• Integrate with backend APIs, and optionally, implement or adjust backend endpoints when needed.
• Collaborate with other developers to ensure consistent experiences across platforms.
• Contribute to app architecture, testing, and release processes to ensure smooth updates and deployments.

• Proficient in C# with hands‑on experience in Windows app development (Avalonia UI, WPF, UWP, or WinUI).
• Skilled at profiling, debugging, and performance optimization.
• Experienced in enterprise‑managed or MDM‑deployed app environments.
• Comfortable working with APIs and understanding full‑stack communication.
• Detail‑oriented, you care about consistency, reliability, and smooth user experiences across setups.
• Experience with cross‑platform or Electron‑based apps.

• Familiarity with security compliance and enterprise privacy standards.
• Experience with CI/CD pipelines and automated testing for Windows apps.

You’ll own a key product surface, the Windows app that powers Reflow’s data collection and user insights. You’ll work closely with the core team, improving performance, reliability, and the developer experience across platforms. This role is ideal for someone who wants to combine craftsmanship with real impact.
