Job Description

The Experience Platform team is at the center of one of the most exciting transitions in software development history — the shift from human-driven to agent-driven product experiences. We own Pinecone's API, clients, authentication, revenue, and observability systems, and right now that means redesigning all of it for a world where AI agents are first-class users alongside humans.

Job Responsibility

  • Pioneer our agent experience
  • Ship end-to-end experiences across API, SDK, CLI, and web
  • Build systems that multiply team output
  • Set the standard for AI-assisted development on the team
  • 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

Requirements

  • 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) 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

Nice to have

  • Experience building or consuming MCP servers, or designing APIs explicitly for agent use cases
  • Familiarity with agentic frameworks and the 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

What we offer

  • 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
