Job description

NDI Engineering is seeking a Systems Engineer to serve as a technical lead for the Naval Surface Warfare Center (NSWCPD). This role is pivotal in transitioning complex Submarine Hull, Mechanical, and Electrical (HM&E) systems from document-based engineering to a Model Based Engineering (MBSE) environment.

You will lead the development and maintenance of enterprise-level architectures, ensuring that safety, cybersecurity, and mission requirements are digitally integrated across the full system lifecycle—from initial design through sustainment.

Role Overview

The Systems Engineer will serve as a technical MBSE lead supporting system development, analysis, risk management, requirements management and validation, delivery certification and life cycle support.

The role focuses on the application of system modeling ensuring architectural coherence, safety, cybersecurity, and mission requirements are integrated across the system lifecycle.

Position involves using digital models to manage and integrate system engineering activities, ensuring traceability, compliance, and performance across the product lifecycle and blends systems engineering, modeling, and collaboration across technical disciplines.

The role is an in‑person in the Philadelphia area, supporting in‑service and new submarine systems at NSWCPD. The position is part of NDI Engineering’s mission to enable design, test and evaluation, acquisition, engineering, systems integration, and life‑cycle savings with cybersecurity and logistics integration.

Compensation

$95,500- $130,000/year.

Key Responsibilities

• Lead enterprise‑level system architecture development and maintenance including defining modeling conventions, architectural frameworks, and reusable patterns for the program.
• Create and maintain subsystem and system models using SysML or other MBSE standards, representing components, functions, interfaces, and behaviors.
• Support system integration, verification, validation, and certification of hardware and software.
• Work with system, software, hardware, integration, and test engineers to resolve issues and ensure full traceability from requirements to architecture, behavior, interfaces, and verification.
• Apply MBSE across the full system lifecycle, including requirements management, traceability, analysis, and verification.
• Collaborate with systems, software, safety, and cybersecurity Subject Matter Experts (SMEs) to align functions, safety constraints, and cybersecurity considerations.
• Produce architecture views and model‑based artifacts for major design reviews (Peer Reviews, Requirements Reviews, Configuration Control Boards, Test Readiness Reviews, Preliminary and Critical Design Reviews (PDR, CDR)).
• Ability to translate complex technical information into clear, concise executive-level summaries.
• Experience working in DoD environments or complex system‑of‑systems programs

Qualifications

• Education: Bachelor of Science required. Master’s degree preferred. Degree(s) in a field such as: Systems Engineering, Mechanical Engineering, Computer Engineering, Software Engineering, Industrial Engineering or a related field
• Experience & Work Eligibility 5+ years of systems engineering and MBSE experience is required
• Strong systems engineering background with MBSE methodology experience.
• Familiarity with DoD processes and Risk Management Framework (RMF) accreditation.
• Ability to work in multidisciplinary teams and understand both hardware and software systems.
• Proficiency in MBSE tools (I.E. SysML, UAF, Cameo Systems Modeler, CATIA Magic Draw, Teamwork Cloud, Jira, DOORs).
• Security Clearance Requirement: Must be able to obtain and maintain Active DoD Secret Clearance.
• Strong cross‑functional team leadership and communication skills.
