## About the role

We're hiring a Senior Embedded Firmware Engineer to help own the firmware that runs Ironsite's wearable hardware.

## What they're looking for

- 6+ years of hands-on experience shipping embedded firmware on production hardware, with at least one full product lifecycle delivered in wearables, cameras, or IoT devices at real volume
- Deep expertise in C and C++ for embedded systems with real resource constraints. You've written firmware that lived within tight memory, compute, and power budgets
- Strong understanding of ISP core blocks: demosaicing, color correction, lens shading correction, spatial and temporal noise reduction, and HDR/WDR performance
- Hands-on experience with at least one industry-standard microcontroller platform (STM32, nRF, ESP32, or similar) and one embedded RTOS (Zephyr, FreeRTOS, or similar)
- Comfortable reading schematics and datasheets, and using standard hardware lab tools (oscilloscope, logic analyzer, JTAG, protocol analyzers) to debug hardware-software integration issues
- Systems thinking across the full embedded stack. From silicon to the cloud, you understand how firmware decisions propagate up and down
