Lynas Rare Earths is an ethical and environmentally responsible producer of rare earth materials. Boasting a life of mine of 20+ years, our materials are used in many future-facing applications, including electronics, wind turbines and hybrid and electric vehicles.

Analyse process and environmental data to identify improvement opportunities
Assist with process optimisation projects, investigations, and trials
Ensure compliance with environmental and regulatory requirements
Work closely with Operations, Maintenance, and Environmental teams
Prepare technical reports, procedures, and performance metrics
Promote strong HSE and continuous improvement practices

What you will bring to the team:
Degree in Chemical, Metallurgical, Environmental Engineering, or related discipline
3–7 years’ experience in process engineering within mining or heavy industry
Experience with water treatment systems and process optimisation
Exposure to tailings systems and TSFs highly regarded
Strong analytical, communication, and problem-solving skills
Ability to work across remote FIFO operations
Commitment to safety, sustainability, and operational excellence

Candidates with the following desirable qualifications and experience will be highly regarded:

Design, commissioning, and optimisation of water treatment and tailings-related projects
Water treatment chemicals
Dangerous goods and process safety
Postgraduate qualifications
Membership with a relevant professional body
Command in water chemistry / simulation software (i.e. Visual Minteq, etc.).
