Our eligible talent get access to benefits such as health benefit contributions, retirement plans with match and flexible spending accounts. ## Description Working at the intersection of large-scale machine learning, pipeline engineering, and product innovation, the squad partners closely with Product, Engineering, and Data Science teams to build intelligent systems that improve how users experience content across the platform. In this role, you will play a central part in taking models end-to-end-translating ambiguous content challenges into robust, production-grade quality signals. What You'll Do * Work with other senior and staff engineers on machine learning initiatives from ideation, problem formulation, and prototyping through experimentation, deployment, and large-scale productionization. * Design, develop, and deploy machine learning systems and quality signals that operate across hundreds of millions of content items using both real-time and batch processing architectures. * Advance our clients capabilities in natural language understanding, multimodal AI, and content intelligence, with a focus on quality classification, ranking signals, and spam detection. * Build, evaluate, and iterate on ML and LLM-powered solutions using modern prompting techniques, retrieval systems, and advanced model orchestration approaches. * Audit, refactor, and mature existing early-stage models and pipeline foundations, optimizing them for production reliability, throughput, and scale. * Define rigorous evaluation methodologies utilizing golden datasets, precision/recall frameworks, offline benchmarking, and online experimentation. * Partner closely with Product Managers, Engineering Managers, Staff Engineers, and Data Scientists to influence technical strategy, roadmaps, and architectural trade-offs.
