• Contribute to platform improvements and help establish engineering patterns, templates, and documentation.

YOU MUST HAVE:

• 4-6+ years of experience in software engineering with a focus on UX or mobile app development.
• Strong understanding of .NET, C# and networking.
• Strong skills in at least one framework (e.g. Xamarin/MAUI or Flutter, etc…) developing for both iOS and Android.
• Understanding of database design and utilization.
• Hands-on experience with product launch and go to market strategies.

WE VALUE

• Exposure to connected devices or IoT-related systems.
• Ability to traverse the entire software stack.
• Knowledge of HVAC, smart home, or industrial systems a plus.
• Experience working with Infrastructure-as-Code (e.g., Terraform), CI/CD and GitHub actions.
• A pragmatic mindset—balancing engineering excellence with speed and business impact.
• A strong sense of ownership and pride in shipping high-quality, maintainable systems.
