Duties & Responsibilities Position Detail Our team develops optical test and measurement equipment for telecommunications lab and manufacturing use. We are hiring a full-stack software and systems engineer to own the software for our industrial microscopy inspection appliance and its companion PC application, from microcontroller firmware to the Windows user application.
You will write the low-level embedded interfaces for motion, illumination and sensing on Atmel microcontrollers, build the USB video pipeline, develop the image analysis algorithms that judge inspection results, and deliver the Windows GUI and REST API that operators and factory automation systems use every day. The ideal candidate has supported a product through its full life cycle: concept, research, development and new product introduction.
Role / Responsibilities Designs, develops, troubleshoots and debugs software programs for enhancements and recent products.
Develops software and tools in support of design, infrastructure and technology platforms, including operating systems, compilers, routers, networks, utilities, databases,



cloud-based and Internet-related tools.
Determines hardware compatibility and/or influences hardware design.
Participate in the new product development team to specify, model, simulate, test and verify imaging and optical inspection systems and products
Contribute to system architecture and software requirements across firmware, PC software and the appliance
Develop embedded firmware on Atmel (AVR/SAM), arduino microcontrollers, plus serial/USB communication with the host PC
Build and optimize the USB video (UVC/DirectShow/Media Foundation) acquisition and processing pipeline for live and captured microscope images
Design, implement and validate image analysis algorithms for automated inspection, measurement and pass/fail grading
Develop the Windows GUI application in C++/C#/.NET/Qt with live video, results display, configuration and reporting
Design and maintain a REST API for integration with factory automation, test stations and data systems
Develop, test, debug and maintain software in C/C++/C3 and .NET under Windows (Linux a plus)
Collaborate through the full product lifecycle: requirements, prototyping, system integration, production support and customer feedback
Prepare technical documentation such as user manuals, interface specifications and test procedures
Work as part of an Agile software team and contribute to continuous department improvement
Required Qualifications Bachelor's or Master's degree in Computer Science,



Computer/Electrical/Systems Engineering, Mathematics or a related field
5+ years of professional software development experience in C/C++/C#
industry experience in imaging, machine vision or inspection applications
Demonstrated experience delivering products that span embedded firmware and a PC application
Required Capabilities Strong C/C++C# skills, including embedded C on resource-constrained microcontrollers (Atmel/Microchip AVR or SAM) and low-level peripheral interfacing (UART, SPI, I2C, ADC, timers, USB)
USB video experience: UVC cameras, DirectShow or Media Foundation, frame capture, buffering and real-time display
REST API design and implementation, including JSON, HTTP services and integration with automation systems
Solid knowledge of classical image processing theory and its application: focus and sharpness metrics, segmentation, edge/feature detection, calibration and measurement
Familiarity with imaging tools and libraries such as OpenCV, NumPy/SciPy, OpenGL or CUDA
Ability to debug across the whole stack using oscilloscopes, logic analyzers, protocol analyzers and software debuggers
Windows application development with .NET (C++,C#, WPF or WinForms),Qt, Microsoft Visual Studio and WinAPI, including native/managed interop
Excellent problem-solving skills and attention to detail
Excellent verbal and written communication skills
A good team player who works well in a collaborative environment
Preferred Qualifications Experience with digital microscopy, fiber-optic inspection or related optical inspection technologies
Python for algorithm prototyping, test automation and tooling
Knowledge of machine learning applied to image analysis, such as defect classif
