Embedded firmware & OS
Bring-up, control loops, and ultra-low-power firmware with fail-closed safety for real hardware.
What it is
Firmware work here starts at power-on: clocks, drivers, RT paths, and the control loop that must fail closed when sensors or comms lie.
Fleets use the same ops discipline as the backends — Phoenix consoles, MQTT, Nerves simulation, ESP-IDF nodes — so a device in the field is not a snowflake SSH session.
Who it is for
Hardware teams that need bring-up, control loops, or fleet telemetry — and cannot ship a fail-open actuator.
Capabilities
- Bring-up on Nerves, ESP-IDF, AVR, dsPIC, and industrial MCUs
- Fail-closed safety around pumps, actuators, and sensors
- MQTT fleets with a LiveView operations console
- Driver work, interrupt priority, and hardware debug
How we engage
- Reproduce the board: power, clocks, and the first failing interrupt
- Make the unsafe state unrepresentable in the control loop
- Handoff with a console, not a tribal-knowledge cable
How we work
Scope
What cannot go down, what can degrade, and what the audit trail must prove.
Build or harden
Implement under supervision and tests — or review and repair what you already run.
Ship with proof
CI artifacts, a demo you can click, and a runbook the next engineer can own.
