Not Disclosed

Company Description

Telemachus is a high-growth London startup that has scaled from zero to $15M in annualized revenue in just 11 months by rebuilding companies from the ground up using AI and minimal headcount.

Job Description

You will design and build the "machine" that creates and operates these companies. This involves architecting AI systems, automating complex commercial processes, and developing internal products that allow tiny teams to do the work of hundreds. You'll own technical problems end-to-end, moving seamlessly between abstract reasoning and production-grade implementation.

Location

London, UK

Why this role is remarkable

• Join one of the fastest-growing UK startups, reaching $15M ARR in less than a year with an incredibly small, elite team.
• Work directly with founders to solve ambiguous, high-impact problems across AI, distributed systems, and organizational machinery.
• High degree of autonomy and ownership; there are no product managers or platform layers between you and the real-world commercial outcomes.

What You Will Do

• Build AI systems capable of understanding and acting upon distributed information across emails, databases, and external software platforms.
• Design and implement the data models and infrastructure required to launch and scale new business units rapidly and reliably.
• Take full ownership of technical solutions, from understanding commercial requirements to deploying and observing systems in production.

The ideal candidate

• Exceptional technical builder with experience as a CTO or founding engineer, or a generalist with a background from places like Jane Street.
• Proven ability to solve complex, poorly specified problems by building substantial systems from scratch rather than just contributing to existing ones.
• Strong commercial judgment and the ability to choose the right engineering problems to solve to drive meaningful business growth.

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.
