Crimson (YC X25) is hiring founding engineers in London
AI law startup wants a founding engineer in London — lawyers cheer, coders argue
TLDR: Crimson, a YC-backed AI for lawsuits, is hiring a founding engineer in London with £80–120k and equity. Comments erupted over AI replacing junior lawyers, office days, and pay vs risk, with fans hyped for faster cases and skeptics fretting about accuracy, accountability, and whether “Do you Bicep” is a requirement.
Crimson, a YC-backed AI platform for lawsuit battles, just dropped a “founding engineer” call in London, and the comments instantly turned into courtroom drama. Supporters called it “the end of soul‑crushing document review,” while skeptics shouted, objection!—worried about AI drafting pleadings and “hallucinating” facts at 3 a.m.
The pitch: work with top law firms, build tools that summarize testimony and find evidence “in seconds,” and own features end‑to‑end. Salary is £80–120k plus equity, 3 days a week near Bank. Tech folks zoomed in on the stack—Python, TypeScript, Azure, GitHub Actions, and “IaC (infrastructure as code) via Bicep”—and immediately memed: “Do you even Bicep, bro?”
Hot takes split the room. Some devs said this could actually fix messy litigation workflows and give junior lawyers their weekends back. Others warned: “When AI drafts submissions, who gets blamed in front of the judge?” There’s also a lively pay vs risk debate—“founding expectations at employee salary”—and a remote‑work tussle over the office requirement. One legal‑tech old‑timer dropped the reality check: law firms love speed but fear mistakes; trust, accuracy and security will make or break this. Meanwhile, everyone’s refreshing their inbox to see if the founders really reply within 24 hours.
