A pre-seed, founder-led startup is seeking a Founding Engineer to build the "Agentic Financial Ops" layer for the global fintech market. This stealth-mode venture is embedding autonomous AI agents directly into major B2B platforms—automating invoicing, bill pay, and payroll for SMBs. This is an opportunity to join at the ground floor of a company targeting a $100B market shift.
What you will build:
- The Engine: A white-label, API-first, multi-tenant system designed to embed cleanly and securely into partner ecosystems.
- The Intelligence: You aren’t just calling APIs; you are treating LLMs as infrastructure. You will build agentic workflows that handle complex financial operations autonomously.
- The Foundation: You will replace the founder’s initial "vibe-coded" prototype with a robust, production-ready architecture. You decide the stack; you set the engineering culture.
The Role:
- This is not a ticket-taking role at a stagnant SaaS. This is a Decide + Build + Own seat where you sit directly beside the founder.
- Zero to One: Take the product from MVP concept to Production.
- Full Ownership: Build the core platform end-to-end (Backend, APIs, Frontend).
- Architecture: Design for security, permissions, and scale from day one.
- Speed: Iterate fast with real customers. The goal is to launch the API in Q2.
The Profile:
- Mindset: Scrappy, high-growth, and product-minded. You care deeply about why a feature exists, not just how it’s built.
- Experience: A Senior Engineer (Backend-leaning or Full-stack) who has shipped early-stage products into production.
- Tech: Hands-on experience with LLMs & agentic workflows. You are pragmatic about tech choices that optimize for speed and correctness.
The Offer:
Salary £95k–£120k + Significant Founding Equity.
