Job description

Our client is building a next-generation financial services platform for high-net-worth clients — combining premium banking, rewards, and account services in one ecosystem. They're operating at serious scale (nine-figure ARR, multi-billion-dollar annual transaction volume) and remain fully profitable, with the growth trajectory of a company still early in its story.

This is a chance to join at a genuine inflection point, owning the backend systems — payments, rewards, account services, and partner integrations — that power a fast-growing, high-value customer base.

What you'll do

• Design and build backend services and APIs handling high-volume, high-stakes financial transactions
• Own full features end-to-end across payments, rewards, account services, and partner integrations
• Shape technical architecture as the platform scales
• Partner with frontend and mobile engineers on polished, full-stack features
• Raise the bar on reliability, performance, and observability across backend systems

What you bring

• 6+ years building backend or full-stack systems in production
• Strong experience with Python (Django preferred)
• Skill designing APIs, data models, and services on PostgreSQL and AWS

Nice to have

• Comfort in distributed, high-availability production environments
• A builder's mindset — you like owning things from concept to production
• Bachelor’s (or higher) degree in a Computer Science, Engineering or related field
