Software Engineering Talent for Startups | Founder at 🖤💚Bounce Digital🖤💚

Title: Senior Software Engineer

Company Sector: Fintech (SaaS)

Tech: TypeScript, Node, React, Next, GraphQL, AWS

WFH / Hybrid: 2-3 days in office (Bank)

I’m hiring a full-stack Software Engineer for a small, high‑velocity team building an AI‑native platform used by major financial organisations.

Think: complex data, real users, real impact — but built with the speed and energy of a lean startup.

This team uses AI where it actually matters: helping structure and understand large volumes of financial data so users get instant, trustworthy insights.

If you enjoy tight build loops, meaningful ownership, and shipping at pace (not endless planning), you’ll like this.

The Role

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
