You will collaborate closely with Product, Design, Backend, QA, AppSec, and Platform partners to build secure, scalable, and delightful consumer-facing experiences.

    • Develop API-first, microservice-oriented systems that are modular, resilient, and independently deployable.
    • Build and maintain REST and/or GraphQL APIs consumed by frontend and mobile customers.
    • Implement transactional, audit-friendly workflows for gameplay, wallets, bonuses, and settlements.
    • Integrate with third-party systems (payments, KYC/identity, fraud, analytics).
  • Quality, Security, and Operations.
    • Work closely with QA/SDET partners to ensure strong automated and manual test coverage.
    • Collaborate with AppSec and compliance partners to meet PCI and security expectations.
    • Design systems with traceability, data integrity, and operational observability in mind.
    • Support production systems and participate in debugging and incident resolution.
Required Qualifications

  • 5+ years of professional software engineering experience with significant frontend and backend ownership.
  • Strong experience with React, Next.js, Tailwind, TypeScript, and Node.js.
  • Experience building and integrating REST or GraphQL APIs.
  • Solid database skills, especially in PostgreSQL.
