This position is vacant.
Canadian Biojet Fuel Laboratories (CBFL), a division of Greenfield Global is looking for a  Junior Process Engineer  to join our growing team.

Position Overview  The Junior Process Engineer will support Canadian Biojet Fuel Laboratories’ (CBFL) Sustainable Aviation Fuel (SAF) pilot operations and process development program in Sarnia, Ontario. This full-time, permanent role combines process engineering, pilot plant operations, and the need to secure the necessary experimental development learnings in an efficient and safe manner to advance CBFL’s Mixed-Alcohol-To-Jet (MATJ) and Fischer–Tropsch (FT) pathways toward ASTM-compatible fully synthetic aviation fuel.

The engineer will lead teams of pilot plant operators to execute test campaigns, maintain process models and engineering documentation ensuring that operating data (including analytical) is accurate in order to drive all the necessary development learnings to support scale-up from pilot to demonstration and then to commercial facilities. Occasional travel to partner facilities (e.g., University of Alberta) may be required for commissioning support and technical alignment.
This role is primarily on-site at CBFL’s Sarnia Research Park pilot facility. The pilot plant operates on a continuous basis, and the successful candidate will participate in an on-call rotation, weekend work and occasional off-shift support as required. Occasional travel to partner facilities may be required.

From start-ups to the largest brands in the world, customers trust Greenfield’s extensive portfolio of premium products, regulatory expertise, and industry-leading service to improve people’s lives and the health of the planet.
Why Join Greenfield?  We innovate, collaborate, and work with purpose. By unlocking the potential of people, partnerships, and nature to accelerate sustainable solutions for the health of the planet, our work has a positive impact on the environment around the world. We’re always looking for people who can bring new talents and experience to our team.
Who You Are   Bachelor’s degree in Chemical Engineering working towards Professional Engineer designation.
Proficiency with process simulation tools (Aspen Plus/HYSYS or equivalent) and strong competency in mass/energy balances.
Demonstrated ability to analyze process data (e.g., Python, Excel, PI historian tools) and translate results into operational improvements.
Excellent communication skills, including the ability to write clear technical reports and work effectively with multidisciplinary teams.
Your Experience Should Include   2+ years of process engineering and/or pilot plant operations experience in fuels, petrochemicals, refining, catalysis, or related process industries.

Experience with catalytic hydrocarbon processing, reactor operations, and process troubleshooting especially in the field of sustainable aviation fuel (SAF) is highly preferred.

Experience with the four tier levels in the ASTM SAF development/ testing / approval system is an asset.
Strong safety mindset and experience working within Process Safety Management frameworks (HAZOP/MOC).

Job Responsibilities   Comply with all company health and safety, and environmental policies and regulatory requirements.
Provide process engineering leadership for pilot plant operations, optimization, and continuous improvement of CBFL’s MATJ multi‑stage pilot systems (and related SAF development assets).
Responsible for developing experimental campaigns, arranging for resources, monitoring the trials as they are ongoing, and documenting the results of the campaign including catalyst performance, conversion efficiency, product distribution, and fuel property outcomes.
