The Publisher Development Manager is a commercially focused, hands-on role responsible for growing GumGum’s publisher business and managing the success of existing publisher partnerships across the Australian market. This role combines publisher development, strategic sales, and publisher success responsibilities. The successful candidate will build and deepen relationships with leading Australian publishers, identify and close new supply opportunities against a formal individual sales quota, and serve as a trusted senior point of contact for GumGum’s existing publisher partners.

The role will focus on developing strategic relationships with major publishers including Nine, Network 10, News Corp Australia (NCA), Seven, and other priority media owners in the market. The Publisher Development Manager will represent GumGum at relevant industry events, organise and lead publisher meetings and QBRs, and ensure that publisher partnerships deliver long-term commercial and operational value. Alongside the external relationship and sales responsibilities, this person will own the day-to-day operational success of publisher accounts in GumGum systems, including publisher onboarding, coordinating with GAPS to ensure integrations work correctly, setting up publishers in Pub Manager, ensuring alignment is completed, monitoring internal reporting, and maintaining compliance with industry requirements such as ads.txt, sellers.json, and TID. As GumGum’s key publisher contact in Australia, this role will work proactively with internal teams to share regular updates on supply changes, publisher developments, performance trends, data analysis, supply insights, risks, and strategic recommendations.

Note: GumGum fosters a flexible work environment, offering GumGummers the ability to work either in-office or remotely/from home. However, for occasional in-person collaboration, we kindly ask that this position be located within a 'commutable' distance to our office.

What You'll Achieve

• Build strategic, long-term relationships with Australia's biggest media owners, including Nine, Network 10, News Corp Australia, and Seven.
• Own your publisher sales pipeline from end to end, identifying, negotiating, and closing new partnerships against your own sales quota.
• Craft compelling commercial proposals and partnership plans grounded in publisher priorities, market insight, and performance data.
• Spot and unlock expansion opportunities with existing partners across new products, formats, inventory types, and markets.
• Be the face of GumGum at industry events and publisher forums, raising our profile across the Australian market.
• Serve as the trusted primary contact for a portfolio of publisher partners, leading regular meetings and QBRs packed with performance updates and strategic recommendations.
• Drive publisher onboarding and launch readiness, from Pub Manager setup and alignment to partnering with GAPS so every integration runs smoothly.
• Keep the supply chain healthy and compliant (ads.txt, sellers.json, TID), and keep local teams up to date on supply changes, performance trends, and risks.

Skills You'll Bring

• 5+ years in publisher development, partnerships, strategic sales, publisher success, or account management within digital advertising or ad tech.
• Established relationships with senior stakeholders at major Australian publishers, such as Nine, Network 10, NCA, or Seven, plus a strong read on the local media market.
• A proven record of closing commercial partnerships against a formal sales quota, backed by sharp sales strategy and negotiation skills.
• Deep knowledge of the programmatic ecosystem (DSPs, SSPs, ad exchanges, and publisher monetisation models), with CTV or video experience a plus.
• Hands-on familiarity with publisher integrations such as Prebid, JavaScript tags, and server-to-server setups, plus the ability to troubleshoot them with technical teams.
• Confident communication and presentation skills, including turning complex technical and performance topics into clear commercial recommendations for executive audiences.
• Strong analytical instincts and top-notch organisation, so you can juggle a pipeline, an account portfolio, and onboarding projects all at once.
• An entrepreneurial, solutions-focused mindset, fluency with Google tools, CRMs, and reporting tools, and a base in Australia with the ability to work from the Sydney office twice a week.
