Senior Software Engineer, Experience Platform

Pinecone is the leading vector database for building accurate and performant AI applications at scale in production. The Senior Software Engineer will own end-to-end experiences across API, SDK, CLI, and web, while designing systems that multiply team output and collaborating with various teams to meet user needs. Responsibilities: Pioneer our agent experience. Shape how AI agents interact with Pinecone — designing interfaces, protocols (MCP), and tooling that make Pinecone the easiest and most capable platform for agentic workflows to build on; Ship end-to-end experiences across API, SDK, CLI, and web. You'll own the full surface, from the HTTP layer to the UI, and you'll make calls across all of it; Build systems that multiply team output. We care about what ships, not how many hours went into it. Design AI-powered workflows, automated quality gates, and high-leverage platform capabilities that let a small team move at a pace that would otherwise require 10x the headcount; Set the standard for AI-assisted development on the team. Use the best tools available — Claude Code, Cursor, or whatever works — and help establish patterns that make the whole team faster; Collaborate with product, design, and engineering to identify what users (and agents) actually need and build it at the right abstraction level, at the right time; Build observable, auditable systems with monitoring, alerting, and verification mechanisms — because in a high-velocity environment, you need systems that tell you when something's wrong Qualifications: At least 4 years of software engineering experience; A bias toward automation and leverage — you reach for systems and tooling before you reach for elbow grease; Hands-on experience shipping with AI coding tools (Claude Code, Cursor, Copilot, or similar) as a genuine part of your workflow; Proven ability to design and deliver versioned APIs, SDKs, or client libraries; Proficiency building web interfaces with React or similar; Experience with at least one major cloud provider (AWS, GCP, Azure); Strong intuition for what makes APIs easy for both humans and agents to use correctly Required Skills: Software Engineering, AI Coding Tools, API Design, Web Development, Cloud Provider Experience, Compiled Languages, Agentic Frameworks, Open-source Projects, Database SDK Development
