Job Description - Software Engineer at well-funded AI collaboration startup

This is a job that Jill, our AI Recruiter, is recruiting for on behalf of one of our customers.

She will pick the best candidates from Jack's network.

The next step is to speak to Jack.

Software Engineer

Company Description: Well-funded AI collaboration startup

Job Description:
You will build end-to-end features for a cutting-edge platform using AI and behavioral science to transform team coordination. Working directly with founders from Oxford and MIT, you will shape core architecture and develop agentic AI tools. This role offers a unique opportunity to join an elite team before public launch.

Location: London, UK

Why this role is remarkable:

  • Join an elite founding team of Oxford and MIT scientists building the next evolution of human-machine communication.

  • Benefit from a fully-expensed three-month accelerator residency in San Francisco to kickstart your journey.

  • Secure significant early-stage equity in a company backed by one of the world's most prestigious VC firms.

What you will do:

  • Build and own end-to-end features across a modern stack including React, Node.js, and TypeScript.

  • Architect scalable and secure systems as the product moves from prototype to production-grade software.

  • Collaborate with product and design to push the frontier of agentic AI and intuitive collaboration tools.

The ideal candidate:

  • Holds 1–3 years of professional full-stack experience with strong expertise in back-end development and PostgreSQL.

  • Possesses a "builder" mindset, thriving in high-ambiguity environments and shipping clean, scalable code rapidly.

  • Demonstrates a deep curiosity for AI, behavioral science, or developing generational tools that change how people work.

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.

Next steps

Step 1. Visit our website.
Step 2. Click 'Talk to Jack'.
Step 3. Talk to Jack so he can understand your experience and ambitions.
Step 4. Jack will make sure Jill (the AI agent working for the company) considers you for this role.
Step 5. If Jill thinks you're a great fit and her client wants to meet you, they will make the introduction.
Step 6. If not, Jack will find you excellent alternatives. All for free.

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.
