As we power back into production, this is an opportunity to be part of recharging a critical operation at the centre of the global battery supply chain. With open pit mining recommencing and underground development at the BP33 deposit about to begin, we are seeking an experienced Senior Mining Engineer to play a key role in establishing and supporting the underground mining function through development, production and long-term ramp-up. This is a rare opportunity to join an underground operation at the very beginning, helping shape systems, processes, and standards from early development through to full-scale production, while taking ownership of a long-term role offering significant autonomy, variety, and influence within an exciting underground lithium operation. While our long-term preference is for the successful candidate to relocate to Darwin and become part of the Finniss team, we understand relocation takes time. An initial FIFO arrangement can be considered while suitable accommodation is secured, with relocation assistance provided.

You will ideally bring: Experience within underground hard rock mining operations Demonstrated experience in underground mine design and production support Strong understanding of underground development, stoping, and production processes Experience with short-term planning, scheduling, and operational integration Exposure to ventilation planning and underground operational requirements Experience in drill and blast design and optimisation Strong reconciliation and reporting capabilities Ability to work independently and confidently within a small technical team Strong stakeholder engagement and contractor management skills Experience using Deswik and/or similar underground mine planning software A proactive and hands-on approach with a strong sense of ownership and accountability Preference will be given to candidates with exposure to underground backfill systems, including cemented rock fill (CRF) and paste fill design and operational integration. About Core Lithium At Core Lithium, you won't be stepping into a mature underground operation where systems, processes, and ways of working are already established. Instead, you'll have the opportunity to be part of building the BP33 underground mine from the ground up, contributing to the development of the standards, systems, and technical frameworks that will underpin a safe, productive, and successful operation for years to come. Working within a lean and highly collaborative team, you'll enjoy broad exposure across mine planning, underground development, production, technical services, contractors, and operational leadership. Your ideas and expertise will be valued, and your contribution will have a genuine impact on how the underground operation evolves.
