IoT & Software Developer

About the role

JARK World is looking for a hands-on IoT & Software Developer who is comfortable working at the intersection of hardware and software. You’ll design, build, and deploy connected devices and the software that powers them — from wiring up sensors on a Raspberry Pi to writing clean Python services and managing Linux-based systems. This role is ideal for someone who enjoys prototyping, debugging on real hardware, and seeing their code run in the physical world.

Key responsibilities

• Design, develop, and maintain IoT solutions using Raspberry Pi and other single-board computers or microcontrollers such as Arduino and ESP32.

• Write, test, and deploy Python applications and scripts for device control, data acquisition, automation, and local processing.

• Interface with sensors, actuators, and peripherals using GPIO, I2C, SPI, UART, MQTT, HTTP/REST APIs, WebSockets, and related communication protocols.

• Set up, configure, and administer Linux environments including Raspberry Pi OS, Ubuntu/Debian, networking, systemd services, cron jobs, and shell scripts.

• Build dashboards or simple monitoring UIs using tools such as Grafana, Node-RED, or lightweight web frontends, and store sensor data in SQLite, MySQL/PostgreSQL, or time-series databases.

• Debug hardware-software integration issues with logs, multimeters, logic analyzers, circuit diagrams, datasheets, and careful test procedures.

• Document code, wiring diagrams, deployment procedures, and collaborate with hardware, product, and QA teams to move prototypes toward production.

Required skills & qualifications

• Bachelor’s degree or diploma in Electronics, Electrical, Computer Science, Mechatronics, or a related field.

• 0–4 years of experience in IoT, embedded systems, or software development; strong academic, hobby, or personal projects count.

• Strong proficiency in Python, including libraries such as RPi.GPIO, gpiozero, paho-mqtt, requests, Flask, or FastAPI.

• Hands-on experience with Raspberry Pi: OS setup, GPIO programming, peripheral interfacing, SSH/headless operation, and device troubleshooting.

• Solid working knowledge of Linux command line, bash scripting, package management, networking basics, services, and scheduled tasks.

• Good understanding of electronics fundamentals: voltage, current, resistors, transistors, relays, sensors, power supply basics, and reading schematics.

• Familiarity with Git and the ability to troubleshoot across the full stack — from hardware wiring to application code.

Good to have

• Experience with ESP32/ESP8266, Arduino, STM32, C/C++ embedded programming, PCB tools such as KiCad/Eagle/EasyEDA, or cloud IoT platforms.

• Exposure to Docker on edge devices, Wi-Fi/BLE/LoRa/Zigbee/GSM modules, OTA updates, device fleet management, or edge AI with OpenCV/TensorFlow Lite.

• Frontend basics in HTML, CSS, or JavaScript for building lightweight monitoring dashboards.

What we offer

• Opportunity to work on end-to-end IoT products — from hardware prototypes to cloud-connected systems.

• Fast learning curve, real ownership from day one, mentorship from senior engineers, and a collaborative team culture.

• Access to lab equipment, dev kits, hardware budgets for prototyping, flexible work support, and competitive compensation based on experience.
