Senior / Staff Applied ML Engineer - AI / ML Evaluation & Simulation

San Francisco Bay Area, California, United States

Description

We're looking for a pragmatic engineer who thrives at the intersection of machine learning and software development — capable of building robust, scalable systems that support evaluation and development of advanced AI capabilities, including large language models and agentic behaviors.

A successful candidate is comfortable navigating ML, systems, and product domains. You bring strong software engineering fundamentals, experience building and maintaining end-to-end pipelines, and a practical understanding of how to evaluate AI systems in real-world contexts. You're curious about how LLMs behave in interactive or agentic settings, thoughtful about evaluation design, and eager to build tools that improve visibility and trust in AI. Above all, you enjoy collaborating across disciplines and bringing structure to complex, evolving problems.

Responsibilities

• Design and implement systems that simulate user-like interactions and workflows
• Build tools and infrastructure to generate, manage, and analyze evaluation data
• Develop scalable pipelines to extract structured insights from simulation outputs
• Collaborate with scientists and engineers to instrument and assess model performance
• Engineer reusable, testable components for experimentation and evaluation workflows
• Help define and operationalize success metrics aligned with product and research goals
