, interface documents, and SoS-level agreements. Systems Engineering & MBSE
* Lead or co-lead the IT technical baseline; develop and deliver the Systems Engineering Management Plan (SEMP).

* Apply Model-Based Systems Engineering (MBSE) using Cameo, Orbus, or equivalent - producing models that are consumable by both engineering and government stakeholders.

* Drive requirements definition, allocation, traceability, and management throughout the program lifecycle using DOORS and/or RTM.

* Lead and prepare program review artifacts for SRR, PDR, CDR, SVR, and TRR; present to IPT and government customer.

* Conduct trade studies,…
