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. This strategic merger expands JB&B's capabilities and offers employees: • Access to a broader portfolio of international projects and clients, • Enhanced career mobility across Trinity's global network, • Interdisciplinary collaboration with experts in sustainability, environmental science, and digital infrastructureAbout 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. Key Responsibilities: Modeling & Analysis Develop 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 Evaluate thermal comfort conditions for occupants — accounting for airflow patterns, surface temperatures, radiant effects from glazing, solar gain, and more Model outdoor airflow dynamics: exhaust re-entrainment, equipment air intake/discharge, wind effects at building openings Simulate particulate and contaminant dispersion — pathogens, smoke, odors — in occupied spaces including critical environments (ORs, isolation rooms, labs) Analyze thermal microclimate effects from heat rejection sources such as heat pumps, generators, and cooling towers Collaboration & Problem-Framing Partner 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 Help engineers and clients ask better questions; bring CFD insight to the table before problems become costly to fix Serve as an internal technical resource and thought partner for the broader engineering team Deliverables & Communication Produce clear, well-organized simulation results with actionable recommendations Develop presentation materials — visualizations, reports, executive summaries — that make complex fluid dynamics legible to non-specialists Contribute to proposals, technical papers, and thought leadership content that elevates JB&B's reputation in building performance simulation Minimum Qualifications: B.S. or M.S. in Mechanical Engineering, Aerospace Engineering, Civil/Environmental Engineering, or a closely related field.

Strong understanding of HVAC fundamentals — not just the software, but the underlying physics of heat transfer, airflow, and psychrometrics Experience with at least some of: hospital/healthcare design, smoke control, contaminant transport, outdoor airflow analysis, or thermal comfort assessment Who You Are Genuinely curious. You find the problem interesting, not just the deliverable. You push past the first answer when something doesn't look right. A 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. Rigorous but practical. You understand the limits of your models and are honest about them. You know when a simpler approach is the right approach. Collaborative. 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. Professionally engaged. You follow developments in simulation tools, building science, and HVAC. You have opinions about them.

Job DescriptionWhat We Do Gecko Robotics is helping the world’s most important organizations ensure the availability, reliability, and sustainability of critical infrastructure. Gecko's complete and connected solutions combine wall-climbing robots, industry-leading sensors, and an AI-powered data platform to provide customers with a unique window into the current and future health of their physical assets. This enables real-time decision making to increase the efficiency and safety of operations, promote mission readiness, and protect the environment and civilization from the effects of infrastructure failure. Role at a Glance Gecko Robotics is seeking an AI/ML Engineering Intern to join our Engineering team in New York for Summer 2027. This is a full-time, onsite internship, Monday through Friday. Gecko collects some of the richest inspection data in the world: ultrasonic and other non-destructive testing (NDT) measurements from wall-climbing robots, paired with the documents, drawings, and operational records that describe the assets they inspect. You will work on a defined project that turns that data into decisions, building models and the systems around them that run reliably on real customer data. This is an engineering internship, not an analytics one. We build the systems that analyze the data, not just the analysis. Due to government program requirements, candidates must be authorized to work in the United States. What you will do Own a scoped machine learning project from problem framing through evaluation and integration, under the guidance of experienced engineers. Build data pipelines in Python that clean, label, and structure NDT sensor data, documents, or operational records for model training and inference. Train, evaluate, and iterate on models, and design evaluations that reflect how the output will be used in the field. Integrate a model or LLM-based workflow into a service or tool that other engineers and Forward Deployment Engineers can use. Investigate failure modes on messy, real-world data, document what you find, and recommend what to fix next. Use version control, code review, testing, and experiment tracking to produce work others can reproduce and build on. Present your project, results, and recommended next steps at the end of the internship. Technologies We Use Python, PyTorch or similar ML frameworks, NumPy and pandas, SQL, LLM APIs and agent frameworks, Git, Linux, and cloud infrastructure (GCP). Depending on the project, you may also work with signal-processing tools for ultrasonic data, document-processing and information-extraction pipelines, or orchestration tools such as Airflow. The specific tools will depend on the assigned project. About You You are an engineer who happens to work in machine learning. You care whether a model works on real data, not just on a benchmark, and you are comfortable owning the code around the model: the pipeline, the evaluation, and the integration. You approach new problems methodically, communicate clearly about results and uncertainty, and are excited to be the first person to look at a problem. Required Skills Currently pursuing a bachelor’s, master’s, or doctoral degree in computer science, electrical engineering, applied mathematics, physics, or a related technical discipline, with an expected graduation date between December 2027 and May 2028. Ability to work onsite in New York, Monday through Friday, for the full Summer 2027 internship. Strong programming experience in Python, including writing well-structured, tested code beyond notebooks. Coursework or project experience in machine learning, including training and evaluating models on real datasets. Working understanding of linear algebra, probability, and statistics. Working familiarity with Git or similar version control systems. Strong written and verbal communication skills, including the ability to explain results, quantify uncertainty, and collaborate on ambiguous problems. Ability to independently close knowledge gaps, stay organized, and learn from feedback. Preferred Skills Graduate-level coursework or research in machine learning, signal processing, or computer vision. Experience taking a model beyond a notebook: building a pipeline, an API, or a tool around it. Experience with LLM APIs, retrieval, information extraction, or document understanding. Experience with time-series or sensor data, especially ultrasonic, acoustic, or other physical measurements. Exposure to cloud infrastructure, preferably GCP, and to containers such as Docker. Interest in industrial, defense, or infrastructure applications where reliability matters. Who We Are At Gecko, our people are our greatest investment. In addition to competitive compensation packages, we offer company equity, 401(k) matching, gender-neutral parental leave, full medical, dental, and vision insurance, mental health, ongoing professional development, family planning assistance, and flexible paid time off. Gecko values collaboration, innovation, and partnership, and we believe we do our best work when we're together in person. We’re an office-first culture but understand that sometimes you may need to work from home. Many people are in the office five days a week, others need a bit more flexibility. Ultimately, we care about the outcomes we achieve - and creating a culture of autonomy and trust that enables that impact. Gecko is committed to creating a culture of inclusion and belonging, and we are proud to be an equal opportunity employer. We believe it is our collective responsibility to uphold these values and encourage candidates from all backgrounds to join us in our mission to protect today’s infrastructure and give form to tomorrow’s. All qualified applicants will be treated with respect and receive equal consideration for employment without regard to race, color, creed, religion, sex, gender identity, sexual orientation, national origin, disability, uniform service, veteran status, age, or any other protected characteristic per federal, state, or local law.

