Job Description

Coris is building the AI-first trust and operations layer for global commerce. We partner with leading platforms, marketplaces, payment providers, and banks to transform how business onboarding, monitoring, and lifecycle decisions are made - using AI on the ground to drive faster, smarter actions with less friction.

Job Responsibility

  • Build and own Python/Django services that sit at the heart of Risk Decisioning and Execution
  • Model complex fraud/risk data in Postgres
  • write queries and aggregations that scale to billions of records
  • Build, operate, and enhance data ingestion pipelines from Stripe, Adyen, and other payment processors - as well as systems of record like Salesforce and Zendesk - handling near real-time volume
  • Integrate with poorly documented, inconsistent, and sometimes ancient APIs from legacy payment processors and platforms
  • Build feature engineering pipelines that extract signals
  • Implement customer-facing features like AI chat interfaces and graph visualizations
  • Analyze, diagnose, and fix UI latency and performance bottlenecks

Requirements

  • 1+ years building production systems in Python/Django with Postgres
  • Experience building frontend applications with React.js and Next.js
  • An AI-native way of working
  • A genuine willingness to do the unglamorous integration work
  • Very high energy and high agency
  • An experimental but practical mindset
  • A keen sense of information architecture and data presentation

Nice to have

  • Internship or early-career experience at a fast-scaling fintech or infra company (e.g., Stripe, Plaid, Brex, Adyen)
  • Familiarity with payment infrastructure, merchant underwriting, or risk tooling
  • Hands-on experience fine-tuning or optimizing LLMs/SLMs, ideally in fraud, anomaly detection, or adversarial domains
  • Experience working closely with product or design in an early-stage team
