Position Requirements & Physical Demands

Industrial maintenance at a massive hydroelectric facility is both mentally engaging and physically demanding. To succeed, candidates must meet clear guidelines to ensure their safety and the safety of their team.

Critical Screening Elements

• Trainee III Screen-Out: You must show documented experience performing routine preventive maintenance on mechanical equipment, such as replacing worn bearings, filters, gaskets, and seals under supervision.
• Trainee IV Screen-Out: You must demonstrate the ability to perform scheduled repairs and overhauls on industrial machinery (pumps, gearboxes) and safely run standard shop tools like grinders and drill presses.

Physical Capabilities

• Stamina & Mobility: Requires extensive walking, standing, climbing vertical and inclined ladders, crawling, and working in tight or awkward spaces for long periods.
• Strength Requirements: Frequent lifting and carrying of equipment weighing up to 45 pounds. Operating large industrial valves and system components can require up to 75 pounds of pulling or turning force.
• Sensory Requirements: Excellent distant vision in each eye (corrective lenses permitted) and basic color differentiation are required to read fine calibrations and colored system lines. Normal conversational hearing (hearing aids permitted) is required for safety in noisy environments.

Environmental Conditions

Work is primary centered in the powerhouse but extends to outdoor intake structures and spillways, exposing employees to extreme climate variations. You will routinely encounter loud machinery noise, high-voltage areas, grease, fumes, and confined spaces. Wearing standard personal protective equipment (PPE)—including hard-hats, respirators, safety glasses, and ear protection—is mandatory.

Application Tips for Success

Applying for federal roles requires a careful and precise approach. To make sure your application passes the initial screening, keep these critical tips in mind:

1. Respect the Two-Page Rule: Your resume must be two pages or less. If your resume exceeds two pages, it will be automatically removed from consideration, and you will not receive an evaluation.
2. Quantify Your Work History: For every job listed, include your start and end dates (month and year), the exact name of the employer, your official job title, and the average hours you worked per week.
3. Use Clear, Action-Oriented Language: Do not rely on internal jargon or unexplained acronyms. Clearly describe the tools you used, the components you maintained, and the safety rules you followed.
4. Address the Screen-Out Element: Make sure your resume explicitly mentions tasks like changing seals and gaskets (for Trainee III) or overhauling gearboxes and threading pipes (for Trainee IV) to ensure you pass the system screens.
