A well-funded fintech startup building the infrastructure that makes global payments and financial operations actually work at scale. The platform processes millions of transactions across 190+ jurisdictions - calculation, filing, remittance - at millisecond latency with zero downtime. Think of it as the layer that sits beneath the financial internet and keeps it honest.

They need a Senior Product Engineer to own and ship new product lines as they scale.

What you'll do

• Own end-to-end development of new product areas: payment flows, filing infrastructure, data pipelines
• Ship mission-critical features used by enterprise customers within your first weeks
• Work directly with customers to improve and optimise key platform components
• Set direction in areas you own - small team, no playbook
• Mentor engineers in components you've built

 

About you

• Strong Python engineer, comfortable owning a backend codebase and data pipeline end to end
• Experience with high-volume transaction data or business-critical financial systems
• Very strong attention to detail: near-correct isn't good enough at this scale
• Built at early-stage before: ambiguity is motivating, not draining
• Full-stack capable - not afraid to jump into React when needed

 

Nice to have

• Django or Python ORM
• Fintech, payments, or high-stakes data domains
• Familiarity with agentic or LLM-integrated systems
