What you'll own
The Embedded roadmap and firmware delivery for our ESP32-based controllers, reporting directly to [ CTO / VP R&D ]
A team of engineers across hardware and software, including hardware deliverables (ECOs, ATE)
Architecture: you set the technical direction for new controllers, sensor integrations, and connectivity as we build toward OTA and scale - you don't inherit someone else's standards, you define them
What you'll do
Design, build, and maintain firmware for ESP32-based controllers, hands-on in the codebase daily
Implement and harden IoT communication (MQTT, HTTP, TCP/UDP networking)
Optimize firmware for reliability, performance, memory footprint, and power efficiency
Set the bar for code quality: Git workflows, code reviews, testing, and documentation
Drive architecture decisions with backend and product, and grow the engineers on your team
Requirements
2+ years leading Embedded /firmware engineers as their direct lead (not only Scrum Master or mentoring), within 5+ years of Embedded development
Production firmware shipped on ESP32 or a similar wireless MCU, in C / C ++
Solid grasp of hardware interfaces (GPIO, I2C, SPI, UART) and sensor/peripheral integration
Practical knowledge of MQTT, HTTP, and Embedded networking
Comfort with Git, PlatformIO or Arduino IDE, and reading unfamiliar codebases
Strong communicator who works well across hardware, backend, and product
Nice to have
FreeRTOS or other RTOS experience
OTA update mechanisms
Unit testing for Embedded systems and CI/CD exposure
Experience with ECO processes and automated TEST equipment (ATE)
Why this role
Your code and your team's code run on physical devices in real greenhouses, where a crash means a grower's crop, not a 500 error.
