Director of Engineering

Build the Future of Carbon Conversion & Renewable Energy

Location: Franklin, TN (On-Site)

Type: Full-Time

Seniority: Director / Leadership

Join Enexor BioEnergy

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 CO. We are reimagining how the world addresses emissions, waste, and energy access-one modular system at a time.

We're not just solving problems. We're redefining what's possible at the intersection of engineering, energy, and sustainability.

Why This Role Matters

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.

This is a critical leadership role reporting directly to the CEO. You will own the engineering organization while collaborating across product development, fabrication, and field deployment to take ideas from whiteboard to world-changing systems.

What You'll Do

• 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.
• Partner with the CEO and executive team on strategic initiatives, resource planning, and technical hiring.
• Instill a culture of ownership, urgency, and innovation in everything you build.
