Business Development Manager, Publisher Partnerships in London

Born from deep roots in gaming media, Omnidex (Part of the Dexerto Media Group) was created to give advertisers access to a trusted network of premium publishers, all unified through direct technology integrations.

Omnidex turns these unique publisher relationships into performance, powering smarter targeting & higher engagement through unique contextual signals and proprietary first-party data, and high-impact formats that feel native to the content audiences love.

The Role

Omnidex is seeking a highly ambitious Publisher-facing Business Developer to spearhead the growth of our supply.

In this role, you will own the full lifecycle of publisher acquisition and relationship management.

From prospecting and pitching to negotiation, onboarding, and long-term account expansion.

You will play a central role in shaping the future of Omnidex's SSP offering by developing a robust network of premium publishers and strategic supply partners.

This is a high-impact, externally-facing position that requires strong commercial instincts, ad-tech fluency, and the ability to build and maintain deep partnerships across the digital publishing landscape.

Travel will be required for industry events, conferences, and partner meetings.

Success in this role means consistently delivering new business, and providing meaningful insights & initiatives that drive value for both our publisher partners and the business.

• What We Need
• A publisher-facing dealmaker with experience on the sell-side of ad tech.

Someone who can build a pipeline from scratch: prospect, outreach, run meetings, and keep deals moving without being chased.

• A strong negotiator who is comfortable owning commercial conversations and closing deals.
• Someone who understands programmatic: supply paths, header bidding, SSPs, and how publishers think about yield and monetization.
• A relationship builder who can maintain trust and relevance with partners over the long term.
• A self-starter who is motivated by targets and isn't afraid of owning a number.
• Someone who is comfortable traveling to events, conferences, and publisher meetings when needed.

What You Will Do

• Identify, prioritize, and qualify publisher prospects aligned with Omnidex's strategy (gaming, entertainment, lifestyle, and beyond).
• Outreach, intro calls, value proposition, product walk-throughs, handling objections, commercial negotiation, and closing.
• Work with legal and leadership on commercial terms, pricing models, and partnership structures that make sense for both sides.
• Partner with Ad Ops / Tech / Product to ensure integrations (SSP, header bidding, direct connections, etc.) are smooth and fast.
• Run regular check-ins and reviews, spot upsell/cross-sell opportunities, and proactively propose ideas to grow their revenue with us.
• Represent Omnidex at industry events, conferences, and networking meetups; bring back intelligence on trends, competition, and opportunities.
• Feed publisher needs, market gaps, and feature requests back into Product and leadership to help shape our roadmap and supply strategy.
• What You Need To Qualify
• 3+ years in a commercial, publisher-facing role in ad tech (SSP, ad network, publisher BD, programmatic partnerships, or similar).
• Proven track record in closing publisher or supply deals and hitting revenue or acquisition targets.
• Hands-on exposure to programmatic monetization (e. g. SSPs, header bidding, GAM/Ad Manager, PMPs, Prebid, or similar).
• Strong communication skills: you can explain complex things simply and negotiate clearly without burning bridges.
• High level of ownership and accountability – you're used to running your own pipeline and don't wait to be told what to do next.
• Comfortable travelling for events and partner meetings when needed.

Why should you work for us?

• Real ownership of the supply side. You're not "slotting into a mature machine"; you're helping build the engine.
• Direct impact, not busywork. You'll see a clear line between the deals you bring in and the growth of the business.
• Ad tech with an edge. We sit at the intersection of gaming, entertainment, and performance - you'll work with publishers and formats people actually care about.
• Smart, lean team. No huge corporate hierarchy. You'll work closely with decision-makers and be heard.
• We're super ambitious with big goals, and you'll be part of a team that's consistently grown by 50% each year.
• We only hire the best and strive to compete at the highest level, so you'll be working with a team of A-players.

This job isn't for you if

• If you've never worked in ad tech / publisher monetization.
• If you're someone who needs handholding and can't work independently.
• If you struggle in fast-paced, high-stakes environments.
• If you're uncomfortable being measured on targets (publisher signings, revenue, pipeline metrics).
• If you hate cold outreach, networking, or negotiation and prefer a purely internal or operational role.
• If you don't want to travel to industry events or meet partners in person from time to time.
• If you're looking for a slow, predictable environment with minimal change.
