Description

  • Assess whether building analytics findings are valid and maintain the quality of the rules behind them.
  • Grow the rule library by converting open-ended charters into validated rules prioritized by impact.
  • Investigate building performance like an energy auditor, verify leads against data quality and site constraints, and turn findings into portfolio-wide rules.
  • Evaluate buildings, equipment, and points for trending based on potential savings.
  • Develop and apply measurement and verification (M&V) methods for each building and measure, including nonstandard IPMVP approaches.
  • Determine when insights are ready to become controls and implement them safely through the BACnet priority array.
  • Lead findings reviews with customer engineering and facilities teams.
  • Share customer learnings with Product and Engineering.
  • Develop grading playbooks and refine them when software grading is inaccurate.
  • Review and refine rules and proposals.
  • Write reproducible, point-referenced defect reports that distinguish root causes from symptoms.
  • Calculate savings using multiple methods and review estimates with the principal engineer.
  • Develop new M&V methods when existing approaches are unsuitable.
  • Assess whether findings are ready to guide controls.
  • Prioritize and carry out ambiguous rule-building charters.
  • Expand review capacity through rule-level reviews, sampling, clustering, and AI-assisted grading.
  • Spot-check software graders and monitor disagreements.
  • Lead findings reviews and engineering deep dives with prospective and current customers.

  • Ability to validate findings using trend and building data.
  • Hands-on time-series data analysis using AI agents, analytics platforms, or code.
  • Ability to implement controls through the BACnet priority array, including write priorities, relinquish defaults, and operator override conflicts.
  • Ability to write sequences of operation or control strategies based on ASHRAE Guideline 36.
  • Working expertise with air handling units, variable air volume systems, and terminal units, plus familiarity with central plants and hydronic systems.
  • Ability to apply IPMVP in operating buildings and map BACnet points to M&V variables.
  • Experience leading technical reviews with customer engineering or facilities staff.
  • Proof of eligibility to work in the United States.
  • Successful completion of a background check upon employment.
  • Ability to read reports and computer monitors; hear well enough to communicate; sit and stand for extended periods; use keyboard, tablet, and phone systems; and lift, push, and pull at least 75 pounds.
