About Overwatch Construction
Overwatch is a service-disabled Veteran-owned small business (SDVOB) certified through the national veterans business development council (NVBDC), offering construction professional services, talent acquisition, and general contractor for the mission-critical infrastructure industry. Our mission is the construction and management of state-of-the-art data centers with the precision and reliability this industry demands. From high-end engineers to seasoned professionals, we deploy the people you need to get your data center off the ground. At Overwatch, it's more than a job. It's purpose.
Physical Requirements and Work Environment
This position operates primarily in an active data center construction environment, encompassing both indoor and outdoor work settings. The role requires the physical ability to perform essential job functions safely and effectively in a dynamic environment that includes ongoing construction activity and evolving site conditions.
The work environment includes areas and temporary structures owned, leased, or controlled by third parties over which Overwatch may have limited or no control. Because the project remains under construction, certain areas of the site — including access routes, staging zones, and temporary structures — may not yet be fully ADA-compliant until construction is complete or those third-party areas are finalized.
Physical Requirements:
- Must be able to walk, stand, stoop, twist, bend, and climb stairs or ladders for extended periods while navigating uneven, unpaved, or obstructed terrain.
- Must be able to lift, carry, push, or pull up to 50 pounds on an occasional basis.
- Must be able to drive between job sites and access all areas of an active construction zone, including raised platforms, scaffolding, and confined spaces.
- Must be able to tolerate exposure to outdoor weather conditions, dust, and construction-related noise, vibrations, and odors.
- Must be able to communicate effectively with contractors, engineers, and site personnel, and maintain situational awareness in high-activity environments.
- Personal protective equipment (PPE), including hard hats, safety vests, hearing protection, and steel-toe boots, is required.
- Must have sufficient visual acuity to read drawings, specifications, and safety signage, and to observe site activity.
Work Environment:
Work is performed primarily in and around active construction areas, which may include unfinished buildings, temporary field offices, staging areas, and partially completed infrastructure. These locations may contain uneven surfaces, limited accessibility, and other conditions typical of construction projects prior to final completion. Overwatch does not control and cannot modify accessibility conditions within areas, facilities, or temporary structures owned or managed by third parties.
Reasonable Accommodation:
Reasonable accommodations may be made to enable qualified individuals with disabilities to perform the essential functions of this position, provided such accommodations do not create safety hazards, impede essential mobility within active work zones, or require modification of facilities not owned or controlled by Overwatch.
