Role overview

Join LEC AI as an AI Founding Engineer to build Bishop, a foundation model for structured data, and Donnie, an agentic orchestration layer. You will write production code daily, making high-stakes architectural decisions that power diverse applications across energy trading, sports markets, and risk pricing, while leading a small, elite engineering team.

LEC AI is the technology arm of the London Export Corporation, a group with 74 years of trading history, now building a proprietary ecosystem of foundation models and agentic platforms to power a portfolio of specialized AI product companies.

What you will do

  • Develop and ship production-ready code for Bishop’s training pipelines or Donnie’s multi-agent memory architecture every week.
  • Architect the model serving infrastructure and data pipelines that handle real-world operational signals, prices, and time-series data.
  • Lead and mentor a small, high-performance engineering team while working directly with the Group CEO on technical strategy.

Who this is a fit for

  • Approximately 8 years of experience building production systems at elite AI labs like DeepMind or OpenAI, or top-tier quantitative trading firms like Citadel.
  • Deep technical expertise in foundation model fine-tuning, multi-agent orchestration, or low-latency distributed systems with a strong academic background from a leading institution.
  • A builder mindset with recent hands-on experience; you are an exceptional engineer who prefers shipping code over sitting in management meetings.

Why this role is remarkable

  • You will build foundation models (Bishop) and agentic systems (Donnie) from the ground up, moving beyond generic LLMs into high-value structured data.
  • Backed by a 74-year trading legacy, LEC AI combines the agility of a startup with deep capital reserves and a compounding moat of proprietary training data.
  • Choose your impact: either scale the core platform infrastructure or take ownership as the technical lead for a new product company within the ecosystem.
