Embedded Firmware Engineer
Own the firmware that runs on our low-power sensors, cellular modems, and edge compute gateways.
Remote (US) / Dallas, TXFull-timeHybrid$130,000 - $175,000
About the role
Our hardware lives on remote leases with bad power and worse connectivity. You will write the firmware that keeps it reliable: low-power sampling, store-and-forward telemetry, OTA updates, and cellular/Starlink failover logic that never loses a reading.
What you'll do
- ▸Develop and maintain C/C++ firmware for ARM Cortex-M sensor nodes
- ▸Build robust store-and-forward and OTA update paths over LTE and Starlink
- ▸Optimize power budgets for multi-year battery and solar deployments
- ▸Work directly with EE and mechanical on new hardware bring-up
- ▸Instrument devices so field failures are diagnosable remotely
What we're looking for
- ▸4+ years embedded C/C++ on resource-constrained MCUs
- ▸Hands-on with LTE-M / NB-IoT / cellular modem AT stacks or equivalent
- ▸Experience with RTOS, MQTT, and low-power design
- ▸Comfortable with oscilloscopes, logic analyzers, and real bring-up work
- ▸Bonus: industrial or oil & gas telemetry experience
Benefits
- ▸Remote-friendly with quarterly field trips
- ▸Health, dental, and vision
- ▸Home lab and equipment budget
- ▸Equity participation
