Job Description

You will join as the third engineer at a Shoreditch-based startup revolutionizing the rental market.

• Direct impact on an AI-centric global marketplace powered by proprietary social conversation data from over 10,000 real interactions.
• Exceptional culture with an SF-style work ethic, including free meals, gym memberships, visa sponsorship, and relocation support.
  
  

What You Will Do

• Take full ownership of the tech stack using TypeScript, React, Next.js, and Nest.js to ship features across the web and iOS.
• Build the foundation of an AI-driven trust engine that surfaces hidden social overlaps to verify users globally.
• Collaborate directly with the founders in a Shoreditch-based environment to define the engineering culture and product roadmap.
  
  

The ideal candidate

• 3+ years of professional full-stack experience, ideally in a fast-paced startup environment with a front-end heavy bias.
• Strong technical foundation with a Computer Science or Software Engineering degree from a reputable university.
• A first-principles builder who thrives in ambiguity and is ready to tackle complex human trust problems through technology.
  
  

Who are Jack & Jill?

Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

And I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate.

How does this work?

• Jack's an AI agent for job searching and career coaching. He works for you.
• Jill is the AI recruiter working for the company. She recruits from Jack's network.
• If it's a match and the company wants to meet you, they'll make the intro. In the meantime, if you'd like, Jack will send you excellent alternatives.
  
  

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.
