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 General Manager DSP.

This role owns the commercial result of our demand-side platform (DSP) for in-app advertising on iOS and Android, from model to campaign to gross profit. The person in the seat decides which parts of the DSP get built, in what order, and which ideas get dropped. They make campaigns profitable for our first, affiliated games client, then bring external advertisers on board once the models are ready. Success is measured as gross profit per person in the squad, so the squad stays small. Our edge is supply and SDK data from our own exchange that other DSPs don't have. Turning that edge into installs that pay back is the job.

The platform is being built so that campaigns learn and scale without an account manager or an engineer stepping in. As more of the bidding and campaign work is automated, this role concentrates on what stays human: what to build and what to drop, the commercial calls with advertisers, and when an exception is worth asking for. One honest note: the DSP is early, it loses money today, the competitors you'll be measured against have been doing this for years, and each quarter of investment has to be argued for with results.

Location: Barcelona, Spain.

Key Responsibilities

Own the commercial result

Own gross profit per squad employee and the P&L behind it, including experiment and hosting costs.
Write the plan the business backs, and report against it every week.

Decide the build sequence

Decide which DSP components get built, in what order, and which ideas get dropped.
Define what "good enough" means at each step: a baseline model on exchange SDK data, then install and ROAS models, then external advertisers.

Make campaigns profitable

Win more install supply at a price that works, and lift return on ad spend for the first client.
Fix the system rather than rescuing campaigns by hand.

Bring on external advertisers

Qualify in-app advertisers before they come on board, once the models are ready.
