Job description

Job Description

Marketing that actually gets close to the business.

We’re The Onset - a specialist recruitment business deeply connected to Australia’s technology ecosystem. We work with ambitious companies, brilliant industry experts and a wider group of specialists across data, AI, design and transformation through The Omnia Collective.

We’re growing our marketing team and looking for someone who wants more than a narrow coordinator role. You’ll help us build smarter campaigns, experiment with AI and automation, support client engagement, work across the wider Omnia group and get involved in the events and experiences that bring our community together.

It’s a broad role by design. One day you might be building a target-account campaign with a recruitment leader; the next, testing an AI workflow, helping activate an industry event or pulling together the data that tells us what is actually working.

What you’ll get stuck into

• Build targeted B2B campaigns around the clients, sectors and communities we want to engage.

• Experiment with AI and automation to make research, campaign delivery, follow-up and reporting smarter.

• Work closely with our recruiters on client outreach, useful market content, case studies and sales enablement.

• Coordinate website, SEO/AEO/GEO, email and digital activity and help us turn performance data into better decisions.

• Become a key link between The Onset and Omnia Collective, working alongside teams across AI, data, design and transformation.

• Help deliver client, community and industry events - from the campaign and guest experience through to the practical set-up and follow-up.

• Keep the marketing engine organised: systems, assets, reporting, campaign workflows and the details that make good ideas happen.

You’ll thrive here if…

• You have marketing experience under your belt in B2B, growth, campaigns or marketing operations - and you’re ready for more ownership. Technology sector, recruitment or professional-services experience is useful, not essential.

• You are already using AI as a marketing and productivity tool. Maybe you use ChatGPT or Claude every day, have built agents and automations, or are the person who always asks, “could we make this easier?”

• You like working close to sales and clients and can see the difference between useful engagement and marketing noise.

• You are organised enough to keep multiple things moving, but curious enough to keep improving how they are done.

• You are comfortable with digital tools and data, without needing to be a technical specialist.

• You have a hands‑on style. We are a small team: no one is too senior to help set up a room, move a box, capture content or solve the thing that needs solving.

• You enjoy people. This role crosses recruiters, leaders, clients, community members and teams across the wider Omnia group.

Why this one is interesting

• You’ll work alongside our Brand & Community Specialist, with room to build complementary expertise in growth, AI and marketing operations.

• You’ll have access to experts across Onset and The Omnia Collective and exposure to the way AI, data, design and transformation are changing businesses.

• You’ll work directly with senior leaders and recruitment consultants rather than sitting several layers away from the commercial conversation.

• You’ll get genuine variety: campaigns, AI, events, content, systems, client engagement and community.

• There is a clear path to grow as your ownership and capability expand.

• We offer a flexible WFH day, ongoing development, team events and a lively Surry Hills office environment.

A note on experience

We care more about capability, curiosity and attitude than finding someone who has done this exact job before. If you have a strong marketing foundation, like learning new technology and want to be close to the action in a growing business, we would like to hear from you.

Sponsorship is not available for this role and Australian based, B2B experience is preferred.
