We are partnering with a high-growth B2B SaaS business to find the CRO who can help build their next chapter of global growth.

The business has built a mission-critical platform supporting heavy-industry sectors across their people, workflows and data. They’ve established a strong position in Australia, are growing at 60–70% YoY, and have a significant opportunity ahead across North America and global markets.

The foundations are there. The opportunity now is to take what’s working and build the team, structure and repeatable commercial motions required to scale globally.

This is a genuine player-coach CRO role. We’re looking for someone who can:

• Own the global revenue strategy, bringing greater discipline and predictability to pipeline, forecasting and performance.
• Build repeatable mid-market and enterprise sales motions, with experience across complex sales cycles and driving revenue growth.
• Lead and develop the commercial function across Sales, Customer Success, Marketing and Demand Generation.
• Build the structure and operating cadence required to scale successfully across multiple regions.
• Partner closely with the founders and leadership team to help shape the next stage of the business.

We’re looking for someone who has genuinely scaled a B2B SaaS or enterprise technology business before, ideally across vertical SaaS, industrial technology or complex enterprise software and knows what it takes to build a high-performing commercial function through significant growth.

The sweet spot is someone who has operated through the $20M+ ARR stage, owned a meaningful revenue number and can bring the commercial discipline required to turn an already successful sales motion into a predictable, global revenue engine.

Some Data Scientists love research.
Some prefer the safety of large corporate teams.
Some chase FAANG logos.

And then there are the ones who just want to do great work with real-world AI — wherever the challenge is.

If you're in that last group, read on.

We're hiring a Data Scientist for a PE-backed AI consultancy with a growing national footprint (currently sub-10 people, but scaling fast). This team thrives on tackling high-impact, technically complex problems — from GenAI tooling to agent-based AI systems and government-grade infrastructure.

This role is open only to Australian Citizens due to upcoming work with federal agencies — if you have experience in or exposure to government departments, that’s a plus (but not essential).

What you’ll be doing:

• Building and deploying ML models and GenAI systems

• Working hands-on with AI agents, LLM pipelines, and secure environments

• Seeing your work go to production, not just proof-of-concept

• Collaborating with senior DS mentors who bring deep R&D and commercial expertise

What you bring:

• 5+ years hands-on experience in Data Science

• Strong Python skills across modelling and data wrangling

• Experience working with LLMs or AI agents (bonus points)

• Models in production (not just notebooks)

• PhD preferred, but not required

• Bonus: any background working on government or regulated data projects

Location:

Melbourne preferred
Open to Sydney-based candidates for the right fit
Must be an Australian Citizen (due to project security requirements)

Want to work with smart people, ship real AI solutions, and get your hands dirty?

Build, deploy, and enjoy.

You'll be joining an organisation at the start of a major technology transformation, where security will play a critical role in shaping what's next. In this role, you'll become its first dedicated Security Engineer. Reporting directly to the CTO, you'll play a pivotal role in building the security capability from the ground up, strengthening cyber maturity and helping shape the future direction of security across the business.

This is a broad, high-impact role where you'll combine hands-on security engineering with architecture, governance and strategic input. You'll work across Microsoft 365, Azure, Entra ID, AWS and hybrid infrastructure, improving identity, endpoint, cloud and data security while partnering with technical teams to embed security into major technology initiatives.

It's an opportunity to build rather than maintain. You'll establish security standards, mature policies and controls aligned to ISO 27001, drive security awareness, improve operational resilience and help create a security-first culture. As the security function grows, there is a genuine pathway into a future security leadership role.

Call, text or email if you have any questions or want to talk about the role.
