About Lynx System Developers

Lynx System Developers is the world leader in photo-finish timing technology, with our FinishLynx system being used at major athletic competitions globally and providing precision timing to the thousandth of a second.

The Role

We're looking for a software developer to join our small, focused team working on FinishLynx 2.0 - a ground-up modernization of our photo-finish timing system. You'll work on both the C++ server (timing logic, camera control, image processing) and the C# cross-platform client (Avalonia UI).

This is a unique opportunity to work on specialized, real-world software where precision matters - our systems time races to the thousandth of a second.

What You'll Do

• Develop and maintain the C++ server handling camera communication, image streaming, and timing logic

• Build cross-platform UI features using C# and Avalonia

• Implement and test binary network protocols (TCP/UDP)

• Integrate with specialized hardware (EtherLynx cameras, timing sensors, scoreboards)

• Collaborate on architecture decisions for a modern, maintainable codebase

Required Skills

Programming Languages

• C++ (Modern C++17) - Strong proficiency required

• C# / .NET - Working knowledge required

Technical Skills

• Cross-platform development experience (Windows, macOS, Linux)

• Network programming (TCP/UDP sockets, binary protocols)

• Understanding of threading, synchronization, and real-time constraints

• Experience with CMake or similar build systems

• Git version control and CI/CD workflows (GitHub Actions)

• Strong testing practices (unit tests, integration tests)

Soft Skills

• Ability to work independently in a small team

• Clear communication and documentation skills

• Comfort working with legacy codebases and modernization projects

• Attention to detail (precision timing requires precision coding)

Preferred Qualifications

• Experience with desktop UI frameworks (Avalonia, WPF, Qt, wxWidgets)

• MVVM architecture patterns

• Hardware integration experience (serial protocols, cameras, sensors)

• Image processing or computer vision background

• Experience with real-time or embedded systems

• Sports timing or event management software experience

Tech Stack

Server C++17, CMake, POSIX/Win32

Client C#, .NET 8.0, Avalonia UI

Protocols Custom binary (TCP/UDP), EtherLynx camera protocol

Build/CI CMake, GitHub Actions

Testing CTest (C++), xUnit (C#)
