Embedded IoT Engineer — Asset Tracking

About the project

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.

What you'll do

• 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

You're a fit if you

• Are studying or recently graduated in Embedded Systems, Electrical/Computer Engineering, IoT, or a related field
• Have hands-on experience with microcontrollers (ESP32, STM32, 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

Bonus points

• 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

What we offer

• A real R&D project deployed in a real healthcare context — not a tutorial
• 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

Project timeline

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.

Location & format

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.
