The Automation Technician is the operational linchpin ensuring the continuous, compliant, and efficient performance of a cannabis facility's most valuable assets: its production and extraction equipment. In an industry where precision and documentation are paramount for licensure, this role transcends traditional maintenance. The technician is a master of electromechanical, pneumatic, and control systems, responsible for the uptime of everything from supercritical CO2 extractors to high-speed robotic packaging lines. They operate at the intersection of hardware and software, diagnosing complex faults, performing preventative maintenance, and calibrating sensitive instruments. Their work directly guarantees that every product, from a precisely dosed edible to a perfectly filled vape cartridge, meets exacting quality standards and that every action is meticulously documented for state regulators. This position is fundamental to the organization's ability to scale production while maintaining unwavering compliance in a dynamic legal environment.
The day's operations begin with a review of the Computerized Maintenance Management System (CMMS) and the production schedule. The first priority is the pre-flight check of the primary extraction system, a closed-loop butane hash oil (BHO) extractor located in a Class 1, Division 1 rated room. The technician verifies the functionality of methane sensors and emergency ventilation systems before powering up the unit. They inspect pneumatic valve actuators, check the levels of the heat transfer fluid, and confirm the PLC is communicating with all sensors. This documented start-up procedure is a strict requirement for both safety and state compliance, ensuring the highly volatile solvent is managed correctly.
An alert comes from the packaging floor. The automated pre-roll machine is faulting, reporting an inconsistent weight error. The technician proceeds to the machine, observing several cycles to understand the failure mode. Using the HMI, they access the diagnostic screen, which points to a specific servo motor responsible for tamping the cannabis flower. After performing a proper lockout/tagout procedure to de-energize the machine, they inspect the motor and its mechanical linkage. They discover a loose coupling, causing intermittent positioning errors. The coupling is tightened to the manufacturer's torque specification. The technician then runs a calibration routine through the HMI, using certified weights to validate the scale's accuracy. All steps, from the initial fault to the corrective action and final calibration, are logged in the CMMS with timestamps and signatures, creating a complete audit trail.
Midday is allocated to scheduled preventative maintenance. Today's task is servicing the wiped-film distillation unit used for producing high-purity THC distillate. The technician disassembles the main wiper basket, inspecting the delicate rolling film wipers for wear. They replace vacuum pump oil, clean and inspect all glass components for microfractures, and calibrate the temperature and pressure sensors against certified standards. This proactive work prevents catastrophic vacuum leaks or temperature fluctuations that would ruin the valuable oil being processed and cause significant production delays.
The afternoon focus shifts to a process improvement project. The technician has been analyzing data from the SCADA system, which revealed that the automated edible depositor line experiences a minor slowdown every hour, related to the temperature of the holding tank. They collaborate with the Head of Production to propose a small logic change in the PLC to optimize the heating element's duty cycle. After getting approval, they back up the current PLC program, implement the change, and monitor the line for the next hour. The data confirms the adjustment has stabilized the temperature and eliminated the slowdown, increasing the line's overall equipment effectiveness (OEE). The change is formally documented through the facility's change control process. The day concludes with a final review of all open work orders and a handover to the next shift, ensuring seamless operational continuity.
The Automation Technician's duties are structured around three pillars of operational excellence:
The Automation Technician directly influences key business performance metrics through the following mechanisms:
| Impact Area | Strategic Influence |
|---|---|
| Cash | Avoids significant fines from state cannabis control boards by ensuring all automated equipment operates and logs data in full compliance with regulations. |
| Profits | Directly increases revenue-generating output by maximizing equipment uptime and minimizing unplanned downtime on critical production and packaging lines. |
| Assets | Extends the operational lifespan and preserves the value of multi-million dollar capital equipment through rigorous preventative maintenance and expert repairs. |
| Growth | Creates a scalable production model by ensuring automation reliability, allowing the company to increase output to meet market demand without proportional increases in labor. |
| People | Enhances operator safety through diligent maintenance of machine guarding and safety circuits. Improves morale by providing reliable and efficient equipment. |
| Products | Guarantees product consistency and quality through precise calibration of depositors, fillers, and scales, ensuring every unit meets specifications for dosage and weight. |
| Legal Exposure | Mitigates the risk of product liability claims and recalls by maintaining a complete and defensible history of equipment maintenance, calibration, and validation. |
| Compliance | Ensures that all production processes controlled by automation are executed precisely as defined in approved SOPs, maintaining a constant state of audit-readiness. |
| Regulatory | Provides the technical expertise to adapt and validate equipment to meet new state regulations concerning product testing, child-resistant packaging, or labeling requirements. |
Reports To: This position typically reports to the Maintenance Manager, Head of Engineering, or Director of Manufacturing Operations.
Similar Roles: This role is often aligned with titles such as Controls Technician, Mechatronics Technician, or Instrumentation & Controls (I&C) Specialist. In other industries, it may be known as an Electro-Mechanical Technician or a Field Service Engineer. Within cannabis, the Automation Technician title specifically emphasizes the responsibility for high-throughput, compliant production systems, distinguishing it from general facilities maintenance roles.
Works Closely With: This position requires constant collaboration with the Extraction Manager, Packaging Supervisor, and Quality Assurance Manager. They also interface directly with equipment operators to understand performance issues and with the engineering team to plan upgrades and new installations.
Mastery of this role requires hands-on proficiency with a diverse range of industrial technologies:
Success in this role is built on experience from other highly automated and regulated industries:
The role demands a unique combination of technical and professional attributes:
