Enexor · Franklin, Tennessee, United States

 Pioneering Carbon Conversion and Renewable Energy Systems

Location: Franklin, TN (On-Site)
Type: Full-Time
Experience Level: Mid to Senior

Join Enexor BioEnergy

Located just outside Nashville, TN, Enexor is a fast-moving early-stage climate tech company building small-scale, waste-to-value systems that convert organic and plastic waste into renewable energy and high-purity CO₂. We’re not just innovating—we’re disrupting the status quo.

Why Join Us?

  • Mission-first impact: Help turn waste and emissions into energy and carbon-negative value streams.
  • Hands‑on innovation: Engineers here don’t just design—they build, test, iterate, and deploy real systems.
  • People over process: We move fast, cut red tape, and trust smart, driven individuals to take ownership.
  • High-value team: We hire the best; we challenge each other; we win together.

If you're ready to move beyond the drawing board and make real-world impact, come help shape the future of distributed energy and carbon conversion systems.

The Role

We’re hiring Senior Mechanical Engineers and a Mechanical Engineering Manager to support the design, development, and deployment of our next-generation waste-to-energy system and our post-combustion carbon capture system. These roles will focus on subsystem design, cross-functional integration, and end-to-end ownership of mechanical program execution.

These positions are ideal for senior-level engineers and technical leaders who thrive in a fast-paced, hardware-driven environment. You'll be involved from initial concept and design through fabrication, testing, and deployment.

Key Responsibilities

  • Design, model, and test mechanical subsystems for gas separation, thermal systems, and pressure environments.
  • Integrate capture modules with upstream flue gas sources and downstream conditioning units.
  • Own full mechanical lifecycle from concept through CAD, DFM, BOM, sourcing, and assembly.
  • Use tools like INVENTOR, ANSYS, ASPEN, and MATLAB to optimize design performance.
  • Lead testing and validation: build rigs, instrument systems, collect data, and iterate fast.
  • Collaborate with process, controls, and fabrication teams to ensure seamless system integration.
  • Support design-to-cost strategy and scaling for manufacturability.

Requirements

Required Qualifications

  • B.S. or M.S. in Mechanical Engineering or related discipline.
  • 3–10 years of mechanical design and systems integration experience.
  • Strong proficiency in 3D CAD (Autodesk Inventor preferred) with working knowledge of FEA and CFD.
  • Demonstrated ability to take systems from concept to prototype to deployment.
  • Hands-on experience with piping, pressure systems, structural frames, or heat exchangers.
  • Solid analytical and first-principles problem-solving skills.

Preferred Experience

  • Experience working with swing adsorption systems (e.g., PSA, VSA, or similar gas separation technologies).
  • Background in flue gas treatment, gas purification, or emissions control systems.
  • Familiarity with containerized or modular systems for field deployment.
  • Experience in techno-economic analysis or cost-driven design.
  • Certifications such as P.E., PMP, or MBA are beneficial but not required.

Benefits

Compensation & Benefits

  • Equity opportunity in a fast-scaling, venture-backed climate tech company.
  • Competitive salary based on experience and impact.
  • Health insurance stipend (QSEHRA) and 401(k) plan.
  • Paid vacation and holidays.

To Apply:
Send your resume and a brief note to careers@enexor.com. Highlight your experience with swing adsorption or mechanical system development in clean energy or gas separation.
