Job description

Position Summary

• Design, code, integrate, test, and debug game software for slot machines.
• Demonstrate a strong understanding of the platform hardware, libraries, and operating system.
• Provide input on game design and scheduling as it relates to software implementation.
• Effectively communicate technical requirements to team members.
• Collaborate with software quality assurance engineers to ensure regulatory compliance and timely product release.
• Cultivate, maintain, and disseminate internal systems knowledge while providing feedback on platform and tools implementation.
• Mentor junior engineers in related studios and throughout Game Development.
• Create or update documentation related to new features, interfaces, and usage.
• Contribute to in-house development toolset and engineering support.
• Maintain up-to-date knowledge on new programming methods and technologies.
• Use Claude Code and Cowork intentionally as part of daily engineering work - coding, debugging, test writing, and documentation.
• Apply healthy skepticism to AI-generated output: check for invented APIs or methods, subtly incorrect logic, and missed edge cases before work moves to review.
• Set the standard for how the team verifies AI-assisted work; help others recognize and work around common AI shortcomings rather than taking output at face value.
• Take a leading role evaluating and adopting agentic coding workflows as they mature, weighing fit against our regulatory constraints.
