About the role

Meticulous's mission is to make the world's code safe, performant and reliable.

We're starting with a tool to catch JavaScript regressions in web applications with zero-effort from developers.

How it works: Insert a single line of JavaScript onto your site, and we record thousands of real user sessions. We then replay these sessions on new code to automatically catch bugs before they hit production. You can watch a 60-second demo at

Catching JavaScript regressions is just the start. There is an entire category of products to build on top of replay. This ranges from automatic UI previews to revealing the performance impact of frontend code.

We are a London-based YC company. We are hiring an onsite (ideally a few days per week) founding engineer to join our team of two. We just raised $4m, and are backed by some of the best founders and technical leaders in Silicon Valley, including Guillermo Rauch (founder Vercel, author next.js), Jason Warner (CTO GitHub), Scott Belsky (CPO Adobe), Calvin French-Owen (founder Segment), Jared Friedman (YC partner and former CTO of Scribd) and a bunch of other incredible folks.

We want to change the way the world develops software, and influence software approaches for decades to come.

We are hiring our #2 founding engineer.

You will have autonomy in building out this technology, but here are a few problems you might work on:

  • Build a distributed system to concurrently replay thousands of sessions, such that a developer gets a result in seconds.
  • Speed up the replay of sessions in a way that retains determinism.
  • Derive algorithms to detect sessions that cover differing code paths and edge cases, and ignore sessions that are too similar.
  • Help build out a team of world-class, highly collaborative, software engineers.

As #2 engineer, you get to shape the company, and build the culture and technology from the ground up.

What we look for:

In a sentence: Technically brilliant, delightful to work with, combined with a self-awareness and strong desire to improve.

You should have experience with TypeScript or JavaScript. However, we are more interested in raw technical brilliance than experience with any particular language or technology. You have a deep love for software engineering. Maybe you enjoy programming books like Clean Code, Designing Data Intensive Applications, Pragmatic Programmer etc. or enjoy hacking on interesting side projects. You value transparency and candid feedback, and are driven by a strong desire to become the best engineer you can be.

Why you should join Meticulous

What you get:

Compensation: We want outrageously talented individuals. This means we offer commensurately outrageous equity grants. The equity grant will be 2% or greater with employee-friendly terms (10 year exercise window on options).

Learning: You will be given the space and time to up-level yourself as an engineer in terms of conferences, reading, or whatever you think will be most valuable. We will also set you up with mentorship, if you desire it, from top engineering leaders (folks running 100-engineer organizations at the world's leading tech companies).
