In this role, you will architect secure, scalable, and resilient embedded software that bridges edge hardware with cloud infrastructure. You will work closely with hardware engineers, systems architects, and cloud teams from initial board bring-up through volume manufacturing and field deployment., * Firmware Architecture & Development: Design, code, and maintain production-grade C/C++ firmware for resource-constrained microcontrollers (ARM Cortex-M, ESP32, RISC-V, etc.). * IoT Connectivity & Protocols: Implement and optimize low-power wireless communication stacks, including Wi-Fi, BLE, Cellular (LTE-M/NB-IoT), Thread/Zigbee, and application protocols such as MQTT, CoAP, and HTTP/HTTPS. * Hardware Bring-Up & Driver Development: Write low-level device drivers for peripherals (I2C, SPI, UART, ADC, PWM, DMA, flash memory) and collaborate with hardware teams during board bring-up and debugging. * Power Optimization: Analyze and implement aggressive power management strategies (sleep modes, duty cycling, peripheral management) to maximize battery longevity for edge devices. * Security & OTA Updates: Implement hardware-root-of-trust security features (secure boot, TLS, cryptographic acceleration, key management) and robust over-the-air (OTA) firmware update mechanisms. * System Integration & Testing: Utilize RTOS platforms (FreeRTOS, Zephyr, or embedded Linux) to write multithreaded applications; conduct hardware-in-the-loop (HIL) testing and automated regression testing. * Lifecycle & Manufacturing Support: Support factory test fixture development, diagnostic firmware creation, and mass production testing protocols. * Mentorship & Process: Drive code reviews, enforce coding standards (e.g., MISRA C), write technical documentation, and mentor junior and mid-level firmware engineers. ## Related Videos - [Code to Road in < 12 hours](https://www.wearedevelopers.com/videos/1082-code-to-road-in-12-hours) - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Unleashing the Full Potential of the Arm Architecture – Write Once, Deploy Anywhere](https://www.wearedevelopers.com/videos/940-unleashing-the-full-potential-of-the-arm-architecture-write-once-deploy-anywhere) - [Git for Code Reviews](https://www.wearedevelopers.com/videos/429-git-for-code-reviews) - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Stop Committing Your Secrets - GIt Hooks To The Rescue!](https://www.wearedevelopers.com/videos/573-stop-committing-your-secrets-git-hooks-to-the-rescue) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs)
