Responsibilities:
Firmware Architecture and Development: Design, implement, and maintain low-latency C/C++ firmware for microcontrollers (ARM Cortex-M) powering GSM/LTE communicators and alarm panels.
Communications and Protocols: Develop and optimize driver stacks (UART, SPI, I2C), cellular communications (GSM/LTE), and protocol handlers for reliable bi-directional alarm signaling.
System Reliability and Security: Implement diagnostics, watchdog/recovery mechanisms, logging, and security practices to ensure maximum uptime and power efficiency.
Hardware Integration and Bring-Up: Collaborate with hardware teams on schematic reviews, board bring-up, signal integrity, and design-for-manufacture (DFM).
Software and Cloud Integration: Support OTA firmware updates, device provisioning, and backend/cloud API interfaces alongside the software team.

Cellular and Peripherals: Proven experience with cellular modems (2G/3G/4G/LTE), AT command sets, and peripheral buses (UART, SPI, I2C, ADC, DMA).
Tools and Debugging: Proficiency with Git, JTAG/SWD debuggers, logic analyzers, oscilloscopes, and CI/CD pipelines for embedded systems.
Problem Solving: Track record of deploying production-grade firmware and debugging complex, intermittent field issues.
Education: Bachelor’s degree in Electronic/Electrical Engineering, Computer Engineering, Computer Science, or equivalent practical experience.
Desirable / Advantageous Skills
Experience in security, telemetry, IoT, or industrial automation sectors.
Familiarity with alarm signaling protocols (e.g., Contact ID, SIA).
Experience with OTA update architectures and device management platforms.
Knowledge of low-power design and battery-backed power management techniques.
Familiarity with ICASA regulatory compliance for radio equipment.
Scripting capability (Python) for automated testing and internal tooling.
Benefits:
Competitive salary based on experience (salary can potentially be more based on experience/skills)
