Principal Software Engineer (unity, C#), Mobile Game Technology

Come join our team at Zynga making an impact across all of the company’s games - Mobile Game Tech (MGT)! . Lead the team by setting technical direction, crafting and providing technical solutions for our games. We’re looking for exceptional engineers with a strong passion for technology and hands-on experience in Unity and C#. The Principal Software Engineer will play a key role as part of the MGT Organization, focusing on advanced technology developments for building scalable end-to-end products which can be integrated into the various games. 

• Define, architect, & develop core engine components and build systems for iOS, Android, Kindle, and webGL using Unity and C#
• Drive end-to-end delivery of complex initiatives, from technical design and implementation to production rollout, monitoring, and ongoing operational ownership.
• Offer technical leadership by reviewing and guiding detailed compositions, ensuring alignment with Zynga’s long-term technical vision and standard methodologies.
• Collaborate multi-functionally with product, engineering, and operations teams to translate product and customer requirements into robust technical solutions.
• Establish and monitor engineering processes, quality metrics, and operational benchmarks to improve software delivery and system reliability.
• Guide incident response and postmortems, ensuring root-cause analysis and structural fixes rather than one-off patches.
• Mentor and coach engineers, fostering a culture of technical excellence, continuous learning, and knowledge sharing.
• While this is a client-focused engineering role, exposure to backend systems is beneficial. Familiarity with server-side concepts—or interest in learning them—is a strong plus, especially as our compliance solutions include both client and service components.

• 6+ years of software development experience
