Process Engineer

About the role

Join Enexor BioEnergy, a venture-backed, early-stage climate tech company in Franklin, TN, developing distributed systems that convert organic and plastic waste into clean energy and high-purity CO₂. As a Process Engineer, you will design and deploy next-generation waste-to-energy and carbon capture systems, working end-to-end from concept to implementation.

Responsibilities

• 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.
• Scales processes from pilot to demonstration or commercial units.
• Familiarity with gas-analysis instrumentation.

Benefits

Competitive salary + equity opportunity in a fast-growing climate tech company. Includes a 401(k) plan and health insurance stipend (QSEHRA), paid vacation and holidays.
