Smart Home Systems

About the Company
Our client is a Dubai-based real estate and hospitality developer building technology-led, longevity-focused living environments. They treat intelligent infrastructure as a core part of the residential and commercial experience, not an add-on. Their teams combine design, engineering and data to create spaces that are responsive, secure and wellness-driven. They are now strengthening their in-house smart systems capability to deliver local-first, privacy-centric automation at scale.

Role Overview
We are seeking a highly skilled and meticulous Smart Home Systems & Automation Engineer to lead the deployment, configuration and structural orchestration of our advanced residential and commercial automation environments. In this role, you will bridge the gap between physical IoT hardware, localized Linux host servers and complex ambient environments. You will create robust, secure, low-latency and highly responsive smart spaces that elevate automated logic into true contextual intelligence.

If you are a passionate homelab enthusiast, a seasoned self-hoster and an expert in local-first hardware networks who prefers resilient, privacy-centric design over fragile cloud-dependent ecosystems, this role is tailored for you.

Technical Stack & Ecosystem

• Smart Home Hubs: Home Assistant Core/OS/Supervised (advanced architecture, custom integrations, Add-ons, HACS)
• Automation Engines: Node-RED (complex visual flows), Home Assistant native automations, YAML Blueprinting
• Hardware & Mesh Protocols: Zigbee (Zigbee2MQTT / ZHA), Matter over Thread, Z-Wave (Z-Wave JS), Bluetooth Proxies
• Infrastructure & OS: Linux (Debian/Ubuntu, CLI systems administration), Docker containers, LXC hardware passthrough
• Voice & Ambient Control: Home Assistant Voice Assist, ESPHome (custom microcontrollers, satellite voice nodes), Piper, Whisper

Key Responsibilities

1. Home Assistant Deployment & Systems Administration

• Architect, deploy and provision production-grade Home Assistant servers across diverse host environments (bare-metal, Docker containers or Linux Containers).
• Manage system administration tasks, including secure remote access setup, automated local/cloud backup configurations, database optimization and underlying Linux kernel/OS updates.
• Supervise the installation, maintenance and secure configuration of critical Supervisor add-ons and Community Store (HACS) integrations.

2. Network & Hardware Orchestration

• Design, build and optimize robust local IoT mesh networks using Zigbee, Matter over Thread and Z-Wave protocols across complex physical properties.
• Execute hardware passthrough configurations (e.g., passing USB coordinators such as Sonoff ZBDongle-E or SkyConnect safely from Linux hosts to specific containers/VMs).
• Flash, configure and maintain custom hardware peripherals using ESPHome for localized presence detection, environmental telemetry and smart sensor logic.

3. Advanced Scene & Automation Engineering

• Build elegant, maintainable and deeply complex state machines and multi-condition automations using Node-RED and Home Assistant scripts.
• Program context-aware physical environments by engineering intricate room schemas, behavioral scenes, adaptive lighting profiles and climate routines.
• Develop local-first, privacy-focused voice control topologies using Home Assistant Assist, managing speech-to-text (Whisper) and text-to-speech (Piper) pipelines.

4. Diagnostics & System Resilience

• Monitor network topologies, debug complex state discrepancies via WebSocket/MQTT traffic and trace log structures to resolve device dropouts or timing collisions.
• Ensure maximum system uptime by engineering strict fallback behaviors for when the main internet connection or individual mesh nodes experience hardware failure.

Required Experience & Skills

• Experience: 3+ years of professional or extensive homelab systems engineering experience, with a heavy focus on IoT networking, Linux administration or smart space deployments.
• Home Assistant Mastery: Deep conce
