Home Assistant Python Developer, Hardware

This is a fully remote position, open to applicants in Florida.

📋 Description

• Take charge of integrations and software support for Nabu Casa products within the Home Assistant, ESPHome, and associated Open Home Foundation ecosystems throughout the entire product lifecycle.

• Develop and sustain Python integrations, proxy libraries, and software components that link Nabu Casa products to the Home Assistant and ESPHome ecosystems, with a primary focus on expanding these components initially.

• Create and maintain Python software that interacts with device protocols and hardware peripherals, translating low-level behavior into clean Home Assistant entities and user experiences.

• Work closely with the Embedded Linux OS Engineer and Hardware team to grasp hardware capabilities and translate them into well-organized software integrations.

• Contribute to Home Assistant core, ESPHome, and other related projects as necessary to support integrations, configuration flows, entity models, and platform functionalities.

• Ensure code quality in your areas by writing well-documented, maintainable, and thoroughly tested Python code.

• Review community pull requests and issues related to your integrations, offering clear and constructive feedback to facilitate progress in contributions.

• Investigate and resolve software and integration issues, including protocol edge cases, compatibility challenges, regression bugs, and device communication failures.

• Maintain robust unit, integration, and hardware-in-the-loop test coverage where applicable.

⛳️ Requirements

• Proficient in Python development, including async/await, testing frameworks, type annotations, and scalable software architecture patterns.

• Required: significant experience in contributing to large open-source projects, including public pull requests, code review, and collaborative workflows.

• Experience in building integrations, APIs, automation systems, device communication layers, or software for connected devices.

• Comfortable operating across software and hardware boundaries, with an understanding of device protocols and hardware interaction concepts (deep hardware expertise is not necessary — that will be handled by other team members).

• Familiar with local device and communication protocols such as Bluetooth, Zigbee, USB, UART, mDNS, SPI, I2C, MQTT, or similar technologies.

• Ability to quickly grasp unfamiliar systems and navigate large, complex codebases, along with a talent for discovery: figuring out how complex systems integrate and developing new solutions for greenfield challenges.

• Strong debugging and troubleshooting capabilities across integrations and distributed systems.

• Familiarity with Home Assistant, ESPHome, integrations, configuration flows, entity models, or other related Open Home ecosystem projects is a significant advantage.
