About Us

At HDR, we specialise in engineering, architecture, environmental and construction services. Our global team of more than 15,000 employees is united by our values and strengthened by our employee-owned culture. We collaborate across disciplines, leverage global expertise, and empower our people to create solutions that make a lasting impact.

Design the Critical Environments Powering a Digital Future

At HDR, we're doing something different.

As an employee-owned business, our people don't just contribute to projects, they take ownership of them. You'll work alongside some of the industry's most respected technical specialists, delivering complex and critical infrastructure that supports the way businesses, communities and economies connect and operate.

Engineering What's Next

HDR delivers some of Australia's most complex and high-performing facilities, including hyperscale data centres, critical infrastructure and mission-critical environments.

These projects demand technical excellence, innovation and close collaboration across disciplines. As part of our National Building Engineering Services team, you'll play a key role in leading the development of mechanical engineering solutions that are efficient, resilient and built for the future.

The Opportunity

We're growing our Building Engineering Services team in Melbourne and Sydney and are looking for a Senior Mechanical Engineer to support the delivery of technically challenging projects across our expanding Data Centre, Mission Critical and Building Engineering portfolio.

This opportunity is ideally suited to an experienced consulting engineer who enjoys taking ownership of design delivery, solving complex technical challenges and contributing to high-quality engineering outcomes across the full project lifecycle.

Working closely with our national mechanical team, you'll play a leading role in project delivery from concept through to construction, developing practical and innovative HVAC and building services solutions within a multidisciplinary design environment. You'll operate with a high degree of autonomy while supporting the growth and technical capability of the broader team.

In This Role You Will

Lead the delivery of mechanical design packages from concept through to construction delivery
Perform complex HVAC engineering calculations, system selection and design development
Prepare and review coordinated engineering documentation, specifications and technical reports
Take ownership of the delivery of compliant, high-quality mechanical building services solutions
Coordinate effectively across disciplines to resolve design interfaces, risks and technical challenges
Collaborate closely with architects, engineers, clients and specialist consultants across multidisciplinary projects
Provide technical guidance and mentoring to developing engineers and designers
Participate in and contribute to technical reviews, design quality processes and best-practice initiatives
Support site inspections, contractor queries and construction phase services
Contribute to project planning, resource coordination and successful project delivery outcomes
Support continuous improvement and technical excellence across the national mechanical team

What We're Looking For

Degree-qualified Mechanical Engineer
Typically 6-12 years' experience in a consulting engineering environment
Demonstrated experience delivering mechanical building services design projects with minimal supervision
Strong HVAC design capability and advanced technical problem-solving skills
Experience preparing and reviewing engineering reports, specifications and technical documentation
Strong understanding of Australian codes, standards and regulatory requirements, including NCC and AS1668
Proven ability to coordinate across disciplines and manage design interfaces
Strong communication, stakeholder management and collaboration skills
Proactive approach with a commitment to technical excellence and quality outcomes
Interest in developing broader project delivery, commercial awareness and leadership capability

Highly Regarded

Data Centre or Mission Critical project experience
Experience undertaking HVAC heat load calculations and system sizing, ideally using Camel software
Experience with pipe sizing and ductwork design for HVAC systems
Experience with Revit, Navisworks, ACC or other design coordination platforms
Exposure to health, defence, education, industrial, commercial, sports and aquatic or mixed-use projects
Chartered Professional Engineer (CPEng) status

Why Join HDR?

Employee ownership model – share in the success you help create
Data centre and TMT exposure – work on critical infrastructure shaping digital economies
Collaborative culture – learn from experienced leaders and technical specialists
Technical excellence – contribute to innovative and complex engineering solutions
Real impact – deliver projects that shape how people connect, grow and thrive
Career growth – develop toward technical leadership, project leadership or discipline leadership pathways

Why Our Roles Are Different

This is more than just another role.

You'll be joining a team that is:

Actively growing across NSW, VIC & QLD
Backed by a strong national and global business
Delivering complex, high-profile projects
Investing in technical excellence and innovation
Offering a genuine opportunity to grow your technical capability, leadership skills and career

At HDR, you're not just part of the team — you're part of the business. #LI-CG3
