About our client

An emerging "Native AI" enterprise operations firm is currently scaling its high-velocity engineering team to pioneer the field of Workflow Intelligence. Operating at the intersection of deep system integration and advanced machine learning, the company builds mission-critical infrastructure that provides organizations with unprecedented visibility into internal processes to optimize human capital and automate complex workstreams. As they approach a major global launch in early 2026, this engineering-heavy startup is seeking founding-level talent dedicated to clean architecture and solving non-trivial technical challenges within a fast-paced, high-ownership environment.

About the Role

Our Windows app is critical to capturing performance data and enabling insights across enterprise environments. We’re looking for an experienced Windows app developer to take ownership of development, stability, and deployment — working alongside Denis to scale the platform.

What you'll do

• Lead Windows app development with a focus on performance, maintainability, and cross-environment stability.

• Profile, debug, and optimize for speed, memory usage, and reliability.

• Build for managed and restricted enterprise environments using MDM tools and deployment best practices.

• 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

Bonus points

• Experience with cross-platform or Electron-based apps.

• Understanding of Django or other backend frameworks and API design.

• 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 the 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.
