Job Description
Mott MacDonald are world leaders in the design, development and delivery of underground transportation schemes both in the UK and overseas. This includes metros systems, rail and road tunnels.

We are currently looking for a Senior CFD Engineer from the GDS location in India to work with our CFD team based in Croydon/London.

We conduct CFD studies for a range of applications such as fire and smoke spread in tunnels and stations, ventilation and heating of facilities, wind engineering, pedestrian comfort analysis and hydraulic modelling of water utility installations. We also provide fluid dynamics and heat transfer advice and support to other teams within the business.

You will be required to act as a senior CFD modeller on projects, leading CFD tasks and undertaking simulations, involving fluid mechanics and multi-physics engineering analyses, together with supportive verification and validation activities. You may also be asked to support less experienced team members in the delivery of project tasks.

You will be participating in project meetings involving internal and external clients/stakeholders, supporting requirements of different engineering projects. As part of your responsibilities, you will be expected to present work and lead discussions on tasks and aspects of CFD projects, for which you lead.

It is expected that you will manage tasks effectively and efficiently, ensuring that all work is delivered to high quality and best practice standards, together with budgets and deliverable time scales. Frequently, projects will require close liaising with technical teams in other areas such as tunnel ventilation, fire engineering, mechanical engineering design, building design, water and wind engineering, which are often widespread geographically. You would be expected to provide high quality reporting of the work you lead in terms of technical notes and full study engineering reports, providing project output and deliverables matching client's requirements.

You will be encouraged to develop your advanced consulting skills with a view to undertaking tasks of increasing complexity in terms of technical solutions and task coordination and management of resources. In undertaking your duties there will be continuous interfacing and support provided from your colleagues in the CFD team and wider teams which you will be a part of.
