The Opportunity:

We are seeking a driven Business Development Manager (East Coast) who loves to use current relationships to sell, whose mission is to break open the market across QLD, NSW, VIC, ACT, and SA. This role must be based in Sydney or Brisbane.

This isn't a role for a process bureaucrat. We are looking for a true sales hunter—someone who lives for the thrill of identifying opportunities quickly, bringing deals across the finish line, and banking the sales.

You’ll start fast by closing behind-the-meter (BTM) and smaller demonstrator solar projects (~5MWac) in early 2027 to get Mavericks on the ground. In parallel, you’ll leverage your deep industry networks to quickly ramp up and convert utility-scale solar farm projects (50MWac+) within your first year.

Key Responsibilities:

Drive Sales & Bank Deals

• Identify & Capture Opportunities: Proactively hunt down BTM solar project opportunities and rapidly qualify land‑constrained, speed‑to‑power, or high‑load industrial/data center sites where the 5B Maverick value proposition wins.


• Deliver Early Wins: Secure quick‑turnaround behind-the-meter and smaller demonstrator projects (~5MWac) to establish immediate market credibility and demonstration sites on the East Coast.


• Scale to Utility Size: Rapidly scale your focus to build, manage, and close a major project pipeline of large multi‑MW and 50MWac+ solar farms.


• Commercial Negotiation: Drive deals from first conversation straight through to signed, profitable contracts with a clear focus on commercial outcome over heavy administrative process.

Network & Strategy

• Relationship Building: Tap into your existing network of solar developers, project owners, EPCs, and industrial energy users who are eager to deploy market‑disrupting solar tech.


• Market Intelligence: Feed real‑time commercial insights back into our team to refine our East Coast commercial positioning and stay ahead of the competition.


• Cross‑Functional Collaboration: Partner with our internal engineering, technical, and finance teams to package up winning, razor‑sharp commercial proposals.

About You:

Location & Availability

• Must reside in Sydney or Brisbane (with capacity for East Coast travel to deal sites as required).

Qualifications

• Practical technical sales background.

Experience

• Demonstrated sales success in energy projects with a clear track record of identifying and closing deals quickly.


• Proven capability to scale sales conversations up to large MW‑scale solar farm developments.


• 5–10 years of energy project or equipment sales experience (e.g. solar PV, BESS, inverters, power systems, or EPC services) with a history of closing million-dollar-plus contracts.


• Established, active networks with solar developers, owner‑operators, and consultants across the East Coast.


• Deep understanding of solar projects and the dynamics of projects on the East Coast, with insights where 5B’s value proposition can win.

Skills & Attributes

• Hungry Sales Hunter: Proactive, outcome‑obsessed, and driven to bank sales. Focused on outcomes before process.


• Commercially sharp deal maker, who can structure competitive offers and close profitable sales.


• Fast Assessor: Ability to look at a site or project brief, spot the commercial opportunity immediately, and jump on it before anyone else. Ability to understand which developers might want to do things differently with a new technology.


• Startup/Scale-up Culture Fit: Thrives in a fast‑paced, lean environment where you roll up your sleeves, work with passionate teammates, hit targets, and celebrate wins together.


• Resilient & Energetic: Motivated by both financial wins and the broader mission of accelerating renewable tech deployment.
