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 the failure modes
What must never break, what can degrade, and what the audit trail needs to prove.
Build or harden
Implement with OTP supervision, tests, and measurable gates — or review and repair existing systems.
Ship with proof
CI packages, demos, and runbooks so the next engineer can own the system without archaeology.
