Executive Assistant to the Co-CEO

Our Mission:

At CIM, our product vision is to help teams run better buildings with ease, for a sustainable future. We focus on simplifying complex building data and technology, making it accessible and actionable for people who own and operate buildings, directly contributing to the fight against the climate crisis.

Our clients include real estate investment trusts, super funds, governments, major cultural institutions and property owners who operate offices, shopping centres, airports, and other commercial spaces. 

The built environment is one of the biggest contributors to climate change, accounting for almost 50% of global greenhouse gas emissions. Over half of these emissions are generated by operational activities, which our software Peak helps reduce by enabling property operations teams to work smarter and more collaboratively. 

Will you join us?

We’re looking for a high-performing, senior-level Executive Assistant and Office Manager to support one of our Co-CEOs and lead the day-to-day operations of our Sydney headquarters. This part-time role is ideal for someone who thrives in a high-trust, high-impact environment and wants to contribute meaningfully while maintaining flexibility.

You’ll work closely with a founder-CEO who has led multiple successful ventures — playing a central role in managing priorities, coordinating with key stakeholders, and ensuring the Sydney office runs smoothly and effectively.

This is not your average EA or office manager role — it's a senior, hybrid position that touches everything from client engagement to team culture to strategic execution.

What you’ll do: 

Executive Support & Strategic Coordination

• Provide high-level administrative and operational support to the Co-CEO, including calendar, travel, and inbox management
• Track key actions, priorities, and deliverables to ensure follow-through on high-impact initiatives
• Help manage and filter CEO requests, acting as a gatekeeper and trusted thought partner
• Support with light personal admin and logistics where appropriate
• Assist with the preparation of board packs, investor communications, and leadership updates
• Conduct research and prepare concise summaries to support informed decision-making

Client & Executive Engagement

• Proactively coordinate meetings with clients, prospects, partners, and board members
• Build strong relationships with senior stakeholders and executive assistants across our network
• Represent the CEO and the business with professionalism, warmth, and strategic awareness
• Identify opportunities to deepen relationships and unlock value from executive engagement

Office & Operations Leadership

• Own the day-to-day operations of the Sydney office — ensuring a well-run, stocked, and welcoming workplace
• Act as the first point of contact for visitors, vendors, and suppliers (IT, cleaning, maintenance, etc.)
• Monitor office equipment, kitchen supplies, and shared space upkeep
• Ensure WH&S compliance and act as the designated safety warden
• Triage incoming calls and direct messages to the right team members
• Communicate office policies and process updates clearly across the business

 Team Culture & Event Coordination

•  Plan and MC regular team sessions like weekly Wrap-Ups and quarterly Town Halls
•  Organise internal events, team activities, and office celebrations
•  Contribute creative energy to employee engagement and team-building initiatives
•  Be a visible culture leader — fostering collaboration, inclusion, and energy across the team

Who we are looking for

• Proven experience as a senior Executive Assistant, Office Manager, or similar leadership support role
• Comfortable balancing high-level strategic coordination with hands-on operational execution
• Highly organised, proactive, and emotionally intelligent
• Excellent communicator who builds trusted relationships with ease
• Comfortable working part-time while remaining tightly aligned to key priorities
• Passionate about sustainability, innovation, and supporting high-performing teams

We’re aware of research that indicates people identifying as women or from under-represented groups are far less likely to apply for roles if they don’t meet 100% of the requirements. At CIM, we’re interested in hiring passionate and curious people that are motivated to make a difference, so please still apply even if you don’t think you have the required experience in absolutely everything that we mention.
