Staff Applied Machine Learning Engineer - Intelligent Data, Signals & Systems
Block, Inc. is seeking a Staff Applied Machine Learning Engineer to join their Intelligent Data, Signals & Systems team. This role focuses on developing production machine learning systems that convert customer behavior, product context, model outputs, and feedback loops into reliable signals utilized by recommendations, ranking, risk-aware decision-making, growth, and customer intelligence systems. The position is available remotely or in the Bay Area, California.
In this role, you will build and operate production ML systems that transform customer and product context into trusted signals, rankings, recommendations, and decision capabilities. You will design production data and signal contracts that define intended use, freshness, provenance, confidence, eligibility, and calibration for downstream consumers. Additionally, you will own ranking, retrieval, recommendation, search, propensity, and next-best-action systems end-to-end, from feature and candidate generation through serving, experimentation, monitoring, and feedback loops. Collaboration with product, growth, data, platform, modeling, risk, and compliance teams is essential to translate ambiguous goals into measurable ML system designs.
Candidates should have over 12 years of experience in building and operating production software and ML systems for business-critical products. Deep expertise in intelligent systems such as ranking/retrieval, recommendations, search, personalization, growth and lifecycle ML, customer intelligence, propensity/churn/LTV, next-best-action, or model-derived risk signals is required. Strong production ML judgment across feature pipelines, model serving, experimentation, monitoring, feedback loops, online/offline consistency, and reliable signal interfaces is essential. Experience using AI-assisted engineering tools with appropriate verification, testing, and review for customer-impacting systems is also necessary.
