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. They make campaigns profitable for our first, affiliated games client, then bring external advertisers on board once the models are ready. Our edge is supply and SDK data from our own exchange that other DSPs don't have.



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. Own the commercial result:
Define what "good enough" means at each step: a baseline model on exchange SDK data, then install and ROAS models, then external advertisers.
Qualify in-app advertisers before they come on board, once the models are ready.
Lead data scientists, analysts and engineers, and decide who works in the squad.
Bring performance UA know-how into the squad, by hiring, coaching or partnering.
Work with the exchange teams on supply and data, with engineering leadership on infrastructure and hosting cost, and with finance on how gross profit is counted.
Requirements: Has built or scaled a performance DSP , ideally including a cold start. Commercial ownership. You have owned a P&L; or a commercial number, and you see clients and competitors as clearly as you see the system.
Performance UA economics for in-app advertising: Has led data scientists and engineers whose work you could judge.
Practical, hands-on use in your own commercial or product work, with the ability to describe the specific workflows you improved, the results, and how you validated the output.
Strong data analysis capability. You can pull and interrogate campaign, bidding and margin data yourself (bid rate, win rate, cost per install, ROAS by cohort). Based in or relocating to Barcelona , and able to work office-first.
