About The Position

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.

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
Legal authorization to work in the U.S. indefinitely is required.

Responsibilities

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).
