Job Description
We are looking for an intern to develop, deploy, and maintain embedded environmental monitoring systems for a rural IoT site. You will work on ESP
32-based sensor nodes, field hardware installation, Home Assistant integration, Cloudflare networking, and system reliability improvements.
Responsibilities
Sensor & Hardware Systems
Install, calibrate, and maintain environmental sensors (temperature, flow, ultrasonic, septic level, TDS, turbidity).
Build and integrate hardware with ESP
32 microcontrollers using ESPHome.
Assemble robust field enclosures (IP-rated boxes, cable glands, waterproof routing).
Diagnose wiring issues, sensor noise, power instability, and field connectivity problems.
Embedded Firmware
Develop and update ESPHome YAML configurations for ESP
32 devices.
Design basic circuits and interface sensors to microcontrollers.
Ensure reliable measurement accuracy and long-term field operation.
Configure sensors, dashboards, entities, automations, and Elasticsearch charts.
Manage the Home Assistant server (Ubuntu + Virtual Box).
Maintain long‑range remote access via Cloudflare Tunnel.
Networking & Remote Access
Configure Cloudflare Zero Trust tunnels for Home Assistant, Linux hosts, and Shinobi CCTV.
Maintain DNS routing, config.yml files, tunnel credentials, and systemd services.
Set up static IPs with Netplan YAML and ensure stable Ethernet‑based networking.
Deploy LAN‑only surveillance systems using Shinobi.
Configure ONVIF/RTSP cameras and low‑power Pi Zero 2W tunnel endpoints.
Maintain a secure, cloud‑independent camera network.
Documentation & Team Support
Maintain sensor indexes, installation guides, and network documentation.
Support capstone project teams with wiring, integration, and embedded system guidance.
Requirements
Must‑Have Skills
Experience with ESP
32 microcontrollers and embedded sensor integration.
Familiarity with ESPHome, YAML, and Home Assistant.
Basic circuit design, wiring, soldering, and hardware assembly.
Networking fundamentals (DNS, static IPs, tunneling, systemd services).
Troubleshooting embedded hardware, sensors, and Wi‑Fi issues.
Nice‑to‑Have
PCB prototyping or electronics fabrication.
Raspberry Pi setup and optimization.
Enrolled or graduated from electrical engineering, software engineering, computer science, or a closely related program.
