Senior Chemical Engineer 1 (8603A)

Are you an experienced chemical or process engineer ready to help bring renewable fuels technology to commercial scale? Join Applied Research Associates’ Better Fuels Group (BFG) — an industry leader in advanced biofuels and sustainable energy — and be part of the team driving the next generation of clean fuel innovation.

We’re looking for a hands-on, creative engineer with strong process design experience to help bridge the gap between pilot testing and full commercial implementation. If you’ve got refinery, renewable diesel, or petrochemical experience — and love solving tough engineering challenges — this is your opportunity to make a global impact.

What You’ll Do

As a Senior Process Engineer, you’ll take ownership of key process engineering and project execution activities that bring cutting-edge renewable fuels technologies to life. You will:

• Develop and deliver engineering data packages (PFDs, P&IDs, H&MBs, equipment specs).


• Review and guide EPC contractor design deliverables to ensure alignment with technology requirements.


• Design and specify major process equipment for renewable fuel and petrochemical systems.


• Support scale-up and commercial implementation of novel renewable processes.


• Create standard operating procedures, startup manuals, and training materials.


• Participate in HAZOP reviews, commissioning, and post-startup optimization.

What We’re Looking For

• B.S. or higher in Chemical Engineering.


• 5–10+ years of experience in refinery, petrochemical, or renewable fuels design or EPC.


• Strong understanding of process design fundamentals, simulation, and heat/material balances.


• Proficiency with DCS/SIS systems and process control integration.


• Experience with HAZOPs, process safety, and startup/commissioning.


• Creative problem solver with a practical mindset and strong communication skills.


• Willingness to travel up to 10% (domestic/international).

Why Join ARA’s Better Fuels Group

• Work on commercial renewable fuel projects that are already being built and operated around the world.


• Collaborate with scientists, engineers, and business leaders developing proven, patented clean-energy technologies.


• Enjoy a culture of innovation, integrity, and balance — where your ideas and initiative are valued.


• Competitive pay, excellent benefits, and opportunities for growth within a respected, employee-owned company.
