Multiple board variants

Incremental hardware upgrades

Long-term firmware reuse

OTA updates

Strong security

Design and implement low-power firmware, including sleep/wake strategies, radio usage optimization, and battery-driven operation

Develop firmware for wireless charging-capable battery systems, including charge state management and fault handling

Build and maintain manufacturing and factory tooling, including:

Board test and diagnostics firmware

Programming and provisioning workflows

Calibration and verification utilities

Collaborate with cloud and algorithm teams to define firmware interfaces and data exchange formats

Provide technical leadership through code reviews, architectural guidance, and mentorship
