Senior IoT / Embedded Linux Engineer
Posted about 2 months ago
About the Role
We are looking for a Senior IoT / Embedded Linux Engineer to join a small, high-impact hardware and firmware team. You will work closely with a Staff Hardware Engineer and Staff Firmware Engineer to bring connected embedded products from concept through production. This role bridges the gap between bare-metal firmware, Linux platform software, and cloud connectivity — and is ideal for someone who thrives at the intersection of hardware and software.
What You’ll Do
Design, develop, and maintain software for embedded Linux platforms (user space, drivers, and kernel customization).
Own the Linux BSP, including bootloader (U-Boot), device tree, and kernel configuration using Yocto or Buildroot.
Develop and maintain device drivers for peripherals (I²C, SPI, UART, USB, CAN, etc.).
Implement and maintain IoT connectivity stacks: MQTT, BLE, Wi-Fi, LoRa, and/or Zigbee.
Design and implement secure, reliable OTA update mechanisms.
Build and maintain the cloud/device communication layer (AWS IoT Core, Azure IoT Hub, or similar).
Collaborate with hardware engineers on board bring-up, schematic review, and hardware debug.
Contribute to firmware architecture decisions alongside the Staff Firmware Engineer.
Establish CI/CD pipelines and automated testing for embedded targets.
Mentor junior engineers and contribute to technical documentation.
Requirements
6+ years of embedded software development experience.
Deep proficiency in C and C++; Python for scripting and tooling.
Strong experience with embedded Linux (kernel, drivers, BSP) and build systems (Yocto and/or Buildroot).
Experience with ARM Cortex-A/M series SoCs and microcontrollers.
Hands-on experience with IoT communication protocols (MQTT, BLE, Wi-Fi, and/or LoRa).
Familiarity with cloud IoT platforms (AWS IoT Core, Azure IoT Hub, or GCP IoT).
Debugging skills with JTAG/SWD, GDB, logic analyzers, and oscilloscopes.
Experience with Git and collaborative development workflows.
Nice to Have
Experience with RTOS (FreeRTOS, Zephyr) alongside Linux — comfortable operating in both environments.
Experience with OTA update frameworks (SWUpdate, RAUC, or Mender).
Containerized edge computing experience (Docker or similar on resource-constrained Linux targets).
Background in a relevant product domain (industrial, meteorological, outdoor/ruggedized, or consumer IoT).
Ability to read schematics and PCB layouts; comfortable contributing to hardware bring-up alongside electrical engineers.
Familiarity with component datasheets, reference designs, and signal integrity concepts at the board level.
Experience with low-power design techniques — sleep modes, power gating, and energy profiling on embedded targets.
Exposure to ruggedized or outdoor hardware design considerations (thermal, vibration, ingress protection).
Experience writing and maintaining automated hardware-in-the-loop (HIL) or software-in-the-loop (SIL) test suites.
Familiarity with test fixture design or bench automation (Python-based instrument control, pytest-embedded, or similar).
Experience defining and executing validation plans for embedded devices: functional, stress, and regression testing.
Comfort reviewing or contributing to DFT (Design for Test) considerations during hardware reviews.
Basic familiarity with embedded security practices: secure boot, TLS/mTLS for device-to-cloud communication, and signed OTA packages.
Education
B.S. or M.S. in Electrical Engineering, Computer Engineering, or Computer Science — or equivalent demonstrated experience.
Benefits
You'll actually want to come in. Our Oak Lawn office isn't just a place to sit, it's where ideas move fast and culture stays strong. The whole team is here Monday through Friday, which means real collaboration, no chasing people down over Slack, and a genuinely fun place to spend your work days.
