Director of Engineering

Overview

Build the Future of Carbon Conversion & Renewable Energy

Location:

Franklin, TN (On-Site). Type:
Full-Time. Seniority:
Director / Leadership.

Join Enexor Bio Energy. 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.

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.

• 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

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

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

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