We're seeking an exceptional firmware engineer to join our core engineering team and help us build lifesaving technology at the intersection of hardware and software. You'll collaborate daily with mechanical, electrical, acoustic, and UX engineers. You'll architect and maintain the firmware that serves as the nervous system of our devices, coordinating signal processing, power management, wireless communication, and user interaction within embedded constraints. You'll collaborate directly with a small firmware team on architectural decisions for both shipping products and next-generation prototypes. This hands-on technical role requires quickly mastering our existing codebase to extract learnings while building new systems, writing production code, and shaping product direction through technical exploration.
This is a hybrid role with required onsite presence on Tue/Wed/Thu.
As Senior Staff Firmware Engineer at Eko, You Will: Design develop and test embedded firmware for next-generation digital stethoscopesMaintain and enhance firmware for currently shipping productsQuickly learn existing codebases and extract learnings for future developmentCollaborate with other firmware developers on architectural decisions, code standards, and system design for a cohesive product portfolioArchitect real-time systems using FreeRTOS and other embedded operating systemsOptimize firmware for code size, RAM usage, and execution efficiency based on system constraintsDevelop and maintain device drivers for peripherals including audio amplifiers, PMICs, displays, sensors, and communication interfacesImplement Bluetooth Low Energy communication stacks and custom characteristicsTransform loosely-defined product concepts into working prototypes, iterating rapidly with the product team to refine specificationsCollaborate with electrical engineers on component selection, schematic review, and system architecture decisionsConduct code reviews, establish firmware best practicesNavigate medical device regulatory requirements and contribute to design control documentation
As Senior Staff Firmware Engineer at Eko, You Have:10+ years of embedded firmware development experienceDeep expertise in C/C++ for embedded systemsProven experience with FreeRTOS, Zephyr, or similar embedded RTOS environmentsStrong understanding of embedded system optimization: code size, RAM footprint, and CPU cycle managementExperience developing bare-metal drivers for I2C, SPI, UART, I2S, and other communication protocolsSolid knowledge of Bluetooth Low Energy (BLE) stack implementation and custom GATT service developmentExperience with ARM Cortex-M microcontrollers (or similar embedded architectures)Proficiency with embedded debugging tools (JTAG/SWD debuggers, logic analyzers, oscilloscopes)Understanding of power management strategies for battery-operated devicesExperience working from electrical schematics and datasheets to implement hardware interfaces
