Job Title: Founding Engineer
Salary: £75,000 - £95,000 + Equity
Company Description: Revgentic.com - VC-backed startup building real-time AI sales coaching.
Job Description:
Join as a founding engineer at an AI startup that raised $1.6M to transform sales performance. Working directly with the CTO, you will build and own core product features end-to-end. You'll tackle the technical challenges of real-time contextual guidance, shaping the architecture of a platform turning good reps into great ones.
Location: London, UK
Why this role is remarkable:
Rare 0-to-1 opportunity to own 1.5% equity in a high-growth startup backed by $1.6M from leading investors and industry-heavyweight advisors.
Build at the absolute frontier of AI, moving beyond simple wrappers to create real-time, contextual coaching tools that didn't exist a year ago.
Massive career trajectory with a clear path to becoming a CTO or Engineering Leader as the team scales around your early contributions.
What you will do:
Ship core features end-to-end across a React and NestJS stack, moving from initial concept to production experiments with high autonomy.
Design and implement foundational architectural decisions that will define how the platform scales as it moves toward Series A.
Act as a technical sparring partner to the CTO, translating weekly customer feedback into robust, production-ready code that solves validated pain points.
The ideal candidate:
At least 3+ years of full-stack engineering experience with a strong command of React, Node.js, and ideally NestJS or MongoDB.
Proven track record of high agency, such as founding a company, shipping a significant side project, or being an early hire at a startup.
AI-native workflow expertise, demonstrating proficiency with tools like Cursor, Claude Code, and concurrent agents to accelerate development cycles.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
