About The Position

We're seeking a Senior Embedded Engineer to work across our MCU-based edge sensors and embedded Linux–based platform. This is a hands-on role at the cutting edge of IoT and edge computing, within a company experiencing rapid growth. You'll own significant pieces of the embedded stack end to end — firmware, OS builds, connectivity, and OTA — and your work on remote access, updates, and cloud connectivity will be pivotal to our product reliability.

Requirements

7+ years of hands-on embedded software development
BS in Computer Science, Electrical or Computer Engineering, or a related field; embedded systems specialization preferred
Deep expertise in C/C++ across RTOS and embedded Linux environments
Hands-on experience with embedded Linux builds (Yocto or Debian-based), BSPs, and kernel or driver development
Experience with networking stacks and multi-interface connectivity, including failover and recovery behavior
Experience with OTA firmware update systems and cloud-IoT integration (AWS IoT Core, Azure, or equivalent)
Experience with low-power design for battery-operated devices
Strong communicator — able to translate technical decisions for non-technical stakeholders

Responsibilities

Own the design and implementation of significant components of the embedded software stack for our IoT gateway and edge devices
Participate in design and code reviews, and help uphold engineering standards across the embedded team
Work closely with hardware, firmware, QA, and cloud teams to integrate and debug across boundaries
Evaluate and recommend tools, frameworks, and technologies to support the roadmap
Design and develop firmware for our MCU-based edge sensors, including RTOS tasks, drivers, sensor integration, wireless stacks, and low-power design
Build and maintain embedded Linux OS images (Yocto or Debian-based), BSPs, kernel modules, and device drivers
Implement and maintain connectivity across Ethernet, Wi-Fi, LTE/4G, Wi-Fi HaLow, and PoE, including failover and recovery behavior
Integrate edge ML inference and cloud middleware (AWS IoT Core, MQTT, REST APIs)
Implement security features including secure boot, signed firmware, certificate management, and access control
Develop and maintain OTA firmware update flows, including rollback protection and staged rollout
Implement system health telemetry, watchdog, auto-recovery, and remote diagnostics
Develop and execute embedded test plans; contribute to CI/CD pipelines for firmware builds and validation
Perform peripheral bring-up, SoC driver integration, and RF/sensor validation
Profile and optimize performance across CPU, memory, I/O, storage, and network
