Associate/Senior Associate

Step into a role where advanced simulation, parametric design, and environmental analysis directly shape high‑performance buildings and complex engineering projects. This is an opportunity to work at the forefront of digital design, using industry‑leading CFD and building performance tools to influence key design decisions from early concept through detailed development.

About the Role:

You will lead and support simulation and analysis workflows across a range of projects, delivering robust, data‑driven insight to design and engineering teams. Working in a hybrid environment, you will be responsible for setting up, running, and interpreting advanced CFD and building performance models, and translating results into clear, actionable recommendations. Your work will directly inform design optimisation, comfort and sustainability strategies, and compliance with performance targets.

Key Responsibilities:

Develop, set up, and run CFD simulations using ANSYS Fluent/CFX, OpenFOAM, and Star‑CCM+ for airflow, thermal, and related performance studies.
Build and manage building performance and energy models using Cadence DC, IES‑VE, and TAS to assess energy use, comfort, and environmental performance.
Create and maintain parametric geometry and analysis workflows in Rhino and Grasshopper, integrating Ladybug and Honeybee for climate‑based and daylight simulations.
Post‑process and interpret simulation outputs, preparing clear visualisations, reports, and presentations for technical and non‑technical stakeholders.
Collaborate closely with architects, engineers, and sustainability specialists to embed simulation insights into design decisions and project strategies.
Calibrate models with available data, perform sensitivity analyses, and ensure robustness and quality control of all simulations.
Support the development and refinement of internal tools, templates, and best practices for CFD and building performance analysis.
Contribute to project meetings and design reviews, explaining complex simulation findings in concise, practical terms.
Key Requirements:

Proven experience in CFD modelling with ANSYS Fluent and/or CFX, plus hands‑on use of OpenFOAM or Star‑CCM+ on real projects.
Strong background in building performance or environmental modelling using tools such as IES‑VE, TAS, and/or Cadence DC.
Proficiency in Rhino and Grasshopper for geometry handling and parametric workflows.
Practical experience using Ladybug and Honeybee for environmental, climate, and daylight analysis.
Ability to manage multiple simulation tasks concurrently, from problem definition through to delivery of recommendations.
Strong analytical, problem‑solving, and data interpretation skills, with attention to detail and model quality.
Clear written and verbal communication skills, with the ability to produce concise technical reports and presentations.
Experience working within multidisciplinary design or engineering teams.
Desirable Skills:

Experience automating workflows or scripting within Grasshopper or related environments.
Familiarity with additional simulation tools or plug‑ins for acoustics, comfort, or façade optimisation.
Exposure to sustainable design frameworks, building regulations, or green building rating systems.
Experience mentoring junior team members or leading smaller work packages.
Qualifications:

Degree in Mechanical Engineering, Building Services Engineering, Architectural Engineering, Computational Design, or a closely related discipline.
Postgraduate qualification in CFD, building physics, environmental design, or similar field preferred for Senior Associate level.
Professional membership or working towards membership of a relevant institution (e.g. CIBSE, IMechE, ASHRAE) is an advantage.
Evidence of continued professional development in simulation, building performance, or digital design tools.
