Computational Modeller

.

• Ongoing | Full Time | Band 5/6 (Linked) | + 15.4% super | Salary packaging available
• Band 5: $100,445 – $112,773 | Band 6: $119,641 – $134,236
• Lucas Heights, Sutherland Shire | Flexible work practices | Onsite childcare | Fitness Passport
• Free onsite parking | pool, soccer field & café | ANSTO bus service available
• Rare opportunity to pair advanced computational modelling with world-class experimental characterisation – and see your work underpin real safety and lifetime decisions

ANSTO’s Nuclear Materials Research and Technology Group is seeking a Computational Modeller to join our team at Lucas Heights. You will apply numerical modelling techniques – including finite element analysis, crystal plasticity and continuum-scale materials modelling – to analyse materials behaviour, component performance and engineering systems. Your work will directly support the safe and continued operation of ANSTO’s nuclear research facilities and contribute to our research and commercial programs for Australian and international partners.

What makes this role unusual is the loop between simulation and measurement. Modelling here is informed, calibrated and validated by experimental work you help design and carry out, using ANSTO’s landmark research infrastructure and materials characterisation capability. You will publish in the peer-reviewed literature, report to industry clients and regulators, and collaborate with leading international organisations.

This is a linked Band 5/6 position. Candidates will be appointed at the band that matches their experience. Progression from Band 5 to Band 6 is not automatic and follows a formal assessment against the requirements set out in the Position Description.

“I am looking for a curious and rigorous modeller who wants their simulations to matter – someone who is as comfortable interrogating an experimental dataset as they are building the model, and who wants to see their analysis underpin decisions about the safe operation of a nuclear facility. You will join a collaborative, internationally connected team, and we will back you to build a genuine research reputation of your own.”

• PhD in Mechanical Engineering, Materials Science, Nuclear Engineering or an equivalent relevant discipline
• Demonstrated knowledge of numerical modelling methods and computational tools for the analysis of engineering materials, components and systems
• Demonstrated ability to develop numerical and mathematical models for materials properties and component behaviour
• Demonstrated capacity to plan and carry out experimental work to inform, calibrate and validate numerical models
• Demonstrated ability to work independently and effectively, and to contribute and share knowledge within a research project team
• Excellent written and verbal communication skills, including a record of technical reporting and peer-reviewed publication

• Experience applying engineering codes and standards relevant to nuclear or other safety-critical applications (e.g. ASME, R6)
• Experience with verification and validation practices for numerical models supporting safety cases or regulatory submissions
• Experience independently scoping, managing and delivering commercial or research projects, and contributing to research funding and grant applications
• Experience mentoring or supervising junior researchers, students, secondees or visiting staff

Appointment at Band 6 will require a demonstrated track record against the additional criteria set out in the Position Description.
