Building Efficiency Engineer

What You'll Do

You'll run end-to-end retrofit analyses on commercial properties using Cambio's proprietary toolset, contributing directly to the decarbonization plans we deliver to our customers. Day-to-day, this includes:

• Executing BSE (Building Science Engine) workflow analyses on assigned properties — reviewing PCA reports, utility data, equipment inventories, and site visit notes to configure and run each analysis
• Reviewing ML-generated ECMs (Energy Conservation Measures) for completeness, cost accuracy, and defensibility — correcting scope, energy savings estimates, and customer-facing comments as needed
• Integrating PCA-sourced ECMs where applicable and applying cost override workflows with documented rationale
• Participating in QA review — responding to flags with inline comments, escalating non-standard assumptions, and ensuring nothing is published without sign-off
• Keeping your RABL (Retrofit Analytics Building Log) tickets current — logging overrides, blockers, and status updates as analysis progresses
• Reporting BSE bugs and tooling feedback through established channels to help improve platform quality

What We're Looking For

• Background in mechanical, electrical, or building engineering — familiarity with commercial HVAC systems, energy audits, and PCAs strongly preferred
• Comfort working within proprietary software toolsets and structured workflows
• Strong attention to detail and engineering judgment — you'll be making calls on ECM scope and cost that end up in front of customers
• Ability to work independently, flag blockers early, and communicate clearly in a remote async environment
• Prior experience with building energy modeling, retrofit analysis, or sustainability consulting is a plus

The Details

• Type: Part-time independent contractor; possibility for FT conversion dependent on location
• Location: Fully remote in Canada or US
• Hours: 10-20 hours per week
• Deliverables-based: Work is scoped per property with clear acceptance criteria
