Join Enexor Bio Energy

Located just outside Nashville, TN, Enexor is a fast‑moving early‑stage climate tech company building small‑scale, waste‑to‑value systems that convert organic and plastic waste into renewable energy and high‑purity CO₂.

• Mission‑first impact:
  Turn waste and emissions into energy and carbon‑negative value streams.
• Hands‑on innovation:
  Engineers here design, build, test, iterate, and deploy real systems.
• People over process:
  Fast pace, minimal red tape, and high trust.
• High‑value team:
  We hire the best, challenge each other, and win together.

We’re hiring Senior Mechanical Engineers and a Mechanical Engineering Manager to support the design, development, and deployment of our next‑generation waste‑to‑energy system and post‑combustion carbon capture system. These roles focus on subsystem design, cross‑functional integration, and end‑to‑end mechanical program ownership.

Ideal candidates thrive in a fast‑paced, hardware‑driven environment and participate from initial concept through fabrication, testing, and deployment.

• 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 the full mechanical life cycle 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 quickly.
• Collaborate with process, controls, and fabrication teams to ensure seamless system integration.
• Support design‑to‑cost strategy and scaling for manufacturability.

• 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.

• Experience 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.

• 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.
