Job Description

The Staff Machine Learning Engineer (player-coach) will design, build, test, and deploy production agentic and LLM-powered AI products, along with the platform capabilities that support them. This role combines software-engineering rigor for stateful and transactional systems with practical classical ML and experimentation, operating primarily on Google Cloud.

Responsibilities

Design, build, test, and deploy production agentic and LLM-powered products end-to-end on Google Cloud, including the shared platform, tooling, and harnesses beneath them.
Apply strong software-engineering rigor to services that include stateful and transactional (OLTP) systems, with attention to data modeling, concurrency, idempotency, reliability, observability, and testing.
Use classical machine learning, statistics, and experimentation when appropriate, including predictive modeling, statistical inference, hypothesis testing, and causal or incrementality measurement.
Build scalable tools for automation across recommendation and personalization, conversational and customer experiences, and measurement and incrementality.
Write design documents, uphold standards for clean code and documentation, and review designs and deliverables produced by others.
Mentor and grow engineers and scientists, including support for early-career and student mentorship efforts.
Partner with engineering, product, and domain-expert teams on cross-functional automation, measurement, and modeling initiatives.
Participate in Estee Lauder’s diversity and inclusion agenda.

Requirements

BS/BA in a quantitative or technical field (examples include Computer Science, Statistics, Mathematics, Physics, Engineering, Operations Research, Economics) or equivalent practical experience; a graduate degree is a plus.
5+ years of experience (3+ with a graduate degree) across Software Engineering, Machine Learning, and/or Data Science.
Strong general software engineering in Python, including clean API and service design, proficiency with data structures and algorithms, and disciplined testing. Experience building and operating production-grade services, including stateful or transactional systems and databases (SQL and/or NoSQL).
Experience deploying and operating LLM-powered or agentic systems in production (such as retrieval-augmented generation, agents and tool use, structured outputs, evaluation, and safety) or a strong production-ML background with a clear interest in this work.
Experience deploying and operating systems on a major cloud platform, with scalable data-processing practices (Google Cloud is a plus).
Uses agentic or AI-assisted development tools, or is eager to adopt them with strong judgment about where they help and how to maintain quality.
A track record of mentorship, continuous learning mindset, bias for simplicity, and a collaborative shared-ownership approach.
