I’m hiring a full-stack Software Engineer for a small, high-velocity team building an AI-native platform used by major financial organisations. This team uses AI where it actually matters: helping structure and understand large volumes of financial data so users get instant, trustworthy insights.
The Role:
- You’ll work across a modern stack – React, TypeScript, Node, Postgres, AWS - taking features from idea → data model → polished UI → production.
- You’ll shape the architecture as the product scales, work closely with founders, and have a genuine say in how things get built.
You’ll Be a Great Fit If You:
- Have 5+ years’ experience building production-grade web apps with React + TypeScript
- Are comfortable across the stack - API design through to front-end polish
- Have experience with AWS or similar cloud infrastructure
- Care about ownership, quality, and impact
- Are curious about AI, automation, and modern code-assist tools (Cursor, Copilot, etc.)
- Move fast, test properly, and think like a product engineer
- Enjoy working in small, high-energy teams
Bonus Points For:
- Experience with Postgres, Prisma, GraphQL, Next.js
- Exposure to LangChain / LangGraph / AI-driven workflows
- Building something end-to-end yourself (side project, startup, OSS)
What You’ll Be Doing:
- Building features from scratch - schema to UI
- Working directly with founders on product decisions and trade-offs
- Refining architecture as the platform scales (multi-tenant + AI-heavy)
- Shipping to production fast and often
- Experimenting with AI tools to accelerate engineering
Why This Team?
- You’ll build complex, high-value product used by serious customers
- Join a small, elite group that genuinely cares about craft and velocity
- Be early enough that what you do actually moves the business
