Job Title: Founding Engineer


Salary: £80K - £150K + Equity


Company Description: Aglide - YC S23 browser automation platform for enterprise security


Job Description:

Join a high-caliber team of four building a mission-critical browser automation engine for global enterprises. You will develop an on-device agent that autonomously manages sensitive workflows in applications lacking APIs. This role offers high ownership, direct customer collaboration, and the chance to invent the playbook for secure, browser-based identity and access management.


Location: London, UK


Why this role is remarkable:

  • Work on a novel "browser-using agent" platform trusted by decacorn financial services and public insurance companies to secure their most mission-critical workflows
  • Join a small, elite engineering culture of Imperial and Cambridge alumni with backgrounds at TikTok, operating with high autonomy and zero bureaucracy
  • Exceptional growth potential with founding-team equity and opportunities for frequent travel or relocation between the London and San Francisco offices


What you will do:

  • Develop and scale the core web-automation engine and on-device Electron environment to reliably perform complex tasks across macOS, Windows, and Linux
  • Build an intuitive workflow builder that allows non-technical enterprise users to configure autonomous automations for any web-based application
  • Design and implement end-to-end encrypted infrastructure to ensure the highest level of security for sensitive customer data and credentials


The ideal candidate:

  • 1+ years of production software experience with a proven track record of shipping robust, user-facing features in a fast-paced environment
  • Strong systems thinking and debugging skills, particularly with TypeScript, Postgres, and web automation tools like Puppeteer or Selenium
  • A high-ownership mindset with the desire to meet customers, diagnose complex problems, and ship production-ready solutions within a single week


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.

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.
