Responsibilities
Architect for Scale, Intelligence, and Ads Quality: Design and evolve the platforms supporting Ads selection, targeting, ranking, pacing, creative optimization, delivery, and measurement. Build systems that prioritize relevance, transparency, trust, and measurable advertiser and user value
Advance Intelligence in Production: Partner with ML and Data Science teams to operationalize models for ranking, bidding, feedback optimization, and pacing. Define architectural patterns for online inference, model safety, explainability, and low-latency, high-throughput decision-making
Evolve the Ads Platform: Advance the core systems powering Fetch’s Ads: attribution, incrementality measurement, real-time signals, brand safety, fraud mitigation, and revenue integrity. Pioneer new approaches that raise both advertiser ROI and user experience quality
Define System and Experience Quality: Establish company-wide standards for ad and user experience quality, integrating performance, reliability, and relevance metrics. Establish platform-wide standards for performance, reliability, trust, and relevance
Lead Through Influence and Product Partnership: Drive architectural alignment across Ads, Data, Platform, and Product teams. Translate tradeoffs into measurable business outcomes: improved ROI, latency reduction, yield lift, and better developer velocity
Scale Experimentation & Learning Systems: Improve experimentation frameworks, incrementality infrastructure, and rapid-iteration tooling. Enable faster learning loops across Ads algorithms, UX surfaces, and delivery pipelines
Accelerate Innovation Velocity: Champion AI-assisted development, scenario testing, simulation environments, and feedback-driven observability. Enable engineering teams to iterate faster while protecting user trust, system integrity, and revenue signals
Mentor & Multiply Engineering Impact: Coach senior engineers and rising technical leads, elevating standards for architectural clarity, AI-driven design, measurement rigor, and thoughtful system evolution. Amplify impact through reusable frameworks and technical patterns
Model Technical Excellence & Responsible AI: Promote principles of responsible AI, transparency, model accountability, and safety-by-design. Shape the engineering culture around intelligent system build practices
Qualification
Required
Experience with Ads or performance marketing systems (ranking, pacing, delivery, incrementality, attribution)
Proven ability to design high-scale ad-serving or recommendation pipelines with strict relevance, latency, and reliability requirements
Deep expertise designing or scaling intelligent, data-intensive systems used for personalization, ranking, targeting, bidding, or real-time optimization
Strong intuition for data quality, attribution accuracy, and revenue-integrity metrics
Demonstrated leadership of cross-org technical initiatives that improved reliability, velocity, monetization performance, or intelligence
Experience bringing ML-driven systems to production: feature pipelines, inference, safety validation, and model governance
Fluency in modern software ecosystems (Kubernetes, event streaming, CI/CD, observability tooling, AI-assisted development workflows)
Ability to influence technical strategy and explain architectural decisions in business terms
Growth mindset: thrives in high-velocity environments, with a relentless focus on measurable outcomes and system evolution
Preferred
Experience with learning-to-rank, bidding, pacing, or real-time feedback optimization systems
Familiarity with LLM agent frameworks (LangChain, Semantic Kernel, Haystack) or RAG systems
Demonstrated experience improving observability, latency, or cost efficiency in intelligent systems
Exposure to multi-modal intelligence or contextual ranking models using structured and unstructured data
Strong judgment around AI integration: where it drives meaningful Ads performance versus where classical optimization is more effective
