Senior AdTech Architect

About the role

Rakuten TV, a video streaming platform based in Barcelona, is looking for a Senior AdTech Architect to design and lead the build-out of its programmatic advertising stack. This is a greenfield role with no existing architecture to inherit, reporting directly to the CPO and owning both the technical strategy and day-to-day execution. The role also shapes how the company approaches advertising as a business and works closely with commercial and ad operations teams.

Key responsibilities

• Design and own the end-to-end architecture of the programmatic stack: bid handling, auction logic, CTV ad delivery and the impression and measurement pipeline.
• Own the build-vs-buy decision for each part of the stack, with a clear point of view backed by experience.
• Contribute to the advertising strategy with the CPO and commercial leadership, including revenue model fit, standards and integrations, and product differentiation.
• Set technical direction for IAB standards, consent chain management and advertiser measurement, and manage technical relationships with SSPs, DSPs and measurement partners.
• Lead a small team (PM, AdTech Specialist, AdTech Engineer) with a hands-on approach, and help define the team's structure as it grows.

Required profile

• 8-12 years in AdTech, with a significant portion in programmatic and CTV.
• End-to-end ownership of an RTB or bid management system design.
• Experience making or influencing build-vs-buy decisions on critical stack components.
• Comfortable in commercial conversations such as floor pricing, yield trade-offs and DSP relationships.
• Background in a broadcaster, streaming platform, SSP, DSP or ad technology vendor.

Required skills

• OpenRTB 2.x / 3.0, VAST / VMAP / SCTE-35, CTV ad integration and real-time event streaming.
• First-party audience data architecture (identity resolution, UID2, ID5).
• SSP/DSP ecosystem, programmatic economics, yield management and European compliance (GDPR, TCF 2.x).
• Nice to have: direct DSP integrations, cleanroom data collaboration, IAB segment translation, AI-native buying channels.

What we offer

• Hybrid work, flexible hours and Friday afternoon off.
• Training resources, free language classes and access to Wellhub.
• Modern offices near Barcelona beach, wellbeing and mental health platforms.
• Medical insurance or extra funds for meals, commuting and childcare.
