About Very Very is a fully distributed technology firm led by expert problem-solvers who create efficient, scalable solutions that move commercial, industrial, and consumer products from pilot to production in record time.
We believe that real innovation happens in the grind — working shoulder to shoulder with clients who are building the future.
Our team thrives on that energy.
When we're not helping clients deliver business-critical outcomes, we're refining our craft and celebrating what it means to do hard things well.
We've built a collaborative, tight-knit culture that thrives in both remote and in-person settings.
We've won numerous workplace awards over the years, including Great Place to Work certification and recognition from Parity.org as a Best Company for Women to Advance.
Our clients include well-known brands like Vizio, Peloton, Clear, iHeart Radio, and Fellowes — all determined to leverage connected devices and AI to drive meaningful impact.
Our job is simple: help them win.
About This Role We are seeking a senior firmware engineer with 10+ years of professional embedded development experience who has deep expertise in Matter protocol implementation on Espressif's ESP32 platform using ESP-IDF.
This role requires end-to-end ownership of the device firmware stack, from schematic review and board bring-up through production firmware, OTA, and certification.
What You'll Be Working On We dedicate each engineer to a single project in order to promote focus and minimize context switching.
You will be developing production-grade firmware for Matter-enabled devices from bring-up to certification.
You will own firmware development across the full device lifecycle, including schematic review, board bring-up, driver integration, OTA updates,



and certification readiness.
You will also participate in hardware debugging and validation using tools such as JTAG/SWD, logic analyzers, and protocol sniffers to diagnose low-level issues across firmware, hardware, and network layers.
You'll collaborate closely with hardware engineers and cross-functional teams to deliver production-ready devices.
This role involves debugging complex, real-world interoperability issues across Matter ecosystems (Apple Home, Google Home, Alexa), requiring deep protocol-level understanding and hands-on problem solving.
Must-Haves 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 *********) 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, ********) and translating them into working firmware Location and Residency Must reside in Argentina Must be authorized to work without sponsorship on a permanent basis Strong Signals Contributions to open-source Matter or ESP-IDF repositories Experience taking a Matter device through CSA certification Background in adjacent protocols — Zigbee, Z-Wave, BLE Mesh — demonstrating breadth across the connected device landscape History of working in a consultancy or product development firm where they've shipped across multiple product lines, not just one internal product Comfort with hardware debug toolchains — JTAG/SWD, logic analyzers, protocol sniffers Experience standing up CI/CD for firmware builds and automated test harnesses Skills Can debug complex firmware and hardware interactions under real-time constraints Are comfortable working with incomplete specifications and ambiguous device behavior Take ownership of problems end-to-end, from root cause analysis through production resolution Communicate clearly with both technical and non-technical stakeholders in a client-facing environment This Role Is Likely NOT a Fit If Your ESP32 experience is limited to Arduino IDE or PlatformIO hobby projects Your Matter knowledge is purely theoretical or limited to running the chip-tool demo You don't have experience with real-time debugging or protocol-level troubleshooting You have only worked on a single long-lived product with no exposure to bring-up or new platform work Compensation USD $60 per hour (may be negotiable based on experience) Contract & Scope Independent contractor engagement Expected commitment: ***** hours per week #J-*****-Ljbffr
