About the role

Key responsibilities & impact

Maintain and improve Home Assistant OS support for Nabu Casa hardware platforms, contributing where appropriate within the wider Home Assistant OS ecosystem.
Work closely with Home Assistant OS contributors and Open Home Foundation developers to improve platform support, resolve issues, and enable new hardware platforms.
Support board bring-up activities for new hardware products, including Buildroot configuration, board support packages (BSPs), bootloader configuration, partition layouts, and system services.
Optimise operating-system performance, hardware utilisation, stability, and reliability across supported devices.
Maintain and improve the Buildroot-based build infrastructure, ensuring builds remain reproducible, maintainable, and efficient.
Investigate and resolve platform-level issues including boot regressions, driver failures, hardware compatibility problems, update issues, kernel panics, and power-management defects.
Collaborate closely with the Hardware Team during development and validation of new boards. The Hardware Team owns hardware design and production; you ensure reliable operating-system support and compatibility.
Upstream patches as required to Linux, U-Boot, Buildroot, or other related open-source projects.
Work with silicon vendors, hardware partners, and open-source maintainers when required to improve platform support and resolve lower-level issues.
Contribute to operating-system security hardening and platform reliability improvements.
Help maintain healthy CI pipelines for operating-system builds and platform validation.
Document platform architecture, board support status, debugging procedures, known limitations, and key technical decisions.
