Founding Software Engineer Location: London/onsite
The Mission
We are building the Agentic Operating System for Consultants.
The $1 trillion consulting industry is powered by some of the world’s brightest minds, yet they remain trapped in manual, inefficient workflows - spreadsheet orchestration, slide-deck assembly, and fragmented data synthesis. We are moving the industry from "human-plus-tools" to autonomous agency.
Backed by a seed round from Cherry Ventures, Blue Lion, and the founders of QuantumBlack, our cap table includes angels from OpenAI, McKinsey, BCG, and Apple. We have the capital, the network, and the domain expertise - now seeking further engineering support to get there faster.
The ChallengeAs one of our first engineers, you aren't just "writing code" - you are defining the technical DNA of the company. You will:
- Build Beyond the Chatbot: Design multi-step agentic workflows that move past simple RAG into reliable, enterprise-grade inference.
- Architect for Scale & Privacy: Build systems that can handle the rigorous data security requirements of Tier-1 financial and consulting firms.
- Own the Stack: Make foundational decisions on everything from our LLM orchestration layer to our deployment infrastructure.
- Interface with the Best: Work directly with technical & non-technical stakeholders across clients & advisory teams (OpenAI/McKinsey vets) to translate elite consulting tradecraft into code.
- You are a Product Engineer: You don’t need a 20-page PRD. You can take a vague user pain point from a design partner and ship a functional prototype by Friday.
- You have "Velocity as a Habit": You believe that in a seed-stage startup, speed is the only unfair advantage. You prefer shipping a 90% solution today over a perfect one next month.
- You are "T-Shaped": You are deeply technical in Python/Typescript and LLM frameworks (PydanticAI, LangGraph, etc.), but you also care about UI polish and user ergonomics.
- You have High Agency: When you hit a wall with an undocumented API or a hallucinating model, you find a way around it, over it, or through it.
- Languages: Python, TypeScript
- AI/Data: Pydantic / LLM Frameworks, LiteLLM, ElasticSearch
- Infra: AWS, Terraform, PostgreSQL
- Frontend: React / Tailwind
- Real Ownership: Significant founding-level equity. You will own a meaningful piece of the company you are building.
- Elite Peer Group: Join a team that has lived this problem at the highest levels of global consulting and AI research.
- High Trust / Low Bureaucracy: We value clarity of thought and bias to action. No middle management, no pointless meetings - just building.
