General Engineering/HVAC

Build the Future of Carbon Conversion & Renewable Energy

Franklin, TN (On-Site)

Type: Full-Time

Enexor is a venture-backed, early-stage climate tech company just outside of Nashville, TN, developing distributed systems that turn organic and plastic waste into clean energy and high-purity CO₂. We are reimagining how the world addresses emissions, waste, and energy access—one modular system at a time.

We’re redefining what’s possible at the intersection of engineering, energy, and sustainability.

We’re seeking a Director of Engineering to lead and scale our multidisciplinary engineering team as we develop, build, and deploy the next generation of our waste-to-energy and carbon capture systems. You’ll be both strategist and builder—setting the engineering vision, managing execution, and rolling up your sleeves to help solve complex hardware challenges.

You will own the engineering organization while collaborating across product development, fabrication, and field deployment to take ideas from whiteboard to world-changing systems.

Lead and grow a world-class mechanical, electrical, and controls engineering team.

Drive end-to-end product development—from concept to CAD, DFM, fabrication, commissioning, and continuous improvement.

Build scalable engineering processes that support rapid prototyping and high-reliability deployment.

Own technical architecture decisions and cross-functional integration across subsystems (combustion, thermal, gas separation, pressure, controls).

Guide engineering trade-offs with strong first-principles thinking and cost-performance analysis.

S. in Mechanical Engineering or related field; 10+ years of engineering experience, including 5+ in technical leadership or management roles.

Proven success developing complex mechanical or thermal systems—ideally in energy, emissions, or industrial environments.

Hands-on experience with pressure vessels, piping, structural systems, heat transfer, or adsorption tech is a major plus.

Strong grasp of CAD (Inventor), simulation (FEA/CFD and other Process Modeling), and manufacturing workflows.

Bonus: Familiarity with modular product design, automation, or containerized systems.

You’ll help solve real-world energy and emissions problems with technology that scales.

Equity upside: This is an early-stage leadership opportunity with real skin in the game.

True engineering culture: Competitive salary + equity stake in a fast-growing climate tech company.

401(k) plan and health insurance stipend (QSEHRA).

Paid vacation and holidays.
