Head of Customer Success

BidMachine Exchange – a fast-growing global programmatic exchange built for the future of in-app advertising.

BidMachine operates with a strong US foundation and an international presence, with teams across Warsaw, Barcelona, Parkland (FL), and remote experts around the world.

We combine deep AdTech expertise, proprietary technology, and a data-driven mindset to deliver transparency, performance, and efficiency in the mobile advertising ecosystem.

Why BidMachine?
At BidMachine, we are building more than an exchange — we are shaping the infrastructure that powers fair, efficient, and scalable in-app programmatic advertising.
Our mission is to create a high-performance marketplace where publishers maximize value and advertisers access premium inventory with full transparency and control.
We are proud of our technology, our ambitious vision, and our globally distributed team of talented professionals who continuously raise the bar in AdTech.

Here’s what we value, and what we hope you do too:

Ownership & Accountability
We move fast, take responsibility, and think like builders. Every team member has a direct impact on product growth and market success.

Data-Informed Excellence
We leverage data to make smarter decisions, optimize performance, and build scalable solutions that deliver measurable results.

Innovation & Technical Depth
We solve complex programmatic challenges with cutting-edge technology and a deep understanding of the ecosystem.

Global Collaboration
We work across cultures, time zones, and disciplines — united by shared goals and high standards.

Ambition & Impact
We are here to build something significant — a best-in-class exchange that competes with the strongest players in the market.

BidMachine is looking for a hands-on Head of Customer Success (Mediation) to keep and grow the publishers that already run on our mediation platform.

This role combines customer success, account management and technical account management across our entire mediation business. Once a publisher has been signed and integrated, it’s yours: you’ll know what each client needs and what competitors are offering them, act as their technical counterpart on integration, SDK and performance issues, and work with Product and Engineering to drive the fixes and improvements that keep them with us.

Success here isn’t measured by activity or reports. It’s measured by the share of accounts you keep, the gross profit the portfolio brings, how efficiently your team runs it, and how satisfied publishers are.

You’ll lead a small team and work closely with the squads that sign new publishers, so that every handover is smooth and nothing gets lost. 

This is a highly operational role for someone who has managed mediation clients before and knows that standard account management isn’t enough. The largest platforms charge publishers no mediation fee, so clients stay because of the value and the relationship. We’re looking for someone who finds new ways to get close to clients, so they pick up the phone when you call.
