• Build protocol libraries that connect subsystems (battery management, inverter, IoT module) to each other and to the mobile app.
• Maintain CI/CD in GitHub Actions for firmware builds, tests, and releases; make OTA releases reliable and traceable.
• Work with cloud and mobile engineers on device APIs (AWS IoT), fleet telemetry, and app integration; debug end‑to‑end from radio to app.
• Use AI‑assisted development tools (e.g., Claude Code, GitHub Copilot) to speed prototyping, debugging, testing, and documentation.
• Participate in code and design reviews; document designs for developers, QA, manufacturing partners, and support.

Requirements

• Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field; OR 5+ years of directly relevant experience.
• 3+ years writing production firmware in C/C++ for microcontrollers or SoCs (e.g., Espressif ESP32, Nordic nRF, ST STM32, or other Arm Cortex‑M).
• Experience with a real‑time operating system (e.g., FreeRTOS, Zephyr) and a wireless vendor SDK (e.g., ESP‑IDF, nRF Connect SDK).
• Working knowledge of Wi‑Fi, Bluetooth LE, and an IoT messaging protocol such as MQTT.
• Working knowledge of bootloaders, OTA updates, and device provisioning.
• Working knowledge of serial communication protocols (UART, SPI, I2C, CAN).
• Experience testing embedded code (unit tests, simulation, or hardware‑in‑the‑loop).
• Proficiency in Python and/or JavaScript/TypeScript for build, test, and tooling scripts.
• Experience with Git/GitHub, code review, and CI/CD.
• Experience with AI coding assistants in daily work.

Nice to Have

• Experience with AWS IoT Core or another cloud IoT platform, including REST APIs.
• Experience with mobile app development (native, Flutter, or React Native).
• Experience with smart home protocols such as Matter, Thread, Zigbee, or Z‑Wave.
• Experience with or interest in embedded Rust (e.g., Embassy) or embedded Linux (e.g., Yocto, Buildroot).
• Experience with fleet monitoring, device telemetry, or crash reporting.
• Experience with consumer electronics, batteries, or power conversion.

Benefits

• Comprehensive Healthcare Coverage: Medical, dental, and vision plans with BioLite covering 90–100% of monthly premiums, depending on plan selection.
