Job summary

Pelico is building an agentic platform for manufacturers. You’ll be one of the founding engineers, writing code close to customers and factory data, spanning Python backend and React frontend. You’ll ship end-to-end agent capabilities, harden the runtime, and improve evals and observability while collaborating with a small, elite AI-native team.

Ownership from day one is expected. You’ll own features from design to production and influence the craft bar across the stack, impacting some of the

Qualifications

• Excellent engineer who ships, with real production code experience.
• Able to work full-stack across Python backend and React frontend.
• Able to spec and eval before shipping, and own what goes out including AI-assisted code.

Responsibilities

• Ship agent capabilities end to end from backend to React console.
• Harden the runtime with durable execution, retries, scheduling, and human-in-the-loop approvals.
• Make agents trustworthy by growing the eval harness and catching regressions.
• Build a console with real-time streaming of agent events, tool calls, and approvals.
• Write specs, keep contracts honest, and leave reusable patterns for the team.

Job description

About Pelico

Every 16 minutes, something disrupts how a factory runs. Supply chains don't fail from bad decisions, they fail from late ones. Pelico's platform already helps leading manufacturers anticipate and respond to blockers. Multiple AI agents are already deployed on top of the platform to drive outcomes everyday.

About Pelico

Every 16 minutes, something disrupts how a factory runs. Supply chains don't fail from bad decisions, they fail from late ones. Pelico's platform already helps leading manufacturers anticipate and respond to blockers. Multiple AI agents are already deployed on top of the platform to drive outcomes everyday.

About The Role

Companies have multiple founding moments and Pelico is going through a new one.

You would be one of the founding engineers of our new agentic platform, building alongside a small, super talented, high-bar team. This is a hands-on seat from day one: you write the code that manufacturers and their own AI teams build on, close to real customers and real factory data.

You benefit from company assets (data, events dependency graphs, simulation engine, next best action algorithms) and the reach that comes from Pelico running the operational data of multiple leading manufacturers.

What You'll Do

• Ship agent capabilities end to end. Build real features from the tool/MCP and orchestration backend through to the React console, live for users - not demos.
• Harden the runtime. Durable execution, retries, scheduling, and human-in-the-loop approvals on agent actions that carry real consequences.
• Make agents trustworthy. Grow the eval harness (scenario evals, LLM-as-judge) so we catch regressions in agent behavior before they ship.
• Build a console people believe. Real-time streaming of agent events, tool calls, and approvals - clear, fast, and reliable enough that a controller trusts it.
• Set a craft bar. Write specs others build against, keep the frontend/backend contract honest, and leave reusable patterns the team adopts.

About You

We care about how good you are and how far you can go, and we calibrate to the experience you bring. This seat is built for exceptional people - whether you are just out of a top program or already have a few years of serious building behind you.

• An excellent engineer who ships. You write excellent code and have built real things, full-stack across a Python backend and a React frontend - or you are clearly able to get there fast.
• Hungry and driven. You want a hard problem to own, not a comfortable seat, and you have the ceiling to grow into far more.
• Rigorous with non-deterministic systems. You spec and eval before shipping, trust evidence over vibes, and own what goes out - including AI-assisted code - following problems into production.
• AI-native and curious. You understand how agent frameworks, tools, and evals actually work under the hood, and you build with AI coding tools every day.
• Calm in fast-moving ambiguity. You stay effective on a stack where this quarter's best practice changes next quarter, turning uncertainty into a workable plan.

Nice to have

real AI/agent product experience (MCP, agent frameworks, evals); durable workflow engines (e.g. Temporal); streaming UIs; observability (OpenTelemetry); spec-driven development; multi-tenant SaaS, or aerospace/defense/discrete-manufacturing context.

Why Pelico

If You Want To Build Something Hard From The Ground Up, With Real Ownership From Day One, This Is The Seat.

What Comes With It

• A founding team and a real mandate. You help build Condor from its early days, with genuine ownership of what you ship and room to grow fast.
• The highest-stakes work you could take on. You build for some of the largest manufacturers, at the scale of their global operations, on a moat competitors cannot copy: we own both the factory simulation and the scoreboard that says whether an agent actually helped.
• A small, elite, AI-native team. Be challenged by strong peers, learn quickly, and ship fast.
• Competitive salary benchmarked to your market, plus health, dental, and vision coverage and a learning budget.
