Job Summary:
Coherent Corp. is a global leader in lasers and engineered materials, seeking a Software Development Engineer for Firmware Validation. The role involves bridging hardware and software through the development of a Python framework for firmware validation, designing high-level software abstractions, and maintaining code quality and documentation.
Responsibilities:
• Bridge the gap between hardware and software by developing a modular python framework to communicate with low-level hardware using protocol-level communication interfaces (e.g., USB, I2C, UART) which enables our software application to interact with hardware for efficient firmware validation and seamless hardware-software integration.
• Design and implement high-level software abstractions for low-level hardware communication protocols, ensuring minimal latency and preserving the performance characteristics of time-sensitive I2C transactions.
• Develop reusable test scripts and modules to validate firmware behavior, execute regression suites, support new product introduction (NPI) testing and hardware bring-up.
• Implement structured logging and reporting, generating outputs in formats like JSON, CSV, or HTML for traceability and auditability.
• Maintain high code quality, detailed documentation for Application architecture, testing procedures, validation results and reusable components for future scalability
• Integrate with databases or dashboards for test result visualization and analytics.
Qualifications:
Required:
• Bachelor’s degree in computer engineering, Electrical Engineering, Computer Science or a related field.
• Strong programming skills in Python, C++ and C# with experience in building modular, scalable codebases.
• Deep understanding of hardware communication protocols: I2C, SPI, UART, USB, MDIO, etc.
• Experience developing test frameworks or automation tools for firmware or embedded hardware.
• Familiarity with tools like smbus2, pyserial, python-periphery, pyvisa, or similar.
• Ability to debug using lab tools (oscilloscopes, logic analyzers, power meters).
• Comfortable working in a Linux environment, with git, scripting, and CI fundamentals.
• Strong verbal and written communication skills for documentation and cross-functional work.
• Sitting for extended periods while working on a computer or conducting meetings.
• Use of hands and fingers for typing, writing, and handling documents.
• Occasional lifting of objects or materials up to 20 pounds for administrative tasks.
• Ability to communicate verbally and in writing.

• Depending on location, this position may be responsible for the execution and maintenance of the ISO 9000, 9001, 14001 and/or other applicable standards that may apply to the relevant roles and responsibilities within the Quality Management System and Environmental Management System.
Preferred:
• Master’s degree.
• 1-2 years of industry experience.
• Prior experience in optical transceiver validation, CMIS protocol, or related hardware.
• Exposure to IronPython or C#/Python interop in WPF environments, experience integrating with test databases or visualization tools.
