Process Engineer

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 What We're Looking For - 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. Ready to Design Systems That Matter? Send your resume and a brief note to careers@enexor.com.
