Full‑Stack IoT Intern (Firmware & QA)

Full‑Stack IoT Intern (Firmware QA)

Are you a student eager to start your journey in the world of IoT, embedded systems, and software quality? Do you want to work on a next‑generation IoT‑enabled Global Wireless Lock Platform that will become the foundation for upcoming ASSA ABLOY wireless lock products?

Join our R&D organization in Kraków and become part of a collaborative, international team developing modern, secure IoT solutions for access control.

This internship is ideal for someone who wants to combine firmware‑level work on a Zephyr RTOS‑based system with test automation in a real production environment.

What you will be doing

As a Full‑Stack IoT Intern, you will work closely with experienced firmware and QA engineers and gain hands‑on experience across multiple layers of the system.

Investigating and troubleshooting issues in a Zephyr RTOS‑based firmware platform
Debugging system‑level and firmware‑level problems
Analyzing logs, device behavior, and protocol communication
Fixing simple bugs or supporting senior engineers in bug fixing
Gaining hands‑on exposure to embedded development in C
Supporting protocol‑level work, including CoAP‑based communication

Testing, QA & Automation

Writing automated tests using Python‑based test frameworks
Contributing to test automation and CI pipelines
Conducting exploratory testing on IoT devices
Preparing test data and test environments
Reporting and tracking defects, and supporting root‑cause analysis

You will work with modern IoT products for the access‑control market, gaining exposure to security standards, cryptography, and wireless communication.

You will also use AI-based tools on a daily basis to support development, testing, debugging, and analysis, learning how modern engineering teams effectively combine expertise with AI-assisted workflows

Your profile

We are looking for a motivated student who wants to grow primarily in embedded firmware, while also contributing to testing and quality.

You should have:

Availability to work at least 3 days per week
Very good English, written and spoken, as you will work in a multinational environment

Student status in Information Technology, Computer Science, Electronics, Automatic Control, Robotics, or a related field
Interest in embedded systems and firmware development
Basic knowledge of C programming or strong willingness to learn
Practical experience with Python
Basic knowledge of RESTful APIs
Interest in testing, quality assurance, and CI

Experience with IoT, Zephyr RTOS, Linux, networking, or electronics is a plus

We want the internship to align with your interests and long‑term development goals. During the interview, we will be happy to hear about your university projects, private projects, or activities in scientific clubs.
