Office Administrator

About Us

At Sinclair Renewable Energy, we're not just another solar company – we're a passionate, community-focused team helping households and businesses take control of their energy future.

We're tradespeople, not salespeople – committed to delivering high-quality solar, battery, EV charging, and off-grid solutions with honesty and technical excellence.

• A bright and friendly personality with strong communication skills
• Excellent organisation and time management
• Confidence to work independently and as part of a team
• A problem-solving mindset with good judgement and common sense
• Proven ability to manage competing priorities under pressure
• Competency in Microsoft Office (Excel, Word, Outlook)
• Familiarity with cloud-based job management systems
• A proactive mindset and eye for continuous improvement

Why Join Us?

At Sinclair Renewable Energy, you're not just joining a business – you're joining a mission. We care about doing things properly, treating people with respect, and building a cleaner future one system at a time.

What we offer:

• Purposeful work in the renewable energy industry
• Supportive team culture with great people
• Flexible hours to suit your lifestyle (your child's school hours or part-time negotiable)
• Opportunity to grow with the business
• Office based in the Heatherbrae with free on-site parking
