Job description
About the Position
We are looking for a Low-Level Systems Engineer to join our team and develop firmware and systems software for our AI-driven pet care wearable. This role focuses on low-power design and connectivity, ensuring our product delivers reliable, intelligent insights for pet owners.
About Us
Our company is building the intelligence layer for modern pet care. We develop a premium, low-power connected wearable that tracks a dog’s location, activity, movement, sleep, and wellbeing, turning it into AI-driven insights. Our product combines on-device processing, multi-radio connectivity, and a cloud-native AWS platform to deliver real-time and historical insights reliably, for months on a single charge. We are an early-stage startup with a small team, fast decisions, and real ownership. The person we hire will help create and shape the technical foundations of the company as we scale.
Responsibilities
- Own the firmware and low-level software across the device, including RTOS/bare-metal application code, drivers, and board-support work on Nordic nRF (Zephyr) and Espressif ESP32 (ESP-IDF).
- Work close to the metal: memory management, concurrency, scheduling, interrupts, bootloaders, and robust, low-overhead system design on constrained hardware.
- Build a power-aware architecture: a state machine spanning standard, live, low-power standby, and Lost Dog modes, tuned for predictable, minimal power draw.
- Own multi-radio connectivity in software - cellular (LTE-M/NB-IoT), BLE, Wi-Fi, and GNSS - with resilient behavior on flaky, low-bandwidth links.
- Deliver device-to-cloud communication: MQTT and low-power UDP to our AWS IoT backend, secure device provisioning, and a reliable OTA update system.
- Build the on-device data path: sensor drivers, sensor fusion, and embedded (edge) ML pipelines for activity and behavior classification.
- Own device security: secure boot, provisioning, and encrypted communication.
- Partner closely with the electrical engineer on bring-up and hardware debug, and build the tooling, tests, and CI that keep firmware reliable at scale.
Requirements
-
Essential
- A strong low-level / systems software background: expert in C/C++, working close to hardware - drivers, RTOS or OS internals, memory, concurrency, and interrupts.
- Firmware experience on constrained microcontrollers (Arm Cortex-M) with an RTOS such as Zephyr or FreeRTOS - or a strong systems background with genuine embedded appetite and some hands-on exposure.
- Solid understanding of networking and protocols (TCP/UDP, MQTT), ideally over constrained or low-power links.
- Real awareness of low-power design - sleep states, duty cycling, and the software side of battery life.
- Strong debugging skills with JTAG/SWD, logic analyzers, and scopes - comfortable at the hardware/software boundary.
- Thrives in a startup: comfortable with ambiguity, shifting priorities, and owning outcomes end to end.
-
Nice to Have
- Direct experience with our exact stack - Nordic nRF Connect SDK / Zephyr and/or Espressif ESP-IDF.
- Experience with cellular IoT (LTE-M/NB-IoT), BLE, and GNSS integration.
- TinyML or embedded ML experience - running inference on-device for activity or motion classification.
- Secure boot, provisioning, and embedded security experience; bootloader and OTA design.
- Experience integrating devices with cloud IoT backends, especially AWS IoT Core / MQTT.
- Prior startup or founding-team experience, and any exposure to wearables, consumer IoT, or the pet space.
What We Offer
- Competitive compensation for a senior, foundational hire, including meaningful equity.
- Real room to grow into a technical leadership role as the company scales.
- Location-flexible and remote-friendly role with occasional travel to Ireland for bring-up, testing, and team sessions.
