Core Responsibilities

Primary Functions

Operate, monitor and control industrial dry kilns (steam, gas, electric or wood-fired) to achieve target moisture content and drying profiles for multiple wood species and thicknesses, adjusting temperature, humidity, airflow and cycle times as required.
Read, interpret and implement drying schedules and kiln programs to meet customer specifications and production plans, including species-specific curves, green lumber conditions, and end-use tolerances.
Use moisture meters and oven-dry test procedures to measure lumber moisture content across loads, log results, and adjust kiln parameters to ensure consistent, conforming product.
Program, troubleshoot and optimize computerized kiln controllers and PLC-based systems, making informed adjustments to heat-up, equalization and conditioning stages to reduce defects and cycle times.
Load and unload kilns safely and efficiently using forklifts, overhead cranes or team lifts, staging loads to maximize kiln utilization and minimize handling damage.
Inspect lumber before, during and after drying for defects such as checks, splits, honeycombing, mildew and discoloration; document nonconformances and coordinate rework or special handling as required.
Maintain detailed kiln records including drying schedules, time-temperature-humidity logs, moisture readings, production counts and energy usage for batch traceability and continuous improvement.
Perform routine preventive maintenance and basic repair on kiln components (fans, blowers, burners, steam traps, valves, sensors, dampers) and escalate complex mechanical or electrical issues to maintenance teams.
Calibrate and validate kiln instrumentation including moisture meters, thermocouples, humidity sensors and pressure gauges to ensure accurate process control.
Follow all lockout/tagout procedures, confined-space entry protocols and other safety procedures while performing kiln entry, cleaning or maintenance activities.
Manage fuel and energy systems tied to kiln operation, monitoring fuel levels, burner performance, combustion air and emissions controls to support energy efficiency and environmental compliance.
Coordinate daily with sawmill production, grading, and shipping teams to prioritize kiln loads, meet delivery deadlines and manage inventory of dried lumber to minimize storage bottlenecks.
Execute controlled conditioning and cooling sequences at the end of drying cycles to relieve internal stresses and reduce warping or checking in finished lumber.
Implement and document quarantine or re-drying procedures for loads that fail to meet moisture or quality specifications, including identification, segregation, and corrective action plans.
Participate in root-cause analysis for recurring drying defects and collaborate with production, quality and maintenance to update schedules, fixtures or process controls to reduce scrap and rework.
Maintain housekeeping inside and around kilns—removing fines, debris and dust that can affect kiln airflow, sensor readings or create fire hazards.
Train and mentor junior operators or temporary staff on safe kiln operation, moisture measurement techniques, basic troubleshooting and documentation expectations.
Ensure compliance with environmental permits and local regulations related to emissions, condensate handling, wastewater or chemical treatments used in kiln operations.
Order and maintain inventory of consumable supplies for kiln operations (seals, gaskets, sensor replacements, lubricants, desiccants) and provide input to procurement on critical spares.
Monitor and report energy consumption metrics and suggest workflow, scheduling or equipment changes to reduce fuel use, electrical load and cost per board foot dried.
Apply inspection criteria and grading knowledge to segregate premium vs. utility lumber and communicate quality status to sales and production planners.
Perform controlled chemical or preservative treatments as part of kiln schedules when required (e.g., anti-stain, fungicide) in accordance with safety data sheets and environmental controls.
Keep accurate shift handover notes and digital logs to ensure continuity between operators and enable traceability of kiln conditions and decisions.
Participate in safety audits, continuous improvement projects (kaizen), and implementation of best practices to improve throughput, quality and workplace safety.

Secondary Functions

Assist maintenance and engineering teams with root-cause investigations and implementation of corrective actions for recurring kiln system faults.
Support inventory control by tracking dried lumber volumes, identifying staging needs and notifying logistics of priority shipments.
Help develop and update standard operating procedures (SOPs), drying recipes and operator checklists to reflect process improvements and regulatory changes.
Provide on-the-job training and mentoring to new operators, including safe use of forklifts, kilns, moisture meters and controller interfaces.
Participate in site safety committees, report hazards, and assist with risk assessments for kiln-related tasks.
Compile daily and weekly performance reports (production, quality rejects, energy usage) to support operations management decisions.
Assist with emergency response procedures for kiln-related incidents including fires, steam leaks or mechanical failures until maintenance/management arrive.
Contribute to cross-functional projects to implement new kiln technologies, retrofits or energy-saving upgrades.
Support packing and staging teams during peak shipping periods by ensuring dried product is staged according to shipping schedules.
Participate in scheduled training for regulatory compliance (OSHA, environmental rules, confined space, LOTO).
