Geothermal Mechanical Engineer Jobs (NOW HIRING)

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.
