# of Openings:1

Allegiance Refining (operator of The San Antonio Refinery “TSAR”) operates by its three tenets:

Safety:
We aim for everyone to go home safely safely day and strive for an accident and incident-free workplace.

Stewardship:
We are stewards of the assets we operate and are committed to being safe and environmentally responsible.

Service:
We strive to provide first-class service to our customers.

The Maintenance & Reliability Manager is a leadership position reporting to the General Manager, with full accountability for the maintenance expense budget, work execution, and mechanical integrity.

The role pairs maintenance leadership — people, budget, craft execution, turnaround support with hands‑on ownership of the site’s reliability data and models. The position sets the tone for safe, compliant, reliability-centered operations at TSAR.

• Lead the maintenance organization to deliver the refinery’s process safety, personnel safety, environmental, reliability, and cost objectives.
• Own work management end to end — identification, prioritization, planning, scheduling, execution, and close-out.
• Drive schedule compliance, wrench time, backlog health, and rework reduction through measured performance and root cause resolution.
• Direct QA/QC of repairs; maintain job plans, repair procedures, and craft work standards.
• Manage spare parts strategy, critical spares inventory, and vendor/contractor performance.

• Use Newton™ platform (a quantitative engine that calculates probability of failure at the failure-mode level and aggregates asset-level risk into a live, facility-wide system model to drive day-to-day reliability and maintenance decision‑making, with direct ownership of modeling for non‑fixed assets (rotating, electrical, and instrumentation equipment)).
• Configure and tune models so assessments reflect actual operating conditions and observed equipment behavior.
• Validate model accuracy through structured quality checks and field verification; keep models and asset relationships current through the site MOC process.

• Analyze model output and maintenance history to identify bad actors, failure drivers, chronic cost centers, and data gaps; maintain a dynamic watchlist and mitigation plans for the top contributors to refinery risk and unplanned downtime.
• Optimize PM/PdM strategies, condition monitoring, and task intervals against quantified risk rather than convention; recommend maintenance intervals, repair‑versus‑replace decisions, upgrades, and stocking levels.
• Lead root cause analyses for mechanical and process equipment failures; drive corrective actions to closure and write findings back into the model.
• Produce Decision Support Packages for rotating equipment found deficient in design or at end of life, supporting the site capital intake and prioritization process.
• Identify operating practices that adversely affect asset life — operation outside design envelope, improper shutdown sequences, inventory workflow gaps — and partner with Operations to correct them.
• Own reliability and maintenance KPI reporting to the Refinery Leadership Team and ownership, including availability, MTBF, PM compliance, maintenance cost per barrel, and cost avoidance realized.

• Accountable for the site Mechanical Integrity program under OSHA PSM (29 CFR ) and RAGAGEP, including API 510, 570, 653, 580, and 581.
• Champion continuous improvement of Risk‑Based Inspection methodology and CML optimization and site Inspection.
• Maintain and annually review the PSM critical equipment list; keep Process Safety Information current and documented.
• Participate in MOC, PSSR, PHA, and incident investigation activities; resolve assigned PSM action items by due date.

• Develop and manage the maintenance operating budget and associated capital plan; support other departments in building spending plans that is aligned with reliability outlook.
• Track,…
