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

Responsibilities

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.
