Head of Production

Our client is a licensed Colombian cannabis operator specializing in the cultivation, processing, and development of medical cannabis products. They are seeking a Head of Cultivation to own the day-to-day execution, performance, consistency, and continuous improvement of the cultivation operation, from propagation through harvest.

The Head of Cultivation combines strong plant science and cultivation knowledge with disciplined operational management. This is a hands-on leadership position requiring daily involvement in crop steering, environmental management, irrigation and fertigation, plant health, pest and disease prevention, labor management, production scheduling, data analysis, and quality control. The successful candidate identifies problems before they materially affect yield or quality, develops data-driven corrective actions, and ensures that cultivation teams consistently execute established SOPs, all within the company's GACP framework and chain of authority.

This role requires someone who can operate within a structured, GMP-aligned environment, following established protocols and leadership direction, including guidance from international technical partners, rather than operating independently based on informal growing experience alone. The primary objective of this position is simple: produce healthy, consistent, high-quality crops on schedule while maximizing yield, quality, labor efficiency, facility utilization, and overall profitability.

MUST HAVE

• 5+ years of experience in agronomic or commercial crop production roles, including cannabis cultivation experience.
• 2+ years of cannabis cultivation experience within a legal, licensed medical cannabis operation.
• Demonstrated experience leading cultivation teams.
• Advanced knowledge of irrigation, fertigation, and environmental crop management (EC, pH, VPD).
• Candidates must already hold the legal right to live and work in Colombia. Visa sponsorship and relocation assistance are not offered for this role.
• Fluency in Spanish, in addition to the required English proficiency, to support daily team leadership and on-site operations.

Core Responsibilities

Crop Management & Cultivation Execution

• Oversee the complete cultivation cycle: mother plant management, propagation and cloning, vegetative growth, transplanting, flowering, crop steering, and harvest preparation.
• Conduct regular walkthroughs of all cultivation areas to identify nutrient deficiencies or toxicities, irrigation issues, root-zone problems, environmental stress, pest or disease pressure, genetic abnormalities, and canopy inconsistencies.
• Develop and execute corrective action plans whenever crop performance deviates from established targets.

Environmental Management & Irrigation

• Establish, monitor, and maintain environmental targets (temperature, relative humidity, VPD, CO₂, light intensity and distribution, photoperiod) appropriate to each stage of plant development.
• Review environmental trend data rather than relying solely on instantaneous readings, and immediately investigate excursions that could affect crop health or quality.
• Develop and oversee irrigation and fertigation strategies: frequency, shot size, substrate drying targets between waterings, substrate EC and water content, feed and runoff EC and pH, adjusting based on plant demand rather than fixed schedules.
• Work with irrigation and fertigation personnel to ensure accurate nutrient mixing, proper dosing, and uniform, well-maintained irrigation systems.
• Develop and maintain nutritional programs for all stages of production, monitoring for deficiencies, toxicities, and root-zone imbalances.
• Maintain an aggressive preventative Integrated Pest Management (IPM) program, including scouting, preventative treatments, biological and cultural controls, and application rotations, in compliance with Colombian phytosanitary and cannabis regulations.
• Maintain strong biosecurity practices to prevent systemic pathogens and viroids, including clean mother stock, quarantine protocols, sanitation, and tool sterilization.
• Maintain a healthy genetic inventory, evaluating cultivars for yield, potency, terpene production, disease resistance, and commercial scalability.
• Oversee propagation performance, ensuring healthy plant counts on schedule and investigating deviations in rooting time, quality, or loss rates.
• Own flower-room execution from transplant through harvest: room loading, spacing, irrigation, trellising, defoliation, and harvest timing based on maturity and trichome development.

Data, Performance & Continuous Improvement

• Track production, quality, plant health, and operational indicators (grams per square meter, kilograms per harvest cycle, percentage of prem
