• 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
• 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. This experience is important because the role requires collaborating within large shared codebases and public contribution 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.
• Five weeks (twenty-five days) of paid time off. • Fourteen days of paid sick leave if your country/laws treat them as unpaid. • Six weeks of paid and six weeks of unpaid parental leave to be used in the first year after birth. • A budget for your work hardware once you start. After three years, you may keep this equipment for personal use. • An annual smart home budget to ensure you keep up-to-date with the latest smart homes offer. • An annual education budget to help you grow and stay on top of your game. • A yearly performance bonus based on company performance. • A 50% contribution to your internet connection fee at your home workspace. • One day every two weeks to work on your personal projects. • If you are currently working on Home Assistant-related side projects, you can spend work time maintaining them.
