Senior Test Engineer; Firmware

Requirements

• A strong background in electronics; you are comfortable reading schematics and understanding the electrical constraints of embedded systems
• Proven experience in firmware development or low-level testing (C/C++), with a firm grasp of RTOS, interrupt handling, and memory management
• Expert-level proficiency in Python or similar languages for building scalable, automated test suites
• Comprehensive knowledge of serial and networked communication (UART, SPI, I2C, TCP/IP, and RS-485)
• The ability to see the "big picture" of a product ecosystem and the discipline to build a validation culture that balances speed with unshakeable reliability
• 7+ years of experience in firmware development, embedded systems engineering, or firmware validation, with at least 3 years in a lead or principal capacity
• Bachelor’s Degree in Electrical Engineering, Computer Engineering, Computer Science, or a related technical field (Master’s preferred)
• Expert-level proficiency in Python for developing complex, scalable test automation frameworks from scratch
• Deep understanding of C/C++ and the ability to read and critique production-level firmware, including RTOS-based architectures and interrupt-driven logic
• Hands-on experience with hardware lab equipment, including Oscilloscopes, Logic Analyzers, and Digital Multimeters for low-level signal analysis and troubleshooting
• Advanced knowledge of wired and wireless interfaces, specifically RS-485, UART, I2C, SPI, and TCP/IP networking
• Proven track record of implementing Hardware-in-the-Loop (HIL) testing
• Bachelor’s Degree
• 7+ years of firmware or embedded development

• As a test automation expert at Avigilon Alta, you will be the technical authority responsible for the validation strategy of our next-generation access control ecosystem. This role requires a deep understanding of how embedded systems interact with the physical world and the cloud. You will bridge the gap between electronics design, firmware development, and world-class test automation
• Design and lead the execution of comprehensive test strategies that cover the "hardware-to-cloud" journey, ensuring our readers and controllers are secure, performant, and resilient
• Develop sophisticated, hardware-in-the-loop (HIL) automation frameworks that exercise firmware at the driver, middle-ware, and application layers
• Utilize a broad understanding of electronics to debug complex issues using oscilloscopes, logic analyzers, and protocol sniffers
• Validate and stress-test a variety of communication protocols including RS-485, Ethernet/IP, BLE, NFC, and UWB
• Ensure robust device connectivity and security by testing network stacks, TLS/X.509 certificate handling, and data integrity across various deployment environments
• Mentor junior engineers and collaborate directly with Hardware and Software teams to implement "testability" into the product design phase (DFT/DFM)
