Nexl is the fast-growing LegalTech startup on a mission to elevate the business of law.

Our platform is purpose-built for law firms, and brings together CRM, collaboration, and client intelligence in one solution — empowering lawyers, marketers, and BD teams to deepen relationships, accelerate growth, and win more high-value work.

We’re backed by top global VCs, recognised as one of Australia’s fastest-growing tech companies, and expanding rapidly across APAC, the US, LATAM, and Europe, and we’re only just getting started. 

We’re looking for a Senior Backend Engineer to join our growing Product & Engineering team, working within one of our cross-functional squads to scale the core services and architecture that power our platform.

This is a high-impact role where you’ll take ownership of backend execution, bring technical depth, and deliver reliable systems that make a difference for our users. Each squad has ownership of parts of our platform, and you’ll collaborate closely with product managers, frontend engineers, and other backend specialists to deliver end-to-end solutions.

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

• Strong collaboration skills across product and engineering functions.
• Passion for building scalable, maintainable systems.
