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 CO2. 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.

Requirements

What We're Looking For

• B.S. or M.S. in Mechanical Engineering or related field; deep hardware/system experience required.
• 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.
• Comfortable wearing multiple hats: player-coach, mentor, problem-solver, and executor.
• Bonus: Familiarity with modular product design, automation, or containerized systems.

Benefits

Why You'll Love It Here

• Mission with urgency: You'll help solve real-world energy and emissions problems with technology that scales.
• No red tape: Fast decisions, flat org, and deep ownership.
• Equity upside: This is an early-stage leadership opportunity with real skin in the game.
• True engineering culture: We build, we test, we fix, we deploy.

Compensation & Benefits

• Competitive salary + equity stake in a fast-growing climate tech company.
• 401(k) plan and health insurance stipend (QSEHRA).
• Paid vacation and holidays.
