Senior Digital Engineer

Description
SAIC is seeking a Digital Engineering Specialist - Modeling & Simulation (M&S) for HWIL and SIL Development for the US Navy's Submarine-Launched Cruise Missile-Nuclear (SLCM-N) weapon system.
In this role, the candidate will apply advanced M&S techniques and cutting-edge Digital Engineering principles to support system development, assess weapon system performance, and contribute to Verification and Validation (V&V) efforts.
This role focuses on designing and executing M&S activities for system and subsystem-level evaluations, as well as designing integrated architectures that connect physical and simulation-based systems. The selected individual will collaborate with engineers, developers, and stakeholders to refine M&S scenarios, enhance model fidelity, and ensure data-driven decision-making across hardware-integration frameworks, test platforms, and the broader Digital Engineering lifecycle.
This position requires onsite support at NSWC Crane Division in Crane, Indiana, and offers a unique opportunity to contribute to the development of critical strategic defense systems through innovation, architecture development, and collaboration.
NOTE: This position is 100% remote.
JOB RESPONSIBILITES:
Modeling & Simulation Design and Execution:

• Lead and execute M&S activities using Hardware-in-the-Loop (HWIL) and Software-in-the-Loop (SIL) methodologies, emphasizing integration within common engineering test beds to enable real-time performance evaluation and validation.
• Develop adaptable simulation environments to model complex system interactions, integrating physical hardware with virtual representations for rapid prototyping, evaluation, and refinement.
• Simulate real-world operating conditions to evaluate subsystem performance, sensor integration, and system behaviors across different lifecycle phases.
• Architect and develop cohesive Digital Engineering environments that connect physical test hardware, models, and simulations into a unified and scalable system.
• Ensure alignment between M&S frameworks, Digital Engineering principles, and broader program architecture to reduce design timelines and improve decision-making.

Architecture Development and Integration:

• Collaborate with technical teams to conceptualize, design, and develop Digital Engineering architectures that integrate physical and simulation-based systems.
• Define and manage the technical underpinnings of the digital thread, ensuring that simulation and physical testing environments remain interoperable, scalable, and adaptable to evolving program needs.
• Leverage principles from Model-Based Systems Engineering (MBSE) and Digital Twin development to build robust system-testing architectures.
• Identify and implement architectures that enhance coordination across HWIL/SIL platforms, simulation frameworks, and broader system development processes.

Subsystem and System-Level Performance Evaluations:

• Conduct M&S analyses to evaluate subsystems, system architectures, and hardware/software integration under various developmental and operational scenarios.
• Perform trade studies and parametric analyses using M&S tools to inform design decisions, assess alternatives, and enhance engineering outcomes.
• Use simulation data to verify design feasibility, identify potential deficiencies, and recommend design improvements.

Model Validation and Enhancement:

• Validate and verify M&S frameworks to ensure accuracy, credibility, and alignment with operational and developmental requirements.
• Collaborate with program stakeholders and technical teams to ensure that M&S environments build on real-world data and Digital Twin representations for accuracy and operational relevance.
• Recommend innovations and enhancements to M&S tools, frameworks, and workflows to address evolving program complexities and support next-generation HWIL/SIL capabilities.

Integration with Verification & Validation (V&V) Activities:

• Align M&S results with system Verification and Validation (V&V) processes, enabling robust design verification, functional validation, and compliance with requirements.
• Support the development of key deliverables, such as Requirements Verification Compliance Matrices (RVCMs) and system test plans using M&S-driven insights.
• Present M&S contributions during milestone reviews, including System Requirements Reviews (SRRs), Preliminary Design Reviews (PDRs), and other program reviews.

Collaboration and Stakeholder Engagement:

• Coordinate with government stakeholders, industry partners, and multidisciplinary engineering teams to define M&S objectives, requirements, and test scenarios.
• Prepare and deliver technical reports, briefings, and presentations summarizing M&S efforts, findings, and recommendations tailored for technical audiences, senior leadership, and program stakeholders.
• Provide mentorship to junior staff in developing and refining M&S skills, advancing the adoption of Digital Engineering principles, and leveraging HWIL/SIL capabilities.

Qualifications
REQUIRED EDUCATION AND EXPERIENCE:

• Bachelor's degree in systems engineering, Mechanical Engineering, Electrical Engineering, Computer Science, or a related technical field and 5 or more years of experience.
• Interim secret clearance is required to start with the ability to obtain a secret clearance. SAIC will sponsor the clearance process.
• Candidate must be a US Citizen.
• Experience in Digital Engineering, Modeling & Simulation (M&S), or systems integration, with emphasis on HWIL/SIL development and performance evaluation.
• Demonstrated experience in common engineering test beds that leverage HWIL/SIL for system and subsystem-level assessments.
• Proven track record in integrating M&S insights with Verification and Validation (V&V) or similar systems engineering disciplines.
• Hands-on knowledge of relevant tools such as MATLAB/Simulink, Python, STK, or other frameworks supporting M&S, HWIL, or SIL workflows.
• Strong proficiency in M&S methodologies, validation, and real-world scenario simulation.
• Excellent analytical skills for evaluating system behaviors, hardware-software integration, and model performance.
• Effective communication to articulate technical findings to diverse audiences, including engineering teams and non-technical stakeholders.
• Experience managing Digital Threads and contributing to model-centric workflows across the system lifecycle.

PREFERRED EXPERIENCE:

• Direct experience with missile systems, submarine-launched platforms, or similar defense applications.
• Familiarity with organizations like NSWC Crane Division, OSD, or Navy Strategic Systems Programs (SSP).
• Familiarity with guidance, navigation, and control (GNC) systems is a plus but not required.
• Certifications: INCOSE Certified Systems Engineering Professional (CSEP), or defense acquisition certifications in systems engineering.

Target salary range: $80,001 - $120,000. The estimate displayed represents the typical salary range for this position based on experience and other factors.
