Do you want to be a part of a growing M&E team? Can you collaborate with colleagues across UK and International projects? Are you experienced in Mechanical Infrastructure Design? Then, this could be the next adventure in your career.
Create Solutions that will enable a better tomorrow
To further our mechanical capability on Infrastructure projects, we are looking for a Senior Mechanical Engineer with a Water Utilities background to join us. Your primary task will be to deliver engineering work related to the design of elements including water supply and wastewater infrastructure and non-infrastructure equipment. This includes pressurised mains, pumping stations, treatment works apparatus and other relevant equipment. Your role will be focused on the design environment, which, while based in the UK, will involve interacting day-to-day with colleagues across our global hubs. There may also be opportunities to broaden your contribution to other areas within the MEP discipline as well as client-side or site-based roles in a variety of major infrastructure settings.
Your key responsibilities will be:
* Contributing towards the design of projects for a wide range of clients
* Planning design work and deliverables together with wider MEP team
* Development and technical assurance of design including use of relevant software
* Ensuring compliance with both local and international standards
* Coordination of multi-disciplinary aspects of projects
* Mentoring junior team members in design
* Contributing to the building of relationships with clients and other stakeholders
Your skills. Our team. Together we design the future. The first step to success in this role is that you are eager to collaborate with the people around you, whether they are colleagues, partners, or customers. Developing ties with others is something you do by acting respectfully and delivering on your promises. And you never get set in your ways but keep exploring new insights and ways to improve.
On top of that, you'll have:
* A degree in mechanical engineering or similar
* Achieved Chartered Engineer status (or equivalent)
* Relevant experience within mechanical systems design
* A solid mechanical understanding of water-based systems such as pressurised water supply mains, pumping stations and treatment works apparatus
* Experience with hydraulic modelling of pipe networks, steady state and transient analysis calculations
* Knowledge on pipe support and stress calculations
* Exposure to other mechanical equipment such as lifting equipment, actuated hydraulic gates and building services would be an advantage
* Experience with 3D and BIM design
* Knowledge of relevant Water Industry Specifications (WIMES)
* Experience of applying CDM2015 regulations to design tasks
* Experience of design and build projects would be beneficial which may include designer's representation on site
