Process Engineer

Clean Crop Technologies builds domestic supply chains for specialty crops. We work with growers from seed through processing to deliver food-grade products to buyers who have historically relied on imports. Our first crop, mung beans, is in commercial production, and we are expanding into additional pulses and grains.

Our commercial processing operation runs at a partner mill campus in Hennessey, Oklahoma, where we receive, clean, sort, grade and store products alongside our operating partner. Our R&D and pilot operations are in Holyoke, Massachusetts. We are a venture-backed company.

We are looking for a Process Engineer to own the technical performance of our mung bean processing line in Hennessey. You will set and calibrate the cleaning, optical sorting and gravity equipment to each customer specification, trace yield loss and grading defects back to their cause, and run the trials that correct them. You will keep the equipment reliable through preventive maintenance and small capital projects, and design how each new pulse and grain will run on the line as we expand. You will work on site alongside our Production Manager, our QA Manager and customer partners. You will also work closely with our Product team in Massachusetts.

Process Ownership

• Own the facility layout and equipment performance
• Set, document and maintain equipment settings for each crop and customer specification, and adjust them as incoming lots vary
• Track yield, throughput, OEE and downtime, find the causes of loss, and run the trials that improve them
• Troubleshoot off-spec product with the QA Manager, trace the cause back through the process, and put the fix in place
• Write and keep current the SOPs, work instructions and process documentation the floor team runs from

• You have 4+ years as a process, manufacturing or plant engineer in food, grain, seed, feed or another bulk solids operation
• You have hands-on experience with cleaning, sorting, milling or material handling equipment, and are comfortable working on the floor
• You use data to improve a process: you have tracked yield, throughput or OEE and can point to a change you made that moved it
• You can read mechanical and electrical drawings and troubleshoot equipment and basic controls
• You write clear SOPs and can train a floor team to follow them
• You have a degree in chemical, agricultural, biological, food or mechanical engineering, or equivalent experience through a technical program and time on the plant floor
• You do well on a small team where you will often be the person who figures it out, and you know when to call a vendor or a peer who has solved it before
• You are willing to relocate to, or already live within commuting distance of, Hennessey, Oklahoma

• Experience processing pulses, specialty grains or seed (mung beans, lentils, chickpeas, quinoa or similar)
• Optical sorter setup and calibration (Bühler, Satake, TOMRA, Key Technology or similar)
• SQF, BRCGS or other GFSI food safety program experience
• Commissioning a new line or facility
• PLC or HMI experience

• You will own the process at our main commercial site, with direct influence on how it runs and where we invest
• You will bring new crops onto the line as the company grows, so the role keeps expanding
• You will work with a small, hands-on team that values solving the customer's problem over using a particular technology
• You will have ownership, autonomy and equity participation in an early-stage company
