Job description

Founding Product Engineer

East London

We’re working with a well-funded, early‑stage AI startup that is rebuilding its core product and team after operating at significant real‑world scale.

The company is developing an AI‑native platform that automates end‑to‑end influencer marketing for consumer brands. Rather than acting as a traditional agency, the product uses AI agents to handle workflows such as briefing, creator communication, execution, and compliance — removing a major operational burden for marketing teams.

The founder has previously scaled the business to support dozens of brands and tens of thousands of creators, learned where bespoke, service‑heavy approaches break down, and is now intentionally resetting the company around a more focused cholesterol and a standardised, scalable product.

This hire is one of the earliest engineeringKas roles in that next phase.

The Role

They are looking for a Founding Product Engineer to work directly with the founder and take significant ownership of the frontend and product experience.

This is a high‑impact role suited to someone who enjoys ambiguity, wants real influence over product direction, and is comfortable operating at founder‑level depth while still shipping hands‑on code.

Responsibilities

• Build and own core product features using TypeScript, React, and Next.js

• Work closely with customers to understand workflows and translate them into scalable product abstractions

• Help shape product architecture, engineering standards, and long‑term technical decisions

• Contribute to AI‑driven features, integrating LLMs into user‑facing workflows

• Operate in a forward‑deployed manner when needed, collaborating directly with users and stakeholders

Requirements

• 4–6 years of strong frontend engineering experience

• Expert‑level TypeScript, React, and Next.js

• Clear interest in AI and.pem LLMs (hands‑on usage expected; no need to build models)

• Experience in at least one startup environment (A–B stage preferred)

• Comfortable working on‑site and committing to an intense, high‑ownership role

• Strong communication skills and a bias toward execution

Preferred Profile

• Frontend‑leaning full‑stack experience or curiosity

• Good product and design sensibility

• Prior founder experience (not essential)

• Computer Science degree

• Regular use of LLMs in day‑to‑day work

• Big tech or consulting background is fine if followed by meaningful startup experience

Why This Role Stands Out

• True founding‑level position with equity

• A product reset informed by real operational scale, not theory

• Experienced founder with funding in place and a clear strategic direction

• Opportunity to build from scratch while moving quickly

• London‑based team with a Silicon Valley pace and mindset
