Job description

We are a healthcare technology company revolutionizing patient safety across more than 400 behavioral health facilities nationwide. Our mission is to enhance clinical care through advanced sensing, edge computing, and secure cloud integration, combining machine learning, BLE-AoA location tracking, and mmWave radar into real-world IoT systems that save lives.

As a Junior Embedded Software Engineer, you will collaborate closely with hardware, firmware, and cloud teams to design, test, and deploy intelligent sensing devices used every day in hospitals and behavioral health facilities. You will help ensure the reliability, performance, and scalability of a nationwide network of connected safety systems.

What You’ll Do

• Develop and maintain C/C++ firmware for custom IoT devices, from sensor drivers and BLE protocols to application logic on bare‑metal and FreeRTOS systems.
• Collaborate with the hardware team on board bring‑up, sensor integration, and low‑power optimization.
• Automate hardware‑in‑the‑loop (HIL) tests using UART/SWO, BLE, SCPI, and websocket interfaces.
• Validate new sensors and firmware releases for accuracy, reliability, and power efficiency.
• Create clear, repeatable documentation for flashing, testing, and calibration procedures.
• Partner with software and cloud engineers to integrate embedded systems with our AWS‑based IoT and analytics platform.

Minimum Qualifications

• Proficiency in C/C++ with hands‑on experience using entry‑level embedded toolchains (Arduino, PlatformIO, etc.).
• Working knowledge of Python for data collection and test automation.
• Strong analytical and debugging skills.

Preferred Skills

• Familiarity with oscilloscopes, multimeters, and DC power supplies.
• Ability to read schematics and interpret datasheets.
• Knowledge of UART, SPI, I²C, Ethernet, and BLE protocols.
• Experience with vendor SDKs such as STM32CubeMX, ESP‑IDF, or Nordic SDK.
• Understanding of Bluetooth Low Energy (BLE) and basic networking (UDP/TCP, websockets).
• Experience with Git and collaborative version control workflows.
