We are about Building Energy Performance. Summary/Primary Role: This role is the go-to engineering resource for geothermal innovation at Brightcore, sitting within the Geothermal business unit. This person owns the engineering analysis behind the Innovation roadmap — evaluating new geothermal products and services at every stage of development, from first-light technical feasibility and customer value proposition work, through prototyping and experimentation, to go-to-market testing and full product rollout and scale-up. The role spans multiple concurrent roadmap items at different points in the development chain, unified by rigorous engineering analysis of novel approaches to geothermal heating and cooling.  Principal Duties & Responsibilities: (Management may amend or assign duties and responsibilities to this job at any time) Geothermal Innovation Engineering  * Design innovative geothermal heating and cooling solutions, evaluating detailed HVAC, fluid flow, and geothermal modeling for novel approaches. * Analyze heat transfer and fluid dynamics, and evaluate the performance and efficiency of heat pumps, boilers, chillers, and related HVAC equipment. * Serve as the go-to technical resource across the Innovation team for geothermal engineering questions. Technical Feasibility & Concept Development  * Evaluate technical feasibility and customer value proposition for new geothermal innovation roadmap items, from first-light concepts through detailed design. * Develop techno-economic analyses (TEA) and initial design concepts for novel geothermal products and services. Prototyping & Experimentation  * Lead prototyping efforts spanning desktop TEA models and lab-based physical prototypes to validate new solutions. * Design and run experiments on existing systems to generate performance data and test hypotheses. Product Development & Go-to-Market Support  * Translate engineering analysis into product requirement documents (PRDs) for engineering, product, and business development teams. * Create go-to-market test materials and technical collateral supporting customer-facing pilots. * Support initial customer engagements and full product rollout and scale-up as roadmap items mature into commercial offerings. Cross-Functional Collaboration  * Partner with the Brightcore EDGE monitoring team, BCE Design engineering, and business development across the innovation pipeline. * Prepare drawings, calculations, and study drafts for review by licensed professional engineers  * All other duties and projects as assigned. Qualifications: * B.S. in Mechanical Engineering or related field. * 3–5 years in HVAC, data center design & operation, hydronic, geothermal, or mission-critical mechanical design and analysis. * Strong grounding in heat transfer, fluid dynamics, and thermodynamics; comfort reasoning through equipment performance metrics (COP, EER, approach temperatures, heat transfer rates). * Working proficiency with energy/load modeling tools (e.g., TRNSYS, EnergyPlus, HAP, or equivalent) and Excel-based engineering models. * Ability to carry ambiguous concept work — from first-light feasibility through prototype to product requirement — to a defensible, documented result without heavy supervision. * Fluent with AI tools. * Ability to do basic coding in python, or quickly come up the learning curve. Supervisory Responsibility:  * This position does not have supervisory responsibility. Expected Hours of Work & Compensation:  An employee is expected to work a minimum of forty (40) hours per week.
