Job Description

About Costain and your project.

This is a unique opportunity to join an agile technical team of process engineers working on the front line with operational teams to develop innovative practical and digital process solutions. . This is a home based opportunity with the requirement to travel to multiple sites on a weekly basis.


Costain helps to improve people’s lives with integrated, leading edge, smart infrastructure solutions across the UK’s energy, water, transportation and defence markets. We help our clients improve their business performance by increasing capacity, improving customer service, safeguarding security, enhancing resilience, decarbonising and delivering increased efficiency.  Our vision is to be the UK’s leading smart infrastructure solutions company.  We will achieve this by focusing on blue chip clients whose major spending plans are underpinned by strategic national needs, regulatory commitments, legislation or essential performance requirements. We offer our clients leading edge solutions that are digitally optimised through the following five services which cover the whole lifecycle of their assets:  future-shaping strategic consultancy; consultancy and advisory; digital technology solutions; asset optimisation and complex programme delivery.  Our culture and values underpin everything we do.


Due to recent project awards and an exciting pipeline of further work being tendered, we are looking to grow our Asset Optimisation Team which provides wastewater process engineering consultancy to support our clients across the UK to get the very best from their assets and programmes. This is a unique opportunity to join an agile technical team of process engineers working on the front line with operational teams to develop innovative practical and digital process solutions. Our team delivers optimisation studies at feasibility, concept, optioneering and preliminary design stages to mitigate risk, return sites to compliance, or enable low or no build solutions to be provided for new permit drivers.

Initial roles will be for South England but we are also interested in hearing from candidates to support future work in North England.
