Software Development Engineer, Firmware Validation

Primary Duties & 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
