What are the responsibilities and job description for the Director of Engineering position at Enexor?
Location: Franklin, TN (On-Site)
Type: Full-Time
Seniority: Director / Leadership
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 MattersWe’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.
- 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.
- 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.
