Job summary

AssetWatch is seeking a Firmware Engineer to develop production embedded firmware while contributing to electrical design, hardware bring-up, validation, and product launch. This is a hands-on role across code, bench work, and field support for the AssetWatch hardware team.

You will design, debug, and maintain firmware and device communication, enabling robust OTA/FOTA updates and secure networking across BLE, Wi‑Fi, Ethernet, and cellular paths.

Qualifications

• Must be based in the Columbus, Ohio area and able to work from the office at least three days each week.
• Demonstrated experience developing, debugging, releasing, and sustaining production embedded firmware in C or C++.
• Practical electrical engineering experience, including reading schematics, reviewing PCB layouts, supporting board bring-up, and troubleshooting analog, digital, power, and embedded interface issues.
• Experience with network-connected devices, edge gateways, or hubs using technologies such as BLE, Wi‑Fi, Ethernet, cellular, TCP/IP, UDP, DNS, DHCP, TLS, MQTT, HTTP/HTTPS, or VPNs.
• Experience with embedded Linux and/or RTOS-based systems, device state machines, diagnostics, logging, fault handling, and common interfaces such as I2C, SPI, UART, or CAN.
• Hands-on proficiency with firmware and hardware debug tools, including oscilloscopes, logic analyzers, DMMs, debug probes, serial logs, packet captures, or equivalent equipment.
• Experience supporting product launches from prototype through qualification, manufacturing readiness, production ramp, and post-launch field support.
• Success in a multi-functional engineering role spanning firmware, hardware, test and validation, documentation, manufacturing support, and root-cause problem solving.
• Working knowledge of secure connected-device practices, including authentication, authorization, encrypted transport, credential handling, signed firmware, secure boot, or secure update flows.
• Experience with Git-based development, pull requests, code review, branching, release control, and clear technical documentation.
• Strong written and verbal communication, sound engineering judgment, and comfort working through ambiguous cross-disciplinary problems.
• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field - or equivalent practical experience.

Responsibilities

• Develop production embedded firmware in C/C++ for sensors, hubs, gateways, and related connected hardware.
• Design and debug features for device communication, scheduling, data collection, configuration, diagnostics, logging, and OTA/FOTA updates.
• Develop and troubleshoot connectivity across BLE, Wi-Fi, Ethernet, and cellular paths, including TCP/IP, DNS/DHCP, TLS, MQTT/HTTP, provisioning, reconnection, signal quality, and network diagnostics.
• Support embedded Linux and/or RTOS components, peripheral interfaces, and edge services that connect device firmware and hardware to backend/cloud systems.
• Contribute to schematic and PCB reviews, component selection, power and interface design, design-for-manufacture, and design-for-test decisions.
• Bring up and debug new hardware using oscilloscopes, logic analyzers, DMMs, power profilers, debug probes, serial logs, packet captures, and other lab tools.
• Develop and execute test plans; support fixtures, regression and hardware-in-the-loop testing, failure analysis, and environmental or compliance pre-screening.
• Own work across firmware, hardware, validation, documentation, manufacturing support, and field issue resolution while collaborating with electrical, mechanical, test, cloud, product, cybersecurity, support, and contract-manufacturing partners.
