We are hiring an Embedded Engineer who can own hardware design and firmware development end-to-end. This is a hands-on, build-things role, not a management or architecture-only position.

Hardware Design

The core responsibilities for the job include the following:

Own PCB schematic design and layout for new product SKUs and revisions of existing products.
Select components and define BOMs evaluating MCUs, sensors, power management ICs, GNSS/GSM modules, CAN transceivers, and passives for cost, availability, and performance.
Design and integrate sensor interfaces: temperature (NTC, OneWire, RS485), humidity, wind speed, rain gauge, IMU/accelerometer.
Design relay and control circuitry for applications like compressor controllers (cold chain).
Work with the testing team to validate prototypes, debug hardware issues, and iterate to production-ready designs.
Manage the full cycle from schematic to prototype to production-ready board.

Firmware Development

Write, maintain, and extend firmware in C/C++ on ARM Cortex-M and similar MCUs.
Work with our existing RTOS (picoOS),



adding recent peripheral drivers, sensor integrations, and communication protocols.
Implement and maintain CAN/CAN-FD protocol stacks for vehicle and BMS integrations.
Handle OTA/DFU firmware update mechanisms for devices deployed in the field.
Implement power management, sleep modes, and battery optimisation for field-deployed IoT devices.
Debug device-side issues: sensor data anomalies, communication failures, and field edge cases.

Collaboration And Documentation

Work closely with the software team to define firmware-to-server data protocols and ensure clean handoffs between device and backend.
Document every design decision, schematic, BOM, firmware architecture change, and integration. If it's not documented, it didn't happen.
Participate in weekly team meetings and proactively share progress, blockers, and technical context with the broader team.
Support procurement with technical specifications
