Requirements

• Technical / functional • 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. • Ways of working • High autonomy and ownership mindset — able to independently drive integrations from concept through long-term maintenance. • Comfortable collaborating across distributed teams, cultures, and time zones in a highly asynchronous environment. • Open to feedback — able to take on review comments and adapt, rather than holding rigidly to an approach. • Community-oriented mindset — comfortable contributing publicly and collaborating with external contributors in open-source environments. • Strong written communication skills and ability to explain technical concepts clearly. • Quality-focused while remaining pragmatic and delivery-oriented. • It Would Be Great If You Also Have • Previous contributions to Home Assistant, ESPHome, or related Open Home Foundation projects. • Experience building software for smart home, IoT, or connected hardware products. • Raspberry Pi or embedded Linux ecosystem familiarity. • Experience maintaining software used at large scale across distributed hardware environments. • Experience working in fully remote and async-first engineering teams.
