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 engineering or product engineering leadership role, managing teams of 15–20+ across multiple disciplines.
- Strong working knowledge of machine learning and data science concepts — sufficient to credibly manage, grow, and set direction for a Data Science organization.
- Solid grounding in data engineering, analytics, and BI, with the ability to operate fluently across all of them.
- Bachelor's or Master's degree in Computer Science, Engineering, or a related field.
- Excellent stakeholder management skills and the ability to operate with significant ambiguity in a fast‑moving, high‑ownership environment.
- Advanced Business English, particularly in writing and speaking.
- Willingness to relocate to Barcelona.

Nice to Haves:

- Prior experience at a full‑stack ad tech company (exchange + mediation + DSP).
- Experience building or scaling machine learning‑driven bidding/prediction systems specifically in mobile UA or programmatic advertising.
