Senior/Principal Structural Analyst

Zeno is seeking a highly motivated Senior/Principal Structural Analyst to support the mission-oriented efforts of developing and bringing to market Radioisotope Power Systems (RPS) technologies. This role will be reporting to the Analysis Manager.

In this role you will:

• Perform detailed mechanical and structural analyses of Radioisotope Power System (RPS) structures, subsystems, and components across all program phases-from early concept and prototype to qualification and flight hardware.
• Evaluate mechanical performance against structural limits, regulatory requirements, and applicable design and pressure vessel codes (ASME BPVC, AWS D1.1, etc.).
• Apply NASA structural design and verification standards (e.g., NASA-STD-5001, NASA-STD-5012, NASA-HDBK-7004, NASA-STD-7009) to ensure compliance with flight-class structural integrity, safety factors, and analysis documentation practices.
• Assess component margins and performance under mechanical, thermal, and acoustic environments using static, model, vibration, and explicit dynamic analyses.
• Document findings and provide guidance through clear, traceable analysis reports that conform with Zeno Power technical writing standards.
• Develop test requirements and plans to validate analytical results; correlate test data to analytical models and update predictions as required.
• Provide oversight and mentorship to internal analysts, review vendor and partner analysis deliverables for technical accuracy, compliance, and quality consistency.
• Provide input and guidance to mechanical design teams to inform component sizing, subsystem configuration, and material selection.
• Collaborate closely with systems, materials, and test engineers to ensure robust, manufacturable, and testable hardware designs.

Key Qualifications and Skills

• B.S. or higher in Mechanical or Aerospace Engineering from an accredited university (M.S. preferred).
• 7+ years of experience in structural analysis including steady state, random vibration, and thermal environments for aerospace or nuclear systems.
• Demonstrated proficiency and deep understanding of FEA tools (ANSYS Mechanical preferred; Abaqus, Nastran, or LS-DYNA a plus).
• Strong background in dynamic structural analysis, including random vibration, sine sweep, shock, and transient response.
• Experience with impact, re-entry, or launch environment analyses is a plus.
• Working knowledge of NASA standards and verification processes (NASA-STD-5001B, NASA-STD-5012, NASA-HDBK-7005, NASA-STD-7009) highly desired.
• Familiarity with fracture mechanics, fatigue life estimation, and damage tolerance principles.
• Experience generating stress reports and component margins justifications consistent with NASA or aerospace prime contractor standards.
• Working knowledge of 3D CAD tools (SolidWorks or similar) and GD&T (ASME Y14.5) for model-based definition and analysis.
• Experience working under structured quality systems (NQA-1, AS9100, ISO 9001, or similar).
• Excellent technical writing skills and ability to present results clearly to technical and non-technical audiences.
• Self-starter capable of leading analysis efforts with minimal supervision, thriving in a fast-paced, multidisciplinary environment.
• Strong collaboration and communication skills; able to work independently or as part of a cross-functional team.
