WHAT YOU'LL DO

• Design and build robust, scalable APIs and backend services, then consume them in a typed, well-structured frontend.
• Build the interfaces that make AI usable for lawyers: streaming responses, long-running jobs, document-heavy workflows.
• Optimize performance across the stack — query performance on SQL, NoSQL and Vector stores; rendering, loading and responsiveness on the client.
• Work closely with product and design to turn ambiguous problems into shipped features.
• Uphold engineering standards through code reviews, testing, and CI/CD best practices.

• Production experience with Django or FastAPI, and with React (Next.js is a plus).
• Comfort with modern frontend fundamentals: component architecture, state management, accessibility, performance.
• Familiarity with cloud platforms (AWS, GCP, or Azure) and infrastructure fundamentals.
• Experience with modern databases — relational, document-based, or vector (a plus).
• Strong understanding of Git workflows, API design, and software engineering principles.
• Experience or genuine interest in ML/NLP and LLM integrations is a significant plus.
