Founding AI Software Engineer

Salary

£40k-£80k + Equity

Company Description

VC-backed AI venture studio

Job Description

As the first engineering hire, you will build and launch multiple creator‑led SaaS products from 0 to 1. Using AI‑native development tools to achieve 10x shipping velocity, you’ll architect scalable foundations, collaborate with high‑reach content creators, and influence the technical direction of an entire portfolio of emerging startups.

Location

London, UK

Why this role is remarkable

• Ship multiple unique products per year rather than iterating on a single feature, gaining unparalleled career velocity and product‑market fit experience
• Secure a meaningful founding equity stake in a studio backed by top‑tier VCs, positioning you as a key stakeholder in every venture built
• Work at the cutting edge of AI‑native engineering, using LLMs and agents as core teammates to bypass boilerplate and solve complex architectural challenges

What you will do

• Build production‑ready full‑stack applications using React, Next.js, and Python, moving from prototype to pilot in days rather than weeks
• Architect reusable component libraries and multi‑agent systems that serve as the technical engine for a portfolio of creator‑led businesses
• Collaborate directly with world‑class content creators to translate audience needs into functional software features and debug user feedback in real‑time

The ideal candidate

• An AI‑native developer who treats tools like Cursor, GitHub Copilot, or v0 as essential pair‑programmers to maintain extreme shipping velocity
• A proven product builder with 0–4 years of experience who has successfully launched side projects, hackathon winners, or open‑source tools to real users
• A high‑agency engineer with full‑stack proficiency in TypeScript and Python who thrives in ambiguous, fast‑paced startup environments and takes extreme ownership
