Physical Requirements

Employees working in naval industrial environments, whether shipboard or pierside, must meet certain physical requirements to safely perform essential job functions. Individuals must be capable of standing and walking for extended periods, often on uneven, wet, or slippery surfaces, and must be able to climb vertical ladders, stairs, and steep inclines while carrying tools or equipment. The position requires the ability to work in confined spaces with limited ventilation and restricted movement, including crawling through narrow passageways and working in overhead or below-deck areas.

Workers must possess sufficient manual dexterity and grip strength to operate hand and power tools, manipulate controls, and handle materials weighing up to fifty pounds on a regular basis, with occasional lifting of heavier objects with assistance. The role demands the physical ability to bend, stoop, kneel, crouch, and reach overhead repeatedly throughout the workday. Adequate vision is necessary to read technical manuals, identify color-coded systems, and detect safety hazards, while hearing capability must be sufficient to perceive warning signals, alarms, and verbal communications in noisy environments, with or without hearing protection.

Employees must be able to work in varying environmental conditions including extreme temperatures, high humidity, direct sunlight, and exposure to weather elements. The position requires the stamina to work extended shifts and the balance and coordination necessary to maintain stability on moving vessels. Workers must be capable of responding quickly to emergency situations, including evacuating confined spaces and moving to emergency stations. Reasonable accommodations may be available for qualified individuals with disabilities who can perform the essential functions of the position with or without such accommodations.

Desired Qualifications

• Hands-on experience with Siemens (S7-1500, TIA Portal, etc.) and/or Allen Bradley (ControlLogix, RSLogix 5000) PLC platforms

• Strong understanding of PLC logic, control strategies, and ladder/structured text programming Experience supporting and troubleshooting networked, IP-based systems both onsite and via distance support
• Proficient in reading and interpreting electrical schematics and control system drawings
• Experienced in using test and diagnostic tools specific to industrial and PLC-based systems
• Basic knowledge of network communications as applied to control systems (Ethernet/IP, Profinet, etc.)
• Experience programming with multiple IEC 61131-3 languages (e.g., ladder logic, structured text)
• Experience with SCADA or HMI development
• Background in hardware upgrades and modernization of legacy embedded PLC systems
• Experience with SIM/STIM development
