Bachelor's degree in Electrical Engineering, Computer Engineering, or a related discipline, plus five or more years developing embedded hardware and firmware products from concept through production.
Strong embedded C/C++ experience with microcontroller development in bare-metal and/or RTOS environments.
Strong analog and digital circuit design experience, including schematic capture and PCB development or review.
Hands-on board bring-up, debugging, validation, and root-cause analysis using appropriate lab equipment.
Experience implementing and debugging common embedded communication interfaces such as SPI, I²C, UART, RS-232/RS-485, CAN, Ethernet, or USB.
Demonstrated experience taking physical embedded products from prototype through validation and production release.
Strong analytical, troubleshooting, and root-cause analysis skills, with a practical and hands-on approach to solving complex problems.
Clear technical communication and documentation; collaborative, curious, and accountable, with ownership and follow-through for secure, reliable, production-ready results.

Nice To Haves

Experience developing embedded Linux-based systems; Yocto experience is particularly valuable.
Experience with wireless technologies such as Bluetooth Low Energy (BLE), Wi-Fi, or NFC.
Experience implementing secure boot and embedded cybersecurity practices.
Experience with electronic access control, security, IoT, or other connected-device products.
Experience supporting regulatory certification and compliance activities such as FCC, CE, UL, EMC/EMI, RoHS, or REACH.
Python experience for test automation, diagnostics, or engineering tools.
Experience working with Docker containers and embedded web server development.
Experience with Matter, Thread, Z-Wave, or Zigbee.
Knowledge of NIST, FIPS, or ISO cybersecurity frameworks and standards.
Familiarity with Git, Azure DevOps, GitHub, Jira, Confluence, or CI/CD development environments.

Responsibilities

Lead embedded hardware platforms for access control, credential readers, door controllers, wireless and sensing devices, and connected security products.
Define system architectures and select processors, memory, wireless modules, sensors, power components, communication interfaces, security features, and peripherals.
Create schematics and guide PCB layout and reviews for signal and power integrity, grounding and shielding, EMI/EMC mitigation, and thermal performance.
Conduct board bring-up, validation, troubleshooting, and root-cause analysis; support product qualification and manufacturing transfer.
Develop and maintain embedded C/C++ firmware, including drivers, hardware abstraction layers, diagnostics, bootloaders, device-management functions, and application code.
Implement bare-metal and RTOS-based solutions, including task scheduling, interrupts, inter-process communication, timers, and resource management.
Develop secure firmware architectures and apply embedded cybersecurity best practices, secure coding, and appropriate cryptographic controls.
Integrate wired and wireless connections to cloud, mobile, and enterprise systems; debug, optimize, validate, and sustain firmware throughout the product lifecycle.
Contribute across concept, architecture, prototyping, verification, certification, production launch, and sustaining engineering.
Partner across teams to ensure integration, manufacturability, quality, and supportability; maintain specifications, test plans, manufacturing documentation, and engineering change records.
Support customer-issue investigations and field problem resolution using disciplined analysis and clear technical communication.
Support FCC, CE, UL, EMC/EMI, RoHS, REACH, and related compliance activities; evaluate emerging technologies, standards, tools, and architectures.
