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 workstreams, 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: ConOps, 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, functional analysis, and market research to inform design decisions.
Architecture & Design — IT Infrastructure
Architect and implement scalable, redundant, highly available IT solutions across on-premises, co-location, and cloud environments.
Lead VDI solution architecture and deployment (Nutanix, VMware Horizon) in support of DEE endpoints.
Design and implement secure operating systems, networks, and COTS software solutions aligned to DEE requirements.
Optimize cloud resource utilization for cost and performance; lead cloud migration planning as applicable.
AI / ML & Intelligent Automation
Evaluate and recommend AI/ML tools, platforms, and frameworks appropriate for integration into the DEE — including predictive analytics, anomaly detection, and process optimization use cases.
Support the design of data pipelines and infrastructure (data lakes, model serving layers) that enable AI/ML workloads within compliant government IT boundaries.
Apply AI-assisted automation to systems engineering workflows — including requirements analysis, test coverage assessment, and configuration management anomaly detection.
Assess and document AI/ML system risks, including data governance, model explainability, and compliance with applicable DoD AI ethics guidelines (DoD AI Adoption Strategy, CDAO frameworks).
Collaborate with data scientists, software engineers, and program stakeholders to translate AI capability needs into actionable DEE infrastructure requirements.
Security, CM & Compliance
Ensure DEE architecture and all technology solutions comply with Enterprise policies, Government requirements, and cyber compliance mandates (DFARS, NIST 800-53, CMMC 2.0).
Lead or oversee the Infrastructure Configuration Control Board (CCB) process; ensure approved change management processes are followed.
Own configuration management for all DEE hardware, software, and firmware; drive patch and upgrade compliance.
Develop and maintain the Information Systems Security Plan (ISSP) for production and DEE systems.
Lead periodic risk assessments; produce documented mitigations and present findings to program leadership.
Stakeholder Engagement & IPT Leadership
Serve as the primary IT/DEE technical interface to the government customer and SE&A IPT Lead.
Drive collaboration across IT, cyber security, business management, and external vendors to ensure program milestones are met.
Interface regularly with project managers, architects, technical specialists, and site directors.
Mentor T01/T02 engineers; serve as technical consultant to IPT leads and program managers.
Communicate complex technical content — written and verbal — to both technical and non-technical stakeholders.
Documentation & Asset Management
Work with IT Asset Management (ITAM) to maintain authoritative records for all DEE-managed hardware and software.
Author and maintain SOPs, KBs, SRDs, interface documents, V&V plans, ConOps, and DR procedures.
Track and enforce backup procedures, disaster recovery plans, and patch compliance across the DEE.
This requisition may be filled at either a Principal Systems Engineer (T03) or Senior Principal Systems Engineer (T04).
Basic Qualifications for a Principal Systems Engineer (T03):
5 Years of relevant experience with a Bachelors degree in Engineering, Computer Science, or related STEM discipline; 3 Years with a Masters degree; 1 Year with a PhD.
Candidates must have a current U.S. Government Secret level security clearance (or higher) in order to be considered
1-5 years in IT Systems Engineering, Architecture, or Defense IT.
Demonstrated experience designing or contributing to a Digital Engineering Ecosystem or similar prog
