ALERT:
Unity has received reports of scams where individuals purporting to be Unity HR representatives conduct bogus employment interviews via email or text, and then request payment as a condition for receiving an offer of employment. Please be aware that Unity does not conduct interviews by email or text, and will never request payment as a condition for applying for a position or receiving an offer of employment.

These scam operators may also ask for your personal information (name, address, birthdate, social security number, etc.) which you should not provide to them. If you have been a target of such a scam, you should report it by contacting the U.S. Federal Trade Commission (see this FTC posting for further details) the office of your state Attorney General, or the government agency responsible for investigating matters such as this where you reside.

Unity’s scale and versatility serve millions of developers building for hundreds of target configurations, genres, and platforms. As our technology stack has grown more powerful and complex, the need for real‑world validation of innovations prior to broad release has become critical. The Production Verification (PV) Program connects our product teams with strategic partner game productions and ensures that every major advancement, optimization, or feature we build is proven in production, before it reaches our broader Unity ecosystem.

The Production Verification team supports Unity's reliability and performance across real‑world customer projects.

• Help to migrate customer code into internal systems
• Coordinate game collection refreshes when developers make significant updates to their projects
• Support Product teams with profiling and benchmarking PV games when they lack bandwidth
• Provide technical expertise and customer insights to inform Unity's product development

• Strong proficiency with Unity Editor, Unity Engine architecture, and experience upgrading projects across Unity versions
• C# Skillset:
