As a key member of our growing firmware team, you will own major portions of the embedded software stack from early architecture through production and play a critical role in bringing complex consumer electronics to life. You'll work closely with electrical, mechanical, software, ML, and product teams to transition systems from prototype to robust, production-ready products while helping establish strong firmware engineering practices across the company. What you'll do Embedded Firmware Architecture & Product Development * Contribute to firmware architecture and embedded software development for battery-powered wearable consumer devices from concept through production. * Own critical portions of the firmware stack including realtime data acquisition, connectivity, power management, bootloaders, and production infrastructure. * Develop robust embedded systems using C/C++ and RTOS-based architectures including FreeRTOS or similar environments. * Design and implement reliable firmware abstractions across sensors, audio systems, wireless subsystems, and power domains. * Collaborate closely with electrical, mechanical, ML, mobile, and cloud teams to optimize system performance, latency, power consumption, and reliability. * Operate effectively in a startup environment where engineers own large portions of the hardware and firmware stack. Realtime Embedded Systems & Sensor Processing * Design and optimize low-latency realtime firmware pipelines for sensor acquisition, timestamping, synchronization, and data movement. * Develop DMA-driven acquisition systems for high-throughput sensor and audio streams. * Implement deterministic scheduling and time alignment across multiple sensors and wireless subsystems. * Optimize firmware for low-power operation, including sleep states, subsystem power gating, and dynamic power management. * Debug complex concurrency, timing, and memory-related issues in deeply embedded systems. Wireless Connectivity & Audio Systems * Develop and integrate Bluetooth LE and Classic Bluetooth audio functionality on Qualcomm Snapdragon platforms or similar wireless SoCs. * Work on wireless coexistence challenges involving Bluetooth, Wi-Fi, and proprietary RF systems. * Implement and optimize OTA firmware update systems, bootloaders, and device recovery mechanisms. * Develop and optimize embedded audio pipelines including low-latency streaming, microphone processing, and synchronization. * Collaborate with ML and algorithm teams on audio features including ANC, beamforming, filtering, and related realtime audio systems. Bring-Up, Debug & Validation * Lead firmware bring-up and debugging across embedded compute, sensors, wireless, and audio systems. * Use advanced debugging tools including JTAG/SWD debuggers, oscilloscopes, logic analyzers, protocol analyzers, and lab instrumentation. * Develop automated validation, manufacturing, and regression test infrastructure. * Perform root-cause analysis and resolve complex issues discovered during development, validation, manufacturing, or field deployment. Production Firmware & Reliability * Support EVT, DVT, and PVT builds and help ramp products to mass production. * Design firmware with strong reliability, manufacturability, and serviceability principles. * Develop factory programming, calibration, provisioning, and manufacturing test systems. * Develop and maintain automated test infrastructure including Hardware-in-the-Loop (HIL) systems, regression testing frameworks, and CI pipelines for embedded firmware validation. * Improve firmware robustness through telemetry, logging, automated validation systems, CI infrastructure, and field diagnostics. * Help define engineering standards, development workflows, and firmware best practices across the organization. ## Related Videos - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Playing Pong on a shoulder press machine](https://www.wearedevelopers.com/videos/100140-playing-pong-on-a-shoulder-press-machine) - [Agent Smith Gets Hardware: Autonomous IoT Hacking From Debug Port to Cloud API](https://www.wearedevelopers.com/videos/100258-agent-smith-gets-hardware-autonomous-iot-hacking-from-debug-port-to-cloud-api) - [Car's are Technology on Wheels - Impact of Software and IT Competence in Automotive](https://www.wearedevelopers.com/videos/780-car-s-are-technology-on-wheels-impact-of-software-and-it-competence-in-automotive) - [When Agents Meet Legacy: Never Change a Running System](https://www.wearedevelopers.com/videos/100320-when-agents-meet-legacy-never-change-a-running-system) - [Unleashing the Full Potential of the Arm Architecture – Write Once, Deploy Anywhere](https://www.wearedevelopers.com/videos/940-unleashing-the-full-potential-of-the-arm-architecture-write-once-deploy-anywhere) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Should senior developers refuse interview coding challenges?](https://www.wearedevelopers.com/magazine/29-should-senior-developers-refuse-interview-coding-challenges) - [Dev Digest 134 - Where pixels sing?](https://www.wearedevelopers.com/magazine/477-dev-digest-134-where-pixels-sing) - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology) - [Dev Digest 138 - Are you secure about this?](https://www.wearedevelopers.com/magazine/486-dev-digest-138-are-you-secure-about-this)
