Mechanical Engineer - Battery Recycling

• Owner-side role managing external EPC/EPCM contractors on unique projects
• Hands-on technical work combined with strategic engineering leadership
• Work across cutting-edge battery recycling and critical minerals tech

Join our dynamic team as a Mechanical Engineer – Battery Recycling, where you'll contribute to a multitude of mechanical engineering outcomes across demonstration and commercial-scale process plants in the critical minerals sector. In this owner-side engineering role, you'll provide mechanical engineering guidance across process plant development, modifications and projects, whilst managing and interrogating the work of external EPC/EPCM and specialist engineering contractors to deliver practical, safe and maintainable facilities. You'll develop and review mechanical equipment specifications, layouts, P&IDs and design documentation, undertaking smaller design tasks and engineering calculations yourself while leveraging external partners for larger packages. Your technical credibility will be essential as you challenge designs, review deliverables and ensure engineering solutions meet project requirements across minerals processing and hydrometallurgy environments. Working closely with operations, maintenance and multidisciplinary teams, you'll support projects from concept through commissioning, providing hands-on technical input during fabrication, construction and troubleshooting activities. This role demands strong contractor and stakeholder management skills, combined with practical experience in mechanical equipment design, process plant environments and the ability to translate operational challenges into effective engineering solutions. You'll be the bridge between engineering, project delivery and operations, ensuring mechanical outcomes are fit for purpose in a technically unique battery recycling facility.
