About This Role
We are seeking a senior firmware engineer with 5–8 years of professional embedded development experience who has strong experience building production embedded systems on modern wireless MCU platforms such as Espressif ESP32. In this role, you’ll work hands-on across 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 connected devices from bring-up through production deployment and ongoing maintenance.
You will develop firmware across the full device lifecycle, including schematic review, board bring-up, driver integration, BLE provisioning, cloud connectivity, 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, contract manufacturers, and cross-functional teams to deliver production-ready devices.
This role involves debugging complex, real-world interoperability issues across connected-device ecosystems, requiring deep protocol-level understanding and hands-on problem solving.
Responsibilities
Design, develop, and maintain production firmware for ESP32-based connected devices using ESP-IDF
Bring up new hardware and integrate drivers for sensors, actuators, LEDs, and other peripherals
Implement BLE provisioning, Wi-Fi connectivity, and secure cloud communication with AWS IoT Core over MQTT
Build and maintain reliable OTA update mechanisms, including rollback and staged rollouts
Debug and resolve issues across firmware, hardware, wireless, and cloud layers, from development through production
Partner with hardware engineers and contract manufacturers on factory flashing, device provisioning, and production readiness
Support certification (e.g., FCC) and hardware build phases (EVT/DVT/PVT)
Collaborate with mobile and backend teams on device data models, telemetry, and device-to-cloud interfaces
Contribute to firmware CI/CD, test tooling, and technical documentation
Requirements
Experience
5–8 years professional embedded/firmware engineering in C/C++
Significant experience with Espressif ESP32 platforms using ESP-IDF, including RTOS-based development, OTA update mechanisms, low-level driver integration (I2C, SPI, UART, ADC, GPIO), and production firmware deployment.
Direct, demonstrable experience developing connected-device firmware on modern wireless platforms such as ESP32, including Bluetooth Low Energy, Wi-Fi, and related connectivity technologies.
Hands-on experience with wireless communication stacks such as BLE and Wi-Fi at the firmware level.
Experience debugging protocol-level communication issues, wireless connectivity problems, device provisioning flows, and interoperability challenges in connected-device ecosystems.
Experience connecting devices to cloud IoT platforms such as AWS IoT Core using MQTT over TLS, including certificate-based authentication and device state synchronization.
Experience integrating sensors, actuators, and peripherals such as RFID readers, accelerometers, motion sensors, LEDs, and pumps.
Comfortable reading technical specifications and translating them into production-quality firmware implementations.
Preferred Qualifications
Contributions to open-source ESP-IDF or nRF Connect SDK project
Background in adjacent protocols — Thread, 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
Experience with Nordic nRF-series platforms using nRF Connect SDK
Familiarity with embedded security concepts such as secure boot, flash encryption, key management, device attestation, and secure firmware updates
Experience designing OTA update strategies with rollback and staged rollouts
Experience working with contract manufacturers on factory flashing, device provisioning, and production readiness
Experience supporting hardware through EVT/DVT/PVT builds and FCC certification
Familiarity with Protocol Buffers or similar serialization formats for device messaging
Python scripting for test tooling and device automation
