Founding Engineer (City of London)

As Technical Co Founder / Founding Engineer, you’ll lead engineering as we productise the role of an Buy Side M&A — turning scattered calls, decks, and spreadsheets into intelligent, persistent agent workflows that get smarter over time.

This isn’t just prompt-chaining. You’ll design and own:

• Autonomous agents that can reason, plan, and execute over multi-session lifecycles

• Secure memory containers that allow context to persist for months

• AI-first interfaces that combine chat, file handling, enrichment tools, and decision logic

This is a ground-floor opportunity to define both the architecture and the product DNA.

What you'll be building:

1. Agent Infrastructure

• Build robust agent flows using Claude + n8n (multi-turn, tool-using, context-aware)
• Solve failure points in prompt injection, webhook logic, and payload parsing
• Orchestrate tool use across workflows (e.g. buy-side sourcing, sell-side preparation)

2. Memory, Privacy & Data Isolation

• Architect persistent memory for long-form agent interactions (vector store + DB hybrid)
• Create private containers per user/project (multi-tenant security by design)
• Ensure session-based recall of chats, uploads, enrichment, and decisions

3. UX, Chat Interface & Tools

• Optimise and polish our Claude-powered chat interface (React)
• Embed file upload, parsing, and real-time enrichment tools within conversation flows
• Ensure performance even with large documents and asynchronous processing

4. Productising Expert Logic

• Convert real-world consulting flows into structured agent logic (if/but, intent-routing)
• Implement onboarding flows to auto-configure agent behaviour by user type (buyer, seller, advisor)
• Guide architecture choices for future modular agent deployment

Stack

• AI : Claude API (Anthropic), Exa (search/enrichment)
• Workflow Orchestration : n8n (webhooks, branching, logic)
• Memory & DB : PostgreSQL, Redis, Pinecone
• Front-End : React, Tailwind
• Infra : Replit, Make.com (light no-code layer), AWS/GCP optional

Requirements:

Required

• 7+ years in full-stack development (strong back-end bias)

Experience with:

• LLM APIs and context/state management (Claude, OpenAI, etc)
• Workflow engines like n8n or Make
• Designing secure multi-tenant SaaS products
• Scaling DBs and infra across real-time chat and long-term memory

Nice-to-Have

• Built or scaled an agent-native product (LangChain, Replit AI, etc)
• Familiar with M&A, private equity, or high-value B2B workflows
• Strong product sense—can simplify complexity without dumbing things down
