Execute complex start-up, shutdown, and emergency procedures in a safe, efficient, and timely manner to maintain system stability and minimize operational downtime.
Strictly adhere to, and expertly perform, Lockout/Tagout (LOTO) procedures for equipment isolation to guarantee personnel safety during all maintenance, service, and repair activities.
Respond promptly and effectively to all plant alarms, systematically troubleshoot operational issues, and take decisive corrective actions to return systems to a normal, stable condition.
Maintain detailed and accurate logs, records, and reports of plant operations, maintenance activities, and environmental data using both digital and manual systems.
Perform preventative and minor corrective maintenance tasks, including equipment lubrication, system adjustments, and cleaning of components to ensure optimal performance and extend asset longevity.
Collect and analyze process samples for water chemistry, steam quality, and other process fluids, making precise chemical feed adjustments as necessary to protect equipment integrity and efficiency.
Coordinate and communicate effectively with maintenance, engineering, and management personnel regarding plant status, equipment issues, and immediate operational needs.
Ensure all plant operations are conducted in strict compliance with federal, state, and local environmental regulations, as well as all company safety policies and procedures.
Safely operate heavy equipment such as forklifts, man-lifts, and small cranes to support material handling and maintenance activities across the facility.
Expertly handle and transfer hazardous materials and plant chemicals, following all Safety Data Sheet (SDS) guidelines and wearing appropriate Personal Protective Equipment (PPE) at all times.
Assist in the development, review, and revision of Standard Operating Procedures (SOPs) to reflect industry best practices and continually improve plant safety and efficiency.
Actively participate in all safety meetings, Job Hazard Analyses (JHAs), and mandatory training sessions to foster and contribute to a strong, proactive safety-first culture.
Monitor and optimize overall plant performance by analyzing trends in operational data and making strategic adjustments to control parameters for maximum efficiency and output.
Provide work direction and vigilant oversight to contractors on-site, ensuring their unwavering adherence to company safety protocols and work quality standards.
Manage brine and non-condensable gas extraction and injection systems to sustain steam production and optimize resource utilization from the geothermal reservoir.
Conduct regular fire and safety system inspections, including checks on fire pumps, hydrants, and emergency response equipment, to ensure constant site readiness.
Utilize the Computerized Maintenance Management System (CMMS) to generate work orders, document maintenance history, and manage critical spare parts inventory.
Isolate, test, and de-energize electrical systems, including high-voltage switchgear and motor control centers (MCCs), in preparation for maintenance tasks.
Train, mentor, and guide junior operators and technicians, sharing expert knowledge of complex plant systems and operational best practices to build team capability.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis to troubleshoot performance issues.
Contribute to the organization's operational excellence and continuous improvement initiatives.
Collaborate with engineering and maintenance teams to translate operational needs into actionable projects.
Participate in sprint planning and agile ceremonies for plant outage and project management.
