Marrickville New South Wales Australia PlasmaLeap Technologies Full time $80,000 - $120,000 per year

Company Description

PlasmaLeap Technologies is a globally recognised Australian clean-chemicals company reinventing how the world makes molecules. We're decarbonising heavy industry and eliminating input scarcity by putting clean, distributed chemical production in the hands of communities themselves. Our proprietary plasma reactors use renewable electricity, air and water to produce green fertilisers and fuels, creating a scalable, commercially viable pathway to net-zero that strengthens food security and bypasses fragile, fossil-fuel global supply chains entirely.

If you want to build deep tech that solves climate and food security in the same breath, and you want to do it at speed, with urgency, with purpose, and with people who are actually executing not just talking about it then you'll fit right in.

How you'll spend your time

Executive Support & Strategic Coordination

  • Manage the CEO's calendar, inbox, meetings and travel with discretion and proactivity
  • Prepare decks, briefs, agendas and materials for board, investor and partner engagement
  • Track priorities, relationships and action items across internal and external projects

People & Hiring

  • Coordinate recruitment activities, interviews and candidate communication
  • Manage onboarding and offboarding logistics to ensure fast, smooth ramp-up

  • Support culture initiatives including pulse surveys and internal updates

Events & External Engagement

  • Manage logistics for conferences, public-facing events and materials

Systems, Tools & Knowledge Management

  • Maintain internal systems, trackers and shared resources (Notion, SharePoint etc.)
  • Continuously improve workflows, processes and operating rhythm to help the team move faster

About You

  • Experience in an Executive Assistant, Office Manager, or similar operational support role. Preferably experience in rapid environments such as start-ups, venture-backed companies or similar high-velocity settings
  • Exceptionally organised with strong attention to detail and follow-through
  • Clear, concise communicator with strong written and verbal skills
  • Calm, positive and solutions-focused — especially under pressure and ambiguity
  • Highly trustworthy and comfortable handling sensitive information and relationships
  • Confident navigating Microsoft Office + modern SaaS tools (HubSpot, Notion etc.) and quick to pick up new systems
  • Disciplined operator who is focused on getting things done, not just talking about
