Design the Backbone of Clean Energy & Carbon Conversion Location: Franklin, TN (On-Site) Type: Full-Time Seniority: Mid to Senior Level / Technical Contributor
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 hiring a Process Engineer with a strong mechanical foundation to help design and deploy our next-generation waste-to-energy and carbon capture systems. This is not a modeling-only role. You'll work end-to-end—translating high-level process concepts to concrete designs by developing P&IDs, performing mass and energy balances, modeling processes, selecting hardware, guiding physical builds, and gaining insights from testing. By diving into technical challenges to turn concepts into reality, your work will sit at the core of how our systems perform in the real world. This role is perfect for process design engineers with a systems background and strong mechanical intuition who want to own full process-mechanical design and get hands-on in fabrication, instrumentation, and deployment.
What You’ll Do
Design & Simulate Separation Processes: Build and validate cyclic adsorption (TSA/PSA) flowsheets in process modeling software (including custom isotherm and kinetic models); analyze breakthrough curves, cycle efficiency, and heat integration
Perform Mass & Energy Balances: Develop detailed mass-energy balances for energy systems and carbon capture processes
Translate Models into Hardware: Generate PFDs and P&IDs from your process simulations; size pressure vessels, adsorption beds, heat exchangers, pumps/blowers, and piping networks based on process conditions
3D CAD Layout & Mechanical Detailing: Create or review CAD assemblies and AutoCAD schematics to ensure the process equipment fits skid dimensions and meets requirements
Support Fabrication, Commissioning, & Testing: Work with the shop and controls teams to oversee fabrication, instrumentation, and loop checks; participate in testing development and data review
Data Analysis & Model Refinement: Use testing results to update simulation parameters and re-optimize cycle timings or hardware specs
Cross-Functional Collaboration: Partner daily with chemical, mechanical, and controls engineers plus technicians, aligning on control strategies, safety interlocks, and operational procedures
Continuous Improvement: Identify design-to-cost opportunities and reliability enhancements; propose material, cycle, or control refinements to boost capture rate and reduce parasitic loads
Requirements
Education: B.S. or M.S. in Chemical Engineering or Mechanical Engineering with significant process modeling experience
Process Modeling: 3-8 years designing and simulating adsorption or gas-separation processes—expertise in Aspen Plus (including custom isotherms & dynamic cycles), gPROMS, or equivalent
Transport & Thermodynamics: Deep understanding of mass-transfer, reaction kinetics, heat-transfer, and property estimation methods
Experimental Validation: Proven ability to validate simulation and modeling results through lab-scale or pilot-scale experimentation—designing tests, analyzing data, and refining models accordingly
Mechanical Aptitude: Hands-on experience sizing pressure vessels, piping networks, heat exchangers, pumps, and blowers; experienced in SolidWorks/Inventor and AutoCAD
Field & Commissioning Experience: Familiarity with pilot-scale builds, instrumentation calibration, loop checks, and on-site troubleshooting
Bonus Points For
Hands-on experience with cyclic adsorption systems (TSA/PSA) using Aspen Adsorption or equivalent
Designing modular or containerized process skids for rapid deployment
Control-system co-simulation (DCS/PLC loop tuning, model-based control strategies)
CFD or multiphase-flow modeling to support detailed mechanical design
Scaling processes from pilot to demonstration or commercial units
Familiarity with gas-analysis instrumentation
Benefits & Why You’ll Love It Here
Mission with urgency: Your designs will help clean up emissions and generate real impact
Hands-on everything: If you’re not satisfied just modeling, you want to see your ideas come to life through building, testing, and owning full systems
Flat org, fast feedback: Make decisions, iterate quickly, and learn fast
Equity upside: Be part of a venture-backed team building breakthrough clean tech systems
Compensation & Benefits
Competitive salary + equity opportunity in a fast-growing climate tech company
401(k) plan and health insurance stipend (QSEHRA)
Paid vacation and holidays
