• Optimize materials selection, wall thickness, and stress distribution for high-pressure applications.
• Review and approve detailed CAD models, engineering drawings, and manufacturing plans .
• Oversee welding, non-destructive testing (NDT), and quality assurance processes .
• Provide technical expertise in fabrication, machining, and testing methods for pressure vessels .

• Drive compliance with DOT, MIL-STD, and other relevant pressure vessel regulations .
• Monitor fabrication processes, welding techniques, and inspection methods to ensure structural integrity.
• Support pressure testing, validation, and regulatory certification of compressed gas cylinders.
• Work closely with Quality and Manufacturing teams to ensure repeatable, high-precision production .
• Develop and implement best practices for pressure vessel manufacturing and assembly .

• Serve as a technical authority for internal teams and external customers.
• Interface with customers to translate mission requirements into practical, manufacturable solutions .
• Provide technical expertise in program meetings, proposal development, and customer reviews .
• Collaborate with the BD team to assess feasibility and ensure realistic project execution .
• Represent Applied Companies in industry conferences, technical forums, and regulatory discussions .

You are a highly experienced, results-driven engineer with a deep understanding of pressure vessel design, fabrication, and compliance . You thrive in high-stakes, fast-paced environments where attention to detail and technical rigor are paramount. You take pride in delivering life-saving, military/aerospace-grade products that perform under the most demanding conditions.

• 10+ years of experience in pressure vessel design, manufacturing, and regulatory compliance .
• Expert-level knowledge of DOT, MIL-SPEC, and pressure vessel industry standards (ASME BPVC knowledge is a plus but not required).
• Hands-on experience with welding, heat treatment, NDT, and quality assurance processes .
• Strong proficiency in CAD (SolidWorks, AutoCAD) and FEA tools (ANSYS, ABAQUS, NASTRAN, or similar) .
• Ability to analyze and optimize high-pressure gas storage systems , including Type I and Type III pressure vessels .
• Experience supporting customer programs, technical reviews, and cross-functional collaboration .
• Proven track record of leading complex engineering projects from concept through manufacturing.
• Ability to obtain and maintain security clearance (preferred).

• Experience with high-performance materials, composites, and advanced manufacturing techniques .
• Background in HVAC systems, thermal management, or aerospace pressure vessel applications .
• Familiarity with Lean Six Sigma, Design for Manufacturability (DFM), and Continuous Improvement .
• Analytical/scientific programming skills (Python, MATLAB, Excel VBA, etc.).

• Impact: Your work directly supports warfighters, aerospace programs, and mission-critical applications .
• Innovation: Work on cutting-edge technologies in pressure vessel and thermal management engineering .
• Career Growth: Lead high-impact projects with opportunities for technical and leadership advancement .
• Collaborative Culture: Join a team of highly skilled engineers, problem-solvers, and industry experts .
• Comprehensive Benefits: Competitive salary, medical, dental, vision, 401K match, and profit-sharing .
