Senior Client Platform Engineer

Role Summary:

The Senior Client Platform Engineer provides technical leadership across shared client platforms supporting High 5 Casino and Lucky Bits Vegas. This role is responsible for translating product requirements and design specifications into scalable, maintainable client-side implementations while ensuring architectural consistency, release stability, and cross-platform continuity across web and mobile environments.

In addition to providing technical oversight, this role remains actively involved in hands-on development. The engineer directly implements client-side features, enhances existing platform functionality, and contributes production code across multiple systems, including modern web platforms and legacy client applications. This hands-on involvement ensures that architectural decisions remain grounded in practical implementation while maintaining code quality and performance standards.

The position plays a critical role in safeguarding authentication systems, monetization flows, and shared platform infrastructure that directly impact product stability, user experience, and revenue continuity. Acting as a primary technical quality gate for client engineering output, the role ensures high standards for code maintainability, readability, and functional integrity across multiple codebases.
