Head of Customer Success
BidMachine
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:
Seek the Truth and Say It with Care
We find the truth together, and nobody owns it, the CEO included. Stories, perspectives and beliefs can be personal. Facts can’t.
Leverage Data to Build Product
Our decisions start from data. We build systems rather than one-off tasks, use AI agents in our daily work and automate whatever is manual. When numbers don’t match, we fix them.
We Work Together to Serve Others
No closed doors between teams. We share what we learn and win as one company first.
Insist on Higher Standards
We don’t settle for “good enough”. We question it and push for better.
Passionate Curiosity Fuels Perseverance
We ask “why”, take on ambiguous problems and keep going when they get hard.
Lean Startup Mentality: Start Small, Iterate Quickly
Think big, ship an MVP first and learn fast. No big-bang releases.
Ownership and Accountability
We work in small squads so each team owns its result end to end and has the freedom to get there. Go deep in your craft and wide enough to own the whole outcome. Escalate blockers early, admit mistakes, fix the damage and learn.
BidMachine is looking for a hands-on Head of Customer Success (Mediation) to keep and grow the publishers already running on our mediation platform.
The role brings together Customer Success, Account Management and Technical Account Management across our whole mediation business. Once a publisher is signed and integrated, it's yours. You'll know what each client needs and what competitors are offering them. You'll be their technical counterpart on integration, SDK and performance issues, and work with Product and Engineering on the fixes and improvements that keep them with us. With our most important publishers, you'll build partnerships deep enough for our product teams to build on.
We don't measure success by activity or reports. We measure it by the gross profit your portfolio brings and how efficiently your team delivers it, along with how many accounts you keep and how satisfied publishers are.
You'll lead a small team and work closely with the squads that sign new publishers, so every handover is smooth and nothing gets lost.
Location: Barcelona, Spain
Own the mediation book of business
Take over every publisher once the growth teams have signed and integrated them, and own the account from then on.
Be accountable for retention, account health and growth across the whole book.
Spot accounts that are drifting and act before the publisher does.
Customer success and account management
Know what each important publisher needs, what they are planning and what competing platforms are offering them.
Get close to clients in ways that go beyond standard account management: new services, new proposals, events, and the kind of relationship where the client answers when you call.
Measure satisfaction through customer success surveys.
Technical account management
Act as the publisher's technical counterpart on integration, SDK and performance issues.
Translate a client's problem into a clear request for product and engineering, and follow it through to a fix.
Minor product improvements
Drive the small product changes needed to keep accounts and improve their experience. Larger product work sits with other teams.
Grow gross profit and team efficiency
Grow gross profit from the existing portfolio.
Improve gross profit per employee over time by moving rule-based work onto automation and keeping the strongest people.
Lead the team
Choose the people the work needs, set priorities and coach the team.
Work closely with the teams that sign new publishers, so handovers lose nothing.
Watch the market and write it down
Track competing mediation platforms and which of your accounts they target.
Keep plans, decisions and the state of key accounts written down where the team can see them.
Technical depth. You're technical enough to read an SDK release, describe an integration problem precisely and challenge an engineering estimate.
Team and product. You've built a team and turned client needs into product changes that shipped.
Strong data analysis capability. You feel comfortable with account-level data (requests, fill rate, eCPM, revenue).
Demonstrated AI experience, required. You use AI tools in your work and can show what they improved and how you checked the output.
Mobile Ad Mediation experience, ideally at a platform that grew while you were there.
With a powerful product, strong market positioning, and a team that strives for excellence, BidMachine offers a unique opportunity to grow, innovate, and make a tangible impact in the programmatic advertising space.
