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. 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. 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. Ready to Lead?
