Meticulous (YC S21) Is Hiring to Eliminate E2E UI Tests
Hey HN!

I'm Gabriel, CEO and co-founder of Meticulous, https://meticulous.ai/?utm_source=hn.

Meticulous is a tool which creates and maintains a suite of e2e tests that exhaustively covers your web application - without any developer intervention whatsoever. We’ve also eliminated flaky tests (really!). No flakes. The tech behind this is fascinating.

Meticulous passively records sessions and uses these to generate a comprehensive test suite.

Our customers love the product and rely on meticulous.ai (https://meticulous.ai/?utm_source=hn) as the sole system for testing their frontend. Here’s what they say:

“Once you start using Meticulous, you won’t want to stop. It provides confidence without the effort of writing and maintaining tests. I love the tight feedback loop of seeing a visual confirmation of my changes, and any unwanted side effects.” - Joel, engineer at Patchwork Health

“Meticulous eliminated the need to write and maintain frontend tests across my engineering organization. One of the most exciting DevTools on the market today.” - Seth, CTO at Courier

We trust Meticulous to be the sole front-end testing system for our app. It has caught countless UI bugs and regressions without us having to write a single test. This coverage saves us time and gives us confidence to move quickly.” - Nick, engineer at WithPower

How does Meticulous work?

Insert a single line of JavaScript onto your site, and we record thousands of real user sessions. We then replay these sessions on head and base commits of PRs, take screenshots at key points, and diff those screenshots to catch regressions before they hit production. It catches logical, behavioral and visual issues. We employ novel techniques to eliminate flakes. You can watch a 60-second demo at https://meticulous.ai/?utm_source=hn

What’s our team like?

We are a London-based YC company. Our engineering team previously worked at Dropbox, Opendoor, Palantir, GitHub and Google, and have previously led 100+ engineer organizations at these companies. We 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.

Catching visual regressions is just the start. There is an entire category of products to build on top of replay. This ranges from catching exceptions to revealing the performance impact of frontend code.

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

We are seeding a London office and hiring an onsite founding engineer to join our team of six. We sponsor visas.

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 founding 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. We also want to make sure everyone is highly supportive of each other; we win as a team.

We're currently only looking to bring on folks with senior level skill sets and 5+ years of industry experience. You should have strong web fundamentals and 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 motivated by a strong desire to become the best engineer you can be.

You can read about our values here https://ruby-wish-a8f.notion.site/Mission-Values-979c32ec58e...

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).

You’ll get to work alongside some of the best engineers there are, break new ground solving truly novel CS problems and deliver something that transforms how software is built.
