OUR CULTURE

We are a joint venture between Tianqi Lithium Corporation and IGO Ltd. As pioneers in the Australian lithium industry, we've already achieved great things, including building the first battery-grade lithium hydroxide plant in Australia, paving the way for Australia to be a major player in the global transition to a clean energy future.

We’re looking for people who want to be a part of the industry of the future - people who work with purpose and urgency, take initiative, and rise to challenges. We're seeking individuals who empower others, embrace innovation, and want to work in an open and supportive environment, where teamwork and collaboration are valued.

At TLEA, you’ll be part of a team that is excited to be involved in a world-class project that benefits not only the Western Australian community but the world.

ABOUT THE POSITION

Are you passionate about making a real impact?

TLEA is welcoming applications for a full-time Senior Engineer Mechanical to join our team working at our Kwinana plant.

The successful applicant will be responsible for leading mechanical engineering activities on debottlenecking and brownfield modification projects (PMRs) at TLK’s lithium refinery operation plant. This role provides end-to-end technical input across the project lifecycle - from concept development through to construction support - ensuring all mechanical designs are safe, fit-for-purpose, and aligned with plant operability. The position requires strong coordination with internal stakeholders, consultants, and operations teams to deliver efficient, compliant, and constructible engineering solutions.

In addition to possessing our core values of distinction, pragmatism, honesty, tenacity and innovation, this position will suit an individual with extensive prior experience as a senior mechanical engineer, ideally within Brownfield Environments and Operations.

DUTIES & RESPONSIBILITIES
Lead mechanical design and technical assessments for assigned debottlenecking PMR projects, including piping, pressure equipment, rotating machinery, and mechanical packages.
Review and approve mechanical engineering deliverables such as datasheets, equipment specifications, layout drawings, tie-in details, and calculations.
Ensure all mechanical designs comply with relevant Australian Standards, TLK engineering practices, and operational requirements.
Coordinate with multi-discipline engineering teams (process, civil, structural, electrical, instrumentation) to ensure integrated design outcomes.
Support procurement through preparation of technical specifications, evaluation of vendor submissions, and review of vendor documentation.
Participate in HAZOPs, constructability reviews, and risk assessments to ensure safe and practical implementation of mechanical designs.
Provide engineering support during construction, commissioning, and handover phases.
Engage with operations and maintenance teams to ensure mechanical solutions are maintainable and aligned with site strategy.
WHAT YOU CAN BRING
Bachelor’s degree in mechanical engineering.
Minimum 10 years’ experience in mechanical engineering roles, including brownfield and project-based work in resource or chemical processing industries.
Sound understanding of Australian Standards (e.g., AS1210, AS4041, ASME) and engineering practices relevant to process plants.
Proven experience in pressure equipment, piping systems, rotating equipment, and layout design.
Experience reviewing 3D models, mechanical drawings, and design deliverables.
Strong communication and stakeholder engagement skills.
Safety-focused mindset with an ability to balance technical integrity and practical constructability.
WHAT WE OFFER
Contribute to a green and sustainable industry of the future.
Competitive salary with a performance-based discretionary bonus structure
Additional Superannuation
Award and recognition program
Long service leave option after 5 years (pro rata)
Supportive colleagues committed to your success and well-being
Inclusive and diverse work environment
LOCATION

TLEA proudly acknowledges and the Whadjuk and Gnaala Karla Boodja people of the Noongar Nation, as the traditional custodians of the Kwinana area, where we operate our plant.

HOW DO I APPLY?

To find out more about this unique opportunity, please submit your application by Thursday 17th September 2026 by clicking the 'Apply' button. All applications and discussions will be kept strictly confidential.

Applicants are advised that the shortlisting and interview process may commence before the closing date.
