Specializing in mechanical, electrical, plumbing (MEP), JB&B has contributed to some of the most iconic buildings.\nIn October 2025, JB&B joined forces with Trinity Consultants, a global consulting firm focused on the natural and built environments. JB&B now operates within Trinity's Built Environment division, combining its deep expertise in high-performance building systems with Trinity's strengths in acoustic design, facility operations, commissioning, and technology strategy.\nThis strategic merger expands JB&B's capabilities and offers employees:\nAccess to a broader portfolio of international projects and clients\nEnhanced career mobility across Trinity's global network\nInterdisciplinary collaboration with experts in sustainability, environmental science, and digital infrastructure\nAbout the Role:Our CFD practice sits at the intersection of fluid dynamics, building science, and human outcomes: How do pathogens travel through a hospital corridor? Why is a rooftop exhaust system pulling its own exhaust back in? Is that outdoor terrace actually going to be comfortable? We're looking for a CFD Specialist who gets energized by those questions. Someone who can build a rigorous model, but who also has the instincts to know when the model is telling you something real - and the communication skills to translate that into guidance a design engineer or client can actually act on. This is a role on a small, focused team with direct impact on some of the most technically interesting building projects in the country. You'll work closely with our HVAC design engineers as an embedded technical resource, and directly with clients on projects where the stakes - occupant comfort, energy performance, and occupant health- are high.\nKey Responsibilities:\nModeling & Analysis\nDevelop and execute CFD (computational fluid dynamics) models using the latest software and related platforms to support HVAC design decisions across a wide range of building types\n\nEvaluate thermal comfort conditions for occupants - accounting for airflow patterns, surface temperatures, radiant effects from glazing, solar gain, and more\n\nModel outdoor airflow dynamics: exhaust re-entrainment, equipment air intake/discharge, wind effects at building openings\n\nSimulate particulate and contaminant dispersion - pathogens, smoke, odors - in occupied spaces including critical environments (ORs, isolation rooms, labs)\n\nAnalyze thermal microclimate effects from heat rejection sources such as heat pumps, generators, and cooling towers\n\nCollaboration & Problem-Framing\nPartner with JB&B's HVAC design engineers early in the design process to understand the real problem being solved - not just model what's handed to you\n\nHelp engineers and clients ask better questions; bring CFD insight to the table before problems become costly to fix\n\nServe as an internal technical resource and thought partner for the broader engineering team\n\nDeliverables & Communication\nProduce clear, well-organized simulation results with actionable recommendations\n\nDevelop presentation materials - visualizations, reports, executive summaries - that make complex fluid dynamics legible to non-specialists\n\nContribute to proposals, technical papers, and thought leadership content that elevates JB&B's reputation in building performance simulation\n\nMinimum Qualifications:\nB.S. or M.S. in Mechanical Engineering, Aerospace Engineering, Civil/Environmental Engineering, or a closely related field. Advanced degree preferred.\n\nProfessional licensure or certifications are not required; PE/EIT or relevant building science credentials are a plus.\n\n4+ years of relevant experience in CFD modeling, building simulation, or computational fluid dynamics applied to HVAC or built environment applications\n\nDeep working knowledge of numerical methods underlying CFD - turbulence modeling, mesh sensitivity, boundary conditions, solver selection\n\nHands-on experience with CFD platforms. Familiarity with SimScale and/or Flovent is a plus.\n\nStrong understanding of HVAC fundamentals - not just the software, but the underlying physics of heat transfer, airflow, and psychrometrics\n\nExperience with at least some of: hospital/healthcare design, smoke control, contaminant transport, outdoor airflow analysis, or thermal comfort assessment\n\nWho You Are\nGenuinely curious. You find the problem interesting, not just the deliverable. You push past the first answer when something doesn't look right.\n\nA clear communicator. You can explain what a vortex is doing to an HVAC engineer who hasn't opened a fluid mechanics textbook since grad school - and you enjoy doing it.\n\nRigorous but practical. You understand the limits of your models and are honest about them. You know when a simpler approach is the right approach.\n\nCollaborative. You see yourself as a resource to the engineers around you, not just a specialist in a silo. You're comfortable not always being the one who owns the project.\n\nProfessionally engaged. You follow developments in simulation tools, building science, and HVAC. You have opinions about them.\n\nWhy Work at JB&B?\nLegacy + Innovation: Our company blends a rich history with forward-thinking design, including smart building systems and deep carbon reduction strategies.\nCollaborative Culture: With over 400 professionals, our company fosters mentorship, teamwork, and continuous learning\nGlobal Impact: Now part of Trinity, our company offers opportunities to work on transformative projects across commercial, healthcare, aviation, life sciences, and data center sectors\nMultiple office locations: New York, Boston and Philadelphia\n What We OfferHybrid workplace offering the flexibility to work both from home and the office\nComprehensive benefits package including 401k employer match and stock options\nPaid time off (PTO), volunteer program and employee resource groups\nTraining and professional development courses through JB&B University\nEstimated compensation range: $110,000 - $140,000 annual salary\nJaros, Baum & Bolles is an equal-opportunity employer.
