Energy Modeler​/Building Strategist

Energy Modeler / Building Performance Strategist

High-Performance Design | Decarbonization | Regenerative Practice

Little, one of the nation's most progressive design firms, is looking for a design-oriented building performance professional who understands energy modeling as more than compliance, calculation, or post-rationalization. We are looking for someone who can help project teams ask better questions earlier, test bold ideas with rigor, and use data to move our integrated process toward higher-performing, lower-carbon, regenerative outcomes.

This role is ideal for an electrical engineer, mechanical engineer, architectural engineer, building scientist, energy modeler, or performance strategist who is comfortable working at the edge of performance driven design. We are looking for a self‑led individual who deeply understands systems thinking and the greater opportunities toward integrating our work with living places through better design decisions; challenging assumptions, quantifying risk, and translating technical analysis into clear direction for architects, engineers, designers, clients, and consultants.

This person may be located in any of Little's office location’s however Orlando, FL is preferred.

Care: Care passionately about your clients, your work, and the people working beside you.

Stretch: Stretch your imagination, your ambition, and your potential.

Spark: Spark a spirit of excitement, discovery, and possibility in everyone around you.

You are curious, analytical, and persuasive. You know that data matters, but you also know that data only creates impact when people understand it and act on it.

You bring a strong foundation in building science and a desire to improve building performance through thoughtful, data‑driven analysis. You are comfortable developing energy models for early‑stage exploration as well as more detailed design‑phase studies, and you know how to document assumptions clearly so teams can trust the results.

You have a deep level of experience understanding building systems performance, commissioning outcomes, and tracking operations and their impacts on energy use and can translate that into credible energy models that reflect real‑world operational scenarios and can show confirmed data showing energy model results track through actual building performance within +/- 1‑2 EUI on average. Better yet, you are able to show an understanding of skewed results, the reasons behind the variances, and how your work translated into more accurate results moving forward based on incorporating that learned experience.

You are willing to question default approaches. You can evaluate unconventional strategies without being reckless. You understand that innovation in design requires both imagination and evidence.
