Embedded Systems Internship

Description

The startup Get Your Way develops embedded devices based on ESP32 microcontrollers, used in demanding industrial and hospital environments. These devices run applications developed with the ESP-IDF framework, integrating critical business logic such as communication, state management, display handling, sensors, and user interaction.

Today, a significant part of the testing process is performed manually or directly on hardware, which limits the ability to automatically and reproducibly test the embedded software.

The objective of this internship is to design and implement a complete automated testing infrastructure enabling:

• the writing and execution of unit tests for ESP-IDF-based code,
• the execution of tests through hardware emulation or simulation,
• and/or the execution of tests on a physical board connected to a computer, with the computer acting as an automated test server.

This infrastructure will improve firmware robustness, enable regression detection, and facilitate the integration of embedded software into a continuous integration workflow.

Tasks

The internship will consist of:

1. analyzing the current ESP-IDF firmware architecture to identify testable components and parts requiring abstraction (HAL, drivers, communication layers, business logic)
2. studying available testing tools within the ESP-IDF ecosystem (unit testing frameworks, mocks, test runners, etc.)
3. setting up an automated unit testing structure integrated into the existing project
4. exploring hardware emulation or simulation approaches (partial or full) for ESP32-based systems
5. designing a solution allowing a real embedded board to be connected to a computer, where the computer acts as a test server (automatic flashing, test execution, log collection, result reporting)
6. extending the testing infrastructure to cover LVGL-based graphical components, including UI logic, rendering validation, and event handling
7. automating test execution (nightly or weekend runs) and generating simple test reports
8. documenting the testing infrastructure so it can be easily used and maintained by the development team

The scope of the tasks covered during the internship will depend on its duration.

Key Challenges

• Understanding and navigating an existing ESP-IDF firmware architecture
• Decoupling hardware-dependent code from business logic to improve testability
• Implementing automated tests in an embedded environment
• Handling constraints related to real hardware (timing, communication reliability, stability)
• Testing graphical interfaces built with LVGL in a non-interactive or automated context

We are looking for a motivated student to join our team for an internship in embedded systems development. You will work closely with a small, passionate team and contribute directly to the development of real products used in the field.

You are currently studying computer science, electronics, or embedded systems, and you have a strong interest in low-level development, embedded software, and software architecture. You are comfortable with C/C++ and care about writing clean, well-structured code. Experience with ESP32, ESP-IDF, LVGL, unit testing, or CI tools is a plus, but it is absolutely not required. What matters most to us is your curiosity, your motivation, and your willingness to learn.

You enjoy working independently, taking initiative, and searching for solutions when facing technical challenges.

You are comfortable working in a French-speaking team, and you have a good level of English to read technical documentation and technical resources.

You are curious about innovation, new technologies, and the startup or entrepreneurial world, and you are excited by the idea of building concrete solutions rather than purely academic projects

If you like learning by doing and want to have a real impact, this internship is made for you.

We offer a stimulating and fast-growing environment where you can play an active role in developing innovative solutions and real-world products.

• Flexibility: Partial remote work (up to 1 day per week) and flexible working hours to support a healthy work–life balance.
• Opportunities for growth: As a startup, we offer many opportunities to grow and evolve, depending on your involvement, interests, and ambitions.
• Collaboration: You will join a dynamic team that values collaboration, learning, and knowledge sharing.
• Impact: The opportunity to contribute directly to innovative products that aim to redefine industry standards.
• Learning: A team culture that strongly values continuous learning and skill development, allowing you to grow your expertise through each project while progressing together as a team.
