Pre-construction Mechanical Estimator in Texas at Overwatch Mission Critical

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 services 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.

This role is designed to lead and oversee all mechanical estimating and preconstruction activities for design-build data center projects delivered under negotiated open Guaranteed Maximum Price (GMP) contracts. The primary goal is to provide budget transparency and ensure project execution aligns with evolving design timelines.

The ideal candidate must be able to act as a bridge between design development and real-time cost modeling. They are responsible for establishing a reliable GMP while collaborating closely with clients and trade partners to influence system selection and optimize costs.

For roles that require on-site presence or travel between work locations as an essential function of the position, candidates must possess and maintain a valid driver’s license appropriate for the role and be eligible to operate a motor vehicle in accordance with applicable laws.

Demonstrated ability to communicate effectively in a professional work environment, including preparing written reports and documentation, conveying information clearly to team members, clients, and stakeholders, and responding appropriately to verbal and written communications related to job duties.

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.

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 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.

Overwatch Construction offers a competitive salary and benefits package, including health insurance, dental insurance, vision insurance, life insurance, 401(k) retirement plan and paid time off. Relocation assistance is available to support candidates transitioning to the location.

OVERWATCH is committed to creating a diverse work environment and is proud to be an Equal Opportunity Employer. OVERWATCH considers candidates regardless of race, color, religion, sex, sexual orientation, gender identity, national origin, disability or veteran status.
