Job Specifications
Build the AI-powered drafting platform reinventing professional services.
Revax is building a new class of software for advisory firms. Today, accountants, tax advisors, and consultants spend countless hours drafting and re-drafting work, trapped by fragmented knowledge and manual workflows. We’re changing that - turning firms’ own expertise into intelligent, auditable AI-powered systems.
We’re a fast-moving, well-funded startup backed by leading angels. You’ll work directly with the founders to shape core product surfaces, scale our LangGraph-based backend, and build the AI-native experiences used by major advisory firms. This is a high-ownership role where your work will ship fast, be used immediately, and meaningfully shape the company.
What You’ll Actually Do
Build - design & ship (60%)
Build clean, responsive Next.js/React interfaces for our drafting and review workflows.
Develop and scale Python/LangGraph/FastAPI services powering multi-agent RAG pipelines.
Model and integrate knowledge-graph–driven search and retrieval flows (Vector databases, Neo4j).
Write well-tested, well-structured code that is production-ready from day one.
Scale & operate - own what you build (25%)
Deploy services on GCP (Cloud Run / GKE) and integrate with Supabase and self-managed databases.
Work with Docker, CI/CD (GitHub Actions).
Collaborate - product, design, (15%)
Shape specs with founders, define APIs with data/ML, and tune user experience.
Influence architecture, documentation, and our internal engineering culture.
What We’re Looking For
Essential
Undergraduate CS degree from a leading institution.
Skills in Next.js/React/TypeScript + Python backend.
Knowledge of API design, and modern system architecture.
High initiative, high energy - you take ownership, ship quickly, and care about outcomes.
Working knowledge of LangGraph and agentic systems.
You naturally use modern AI coding tools (Cursor, Claude Code, etc.).
Desirable
Experience with FastAPI, RAG, vector search, or knowledge graphs.
Project experience working on agentic AI products.
An interest in tax/accounting/professional-services workflows and a curiosity to learn.
Package
£30k salary pro-rata. Select interns will be offered a generous full-time package.
Hybrid – with a strong preference of working in office.
High trust, high autonomy, low bureaucracy.
