Lead .NET/C# Engineer

We’re looking for a Lead Engineer who can own system architecture end-to-end — from translating product/customer needs into scalable backend systems, to making architecture trade-offs, to guiding frontend integration. This is not just a coding role: you’ll be the technical decision-maker working directly with the founder to design and deliver systems that can scale with our growth. This is a great fit for someone who thrives in remote, high-autonomy environments. Responsibilities include driving architecture decisions for our client’s core platform, ensuring scalability, security, and performance. You'll partner with product and customers to translate requirements into technical designs and implementations. The role balances hands-on coding with setting technical direction and mentoring others. Contribute to and support the existing React front-end, C# .NET Function Apps, and other Azure resources, as needed.
