Job Description

The Staff Machine Learning Engineer (player-coach) will design, build, test, and deploy production AI products and the underlying platform that enables agentic, LLM-powered capabilities on Google Cloud. The role combines applied machine learning with software engineering rigor, including support for stateful and transactional systems, and includes mentoring responsibilities.

Key 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 involve stateful and transactional (OLTP) systems, with focus on data modeling, concurrency, idempotency, reliability, observability, and testing.
Use classical ML, statistics, and experimentation when appropriate, including predictive modeling, statistical inference, hypothesis testing, and causal or incrementality measurement.
Build scalable automation tools for domains such as recommendation and personalization, conversational and customer experiences, and measurement and incrementality.
Produce design documents, maintain standards for clean code and documentation, and review designs and deliverables.
Mentor and develop engineers and scientists, including participation in early-career and student mentorship efforts.
Collaborate with engineering, product, and domain-expert teams on cross-functional automation, measurement, and modeling initiatives.
Participate in ELC’s diversity and inclusion agenda.

Required Qualifications

BS/BA in a quantitative or technical field (for example, Computer Science, Statistics, Mathematics, Physics, Engineering, Operations Research, Economics) or equivalent practical experience; a graduate degree is a plus.
5+ years of experience (or 3+ years 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, data-structures and algorithms, and a disciplined approach to testing. Experience building and operating production-grade services, including stateful/transactional systems and databases using SQL and/or NoSQL.
Production experience deploying and operating LLM-powered or agentic systems (examples: retrieval-augmented generation, agents and tool use, structured outputs, evaluation, safety) or a strong production ML background with a clear interest in transitioning into this space.
Experience deploying and operating systems on a major cloud platform, with Google Cloud as a plus, and sound data-processing practices at scale.
Experience using agentic/AI-assisted development tools, or a strong willingness to adopt them with judgment to protect quality.
A track record of mentorship, continuous learning mindset, bias for simplicity, and collaborative shared-ownership working style.
