scoping, technical evaluation of suppliers, budgeting, and vendor selection,
ensuring timely procurement and alignment with operational
requirements.
• Engage in the design review and upgrade of water systems to meet
increasing service demands and environmental standards, including
automation enhancements and remote monitoring integration.
• Conduct risk assessments for mechanical and electrical systems to identify
potential vulnerabilities, and develop mitigation strategies in line with
business continuity planning.
• Prepare and submit detailed technical reports, project documentation, and
operational summaries to the Division Manager and relevant departments
for review, compliance reporting, and strategic planning.
• Carry out annual performance reviews, skills assessments, and continuous
development plans for staff to enhance workforce capability, productivity,
and succession readiness.
• Serve as a key liaison with regulatory agencies, engineering consultants,
and local government units during audits, compliance inspections, and
collaborative development projects.
• Champion sustainable engineering practices within the district by
promoting the use of energy-efficient equipment, water conservation
technologies, and eco-conscious operations.

• Supervised the day-to-day operations, repair, and preventive maintenance
of the water distribution system, ensuring all activities complied with the
Philippine National Standards for Drinking Water (PNSDW) and internal
quality protocols.
• Oversaw the installation, calibration, and upkeep of mechanical and
electrical systems within pump stations, reservoirs, and treatment facilities,
contributing to uninterrupted water supply for thousands of
concessionaires.
• Developed and enforced Standard Operating Procedures (SOPs) for system
maintenance and repair works, optimizing operational workflows and
reducing downtime incidents.
• Directed field teams during emergency response operations, such as pipe
bursts, power failures, and water quality incidents, ensuring swift
resolution and restoration of services.
• Led the technical training and onboarding of newly hired operators and
maintenance personnel, focusing on safety practices, troubleshooting
techniques, and operational best practices.
• Assisted the engineering department in site inspections, system
diagnostics, and data collection used for infrastructure planning and
capacity assessments.
• Played a key role in the deployment, testing, and commissioning of new
water treatment units, pump systems, and utility upgrades, ensuring
smooth integration with existing systems.
• Maintained accurate maintenance logs, service records, and incident
reports to support operational audits and performance reviews.
• Promoted a culture of safety, accountability, and continuous improvement
within the technical team.

• Operated, maintained, and optimized Surface Mount Technology (SMT)
production lines within a high-volume manufacturing environment,
ensuring operational efficiency, precision, and timely completion of
production schedules.
• Conducted daily inspection and performance monitoring of SMT
equipment, including screen printers, pick-and-place machines, reflow
ovens, and conveyors to minimize errors and machine downtime.
• Executed Total Preventive Maintenance (TPM) protocols across all assigned
machines, contributing to enhanced equipment reliability and an increase
in production output by reducing unplanned breakdowns.
• Supported the engineering department in diagnosing root causes of
electrical, mechanical, and software-related issues, implementing real-time
corrective actions to avoid production delays.
• Assisted in programming SMT machines and fine-tuning production
parameters to align with quality and productivity benchmarks set by the
process engineering team.
• Worked closely with Quality Assurance (QA) teams to ensure that
assembled printed circuit boards (PCBs) met client specifications, applying
corrective measures during inline audits.
• Participated in continuous improvement initiatives, identifying areas to
streamline workflows, improve machine setup times, and reduce material
wastage.
• Provided technical documentation including incident reports, maintenance
logs, and performance records, which were used for internal audits and
decision-making by engineering managers.
• Demonstrated strong teamwork and communication by coordinating
across production, QA, and engineering departments to meet daily and
weekly output targets.
