Description

Nexl is the fast-growing LegalTech company on an ambitious mission to elevate the business of law.

We build an AI-driven CRM and growth intelligence platform that brings a firm's internal and external data together so lawyers, marketing, and business development can collaborate, spot opportunities, and grow revenue.

Recognised by the Financial Times, Deloitte, and the Australian Financial Review as one of the fastest-growing businesses, Nexl is trusted by 150+ firms globally.

We've closed a $23 million Series B led by Tidemark Capital, accelerating our mission to transform how law firms grow by uniting lawyers, marketing, and business development into a single growth engine.

Our Tech Stack:
Frontend: React & TypeScript
Backend: Ruby on Rails with GraphQL, and Python with WebSockets & Protobuf

  • Skilled in API design, database management, and backend performance optimisation.
  • Strong collaboration skills across product and engineering functions.
  • Passion for building scalable, maintainable systems.
