About the Role
Tronox is seeking a technically capable and delivery-focused Senior Process Engineer to support process engineering activities across both the Definitive Feasibility Study (DFS) and Execution phases of a major Rare Earths project in Western Australia.
We're looking for Process Engineers who are ready to take the next step in their career and grow into a Senior position. If you're eager to develop your skills and take on more complex, high‑impact work on an exciting new project, we'd love to hear from you.
This role is responsible for developing and reviewing process design deliverables, supporting interdisciplinary coordination, and contributing to the safe, efficient, and compliant design of process systems. You will work closely with a Process Engineer, Senior Process Engineer, Engineering Manager, and the Engineering Service Provider (ESP) to ensure that process engineering outputs are technically robust and aligned with project objectives.
This position plays a key role in ensuring process systems are ready for detailed design, construction, and commissioning.
Initially offered as a 12-month fixed-term contract for the DFS phase, this role is designed to become permanentonce the project achieves FID and moves into Execution.
This role will initially be based at our Kwinana Pigment Plant, located approximately 35 minutes south of Perth. Once setup activities are complete, the position will transition to our Fremantle office expected to happen end of Q1 2026.
