• Strong knowledge in machine-to-machine communication, network setups, security, data transfer protocols, multi-threading, asynchronous programming, and network protocols such as TCP/IP, UDP, HTTP, and gRPC.
• Create SDKs and APIs for customers to interface with our semiconductor test systems, and package/distribute them as NuGet packages.
• Develop platform-agnostic and language-interoperable solutions for integration with Windows, Linux, and embedded systems.
• Work with SQL/NoSQL databases and optimize the data processing.
• Ensure libraries are well-documented, versioned, and optimized for performance and scalability.
• Work with Microsoft Azure for hosting, packaging, and distribution of client libraries.
• Collaborate with QA and test automation teams to develop robust unit, integration, and regression tests.
• Optimize for performance, memory usage, and cross-platform compatibility.
• Implement secure coding practices and maintain compliance with industry standards.
• Engage with product management and customer-facing teams to gather requirements and ensure usability.
• Support hybrid cloud and on-premises integration scenarios.
• Be willing to travel occasionally, including internationally (10%–20%).
