Senior Product Manager

The Vibe team is a passionate, competitive bunch focused on one thing: allowing any marketer, any brand, of any size, to advertise on TV in under 5 minutes. We think fast, act fast, grow fast so advertisers can safely and precisely reach TV audiences, the largest digital audience in the US.

Vibe achieved profitability just 18 months post launch, growing revenue by 30+% every quarter since 2022, and we're already well on our way to reaching our 2025 goal of becoming the #1 TV Ad Platform.

Join us

You will join the Performance team, which sits at the core of Vibe's value creation engine.

The team is responsible for the systems that determine how budgets are spent, how bids are placed, and how performance is measured and optimised in a real-time bidding environment.

Working closely with Engineering, Data Science and commercial stakeholders, the Performance team builds and operates data-intensive, low-latency systems that directly impact advertiser ROI and platform growth.

Reporting to the VP of Product, you will own the product strategy and roadmap for Vibe's performance stack, including bidding infrastructure and performance measurement.

Your role is to ensure that algorithmic bidding decisions and measurement frameworks translate into measurable, causal performance improvements for advertisers, while respecting the real-world constraints of RTB systems.

This is a senior, highly technical product role, operating at the intersection of product, data and engineering.

• Bidding logic & optimisation

• Define and evolve bidding logic across pricing, pacing and inventory selection within the OpenRTB framework

• Own the roadmap for algorithmic bidding strategies balancing competing constraints (e.g. budget delivery, CPA / ROAS targets)
• Collaborate closely with Data Science to iterate on prediction models and optimisation strategies
• Design and refine bid shading mechanisms to reduce clearing prices while maintaining win rates

• Attribution & performance measurement

• Own integrations with measurement partners and tracking systems (e.g. MMPs, web pixels) to ensure data accuracy and reliability

• Design and ship incrementality frameworks (geo-lift, holdout groups, ghost ads) to measure causal impact beyond last-click attribution
• Define product requirements for performance reporting and dashboards, serving both technical and non-technical users

• Execution, analytics & delivery

• Translate complex performance problems into clear, actionable product requirements

• Write detailed specifications for backend engineers, including latency constraints, QPS handling and signal processing
• Use SQL and log-level data to investigate issues, validate hypotheses and size opportunities
• Drive prioritisation based on impact, feasibility and measurable outcomes

• 5+ years of experience in Product Management within Performance AdTech (DSP, SSP, measurement or optimisation platforms)
• Deep understanding of programmatic advertising, RTB and auction mechanics (first-price vs. second-price)
• Strong experience working with performance-based KPIs (ROAS, CPA, CPI)
• Solid statistical literacy, including experimental design, A/B testing, confidence intervals and significance
• Strong analytical skills, with hands-on experience using SQL and data exploration tools
• Comfortable operating in highly technical, data-intensive environments
• Comfortable working in a remote-first environment
• Perfect fluency in English

• Ownership of a strategic and revenue-critical product domain
• Direct impact on how advertiser performance is optimised and measured
• Work on complex, real-time systems combining product, data science and engineering
• High autonomy and influence within the product organisation
• Opportunity to shape Vibe's long-term performance and measurement strategy

• Very competitive compensation (salary and stock-options/BSPCE)
• Remote-first (in France or elsewhere) with the option to work on-site in an ultra-cozy coworking space in the heart of Paris (Morning Laffitte)
• Health insurance (Alan)
• Meal vouchers (Swile)
• Two annual offsites
• Guaranteed childcare placement
