Senior Mechanical Engineer

About the role

Join Enexor BioEnergy, a pioneering climate tech company located just outside Nashville, TN, focused on converting waste and plastic into renewable energy and high-purity CO₂.

Responsibilities

• Design, model, and test mechanical subsystems for gas separation, thermal systems, and pressure environments
• Integrate capture modules with upstream flue gas sources and downstream conditioning units
• Own full mechanical lifecycle from concept through CAD, DFM, BOM, sourcing, and assembly
• Use tools like INVENTOR, ANSYS, ASPEN, and MATLAB to optimize design performance
• Lead testing and validation: build rigs, instrument systems, collect data, and iterate fast
• Collaborate with process, controls, and fabrication teams to ensure seamless system integration
• Support design-to-cost strategy and scaling for manufacturability

Requirements

• B.S. or M.S. in Mechanical Engineering or related discipline
• 3-10 years of mechanical design and systems integration experience
• Strong proficiency in 3D CAD (Autodesk Inventor preferred) with working knowledge of FEA and CFD
• Demonstrated ability to take systems from concept to prototype to deployment
• Hands-on experience with piping, pressure systems, structural frames, or heat exchangers
• Solid analytical and first-principles problem-solving skills

Preferred Experience

• Experience working with swing adsorption systems (e.g., PSA, VSA, or similar gas separation technologies)
• Background in flue gas treatment, gas purification, or emissions control systems
• Familiarity with containerized or modular systems for field deployment
• Experience in techno-economic analysis or cost-driven design
• Certifications such as P.E., PMP, or MBA are beneficial but not required

Benefits

• Equity opportunity in a fast-scaling, venture-backed climate tech company
• Competitive salary based on experience and impact
• Health insurance stipend (QSEHRA) and 401(k) plan
• Paid vacation and holidays
