Embedded IoT Engineer — Hospital Asset Tracking

Internship Embedded / IoT Hybrid
· Semarang 4–6 months

Build a real‑time RFID‑based asset tracking prototype for hospital environments — end‑to‑end, from hardware schematic to firmware to a basic monitoring dashboard. Open to students, recent grads, and project‑based contractors.

Hospitals manage tens to hundreds of movable medical devices daily — infusion pumps, wheelchairs, portable monitors, ventilators, inpatient beds, surgical tools — and losing track of them costs staff time, delays patient care, and inflates equipment budgets. Most existing real‑time location systems are expensive, proprietary, and require heavy infrastructure, putting them out of reach for mid‑sized facilities.

We’re prototyping a compact, low‑cost embedded asset‑tracking system using RFID and wireless communication that mid‑sized hospitals can actually afford and deploy. The system has four parts: tracker tags on assets, a reader/gateway unit, a backend processing layer, and a monitoring dashboard.

• Define hardware and firmware requirements based on the hospital operating environment
• Select the microcontroller, communication module (Wi‑Fi / BLE / LoRa / MQTT), and RFID components
• Design the schematic and assemble a working tracker node + gateway prototype
• Develop firmware: tag reading, sleep/wake cycles, data formatting, wireless transmission
• Integrate the gateway with a backend API and a basic monitoring dashboard
• Run indoor range tests, power consumption measurements, interference and reliability tests
• Optimize for low power and produce technical documentation, demo video, and final report

• Are studying or recently graduated in Embedded Systems, Electrical/Computer Engineering, IoT, or a related field
• Have hands‑on experience with microcontrollers (ESP
  32, STM
  32, Arduino, or similar)
• Are comfortable writing C/C++ for embedded firmware
• Understand wireless communication basics — Wi‑Fi, BLE, RFID, MQTT, or similar protocols
• Can build a simple frontend dashboard (HTML/JS) to visualize sensor data
• Are curious about healthcare technology and motivated by real‑world impact
• PCB design experience or low‑power hardware optimization
• Familiarity with REST APIs and basic backend development
• Past project work in IoT, sensor networks, or healthcare‑adjacent domains
• Comfort presenting technical work to non‑technical stakeholders

• A real R&D project deployed in a real healthcare context — not atutorial
• Weekly 2‑hour mentoring sessions with a senior mentor
• On‑call access to senior engineers in software architecture, data engineering, full‑stack, and embedded systems
• Hybrid work — Semarang office or remote, your choice
• Stipend (negotiable based on experience and scope)
• Letter of recommendation, project portfolio piece, and demo video for your CV

The project runs 4–6 months across five phases: research and requirements, system design, hardware prototype + firmware development, testing and optimization, and final improvements + documentation. Start date is flexible.

Hybrid. Hardware bring‑up and integration testing happen at our Semarang office (Jl. Gunung Sawo No. 17). Firmware, backend, and dashboard work can be remote.
