About the Role
We are seeking a dynamic and motivated Senior CFD Specialist to advance our CFD practice at the intersection of fluid dynamics, building science, and human outcomes. This role applies technical mastery to real-world challenges, helping clients answer complex questions about airflow, contaminant transport, occupant comfort, and environmental performance. The ideal candidate brings strong technical expertise, sound judgment, and leadership capabilities to manage projects, mentor staff, and own client relationships.
Responsibilities
- Lead CFD model development using SimScale, Flovent, and related platforms for complex building types, evaluating thermal comfort, airflow, occupant health, and building envelope interactions.
- Model outdoor airflow dynamics, including exhaust re-entrainment, wind effects, contaminant dispersion, and thermal microclimate effects.
- Manage projects end-to-end, including scope, schedule, budget, billing, and risk identification.
- Review CFD models from junior staff, ensuring mesh quality, boundary conditions, turbulence modeling, and result interpretation.
- Establish and maintain quality control protocols and documentation standards.
- Lead client meetings and design reviews, translating simulation results into actionable guidance.
- Build and maintain client relationships, contributing to RFQ responses, proposals, and fee estimates.
- Mentor junior staff and support their development.
- Shape the CFD practice’s direction through tool selection, workflow development, market positioning, and thought leadership.
Requirements
- B.S. or M.S. in Mechanical Engineering, Aerospace Engineering, Civil/Environmental Engineering, or a closely related field required; advanced degree preferred.
- 8–10+ years of relevant experience in CFD modeling or building simulation applied to HVAC, building performance, or built environment applications.
- Experience across some combination of healthcare design, smoke control, contaminant transport, pathogen dispersion, outdoor airflow, laboratory environments, mission-critical facilities, or thermal comfort assessment.
- Proven track record managing project scope, schedule, budget, and client expectations in a consulting environment.
Skills
- Deep knowledge of CFD fundamentals, including turbulence modeling, mesh sensitivity, boundary conditions, solver selection, and practical application.
- Hands-on experience with SimScale and/or Flovent required; familiarity with other simulation platforms is a plus.
- Strong HVAC fundamentals, including heat transfer, airflow, and psychometrics.
- Strong verbal and written communication skills.
- Rigorous analytical judgment and critical thinking skills.
- Collaborative, client-ready, and team-oriented interpersonal skills.
- Demonstrated ability to think beyond the current project and contribute to service development.
