Principal AI Engineer — Agent Swarms & Autonomous Systems

LEC AI is the artificial intelligence business within London Export Corporation, building AI systems that operate real companies with real revenue as the measure of success. The Principal AI Engineer will architect and personally build production-scale agent swarms, including coordination, memory, learning loops, sandboxed self-coding, expert agents, judgement systems, and governance controls. The role requires shipping production code and designing reliable, auditable, and safely self-extending autonomous systems.

Responsibilities:

• Swarm-scale multi-agent architecture: many specialist agents in structured squads and hierarchies — a full organisational structure of agent departments — coordinating over durable infrastructure with defined roles, handoffs, reconciliation and containment
• Sandboxed self-coding: environments where agents safely write, execute, test and rework their own code and tools — fully isolated, permission-gated, auditable, with every change versioned and reversible
• Expert agents modelled from real-world knowledge: turning the recorded thinking of genuine specialists — documents, transcripts, recordings, decisions — into agents whose knowledge lives in files the system reads, extends and rewrites as understanding improves, continuously refreshed by harvesting what those fields' best minds are saying now
• Self-extension under governance: mechanisms by which agents create, evaluate and improve other agents and their own instructions, with every change gated, versioned and reversible
• Judgement systems: panels of agents that assess work independently, debate with evidence, and produce calibrated verdicts that become training data
• The operational spine: cost governance, quota management, human approval gates at every boundary where the system touches the outside world
• The agents themselves, hands-on: this is not a role directing a team of engineers — you personally design and build the agents, with junior support if useful. The agents are the workforce; you are their architect and builder
