Fullstack Software Engineer, ADK

AI-native role building agentic products and evals; works with agent frameworks, LLMs, and AI coding tools. About the Role Join Pelico as a founding Fullstack Software Engineer to build an agentic platform that connects factory data to AI agents, shipping end-to-end features from orchestration backend to React console and hardening durable runtime for real customers in manufacturing. Job Description Role Pelico is hiring a founding Fullstack Software Engineer to build an agentic platform used by large manufacturers. You will ship end-to-end agent capabilities, harden durable runtime execution, and build a trustworthy React console for real-time agent interactions and approvals. Key Responsibilities Implement end-to-end features from tools/MCP and orchestration backend through to the React console, delivering production-ready functionality for customers. Harden runtime behavior: durable execution, retries, scheduling, and human-in-the-loop approvals for agent actions with real consequences. Build and expand evaluation harnesses (scenario evaluations, LLM-as-judge) to detect regressions in agent behavior before release. Implement real-time streaming UIs that surface agent events, tool calls, and approvals reliably. Define and maintain frontend/backend contracts, write specs other engineers build against, and establish reusable patterns and craft standards. Requirements Proven track record shipping software; experience full-stack across a Python backend and a React frontend, or the ability to get there quickly. Strong engineering rigor with non-deterministic systems: specify and evaluate before shipping, own production behavior, and follow issues into production. AI-native mindset: familiarity with agent frameworks, tools, and evaluation practices; comfortable using AI coding tools. Comfortable working in fast-moving, ambiguous environments and iterating on evolving best practices. Nice-to-have Direct experience with agent/AI products (MCPs, agent frameworks, evals). Experience with durable workflow engines (e.g., Temporal). Experience building streaming UIs and strong observability practices (e.g., OpenTelemetry). Familiarity with spec-driven development, multi-tenant SaaS, or domain experience in aerospace/defense/discrete manufacturing.
