• Monitor and resolve security vulnerabilities, manage secrets (SSM/GitHub Secrets), and ensure best practices.
• Work with databases and ORM tools for data modeling and migrations.
• Build responsive and accessible UI components using the shared design system.
• Write comprehensive unit, integration, and E2E tests, and ensure CI/CD pipelines (GitHub Actions) remain green.
• Design ingestion, transformation, and publishing flows across 3rd party services integration, so data lands in the appropriate entities.
• Hands-on work with DSP APIs (Deliveroo, Uber Eats, Grubhub) or kiosk and POS systems
• Maintain and improve the modular architecture of the monorepo. Ensure clean separation of concerns.

• You write readable, maintainable, and well-documented code.
• Short iterations, small PRs, and frequent deployments.
• Fluency in AWS (ECS Fargate, S3, RDS, SSM, CloudWatch) as well as Terraform, and GitHub Actions so you can debug deployments end to end.
• Exposure to security scanning and compliance pipelines (Trivy, GitHub Advanced Security, etc.) and experience triaging CVEs before production deploys.

• You use AI to move faster, never at the cost of quality.
• Strong proficiency in TypeScript, Node.js, and React, experience with NestJS (Modules, Guards, Interceptors, Dependency Injection).
• Containerization: Solid understanding of Docker and Docker Compose for local development and deployment.
• Experience building production-grade AI agents: creating robust evals, implementing guardrails, and architecting RAG pipelines
• Solid testing and reliability habits spanning Jest unit or functional suites, contract tests, and browser automation (Playwright or Puppeteer) plus observability tools such as Sentry, New Relic, and Prometheus.
• You enjoy tackling complex architectural challenges in a distributed system.
• Experience ingesting marketplace or delivery-service data sets and normalizing them into unified financial or operational models.
