Core Responsibilities

Primary Functions

  • Design, model (using CAD), and implement scalable hydroponic and aeroponic systems, including NFT, DWC, and vertical drip irrigation configurations, from concept to commissioning.
  • Develop and maintain comprehensive Process and Instrumentation Diagrams (P&IDs) for all water, nutrient, and air handling systems within the facility.
  • Manage the complete lifecycle of farm automation systems, including PLC programming, HMI development, and troubleshooting of automated fertigation and climate control logic.
  • Spearhead the integration, calibration, and maintenance of a wide array of environmental sensors, including those for pH, EC, dissolved oxygen, temperature, humidity, CO2, and PAR.
  • Conduct root-cause analysis and perform complex troubleshooting on mechanical, electrical, and plumbing (MEP) systems, including pumps, chillers, filters, valves, and dosing equipment.
  • Develop and execute preventative maintenance schedules for all critical farm infrastructure to minimize downtime and ensure operational reliability.
  • Engineer and optimize HVAC and dehumidification systems to maintain precise temperature, humidity, and airflow setpoints tailored to specific crop requirements.
  • Formulate, monitor, and precisely adjust multi-part nutrient solution recipes based on crop growth stages, water quality analysis, and real-time sensor feedback.
  • Lead research and development (R&D) projects to trial new equipment, technologies, and growing methodologies aimed at improving yield, resource efficiency, and crop quality.
  • Analyze large datasets collected from farm management software and sensor networks to identify trends, predict issues, and drive data-informed operational improvements.
  • Create and enforce Standard Operating Procedures (SOPs) for all engineering and maintenance tasks to ensure safety, consistency, and compliance with food safety standards (e.g., GAP, GMP).
  • Manage vendor relationships and procure necessary components, equipment, and consumables, ensuring quality and cost-effectiveness.
  • Collaborate closely with the Head Grower and plant science team to align engineering initiatives with agronomic goals and resolve plant health issues related to system performance.
  • Oversee the installation and commissioning of new farm builds or expansion projects, managing timelines, budgets, and contractors.
  • Develop and implement robust water treatment and recycling protocols to maximize water use efficiency and maintain system hygiene.
  • Design and manage integrated lighting systems, including spectrum, intensity (DLI), and photoperiod optimization for various crops.
  • Ensure all systems and operational procedures comply with local, state, and federal environmental and worker safety regulations (e.g., OSHA).
  • Train and mentor junior engineers and farm technicians on system operations, safety protocols, and maintenance procedures.
  • Prepare detailed technical reports, performance dashboards, and presentations for senior management on system efficiency, project status, and key operational metrics.
  • Drive continuous improvement initiatives (e.g., Lean, Six Sigma) within the farm's technical operations to enhance productivity and reduce operational costs.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis to uncover new operational insights.
  • Contribute to the organization's long-term technology and data strategy roadmap.
  • Collaborate with business units to translate future crop and production needs into tangible engineering requirements.
  • Participate in sprint planning and agile ceremonies within the data and technology teams.
