How you will contribute:

We are seeking a Process Engineering Intern who combines analytical rigor with hands-on curiosity - someone who loves data as much as they love getting their boots dirty. Based on site at our Ranchito facility, you will own a defined process improvement project, focused on optimizing throughput or yield and supporting scale-up initiatives from R&D to commercial operations.

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.

This is a paid, part-time summer internship (hourly, non-exempt) lasting approximately 10–12 weeks, from late May/early June through August. Interns are expected to work approximately 20–25 hours per week, with some flexibility based on project needs and academic schedules. Compensation is $20/hour.

What you will be working on:

Process Optimization & Continuous Improvement:

• Analyze plant and process data to identify inefficiencies in yield, throughput, and resource utilization.
• Design, and support implementation, and validation of process improvements in collaboration with operations, maintenance, and controls teams.
• Develop models, SOPs, and documentation to institutionalize process knowledge.
• Contribute to and promote a data-driven, continuous improvement mindset across the plant.

Technology Transfer

• Support the translation of R&D findings into scalable manufacturing processes through documentation, analysis, and trial support
• Develop detailed process documentation including PFDs, P&IDs, and mass/energy balances.
• Collaborate with pilot and R&D teams to support design and execution scale-up trials.
• Support commissioning, validation, and troubleshooting of new process lines and equipment.

What your week will look like:

• Work at the commercial facility working on process improvements to drive yield, throughput, and resource utilization.
• 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.
• Transfer any new processes to the operations team through proper documentation and training.
• Update management team and other project engineers on project progress and requirements regularly in written reports and presentations.
• Track project milestones, document progress, and escalate risks or changes to the engineering lead as needed.

What you bring to Plantible:

• Planned B.S. or M.S. in Process, Chemical, Mechanical, or Bioprocess Engineering (or related discipline).
• Familiarity with PFD/P&IDs, H&M balances.
• 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.
