Job summary

Reddit is seeking a Senior Staff Machine Learning Engineer to define and accelerate agentic AI-driven modeling, improving model quality and velocity. You’ll lead modeling loop efforts, guide teams, and apply AI-assisted systems like Claude and Cursor to boost rigor and outcomes.

You will collaborate with product, data science, ML infrastructure, and engineering teams to shape technical direction, ensure guardrails, and deliver high-impact ML programs across the organization.

Qualifications

• 9+ years of experience in ML engineering, applied ML, or a related field with production impact.
• Senior Staff-level technical leadership and a record of influencing direction across teams.
• Deep modeling expertise and fundamentals in data, objectives, architectures, optimization, evaluation, and experimentation.
• Concrete examples of using agentic AI or AI coding tools to improve ML outcomes—not just faster code generation.
• Ability to design guardrails and evaluations that make autonomous or semi-autonomous workflows trustworthy.
• Strong coding ability in Python and fluency with modern ML frameworks and data tooling.
• Clear, concise communication and a collaborative leadership style.

Responsibilities

• Develop advanced ML models and the agentic workflows that help teams design, train, evaluate, and improve them.
• Use tools such as Claude, Cursor, and comparable AI-assisted development systems to investigate model behavior, generate and test hypotheses, automate repetitive analysis, and improve code and experiments.
• Build reliable loops for data and label analysis, feature and embedding development, architecture comparison, hyperparameter optimization, error analysis, and experiment readouts.
• Design evaluation harnesses that measure both model outcomes and agent/workflow quality, including correctness, reproducibility, regressions, cost, and latency.
• Partner with product, data science, ML infrastructure, and engineering teams to connect modeling improvements to user and business outcomes.
• Set technical direction across teams, mentor engineers, and raise the bar for modeling rigor and AI-assisted engineering.
