Crimson is the AI platform for high-stakes litigation. We're working with top law firms in the UK and US to streamline how complex disputes are run. Our platform drafts pleadings and submissions, analyzes judgments and orders, summarizes transcripts and locates key evidence in seconds.
We're a team of three co-founders with deep technical and domain expertise. Our users are lawyers who trust us with their most sensitive case files. They care about security, accuracy, reliability and speed, and so do we.
We're looking for an exceptional full-stack engineer to join us as one of our first employees. You'll ship production code from day one and own major features end-to-end. That means talking to users, scoping the problem, building the solution and improving it over time.
What you'll do
Contribute to the entire stack, from cloud infrastructure to prompting to UX (Python backend, Next.js with TypeScript frontend, PostgreSQL, SOTA LLMs. Deployed to Azure via IaC (Bicep) with CI/CD pipelines powered by GitHub Actions)
Collaborate closely with users to understand how lawyers work and what they need
Architect and scale document ingestion and processing pipelines to power fast, accurate search and data extraction for large volumes of legal documents
Develop intelligent, multi-step agent workflows that can autonomously handle complex legal tasks - from surfacing key testimony across depositions to generating fact chronologies and auto-detecting inconsistencies in opposing counsel’s filings
Design and bring to life intuitive AI-native user experiences tailored to litigation workflows
Improve system performance, stability and observability as we scale
Help shape our engineering culture and team - from best practices to hiring and mentorship
