Founding Product Engineer
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 ICP and a standardised, scalable product.
This hire is one of the earliest engineering 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 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
