Embedded Software Engineer

The company is looking for a skilled and self-directed Embedded Software Engineer to join a small, fast-moving team. This role is central to bringing the biosensor platform to life - owning the firmware architecture that bridges raw sensor data with wireless transmission, mobile applications, and clinical dashboards. You’ll work closely with electrical engineers, data scientists, and product leads to define and implement the embedded systems that power a truly novel health monitoring device., * Design, develop, and maintain firmware for ultra-low-power microcontrollers and SoCs in a resource-constrained, body-worn environment

• Implement and optimize Bluetooth Low Energy (BLE) communication stacks for reliable, real-time data transmission to mobile devices
• Develop drivers and middleware for analog front-end interfaces, sensor peripherals, and onboard data acquisition systems
• Build and maintain a robust real-time operating system (RTOS) environment, including task scheduling, power management, and interrupt handling
• Collaborate with electrical engineers to define hardware-software interfaces and support bring-up and debugging of new board revisions
• Implement signal processing algorithms and data compression techniques optimized for embedded execution
• Develop over-the-air (OTA) firmware update capabilities and device provisioning workflows
• Write clean, well-documented, and testable code; establish and enforce firmware coding standards across the team
• Design and execute firmware verification and validation protocols in support of regulatory submissions (FDA, CE)
• Contribute to technical documentation, IP development, and design history file maintenance
• Support the transition from prototype to manufacturable product by hardening firmware/software for reliability and scalability
• Perform other duties as the role evolves in a startup environment

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a closely related field
• 3+ years of hands-on embedded software development experience in a product or R&D environment.
• Strong proficiency in C and/or C++ for embedded systems development.
• Demonstrated experience with BLE protocol stacks and wireless communication in embedded applications
• Solid understanding of RTOS concepts including task management, memory allocation, and low-power optimization.
• Experience writing and debugging hardware drivers for SPI, I2C, UART, and similar interfaces.
• Comfortable working in ambiguous, resource-constrained startup environments with shifting priorities.
• Strong debugging skills using tools such as JTAG, oscilloscopes, and logic analyzers.

Preferred:

• Experience developing software for medical devices or wearable consumer electronics
• Familiarity with FDA design controls, IEC 62304 (medical device software lifecycle), or similar regulatory frameworks
• Background in biosignal acquisition, electrochemical sensing, or analog front-end integration
• Experience with Nordic Semiconductor, STM32, or similar low-power SoC platforms commonly used in wearable applications
• Exposure to mobile application integration (iOS/Android) and cloud data pipeline architecture
• Familiarity with secure firmware development practices and cryptographic protocols

A well-funded health technology startup is developing a first-of-its-kind wearable biosensor platform for continuous, non-invasive health monitoring. This is an early-stage, high-impact opportunity to help build the software foundation of a platform with significant implications for chronic disease management and personalized medicine.
