Senior / Principal Structural Engineer

Lead and advance Cardinal Engineering’s structural analysis and computational mechanics initiatives across a portfolio of high-priority Department of Defense and maritime programs. In this role, you will serve as a senior technical authority on the assessment, survivability, and life-cycle support of Navy surface ship structures, submarine systems, and underwater vehicles. Working within a multidisciplinary team, you will translate complex mission requirements into high-fidelity structural models, guide trade studies, and ensure structural performance and shock survivability in extreme marine environments.

Position Expectations

• Technical Leadership & Analysis: Lead and execute high-fidelity Finite Element Analysis (FEA) for complex static, dynamic, transient, and non-linear loading conditions using FEMAP/NASTRAN.
• Workflow Innovation: Drive team efficiency by architecting and implementing custom automation tools, macros, and API scripts (FEMAP API) to streamline standard modeling, analysis, and post-processing workflows.
• Technical Products & Substantiation: Oversee the generation and technical review of comprehensive analysis packages, substantiation reports, and structural drawing sets for critical fleet assets.
• Survivability & Optimization: Direct structural trade studies to optimize weight, cost, and manufacturability while strictly adhering to naval survivability and strength standards.
• Client & Stakeholder Interface: Serve as a primary technical point of contact for Navy technical authorities, NAVSEA program offices, and prime contractors, regularly presenting findings and defending analytical approaches during major design reviews.
• Standards & Mentorship: Enforce internal analysis standards, verification methodologies, and best practices for the Structural Engineering Group while mentoring mid-level and junior staff.
• Work Location: Based out of our Washington, D.C., Pawcatuck, CT, or Linwood, PA, offices in a hybrid environment, with in-office presence driven by project requirements and secure facility needs.
• Travel: Occasional travel (less than 20%) to shipyards, partner facilities, and government test sites.

Required Qualifications

• Education: Bachelor’s degree in Mechanical, Aerospace, Civil, Naval Architecture, or Ocean Engineering.
• Experience: 8 years of progressive experience in advanced structural analysis and computational mechanics, with a strong emphasis on defense or maritime applications.
• Technical Expertise: Demonstrated experience acting as a technical lead or subject matter expert on complex FEA projects using FEMAP and NASTRAN.
• Communication: Strong briefing and communication skills, with proven success presenting technical risk, analytical methodology, and design trade-offs to senior leadership and government customers.
• Security Clearance: Must be a US Citizen and possess an active Secret security clearance, or have the ability to obtain and maintain a DoD Secret clearance.

Desired Qualifications

• Advanced Education: Advanced degree (MS or PhD) specializing in Solid Mechanics, Computational Mechanics, or Structural Dynamics.
• Automation Skills: Advanced proficiency in FEMAP API development using Python, C , or VBA to build automated analysis toolkits.
• Naval Domain Knowledge: In-depth mastery of Navy ship design practices, including hull structures, equipment foundations, and shock/vibration qualification.
• Naval Standards: Direct experience with naval structural standards and criteria (e.g., DDS-100 series, MIL-STD-167, MIL-DTL-901).
• Specialized Analysis Skills: Expertise in Dynamic Design Analysis Method (DDAM) and Underwater Explosion (UNDEX) response modeling is highly desirable.

Compensation and Benefits

• Salary: $130,000 – $185,000 per year (commensurate with experience and level of technical expertise).
• Employee Benefits: Cardinal Engineering is an equal opportunity employer and offers an industry-leading compensation and benefits package, including:

· Generous 401(k) company contribution with immediate vesting

· Comprehensive medical, dental, and vision coverage

· Flexible Spending Account (FSA) and Dependent Care Account

· Short-term and long-term disability protection

· Company-paid life and AD&D insurance plans
