About ELLO

At ELLO, we're reinventing home security. Our AI-powered cameras don't just watch—they converse, contextualize, and bring foresight to every home. We're a small, passionate team building a product that changes how people interact with security devices.

We're looking for a seasoned Embedded Firmware Engineer who has shipped IoT products at scale, preferably on AWS, and thrives in fast-paced startup environments.

What You'll Do

  • Design, develop, and maintain embedded firmware for ELLO's next-gen security cameras.
  • Work with ARM-based MCUs, SoCs, and camera modules (low-level drivers, RTOS, Linux).
  • Implement and optimize wireless connectivity (Wi-Fi, BLE, Matter optional).
  • Build reliable OTA update mechanisms and device provisioning flows.
  • Integrate with cloud services (AWS IoT Core, Greengrass, or similar) for secure device-to-cloud communication.
  • Collaborate with hardware, CV/AI, and mobile teams to bring features from prototype to mass production.
  • Debug, profile, and optimize for performance, power efficiency, and security.
  • Support manufacturing and field deployment with diagnostic tools and firmware testing.

What We're Looking For

  • 5+ years of experience in embedded firmware development for consumer hardware or IoT products.
  • Strong skills in C/C++, with exposure to Python or shell scripting.
  • Hands-on experience with RTOS (FreeRTOS, Zephyr, etc.) and Linux-based firmware.
  • Proven track record building firmware that shipped in high-volume IoT/consumer electronics products.
  • Experience with AWS IoT (Core, Greengrass, Device Shadows, OTA jobs) strongly preferred.
  • Familiar with camera, video, or sensor integration.
  • Solid understanding of security protocols (TLS, device authentication, key management).
  • Familiarity with DFU, OTA, and factory provisioning workflows.
  • Bonus: knowledge of computer vision hardware pipelines or edge AI accelerators.

What You'll Get

  • A chance to shape ELLO's core product at the ground floor.
  • Work closely with founders and a passionate, experienced team.
  • Hybrid working environment (office Tue–Thu, flexible otherwise).
  • Competitive salary + potential equity/phantom shares.
  • Travel opportunities.
  • A culture of autonomy, trust, and building products that matter.
