Responsibilities
Design, build, and iterate AI and ML-powered ranking and relevance systems (including candidate generation, filtering, personalization, bandits, and learning-to-rank) that balance engagement, quality, and safety while meeting latency and reliability SLOs
Develop features and embeddings for users, content, graph, temporal, and safety signals; establish feature contracts, offline backfills, and online freshness
Stand up vector retrieval and RAG pipelines for semantic search, content understanding, and safety heuristics; tune retrieval quality, token/latency budgets, and evaluation
Build and operate online inference and batch scoring services for LLMs and ML models; optimize throughput, cost, caching, and autoscaling; introduce GPU-aware scheduling where appropriate
Partner with Data Platform on data movement and pipelines (batch and streaming) that power ranking models and analytics; ensure data quality, lineage, documentation, and observability
Partner with Data Science to frame metrics and hypotheses, design trustworthy experiments, analyze results, and productionize improvements
Productionize models end-to-end (training, evaluation, versioning, registries, rollouts, shadowing/canary, rollback) with strong CI/CD and infra-as-code practices
Establish ML observability (data/feature drift, model performance, safety thresholds, online/offline eval, dashboards and alerting) to maintain quality over time
Collaborate cross-functionally with product, design, platform/infra, safety, and CX to align on goals, roadmap, and risk management
Contribute to engineering excellence through documentation, code reviews, reliability improvements, and mentorship to junior engineers
Qualification
Required
3+ years of ML engineering or recommender-systems experience (or equivalent), including shipping production models and improving them iteratively
Strong software engineering fundamentals with proficiency in Python and SQL; experience building reliable services and data pipelines at scale
LLM and AI inference experience, including prompt/program design, evaluation frameworks, agentic workflows, or online performance optimization
Data pipelines and orchestration (batch and streaming), data quality/observability, and schema/feature contract management
ML operations (model registries, feature stores, experiment frameworks, offline/online evaluation, rollouts, and monitoring)
Experimentation mindset with practical A/B testing design, metric selection, and rigorous analysis in partnership with Data Science
Clear, pragmatic communication and the ability to collaborate across product, design, and engineering to drive outcomes
A hunger to learn more about AI and ranking at production scale
BS/MS in Computer Science, Machine Learning, or equivalent practical experience
Preferred
Experience with social feeds, marketplace dynamics, or personalization at scale
Hands-on experience with ranking/relevance, candidate generation/two-tower models, embeddings/vector search, contextual bandits, or RAG or retrieval-enhanced workflows
Experience with content safety and quality signals (e.g., NSFW/abuse detection, watermarking, spam/fraud patterns) and ranking-time mitigation
Knowledge of privacy, compliance, and responsible AI considerations in production ML
Exposure to Go or other strongly typed languages used in high-performance backends
