BidMachine's UA business unit is looking for an experienced Head of Product Engineering to own the technical and product vision of our demand-side platform (DSP) — the engine that runs managed-service campaigns for advertisers today, with a self-service version on our roadmap.
You will unify Data Science, Data Engineering, Data Analytics, BI, and our bidding/prediction stack into a single, coherent product, replacing today's fragmented workflow with one clear roadmap and one set of aligned decisions. This is a hands‑on leadership role: you'll sit above our Data Science function, work daily with our go-to-market and sales leadership, and carry direct influence over how we compete with the handful of full‑stack players (exchange + mediation + DSP) in this industry.
Location: Barcelona, Spain
Responsibilities:
Own the end-to-end technical and product roadmap for the UA DSP, from bidding and prediction through to reporting and BI.
Unify Data Science, Data Engineering, Data Analytics, BI, and backend engineering (predictor/bidder) into one product function with consistent,



aligned decision‑making.
Lead, grow, and mentor a team of roughly 20 across engineering, data science, and analytics; accelerate the growth of the existing Data Science function.
Partner closely with the Go-to-Market/Revenue lead and Head of Sales to translate market opportunities into technical feasibility assessments and vice versa.
Drive the long‑term transition from managed‑service to self‑service tooling for advertisers.
Bring engineering rigor and a genuine product mindset — at BidMachine, "product" means engineers who understand the business and can set direction, not a separate function.
Move quickly from close collaboration on direction‑setting to independently owning and defending product strategy.
Requirements:
~10+ years of experience in software engineering, with demonstrated hands‑on experience having built and scaled a DSP or comparable real‑time bidding platform.
~5+ years in a senior e
