Developing production-grade firmware for Matter-enabled devices from bring-up to certification
Owning firmware development across the full device lifecycle, including schematic review, board bring-up, driver integration, OTA updates, and certification readiness
Participating in hardware debugging and validation using tools such as JTAG/SWD, logic analyzers, and protocol sniffers
Collaborating closely with hardware engineers and cross-functional teams to deliver production-ready devices
Debugging complex, real-world interoperability issues across Matter ecosystems (Apple Home, Google Home, Alexa)

10+ years professional embedded/firmware engineering in C/C++
Significant experience with ESP-IDF — not Arduino wrappers, but real ESP-IDF work: CMake/Kconfig build system, partition tables, NVS, OTA frameworks, FreeRTOS task management, and low-level driver integration (I2C, SPI, UART, ADC, GPIO)
Direct, demonstrable work implementing Matter on ESP32-series silicon (ESP32, ESP32-C3, ESP32-S3, or ESP32-H2) using Espressif's ESP-Matter SDK or the upstream Connectedhomeip stack
Hands-on with at least one Matter transport at the firmware level — Wi-Fi or Thread (802.15.4)
Experience debugging commissioning flows, interop failures, and protocol-level issues across ecosystems (Apple Home, Google Home, Alexa)
Familiarity with secure boot, flash encryption, and device attestation in the Matter context
Comfortable reading specs (Matter, Thread, 802.15.4) and translating them into working firmware
Must reside in Colombia
Must be authorized to work without sponsorship on a permanent basis
