Investment Director (Media)

Job Description

About Overdose.

Overdose is a global digital commerce agency working with some of the largest and most ambitious retail and B2B brands across Australia, New Zealand and further afield. We design, build and migrate commerce platforms, run marketing, SEO and GEO, have a scaling Data practice, and we increasingly do all of it AI-native. 

We call this Complete Commerce.

The Opportunity

This is a senior individual contributor role with enterprise-wide influence across our Australian client portfolio. Reporting directly to the Digital Marketing Director, Australia, you’ll act as the first internal consultant of this kind within the broader marketing team. You’ll be close to account-level realities, while bringing the perspective to identify patterns, opportunities, and improvements across the portfolio.

You’ll shape the systems and standards behind better enterprise performance, from forecasting and media investment planning to QBR quality and consistent ways of working. Your impact will be visible in the frameworks that sharpen decision-making, the commercial recommendations that influence client investment, and the strategic capability you build across the team.

You’ll lead through expertise, clarity, and influence rather than direct reports. It’s an opportunity to define a new kind of strategic role at Overdose and make a visible impact across some of our most important client relationships.

What you’ll own:

• Own media planning and forecasting: Lead holistic media planning across the Australian portfolio, owning the forecasting methodology and applying Marketing Mix Modelling to guide budget decisions that materially shape client outcomes.
• Client portfolio oversight: Hold a portfolio-level view across all enterprise accounts, spotting risks and opportunities and run the quarterly strategy reviews that shape what happens next.
• New business and growth: Identify cross-sell and upsell opportunities, lead new platform and channel recommendations, and bring a senior paid media perspective to pitches and retainer growth.
• Operational excellence: Standardise QBR formats, reporting standards, and ways of working the whole team runs on, and own the quarterly business review process end to end.
• Team enablement: Coach senior team members through frameworks, structured reviews and direct mentoring. Influence the strategic capability of the paid media practice by setting standards the whole team rises to.
• AI and innovation: Pilot and evaluate AI-assisted tools for media planning, bidding and creative testing, and model best-practice AI usage for the wider team.

What you’ll bring:

What we're really looking for is genuine strategic thinking and a real track record across enterprise accounts. If you've built forecasts, commercial recommendations or ways of working that actually shaped how a client invested, we’d love to hear from you.

You will probably have:

• A track record of operating at a senior strategic level in paid media, ideally within a performance or digital commerce agency.
• Comprehensive, certified knowledge of Google Ads (Search, Pmax, AImax, Display, Demand Gen, YouTube) and major social platforms (Facebook, Instagram, TikTok, Pinterest and similar).
• Deep cross-channel knowledge of how paid search, paid social, organic search and programmatic work together to drive commercial outcomes.
• Experience applying Marketing Mix Modelling to cross-channel budget optimisation, media attribution and incrementality measurement.
• Strong commercial acumen across margin, growth and client retention, backed by a proven track record in media planning and financial forecasting across enterprise accounts.
• Experience building or improving operational processes including QBRs, reporting standards and ways of working.
• Active use of AI tools in a media planning or strategy context, with a clear view on where AI adds real value and where human judgement matters.
• Exceptional written and verbal communication skills, with the ability to simplify complex concepts and present confidently to senior stakeholders.

Why Join the OD Crew?

We work by design, not by default. A select client model means the work is deliberate, the relationships are real, and your impact is measurable. 

Being AI-native is not a positioning line. It shapes how every person here delivers. You will have the tools to move fast and a team that builds with AI every day.

We are serious about people. A safe, supportive environment shapes how we work, grow and lead. Real ownership. Direct access to leadership. A team worth showing up for.

The role perks and benefits:

• Hybrid working arrangements.
• Two Wellness days per year.
• Additional day of leave to celebrate your birthday.
• Annual training allowance.
• Access to globally recognised courses and programs.
• Parental Leave support that goes beyond the standard.

If this sounds like the kind of strategic challenge you’d enjoy, we’d love to hear from you. Tell us about a piece of work you’re proud of, the impact it had, and how you used AI to improve your thinking or execution. That is what matters most to us.
Overdose is an equal opportunity employer. We welcome applications from all backgrounds and are committed to a fair and inclusive recruitment process.
