Process Engineer

Process Engineer

Plantible, backed by Astanor Ventures, Lerer Hippeau, Piva Capital, Kellogg's, and Vectr Ventures, is a vertically integrated biology company that is unlocking the power in plants in service of people & planet. Our mission is to create solutions that empower customers to make sustainable and regenerative choices without compromising on quality. We are beginning with the food industry.

We are seeking a process engineer who combines analytical rigor with hands-on curiosity - someone who loves data as much as they love getting their boots dirty. Based in Austin but frequently on site at our Ranchito facility, you will lead projects that optimize throughput, drive yield improvements, and scale technologies from R&D into full commercial operation.

This role is ideal for someone who thrives in a fast-paced, high-impact startup environment—working shoulder to shoulder with operators, scientists, and engineers to continuously improve our production process from cultivation to packaging.

Process Optimization & Continuous Improvement

• Analyze plant and process data to identify inefficiencies in yield, throughput, and resource utilization.
• Design, implement, and validate process improvements in collaboration with operations, maintenance, and controls teams.
• Develop models, SOPs, and documentation to institutionalize process knowledge.
• Champion a data-driven, Kaizen mindset across the plant.

Technology Transfer

• Translate R&D findings into robust, scalable manufacturing processes.
• Develop detailed process documentation including PFDs, P&IDs, and mass/energy balances.
• Collaborate closely with pilot and R&D teams to design and execute scale-up trials.
• Support commissioning, validation, and troubleshooting of new process lines and equipment.

Capital & Engineering Projects

• Scope and execute CAPEX projects that enhance safety, reliability, and performance.
• Support the design and implementation of automation and control improvements.

What Your Week Will Look Like

• Work closely with the Engineering, Operations and Research teams to optimize current processes and scale up new developments.
• Spend time at the commercial facility working on process improvements & new engineering developments to successful tech transfers.
• Develop and communicate process designs using process flow diagrams, P&IDs, process narratives, and volume and mass balances.
• Monitor operations and project progression, resolve any issues that arise, and coordinate team activities to maintain the approved schedule.
• Update management team and other project engineers on project progress and requirements regularly in written reports and presentations.
• Control project pace and budget and manage project changes as needed.

What You Bring To Plantible

• B.S. or M.S. in Process, Chemical, Mechanical, or Bioprocess Engineering (or related discipline).
• 3–7 years of hands-on experience in food, biotech, or ingredient manufacturing; preferably in protein or fermentation systems.
• Proven ability to lead process optimization and scale-up initiatives.
• Familiarity with PFD/P&ID drafting, H&M balances, and process simulation tools (e.g., Aspen, SuperPro, AutoCAD, or equivalent).
• Understanding of sanitary design, food safety (HACCP, FSMA), and equipment standards (USDA, FDA).
• Strong communication skills; comfortable bridging R&D and plant operations.
• A proactive, "get-it-done" attitude with the flexibility to work on-site at Ranchito as projects demand.
