About the role

Key responsibilities & impact

Own integrations and software support for Nabu Casa products across Home Assistant, ESPHome, and related Open Home Foundation ecosystems throughout the full product lifecycle.
Build and maintain Python integrations, proxy libraries, and software components that connect Nabu Casa products to the Home Assistant and ESPHome ecosystems — expanding these components is a primary focus initially.
Write and maintain Python software that interfaces with device protocols and hardware peripherals, translating low-level behaviour into clean Home Assistant entities and user experiences.
Collaborate closely with the Embedded Linux OS Engineer and Hardware team to understand hardware capabilities and translate them into well-structured software integrations.
Contribute to Home Assistant core, ESPHome, and related projects where needed to support integrations, config flows, entity models, and platform functionality.
Own code quality within your areas by writing well-tested, maintainable, and well-documented Python code.
Review community pull requests and issues related to owned integrations, providing clear and constructive feedback that helps move contributions forward.
Investigate and resolve software and integration issues including protocol edge cases, compatibility problems, regression bugs, and device communication failures.
Maintain healthy unit, integration, and hardware-in-the-loop test coverage where applicable.

Requirements

What you’ll need

Strong Python development experience, including async/await, testing frameworks, type annotations, and scalable software architecture patterns.
Required: meaningful experience contributing to large open-source projects, including public pull requests, code review, and asynchronous collaboration workflows.
Experience building integrations, APIs, automation systems, device communication layers, or software for connected devices.
Comfortable working across software and hardware boundaries, including understanding device protocols and hardware interaction concepts (deep hardware expertise is not required — that is handled by other team members).
Familiarity with local device and communication protocols such as Bluetooth, Zigbee, USB, UART, mDNS, SPI, I2C, MQTT, or similar technologies.
Ability to quickly understand unfamiliar systems and navigate large, complex codebases — plus a knack for discovery: working out how complex systems fit together and creating new solutions for greenfield problems.
Strong debugging and troubleshooting mindset across integrations and distributed systems.
Familiarity with Home Assistant, ESPHome, integrations, config flows, entity models, or related Open Home ecosystem projects is a strong plus.
