Strong Windows Ecosystem Background

• 5+ years of experience working with Windows applications and desktop software distribution

• Strong understanding of installers, drivers, OS-level APIs, software packaging, and Windows platform integrations

• Experience across Win32, .NET, UWP, WebView2, PWAs, or similar desktop architectures

Commercial Software Distribution Experience

• Background working at companies that ship and distribute commercial software products

• Exposure to packaging, deployment, signing, Store submission, and operating system integration

• Experience only building internal business systems is not enough for this role

Prototyping & Troubleshooting Mindset

• Ability to independently reproduce issues, create sandbox environments, and build reference implementations

• Strong problem-solving skills across low-level platform issues and technical ambiguity

Strong Communication & Ownership

• Comfortable working directly with clients and senior engineers

• Able to explain technical tradeoffs clearly and drive solutions proactively
