Intern, Utilities Engineering

Location: San Antonio, Texas

Job Description

The Utilities Engineering Intern will support the safe, reliable, efficient, and compliant operation of utility systems serving a large Constellation Brands brewery. Working with Utilities Engineering, Operations, Maintenance, Reliability, Process Safety, and brewery production teams, the intern will complete field-based engineering assignments and improvement projects across thermal, refrigeration, compressed-gas, water, wastewater, and electrical infrastructure.

The role combines structured technical learning with practical project execution. Assignments may include equipment performance analysis, utility-balance development, preventive-maintenance improvement, documentation updates, energy and water conservation, and capital-project support. All work will be performed under the direction of qualified site personnel and in accordance with applicable safety, environmental, electrical, and process-safety requirements.

Utilities Engineering Scope

Boiler and steam systems: boilers, deaerators, feedwater systems, water chemistry, fuel trains, blowdown, condensate return, steam distribution, traps, pressure-reducing stations, and heat recovery.

Ammonia refrigeration: compressors, condensers, evaporators, pumps, vessels, oil management, controls, relief systems, ventilation, detection, and Process Safety Management support.

Compressed air: plant and instrument-air compressors, dryers, receivers, filtration, distribution, leak reduction, pressure optimization, and specific-power performance.

Carbon dioxide systems: CO2 recovery, purification, liquefaction, storage, vaporization, compressors, distribution, quality monitoring, and loss reduction.

Well water and water treatment: wells, pumps, raw-water conveyance, filtration, softening, reverse osmosis or other treatment processes, chemical feed, storage, and distribution.

Wastewater treatment: collection and lift stations, screening, equalization, pH control, anaerobic and aerobic treatment, clarification, sludge handling, biogas interfaces, discharge compliance, and water-reuse opportunities.

Electrical utilities: low-, medium-, and high-voltage distribution; substations; transformers; switchgear; motor control centers; protective devices; emergency generation; grounding; power quality; and electrical safety.

Key Responsibilities

Support engineering and reliability projects for utility systems without independently operating, energizing, isolating, or adjusting equipment unless specifically trained, authorized, and supervised.

Collect and validate field data from operator rounds, control systems, historian trends, meters, laboratory results, maintenance records, and equipment nameplates.

Develop or update utility mass and energy balances, equipment inventories, system one-lines, piping and instrumentation diagrams, process-flow diagrams, operating envelopes, and equipment criticality information.

Analyze performance indicators such as boiler efficiency, steam-to-fuel ratio, condensate return, refrigeration energy intensity, compressor specific power, compressed-air leakage, CO2 recovery yield, water use, wastewater loading, electrical demand, power factor, and system availability.

Assist with equipment troubleshooting and root-cause analysis using trend review, field observations, maintenance history, cause-and-effect logic, and structured methods such as 5 Whys or fishbone analysis.

Support preventive and predictive maintenance improvements, including task review, job-plan development, spare-parts identification, condition-monitoring opportunities, and recurring-failure elimination.

Participate in scoped improvement projects from problem definition through data collection, alternatives analysis, estimate development, implementation planning, commissioning support, and benefit verification.

Identify opportunities to reduce energy, water, chemical use, CO2 losses, wastewater loading, and greenhouse-gas emissions while protecting product quality, capacity, and reliability.

Prepare clear technical reports, calculations, presentations, standard work, training materials, and final recommendations for engineering and operations leadership.

Participate in the corporate intern program, including senior-leader meetings, brewery tours, rotation days, team-building activities, and a final project presentation.

Safety, Environmental, and Compliance Expectations

Follow brewery safety rules, permit systems, personal protective equipment requirements, and field-access controls at all times.

Support, but do not independently perform, work governed by lockout/tagout, energized electrical work, confined-space entry, hot work, line breaking, or ammonia-system intervention.

Gain practical exposure to relevant programs such as OSHA Process Safety Management for ammonia refrigeration, EPA Risk Management Program requirements, electrical safe-work practices, water and wastewater permit compliance, management of change, pre-startup safety review, and emergency response.

Immediately report unsafe conditions, environmental concerns, abnormal utility-system conditions, and data-quality issues to the assigned supervisor.

Basic Qualifications

Currently pursuing a bachelor’s degree in Mechanical, Chemical, Electrical, Environmental, Industrial, Energy, or a closely related engineering discipline.

Completed junior year of the bachelor’s program before the internship start date.

Minimum cumulative GPA of 3.0.

At least 21 years of age as of 5/17/27

Working knowledge of Microsoft Excel, Word, and PowerPoint.

Ability to read and interpret technical drawings, engineering calculations, equipment data, and operating trends with coaching.

Strong analytical, problem-solving, written-communication, and verbal-communication skills.

Valid passport and ability to travel with team members to breweries in Mexico for trips typically lasting 2 to 3 days.
