Unlike traditional service providers, we don’t just identify problems and walk away. We create integrated, compounding value for our clients by taking ownership of the building lifecycle—from strategic advice and optimisation through to delivery and ongoing performance.

Across energy and sustainability, safety and compliance, building optimisation, predictive maintenance, and integrated technology solutions, we combine deep technical expertise with operational excellence to deliver smarter, more efficient, and more sustainable buildings.

As VerdeOS continues its rapid growth across Australia, we’re investing heavily in both our people and our technology. This creates exciting opportunities for ambitious engineers who want to make a genuine impact, deepen their technical expertise, and grow their careers alongside a fast-expanding company.

• Report operational insights and clear recommendations to drive better client decision-making.
• Ensure client reports and deliverables are completed on time, to scope, and to a high standard.

Cultivate Strong Relationships

• Act as the primary client-facing engineer for assigned projects.
• Collaborate with key stakeholders to deliver and expand building optimisation services.
• Translate technical findings into meaningful business outcomes for clients.

Promote Sustainability

• Develop and implement strategies to reduce energy and water consumption, carbon emissions, and overall environmental impact.
• Help clients improve health, comfort, and safety for building occupants.
• Develop and refine algorithms and analytics tools to optimise performance and stay at the forefront of sustainability and building technology.
• Contribute operational insight to the ongoing development of VerdeOS technology platforms and software products.
• Identify opportunities to enhance service delivery through technology, automation, and analytics.
• Support knowledge sharing and documented procedures across the team.

About You
