We’re looking for a design-focused Senior Mechanical Engineer with resources-sector experience.

Iridium Project Delivery is a growing Perth-based engineering and project delivery consultancy supporting clients across the Australian resources sector. As our project portfolio continues to grow, we're looking for an experienced Senior Mechanical Engineer to join our team and take a key role in the design and delivery of materials handling and mechanical infrastructure projects. This is a hands-on, design-focused engineering role suited to someone who enjoys developing practical engineering solutions, working closely with designers and seeing projects progress from concept and studies through detailed design and into construction.

Why Join Iridium?

You'll join a growing engineering consultancy where company leaders and senior engineers remain closely involved in the technical work and have a direct influence on how projects are delivered.

We offer

- Exposure to projects from concept and studies through detailed design and execution
- A strong focus on practical, high-quality engineering and design
- Significant involvement in sustaining capital works including bulk materials handling and wet processing
- The opportunity to lead mechanical design packages and work directly with clients
- A Perth-based role supporting projects across Western Australia's resources sector
- Variety across sustaining capital, brownfields and project development work
- Flexible working from home arrangements

About the Role Working within Iridium's engineering and project delivery team, you'll be responsible for mechanical engineering and design across materials handling and associated resources infrastructure.

The role will have a strong technical and design focus, you'll work closely with our mechanical designers, other engineering disciplines, clients, vendors and contractors to develop solutions that are technically sound, constructable,



maintainable and appropriate for the operating environment.

Day-to-day, you'll:

- Develop mechanical designs from concept through to detailed design
- Undertake engineering of bulk materials handling systems and processing equipment
- Develop and review designs for conveyors, transfer chutes, feeders, bins, hoppers, stockpile systems and associated mechanical equipment
- Prepare mechanical calculations, equipment sizing and technical assessments
- Develop equipment specifications, datasheets, scopes of work and technical documentation
- Prepare and review mechanical equipment layouts and 3D models in conjunction with designers
- Lead mechanical design packages and coordinate interfaces with structural, civil, electrical and process disciplines
- Review vendor documentation, drawings and technical submissions
- Undertake technical bid evaluations and support equipment selection
- Participate in design reviews, constructability reviews, HAZOPS and project risk reviews
- Undertake brownfields investigations, site inspections and development of practical modification solutions
- Liaise directly with clients, vendors, fabricators and contractors
- Mentor engineers and designers and contribute to the development of Iridium's engineering standards and systems

About You We're looking for an experienced mechanical engineer with a robust design background and a practical understanding of how resources projects are engineered, constructed, operated and maintained.

You'll bring

- Bachelor's degree in Mechanical Engineering or equivalent




- 5+ years' relevant mechanical engineering experience, with senior-level capability
- Strong mechanical design and engineering fundamentals
- Experience in mining, minerals processing, bulk materials handling or resources infrastructure
- Experience with materials handling equipment such as conveyors, feeders, chutes, bins, hoppers and stockpile/reclaim systems
- Ability to develop calculations, specifications, datasheets and engineering deliverables with limited supervision
- Experience working effectively with mechanical designers and 3D design models
- Working knowledge of relevant Australian Standards and resources-sector engineering practices
- Practical understanding of fabrication, construction, maintainability and brownfields design
- Strong technical problem-solving and communication skills
- Ability to manage mechanical engineering packages and take ownership of technical outcomes
- Permanent Australian work rights

Experience with ports, iron ore, lithium, mineral sands, crushing and screening, shiploading or other bulk commodity infrastructure will be highly regarded. Experience with mechanical design software, materials handling calculations and multidisciplinary detailed design projects will also be advantageous.

Membership or eligibility for membership with Engineers Australia is desirable.

The Opportunity

This role suits an engineer who wants to remain technically involved in engineering and design, rather than moving into a predominantly management-based role.

You'll have the opportunity to take ownership of mechanical packages, work directly with experienced designers and clients, and play a significant part in building the engineering capability of a growing Perth consultancy.

If you're a Senior Mechanical Engineer with strong materials handling and design experience who wants to remain close to the technical work, we'd like to hear from you.
