• A tertiary engineering qualification with 4–7 years in engineering.
• Experience in RCA, FMEA or RCM methodologies.
• Ability to interpret fault/failure data to identify trends.
• Ability to collaborate across mechanical, electrical, controls and software disciplines.
• Excellent written and verbal communication skills.
• Able and willing to travel interstate and internationally.

Responsibilities

• Own Post Change Validation (PCV) within the Product Change Order (PCO) process and report outcomes to stakeholders.
• Lead fleet-wide fault and failure data analysis to identify recurring failure modes and quantify impact on unit availability.
• Facilitate root cause investigations for safety and reliability incidents with SME input from multiple domains.
• Develop and maintain a failure mode taxonomy (FMEA-based) across PhotonAssay subsystems.
• Support reliability-related obsolescence decisions by quantifying fleet failure risk for spares planning.
• Provide regular reports on fault trends, investigations and PCV results to leadership.
• Engage with partners on reliability investigations and improvements.
• Collaborate with Product Improvement to prioritise design corrective actions from fleet data.
• Define reliability questions and success criteria with Maintenance Data Scientist for actionable maintenance actions.
• Review and improve Maintenance procedures and strategies with Maintenance specialists.
• Contribute reliability input at new product design gates (concept to pre-launch) including targets and DFMEA involvement.
• Liaise with Deployment and Maintenance to capture failure data accurately.
• Engage with suppliers on failure investigations and design improvements.
• Refine the failure mode taxonomy and data capture methods across the fleet.

Job description

The Chrysos commitment and mission:

Here at Chrysos we combine science and software to create technology solutions that are changing the global mining industry; both from a productivity and environmental impact perspective.

Just like atoms and machines, we believe that everyone is different and how individuals come together is what makes us successful. Headquartered in Adelaide and with team members based in Australia, New Zealand, Europe, Africa, Canada, Chile and North America, Chrysos Corporation’s diverse team of scientists, engineers and industry specialists are coming together to build technologies to provide rapid, accurate and safe ore analysis for the global mining industry.

The company’s flagship technology, PhotonAssay™, steps around centuries-old chemistry-based assay methods to deliver true ‘atom-counting’ analysis for the measurement of gold and other high-value metals. With successful global installations, Chrysos is taking PhotonAssay™ to customers around the world – Chrysos could take you to places that you might not have even imagined yet. There’s opportunity around every corner and the support to help you achieve your goals.

About the role:

The Reliability Engineer, based in Adelaide, will be a core member of the Product Improvement team, responsible for building and leading Chrysos’s reliability engineering capability – turning fleet fault and failure data into prioritised design and process improvements that increase equipment reliability and reduce unplanned downtime across the global PhotonAssay™ fleet.

What you will do:

• Own Post Change Validation (PCV) within the Product Change Order (PCO) process: for each PCO, define success criteria and verification methodology up front, execute or coordinate the check at the appropriate interval, and report outcomes – including negative results – back to the design/process owner and leadership.
• Lead fleet-wide fault and failure data analysis, working closely with the Maintenance Data Scientist, to identify recurring failure modes and quantify their impact on unit availability.
• Facilitate root cause investigations for safety and reliability incidents, coordinating input from electrical, controls, mechanical, physics, and software subject matter experts.
• Develop and maintain a failure mode taxonomy (FMEA-based) across priority PhotonAssay™ subsystems, working with Product Improvement, Product Development and Maintenance teams to capture root cause at the point of failure.
• Support Product Improvement, Supply Chain and Maintenance on reliability-critical component obsolescence by quantifying fleet failure risk to inform LTB quantities and retrofit priority for existing units, balancing spares holding cost against downtime risk.
• Provide regular reports to the Product Optimisation Manager and Technical Leads on fault trends, investigation outcomes and PCV results.
• Act as a key point of technical liaison with Nuctech and other engineering partners on reliability-related investigations.
• Display role model behaviour to Chrysos’ culture of safety and zero-harm.
• Collaborate with Product Improvement engineers to prioritise and scope design corrective actions arising from fleet fault data.
• Work closely with the Maintenance Data Scientist to define reliability questions and success criteria, and to translate statistical/predictive outputs into practical maintenance and design actions.
• Work with Maintenance specialists to review Maintenance procedures and strategies and assist with making necessary improvements.
• Provide reliability input at new product design gates (concept, detail design, pre-launch), including reliability targets, DFMEA participation, incorporation of field failure history, and identifying diagnostic data/instrumentation needs.
• Liaise with Deployment and Maintenance teams to support accurate root-cause data capture at the point of failure.
• Engage closely with Nuctech and other suppliers on failure investigations and design reliability improvements.
• Build and continuously refine the failure mode taxonomy and root-cause data capture methodology across the fleet.
• Stay informed of industry best practice in reliability engineering (RCM, FMEA, RCA) and incorporate relevant methodologies into Chrysos processes.

Who you are:

Essential

• A tertiary qualification in engineering (mechanical, electrical, mechatronic or related discipline).
• 4–7 years’ experience in an engineering role, including demonstrated experience in RCA, FMEA or RCM methodologies.
• Experience interpreting fault, failure or maintenance data to identify trends and prioritise action (formal data science training not required, but must be data literate).
• Ability to work across mechanical, electrical, controls and software disciplines at a level sufficient to frame problems, and engage subject matter experts.
• Excellent written and verbal communication skills, including the preparation of clear technical reports and recommendations for leadership.
• Able and willing to travel both interstate and internationally (subject to Australian Government travel restrictions).

Desirable

• Formal certification or training to reliability engineering methodologies (RCM, FMEA, RCA, or similar).
• Experience with automation systems (PLC/controls, drives, sensors, interlocks) sufficient to understand and interrogate fleet failure modes in these systems.
• Experience working closely with data scientists or data analysts on fault/failure data.
• Experience with CMMS systems and fault/maintenance data structures.
• Experience working with global teams and cultures, including OEM and manufacturing partners

Who we are (Our values):

• Safety is a Non-Negotiable - Safety isn’t just a value — it’s our way of life. It’s about creating a culture where physical and psychological safety are top priorities. We speak up, challenge assumptions, and hold ourselves accountable to protect one another.
