## About the role

6sense has agents and an MCP server in production today, used by real customers. This role takes them further by building more capable agents, strengthening the API and tool layer, and expanding an ecosystem that external agents, clients, and partners can connect to. You'll work across the full path from a customer's agent to 6sense data and actions, including APIs, tools, MCP, orchestration, context, evaluation, and security. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- Extend LangGraph orchestrators with typed state, conditional routing, subgraphs, checkpointing, durable execution, and human-in-the-loop workflows
- Select and implement routing, orchestrator-worker, plan-and-execute, reflection, and multi-agent handoff patterns based on business needs
- Run agents headless through API-first and MCP-first architectures across in-app, chat, workflow, and partner surfaces from a shared core
- Build and maintain reusable components for state management, memory, tool-calling, and agent-to-agent delegation with scoped permissions
- Evolve the APIs and tools agents use to access 6sense data and take action for both human and LLM consumers
- Optimize tool design for agent success, including naming, descriptions, schemas, response formats, error handling, and token efficiency
