Senior Software Engineer, Self-Serve Intelligence

Lyft • San Francisco, CA

10h • Hybrid

About The Position

At Lyft, our purpose is to serve and connect. We aim to achieve this by cultivating a work environment where all team members belong and have the opportunity to thrive. Every day, millions of riders and drivers depend on Lyft — and when something goes wrong, we want to make it right as fast as possible. The Self-Serve Intelligence team within Safety & Customer Care org is building the AI-powered systems that do exactly that: resolving rider and driver suboptimal experiences without agent involvement through intelligent solutions in AI Assist (e.g. AI Agents), automations, and self-serve workflows. We're building backend systems, APIs, and AI-powered products that fundamentally rethink how customers get help — combining robust engineering with GenAI to deliver reliable, scalable self-serve experiences. As a Senior Software Engineer on the Self-Serve Intelligence team, you will design, build, ship, and maintain backend services and AI-powered products (e.g. various AI Agents) that autonomously resolve customer suboptimal experiences. You'll own the full lifecycle — from system design and prototyping through production deployment and operational excellence — partnering with product, design, data science, and operations to deliver high-quality, reliable solutions at scale.

Requirements

• 5+ years of software engineering industry experience
• Strong backend engineering fundamentals — designing, building, and operating distributed systems and microservices in production
• Hands-on experience with LLMs, agentic workflows, or building AI Agents — we value depth of AI experience and treat it as a strong differentiator
• Track record of building, evaluating, and shipping GenAI or ML-powered products
• Experience defining API schemas and developing backend services in a microservices environment
• When facing an ambiguous problem or outside your expertise, you can quickly learn what you need to dig in, make sense of it, and start working toward a solution
• You're a great communicator who can advocate for your proposals while empathizing with your teammates' goals and priorities
• You have a history of going out of your way to help your fellow engineers be more productive

Nice To Haves
