Description
Business Development Manager, East Coast
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.
Why 5B?
At 5B, you will work on globally impactful technology with a team that values first principles thinking, speed, and practical innovation. We offer flexible working, progressive leave and parental policies, incremental extra leave based on tenure, and benefits that support life beyond work-all in a mission-driven, high-growth startup environment.

Mascot, NSW, Australia
2013
Employee count is not publicly disclosed, and revenue figures for 2023 or later are not reported.
What They Do
5B Australia Pty Ltd is a pioneering cleantech company that specializes in solar technology, particularly known for its innovative Maverick solar array system. The Maverick is a prefabricated, accordion-style ground-mount solar array that can generate between 50-70 kW per unit, designed specifically for utility-scale solar farms. This technology allows for rapid deployment, with full sites being operational in as little as 10-50 days, significantly reducing the need for onsite labor and cabling. The Maverick system is engineered to withstand extreme weather conditions, boasting a wind rating of 93 m/s, and is capable of integrating with various energy storage solutions and major solar module brands, enhancing its versatility in the renewable energy market (source: 5b.co).
Projects & Track Record
5B has an impressive portfolio of completed and ongoing projects that showcase its capabilities in the solar sector. Notable projects include a 1.5 MW deployment at a landfill in Albury, NSW, which powers a hydrocarbon plant and the surrounding town, and a 10 MWp installation at an off-grid nickel mine in Western Australia, completed in just 42 days. Additionally, the company has successfully deployed 17 MWp systems at both the Jundee Operations and Kathleen Valley lithium mine, demonstrating its efficiency and effectiveness in challenging environments. Ongoing projects include a significant 69 MWp installation in Jobos, Puerto Rico, and a 141 MWp project in Australia, further solidifying 5B's position as a leader in the solar industry (source: 5b.co).
Recent Developments
In recent years, 5B has made significant strides in expanding its operations and capabilities. In 2024, the company secured up to AU$46 million as the first recipient of Australia's Solar Sunshot Program, which will fund the expansion of its Adelaide factory to produce 200 MW of Maverick systems over three years. This funding is expected to reduce domestic production costs by 25% and facilitate a record order of over 100 MW. Furthermore, in October 2025, 5B signed a landmark module supply agreement with JA Solar for a project in Western Australia, marking a significant milestone in its growth trajectory (source: pv-tech.org).
Working There
5B offers a dynamic work environment with a focus on innovation and safety, attracting talent across various fields including manufacturing, engineering, and renewable energy. The company is actively hiring for roles in its Adelaide and Mascot facilities, with positions ranging from factory assembly to field deployment crews and engineering roles focused on renewable energy solutions. The culture at 5B emphasizes rapid deployment and a commitment to clean energy, driven by the founders' passion for engineering and sustainability. Although specific benefits are not publicly documented, the recent funding initiatives indicate a commitment to job creation and team growth (source: 5b.co).
