Core Responsibilities

Primary Functions

Design, implement, and meticulously manage advanced irrigation and fertigation systems to ensure precise delivery of water and nutrients based on crop-specific needs and growth stages.
Develop and oversee environmental control strategies, programming and fine-tuning systems (HVAC, lighting, CO2 injection) to maintain optimal temperature, humidity, and Vapor Pressure Deficit (VPD).
Lead the integration and maintenance of horticultural lighting systems, including calculating DLI (Daily Light Integral), creating lighting maps, and optimizing spectrums for different crops and growth phases.
Spearhead the development and execution of Integrated Pest Management (IPM) programs, focusing on preventative measures, biological controls, and safe, effective intervention strategies.
Analyze sensor data from the growing environment and crop performance metrics to identify trends, diagnose issues, and make data-driven decisions to optimize yield, quality, and resource use.
Manage and troubleshoot complex automated systems within the facility, including seeding lines, transplanting robots, harvesting equipment, and conveyance systems.
Conduct research and development trials on new cultivars, growing techniques, substrates, and technologies to drive continuous improvement and innovation.
Develop, document, and train cultivation staff on Standard Operating Procedures (SOPs) for all technical and horticultural processes to ensure consistency and safety.
Play a key role in the design and commissioning of new facilities or the expansion of existing ones, providing expert input on layout, equipment selection, and system integration.
Proactively identify and resolve cultivation challenges, from nutrient deficiencies and disease outbreaks to equipment malfunctions, acting as the primary technical troubleshooter.
Manage the root zone environment, including substrate selection, and regular monitoring of pH, Electrical Conductivity (EC), and moisture levels to ensure plant health.
Create and maintain detailed records of crop cycles, environmental data, resource consumption, and yields to support forecasting, reporting, and strategic planning.
Collaborate closely with the Head Grower and cultivation team to align engineering initiatives with horticultural goals and provide technical support and training.
Evaluate and manage the consumption of key resources like water, energy, and nutrients, implementing strategies to improve sustainability and reduce operational costs.
Liaise with external vendors and contractors for equipment procurement, installation, and maintenance, managing relationships and ensuring project specifications are met.

Secondary Functions

Support the development and refinement of yield forecasting models by providing accurate technical and environmental data inputs.
Actively research and stay ahead of emerging technologies and trends in ag-tech, controlled environment agriculture, and horticulture to recommend future investments.
Contribute to the development of operational budgets by providing estimates for utilities, consumables, and maintenance related to horticultural systems.
Ensure all horticultural operations and systems comply with relevant environmental, health, and safety regulations.
Participate in cross-functional projects, collaborating with data science, operations, and business teams to achieve broader company objectives.
Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
