About the Role
Shape the future of our cities and environments by joining AtkinsRéalis as a Principal Waste Water Process Engineer within the Design & Advanced Technology (D&AT) Practice. You will be part of a talented, multi-disciplinary team delivering cutting-edge, iconic projects for major UK water clients including Thames Water, Anglian Water, South East Water, Southern Water, and other regional authorities. This role offers the opportunity to work on transformational programmes for critical UK infrastructure and landmark engineering projects both domestically and internationally.

Key responsibilities include coordinating or managing a team of Process Engineers to deliver technical design work on projects ranging from small to complex multi-disciplinary schemes, following relevant national and project-specific design codes and standards. You will produce and review technical deliverables such as design reports, process calculations, and process control philosophies, working independently with minimal guidance. You will provide technical input into project design deliverables, manage time and budgets alongside project management, and collaborate with stakeholders at all levels.

Mentorship of junior colleagues and growing Process Engineering capabilities within the team are important aspects of the role. You will also provide technical support for bid proposals and work closely within multi-disciplinary teams both in the UK and overseas. Adherence to quality assurance standards and thorough review of your own and others’ work is essential.

AtkinsRéalis fosters a diverse and inclusive environment where collaboration and different perspectives are valued. We offer a supportive hybrid working culture, flexible holiday allowances, and a comprehensive range of benefits to help you balance a fulfilling personal and professional life.
