Senior/Staff Software Engineer, Experience

Pinecone is the trusted AI knowledge company. Its platform—including Database, Nexus, and Marketplace products—powers accurate, fast, and cost-effective AI applications for more than 10,000 customers and 1M developers worldwide.

The Experience team owns Pinecone's API, clients, authentication, revenue, and observability systems, redesigning them for a world where AI agents are first-class users alongside humans. This is a wide-scope role: you'll own things end-to-end from backend architecture to API design to SDK and web surfaces, working closely with product, design, and other engineering teams.

• Pioneer agent experience: shape how AI agents interact with Pinecone, designing interfaces, protocols (MCP), and tooling.
• Ship end-to-end experiences across API, SDK, CLI, and web, from the HTTP layer to the UI.
• Build systems that multiply team output: design AI-powered workflows, automated quality gates, and high-leverage platform capabilities.
• Set the standard for AI-assisted development on the team using tools like Claude Code, Cursor, or similar.
• Collaborate with product, design, and engineering to identify user and agent needs.
• Build observable, auditable systems with monitoring, alerting, and verification mechanisms.

• At least 4 years of software engineering experience.
• A bias toward automation and leverage.
• Hands-on experience shipping with AI coding tools (Claude Code, Cursor, Copilot, or similar).
• 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.

• Experience building or consuming MCP servers, or designing APIs explicitly for agent use cases.
• Familiarity with agentic frameworks and emerging patterns around tool use, orchestration, and agent-to-agent communication.
• Strong familiarity with a compiled language like Rust, Go, or Java.
• Experience with large-scale open-source projects.
• Experience developing database or query engine SDKs.

• Comprehensive health coverage including medical, dental, vision, and mental health resources.
• 401(k) Plan.
• Equity award.
• Flexible time off.
• Paid parental leave.
• Annual Company Retreat.
• WFH Equipment Stipend.
