Core Responsibilities

Primary Functions

  • Nutrient Solution Management: Precisely formulate, mix, and manage hydroponic nutrient solutions, regularly monitoring and adjusting pH, Electrical Conductivity (EC), and temperature to meet the specific needs of various crops at different growth stages.
  • Seeding and Propagation: Execute seeding and cloning protocols with precision, ensuring high germination and survival rates, and nurturing seedlings and young plants in dedicated propagation areas before transplanting.
  • Transplanting and Crop Spacing: Carefully transplant seedlings into the main hydroponic grow systems (e.g., NFT, DWC, Ebb and Flow), ensuring proper spacing and handling to minimize transplant shock and optimize plant density.
  • Daily Crop Health Monitoring: Conduct meticulous daily inspections of all crops to scout for early signs of pests, diseases, nutrient deficiencies, or other physiological stressors, documenting observations in detail.
  • Integrated Pest Management (IPM) Implementation: Proactively implement IPM strategies, including the release of beneficial insects, application of approved biological or chemical controls, and maintenance of a clean growing environment to prevent pest outbreaks.
  • Environmental Control System Operation: Monitor and operate advanced environmental control systems to manage temperature, humidity, CO2 levels, and lighting schedules (photoperiod and intensity), ensuring the climate is optimized for crop growth.
  • Harvesting and Post-Harvest Handling: Lead and participate in harvesting activities, adhering to strict schedules and quality standards, and oversee initial post-harvest tasks such as trimming, weighing, and preparing produce for packing.
  • System Maintenance and Sanitation: Perform routine cleaning, sanitation, and preventative maintenance on all hydroponic equipment, including pumps, filters, dosers, irrigation lines, and grow trays, to ensure operational efficiency and food safety.
  • Data Collection and Record-Keeping: Diligently collect and log critical data related to crop growth, environmental parameters, nutrient usage, pest observations, and harvest yields, using farm management software or spreadsheets.
  • Adherence to SOPs and Food Safety: Strictly follow all Standard Operating Procedures (SOPs) and Good Agricultural Practices (GAPs) to ensure consistency, quality, and compliance with food safety regulations.
  • Troubleshooting and Problem Solving: Act as the first line of defense in identifying and troubleshooting issues with plant health, environmental controls, or hydroponic system mechanics, implementing corrective actions swiftly.
  • Crop Scheduling and Planning: Assist in the planning and execution of the crop production schedule, ensuring a continuous and predictable supply of produce to meet demand.
  • Pruning and Plant Maintenance: Perform crop-specific maintenance tasks such as pruning, de-leafing, and trellising to improve airflow, light penetration, and overall plant health and productivity.
  • Equipment Calibration: Regularly calibrate sensors, meters, and monitoring equipment (e.g., pH meters, EC sensors, environmental probes) to ensure accurate data collection and system control.

Secondary Functions

  • Inventory Management: Assist in tracking and managing inventory of essential growing supplies, including seeds, growing media, nutrients, and IPM consumables, and communicate replenishment needs.
  • Research and Development Support: Contribute to ongoing R&D trials by executing experimental protocols, collecting data on new cultivars or growing techniques, and providing observational feedback.
  • Training and Mentorship: Assist in training new technicians and junior growers on standard operating procedures, safety protocols, and daily cultivation tasks.
  • Process Improvement Contribution: Proactively identify opportunities for improving efficiency, yield, and quality within the cultivation process and communicate suggestions to the Head Grower or management.
  • Support ad-hoc data requests and exploratory data analysis: Pull specific crop-cycle data or environmental logs to help the management team analyze trends or investigate anomalies.
  • Contribute to the organization's data strategy and roadmap: Provide on-the-ground feedback on the usability and effectiveness of farm management software and data collection tools.
  • Collaborate with business units to translate data needs into engineering requirements: Work with maintenance or engineering teams to explain cultivation-related needs for system upgrades or repairs.
  • Participate in sprint planning and agile ceremonies within the data engineering team: Engage in team meetings to review weekly goals, report on progress, and plan upcoming cultivation tasks and projects.

Required Skills & Competencies

Hard Skills (Technical)

  • Plant Science Knowledge: Strong understanding of plant physiology, nutrition, and pathology, particularly in the context of common leafy greens, herbs, and fruiting crops.
  • Hydroponic System Expertise: Hands-on experience with various hydroponic systems (e.g., Nutrient Film Technique, Deep Water Culture, Aeroponics) and their operational requirements.
  • Environmental Control: Proficiency in operating and interpreting data from environmental control software and hardware (HVAC, lighting, CO2 injection).
  • Water Quality and Nutrient Management: The ability to accurately test water quality, calculate nutrient recipes, and manage pH and EC levels for optimal plant uptake.
  • Integrated Pest Management (IPM): Knowledge of common pests and diseases in CEA and experience with scouting, identification, and a variety of control methods.
  • Data Logging and Analysis: Competence in using spreadsheets (Excel, Google Sheets) or farm management software to record, track, and interpret cultivation data.
  • Mechanical Aptitude: Basic troubleshooting skills for mechanical and plumbing components of hydroponic systems, such as pumps, filters, and irrigation lines.
