About the Role
Machine Learning Engineers at Lyft operate in dynamic environments, building world-class transportation solutions. This role focuses on designing, building, and deploying ML systems across Lyft Business, impacting pricing, fraud detection, and AI systems. It's ideal for technically versatile individuals energized by variety and direct business impact.
Responsibilities
- Develop and deploy ML models across multiple problem domains, including dynamic pricing, marketplace optimization, fraud detection, and anomaly/behavior detection, in production environments serving millions of rides.
- Build and iterate on agentic AI systems (e.g., LLM-powered analytical agents) that automate decision-making and reduce operational overhead.
- Design and implement feature pipelines, model training workflows, and serving infrastructure using Lyft's ML platform.
- Partner with Data Scientists on the Algorithms and Decisions teams to take research prototypes from proof-of-concept to production at scale.
- Evaluate ML system performance against business KPIs, run experiments, and drive continuous model improvement.
- Identify new opportunities where ML can create leverage across Lyft Business verticals (Healthcare, Lyft Pass, Business Travel) and pitch solutions.
- Contribute to team engineering standards, including code quality, observability, documentation, and testing practices.
Requirements
- Experience with GenAI / LLM ecosystems — prompt engineering, RAG, agent frameworks (e.g., LangChain, LangGraph), or fine-tuning.
- Exposure to graph-based ML methods (graph neural networks, knowledge graphs, network analysis).
- Experience with pricing, marketplace, or fraud-related ML problems.
- Familiarity with cloud ML services (AWS SageMaker, Bedrock) or internal ML platforms.
- Track record of identifying and scoping ML projects independently, not just executing on pre-defined specs.
