Job brief

We are looking for a detail-oriented Energy Engineer to join our facilities and infrastructure team and lead our mission toward carbon neutrality. In this role, you will perform deep-dive data analysis on our site-wide consumption patterns to engineer innovative solutions that decrease our energy intensity. You will work closely with onsite maintenance crews, external contractors, and executive stakeholders to execute complex energy efficiency projects from design through commissioning. If you are passionate about technical problem-solving and sustainable engineering, we invite you to help shape our future energy strategy.

Key highlights

Perform ASHRAE Level II and III energy audits to identify technical inefficiencies and cost-saving opportunities within large-scale mechanical systems.
Develop detailed energy models using software such as Trane TRACE 700 or OpenStudio to simulate building performance and predict potential ROI.
Design and oversee the installation of Building Automation Systems (BAS) and HVAC upgrades to optimize real-time energy usage and comfort levels.
Execute Measurement and Verification (M&V) protocols following IPMVP standards to validate energy performance improvements and utility bill savings.

What is a Energy Engineer?

An Energy Engineer is a specialized technical professional focused on the design, analysis, and management of energy systems to improve operational efficiency and sustainability. By applying thermodynamic principles and advanced modeling software, an Energy Engineer assesses the performance of heating, ventilation, cooling, and power generation infrastructure. Their expertise is vital in helping organizations reduce carbon footprints, achieve LEED or ISO 50001 certification, and significantly lower long-term operational expenditures.

What does a Energy Engineer do?

An Energy Engineer conducts comprehensive energy audits to identify waste, models building performance using tools like eQUEST or EnergyPlus, and develops retrofit strategies for industrial facilities. They collaborate with MEP design teams and procurement managers to specify high-efficiency HVAC systems, smart building controls, and renewable energy integration projects. Furthermore, they perform M&V (Measurement and Verification) to validate savings and ensure that mechanical systems adhere to ASHRAE standards and local energy codes.

Demonstrated experience interpreting complex data sets in Excel, SQL, or specialized energy analytics platforms to drive operational strategy.
Deep understanding of thermodynamic cycles, heat transfer, and fluid mechanics as applied to industrial and commercial HVAC systems.
Proven capability to interpret electrical one-line diagrams, mechanical blueprints, and PID diagrams for facility-wide system modifications.
Ability to explain intricate technical energy saving concepts to non-technical stakeholders, including finance teams and building owners.
Hands-on experience with commissioning, retro-commissioning, and troubleshooting automated building control systems like Honeywell or Siemens Desigo.

FAQs

What does an Energy Engineer do on a daily basis?

An Energy Engineer balances time between field inspections and data analysis. Daily tasks typically include conducting onsite facility audits, reviewing BAS trends to diagnose system performance, coordinating with contractors on retrofit installations, and running simulations to test new efficiency ideas. They also spend significant time documenting results for regulatory compliance and financial reporting to show how energy improvements positively impact the bottom line.

What certifications are required to become an Energy Engineer?

While a bachelor’s degree in an engineering discipline is the foundation, industry-recognized certifications are essential for career advancement. The Certified Energy Manager (CEM) from the Association of Energy Engineers (AEE) is the industry gold standard. Other valuable credentials include the LEED Accredited Professional (LEED AP) for sustainable design, the Certified Measurement and Verification Professional (CMVP), and the PE license for those handling stamped engineering drawings.

How does an Energy Engineer improve operational efficiency?

An Energy Engineer improves efficiency by identifying 'low-hanging fruit'—such as fixing leaking compressed air lines or scheduling HVAC systems to match occupancy—as well as long-term capital projects. By using data-driven M&V protocols, they identify where systems are wasting power. They then implement sophisticated controls and high-efficiency equipment upgrades that reduce consumption without compromising the operational requirements of the facility.

What software do Energy Engineers use?

Energy Engineers rely on a specialized stack of tools to perform their work. This includes energy modeling software like eQUEST, EnergyPlus, and IESVE to predict building usage. They also work with Building Automation System (BAS) interfaces (like Tridium or Metasys) to monitor and control equipment. Additionally, mastery of Excel for advanced data analysis, as well as AutoCAD or Revit for reviewing design documentation, is standard for the profession.
