Job summary

Stic is modernizing out-of-home advertising with edge AI devices that run on vehicles, delivering measurable analytics rather than guesses. The Stic Vision v3.0 is a small, battery-conscious edge device that operates with no external power or maintenance for years.

You will own the embedded firmware stack, bring up hardware, optimize power, integrate sensors and wireless interfaces, and collaborate with hardware, CV, and cloud teams to ship a manufacturable product.

Qualifications

• 3-5+ years of professional embedded software engineering experience.
• Strong proficiency in C, MicroPython and C++ for embedded systems.
• Hands-on experience with BLE firmware development (advertising, scanning, payload design, RSSI logic).
• Experience with RTOS, interrupt handling, and low-level memory management.
• Familiarity with SPI, I2C, UART, and wireless stacks.
• Proficiency with debugging tools including JTAG, oscilloscopes, and logic analyzers.

Responsibilities

• Develop and maintain embedded firmware in C/C++ for microcontrollers and wireless modules powering the Stic Vision v3.0.
• Own OpenMV-based computer vision firmware for person detection, vehicle counting, facial sentiment analysis, and demographic measurement.
• Implement BLE communication stacks — advertising, scanning, data payloads, and RSSI-based logic.
• Integrate cellular (LTE/5G), GNSS, IMU, camera, and sensor interfaces into a unified firmware architecture.
• Build low-power firmware architectures including sleep states, duty cycling, and battery optimization for field-deployed devices.
• Define and implement device-to-cloud and device-to-phone communication protocols.
• Support OTA update pipelines, field diagnostics, and reliability improvements.
• Collaborate with hardware, computer vision, and cloud teams to ensure seamless full-stack integration.
• Contribute to board bring-up, hardware/firmware debugging, and system validation across EVT/DVT/PVT cycles.
