Growth Marketing Manager

We’re now hiring a Growth Marketing Manager to own and accelerate our demand generation performance. This is a hands‑on, performance‑first role at the centre of our FY26/27 growth strategy.

What You’ll Do
Drive a step‑change in marketing‑sourced pipeline through high‑performing demand programmes and better lead quality.
Sharpen lead scoring, nurture, segmentation and SDR handoff to make the funnel more efficient.
Build AI into everyday marketing workflows to improve speed, personalisation and performance.
Optimise channel mix, conversion rates, campaign structure and targeting to cut cost without dropping quality.
Establish a steady experimentation rhythm – transparent hypotheses, tracking and learning loops tied to revenue.

What Success Looks Like

You’ll own the numbers.



Within your first year, you’ll be clearly accountable for pipeline performance, with AI‑enabled improvements across the funnel and stronger alignment between Marketing and Sales. You’ll grow marketing‑sourced pipeline year on year, lift monthly MQL and SQL volume, and reduce the cost of each qualified lead.

What We’re Looking For
3–5 years in B2B SaaS, technology or high‑growth environments, with real ownership of demand generation.
Hands‑on with HubSpot and Salesforce; comfortable with GA4, attribution tools and campaign platforms.
AI‑native – you use AI as genuine operating leverage, not novelty.
Commercially wired and outcome driven. You’re comfortable owning a target and making decisions anchored in cost and revenue.
A growth mindset and a bias to ship. You want accountability, not a maintenance role.

Ready to Build?

If you want meaningful pipeline ownership in a quick‑moving, high‑autonomy team, we’d love to hear from you.
