Full Job Description
đź“‹ Description
- • Own the technical vision and roadmap for Etsy’s Search Ranking team, translating marketplace strategy into scalable ranking systems that surface the most relevant, inspiring, and human-centered listings for 90+ million active buyers.
- • Lead, mentor, and grow a cross-functional group of 8-12 engineers and applied scientists who design, train, and deploy large-scale ranking models that process hundreds of millions of listings in milliseconds while balancing relevance, personalization, and marketplace health.
- • Drive end-to-end experimentation—from hypothesis formation and offline feature engineering to online A/B tests and production rollouts—ensuring every iteration measurably improves buyer engagement, conversion rate, and seller success.
- • Partner daily with Product, Data Science, Design, and Infrastructure teams to prioritize initiatives, define OKRs, and allocate resources so that ranking improvements directly advance Etsy’s growth and revenue targets.
- • Champion engineering excellence by instituting rigorous code review, automated testing, model evaluation, and on-call practices that keep latency low, availability high, and model drift under control across distributed systems spanning multiple regions.
- • Architect and evolve the underlying data pipelines, feature stores, and vector-search infrastructure that feed ranking models, ensuring they remain performant, cost-efficient, and privacy-compliant as catalog size and query volume scale.
- • Foster a culture of psychological safety, continuous learning, and inclusive leadership—running blameless postmortems, sponsoring conference attendance, and creating growth plans that turn junior engineers into senior technical leaders.
- • Translate complex technical concepts into clear narratives for executives, influencing multi-year investment decisions and aligning stakeholders around search quality, fairness, and long-term marketplace sustainability.
- • Oversee the transition from classical learning-to-rank models toward modern deep-learning and transformer-based architectures, including exploration of generative retrieval and semantic search techniques that deepen buyer delight.
- • Monitor real-time dashboards and anomaly detection systems to proactively identify ranking degradation, coordinate rapid incident response, and conduct root-cause analyses that prevent recurrence.
- • Balance short-term wins (e.g., query-category intent improvements) with long-term bets (e.g., multimodal embeddings for visual search) while maintaining a disciplined experimentation budget and technical debt ledger.
- • Represent Etsy externally by publishing research, speaking at conferences, and contributing to open-source projects that advance the broader information-retrieval and responsible-ML communities.
🎯 Requirements
- • 5+ years leading engineering teams that built and operated large-scale search ranking, recommendation, or ads systems serving >100 M queries/day.
- • Deep expertise in information retrieval, personalization algorithms, and modern ML frameworks (TensorFlow, PyTorch, XGBoost, etc.) with a proven record of shipping models to production.
- • Demonstrated success driving measurable business impact through rigorous A/B testing, causal inference, and data-driven iteration in consumer-facing products.
- • BS, MS, or PhD in Computer Science, Engineering, or related quantitative field (or equivalent practical experience).
- • Exceptional communication skills with the ability to distill complex technical trade-offs into clear recommendations for both technical and non-technical audiences.
🏖️ Benefits
- • Total compensation package of $226,000–$294,000 base salary plus annual performance bonus and meaningful equity grants.
- • Hybrid work flexibility with 1–2 days per week in Etsy’s Brooklyn Hub or SF Bay Area offices, plus ergonomic home-office stipend.
- • Comprehensive health, dental, vision, life, and disability insurance for you and dependents, plus generous parental leave and family-planning support.
- • Annual professional-development budget, conference sponsorships, and dedicated 10% “hack-week” time for exploration and innovation.
