C# Socket Programming Developer

Job Title: C# Socket Programming Developer

Location: 5 days onsite, needing someone in houston

Sub Vending is fine

Job Summary:

We are seeking a skilled C# Socket Developer to develop high-performance networking application to communicate with remote I/O devices. The ideal candidate will have expertise in TCP/IP, UDP, Web Sockets, and multi-threaded programming in C#. The candidate will work on real-time communication systems, client-server applications, and network protocols.

Required :

Project Overview Connection to Hardware Device:
The application needs to connect to a hardware device, which will be provided by an external vendor. Data Handling: TCP will be used to fetch data, get package information, and process the data for internal software.

Key Responsibilities:

• Develop and maintain socket-based communication systems in C#.
• Implement TCP, UDP, and Web Sockets for real-time data transmission.
• Design multi-threaded applications ensuring efficient data processing.
• Optimize network latency and performance for high-throughput applications.
• Debug and troubleshoot network issues, connection failures, and data loss.
• Implement asynchronous programming and event-driven architecture.
• Ensure secure communication using encryption (SSL/TLS) and authentication mechanisms.
• Write unit tests, integration tests, and performance benchmarks for networking code.
• Collaborate with backend, frontend, and Dev Ops teams to ensure seamless application integration.

Required Skills &

Qualifications:

• 5+ years' experience using C++, C# and .NET Core/.NET Framework.

• Experience with  for TCP/UDP communication.

• Understanding of socket lifecycle (connect, send, receive, close).

• Expertise in multi-threading, parallel programming, and async programming.

• Knowledge of networking concepts (IP addressing, ports, protocols, firewalls).

• Familiarity with Web Sockets, Rabbit

MQ for real-time applications.

• Experience working with Windows Services, Linux sockets, or embedded systems (preferred).

• Knowledge of REST APIs and microservices architecture (plus).

• Bachelor's degree in Computer Science, Engineering, or a related field.
