Multiworks + You

Are you looking to make a real difference at a civil and utility infrastructure company recognised as a Great Place to Work? At Multiworks, we build and maintain the essential infrastructure that keeps communities running, across water, power, rail, transport, defence and private developments. Behind every project is a close-knit team that works hard, shares a laugh and backs each other. We welcome fresh ideas and outside-the-box thinking, and every person here has the chance to shape how we work and who we become.

About The Role

At Multiworks, we believe that great people are the cornerstone of a great business, and how we succeed in the industry. We are on the hunt for an Office Manager / People & Culture Administrator to join our People & Culture team.

This is a full-time, permanent position based in our Brooklyn office.

Reporting to our Chief People Officer, a supportive leader who backs her team and champions new ideas, your number one goal will be to bring warmth, fun and energy to our office, giving our people a great experience from the moment they walk through the doors.

Job Summary

In this role, you’ll be the heart of our Brooklyn office and the person who makes Multiworks a great place to work. You’ll create a welcoming, energised workplace, keep the office running smoothly and bring our people together through events, from end of year celebrations to site BBQs and family days. You’ll own the employee journey from signed offer to final day, which covers onboarding, offboarding, HR administration, IT assets and PPE, so every team member feels supported and set up for success. As the go-to person for general HR questions, you’ll also support recruitment and help drive our Great Place to Work initiatives.

Essential

• An engaging, positive and energetic personality who builds relationships easily.
• A love for (or keen interest in) construction and the people who build the infrastructure we all rely on.
• A self-starter who takes ownership and acts without waiting to be asked.
• 3+ years in an office management, HR administration or HR coordinator role, ideally a blend of both.
• Experience in seamlessly coordinating office events end-to-end.
• End-to-end onboarding and offboarding administration experience, including contracts and employee records.
• Confident with Employment Hero (or a similar HRIS) and advanced Microsoft 365 skills.
• Highly organised, able to juggle competing priorities with minimal supervision.
• Clear, warm communication with people at every level, from site crews to executives.
• Full Australian working rights, a current driver licence, and the flexibility to occasionally work outside standard hours to run events.

Desirable

• Certificate IV in HR (or working towards an HR qualification).
• Familiarity with verifying tickets and licences (e.g. White Card) and VEVO checks.
• Experience supporting recruitment and pre‑employment checks.
• Canva or similar design skills.
