[Hiring] Building Efficiency Engineer @Cambio AI Inc.

Role Description

We're looking for a part-time Building Engineer contractor to join our Building Engineering team. This is a remote, flexible role well-suited for an experienced building engineer who wants to do meaningful technical work.

What You'll Do:

• 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.
• Execute 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.
• Review ML-generated ECMs (Energy Conservation Measures) for completeness, cost accuracy, and defensibility — correcting scope, energy savings estimates, and customer-facing comments as needed.
• Integrate PCA-sourced ECMs where applicable and apply cost override workflows with documented rationale.
• Participate in QA review — responding to flags with inline comments, escalating non-standard assumptions, and ensuring nothing is published without sign-off.
• Keep your RABL (Retrofit Analytics Building Log) tickets current — logging overrides, blockers, and status updates as analysis progresses.
• Report BSE bugs and tooling feedback through established channels to help improve platform quality.

Qualifications

• 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.

Requirements

• 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.