The Role You will design and iterate on heat exchangers, translating OEM specifications into novel concepts and turning them into simulation-backed designs and validated hardware. This role rewards engineers who are excited by invention: developing new architectures, challenging defaults, and making principled trade-offs when reality disagrees with a model. You'll work closely with product leads and OEM manufacturing partners, using Phasic's AI-driven design process to explore the design space quickly and intelligently. In the first 6 to 12 months, success means creating new HX solutions (and improving existing ones) that hit aggressive thermal and pressure-drop targets and hold up in real-world testing and certification. What You'll Do • Translate OEM specifications into heat exchanger concepts and detailed geometries, then iterate quickly toward performance and manufacturability targets., • Use both 1D/first-principles models and high-fidelity 3D CFD simulation to make design decisions (not just generate reports) and communicate trade-offs clearly., • Leverage Phasic's AI-driven design process to explore the design space, generate candidates, and converge on novel solutions., • Design with additive manufacturing constraints in mind (powder removal, support strategy, distortion, post-processing), and partner closely with manufacturing to ensure concepts can become reliable hardware., • Work with OEM manufacturing partners and internal product leads to align on requirements, constraints, and the "definition of done" for each design., • Close the loop between simulation and physical testing by planning validation, interpreting results, and improving models/design rules when they diverge., • Build reusable tools and artifacts (simulation setups, parameterized studies, design guidelines, validation datasets) that increase the team's speed and quality over time. What You Bring Required • Masters or greater in Mechanical Engineering, Thermal Engineering, or a related field with a concentration in thermal-fluid sciences (waste heat recovery or similar backgrounds are a plus)., • 5+ years of hands-on experience designing heat exchangers, cold plates, or thermal management hardware; not just analyzing other people's designs, but creating and iterating on geometry and standing behind performance outcomes., • Experience building first-principles 1D heat-exchanger models (MATLAB, EES, or Python) to support early-stage thermal design and performance assessment., • Demonstrated proficiency in CFD and thermal simulation/optimization tools (STAR-CCM+, Ansys Fluent, COMSOL, OpenFOAM or equivalent); you should be able to set up conjugate heat transfer problems for single phase and two phase flow regimes and have excellent understanding of CFD solvers. Integrating optimization with CFD workflows is essential., • Working knowledge of at least one CAD environment (SolidWorks, Siemens NX, or similar) and comfort designing internal flow passages and complex 3D geometries. Proficiency in surface modelling is a plus., • Experience with physical thermal testing, including instrumenting experiments, collecting data, and using the results to validate or challenge simulation outputs. This should include basic instrument calibration and uncertainty/error analysis. Experience using test data to calibrate CFD models is essential., • Clear, direct communication; you can explain a thermal trade-off to a non-thermal engineer and hold your ground when the data supports it., • Ability to make progress in ambiguous environments by rapidly defining assumptions, proposing initial solutions, and iterating based on feedback or new data. Nice to Have • Experience with metal additive manufacturing (L-PBF, SLM, DED, or binder jetting), especially designing parts that account for AM-specific constraints., • Familiarity with data center liquid cooling systems, CDUs, or rack-level thermal architectures., • Experience with topology optimization or generative design tools applied to thermal problems., • Experience working with contract manufacturers and navigating the gap between design intent and as-built reality., • Background in a startup or small-team environment where you wore multiple hats and shipped hardware under time pressure. Why Phasic • Join as a single-digit hire at a seed-stage company and own real outcomes from day one., • Get meaningful early-stage equity and the chance to build value over years, not quarters., • Work on a hard, high-leverage problem at the intersection of physics, manufacturing, and AI infrastructure., • Be part of a team that values craft, speed with rigor, and straightforward feedback, and celebrates excellent execution. Compensation and Benefits The base salary range for this role is $175,000 - $225,000 USD, depending on experience and qualifications. Actual compensation will be determined based on a variety of factors including skills, experience, and location. In addition to base salary, this role includes meaningful early-stage equity.
