Description du poste

Fluidion is an innovative SME focused on developing advanced automated solutions for water quality monitoring: https://fluidion.com/. Our cutting-edge systems perform complex chemical and bacteriological assessments autonomously, offering high-resolution monitoring of chemical and microbiological pollution in various environments—ranging from drinking water reservoirs and recreational areas to natural ecosystems. By reducing risks for users and generating crucial scientific data, our solutions help safeguard public health and the environment.

In addition to our advanced measurement instruments, we design aquatic drones to deploy sensors and create pollution maps, further enhancing the scope of our monitoring capabilities. Our technologies incorporate microfluidics, 3D printing, machine learning, IoT connectivity, and automated data processing, allowing real-time water quality data to be remotely analyzed and visualized by our clients.

Operating internationally, Fluidion partners with private businesses, government bodies, and environmental agencies in cities like Paris, New York, and Los Angeles, and also with large international organizations such as the UN. Notably, in the Île-de-France region, we contribute to major projects such as bacteriological monitoring of the Seine for the Paris 2024 Olympic Games and the active management of La Villette Basin for safe summer swimming. We collaborate with renowned scientific institutes across Europe and the U.S.

Our team is young, diverse, and multidisciplinary. Interns are a key part of our dynamic environment, working on real-world, leading-edge projects. Internship opportunities span fields like microbiology, analytical chemistry, electronics, and business development. Exceptional interns may have the chance to publish their research or join our team after graduation, with possibilities for fixed-term or permanent contracts, apprenticeships, or international assignments through VIE programs.

Why Join Us?

• Rapidly growing company—lots of opportunities
• Young, multidisciplinary, athletic, and international team
• Use of disruptive technologies
• Strong environmental impact
• Nice, dynamic and modern work environment
• Easily accessible by metro

Internship Topic:

As part of the R&D team for electronics and embedded systems, you will help develop the electronic architecture for measurement instruments and aquatic drones used with our analyzers to monitor water quality. You will also contribute to the design of circuit boards and development of embedded intelligence for future product generations.

Example Tasks:

• Conduct literature reviews and stay up-to-date with the state of the art
• Design schematics and layout printed circuit boards (PCBs) using tools like DesignSpark PCB
• Document electronic projects (BOMs, component sourcing, obsolescence studies, etc.)
• Place and track component orders with suppliers
• Assemble, solder, and wire components for prototype fabrication
• Follow safety and lab protocols
• Develop firmware using IDEs (e.g., STM32CubeIDE)
• Develop communication protocols (I2C, SPI, UART, etc.) for interfacing microcontrollers and sensors
• Design embedded graphical interfaces (e.g., using STM32 Discovery boards with touchscreens)
• Write structured, detailed weekly activity reports
• Present monthly technical updates to the full team
• Create Python scripts to interface with sensors, evaluate performance (accuracy, repeatability), and visualize data (e.g., with Matplotlib)
• Collaborate with other team members on multidisciplinary R&D projects

Our internships are rich and varied, involving lab and workshop tasks, software development, data analysis, technical writing, and occasional fieldwork.

Desired Profile

We’re seeking a highly motivated engineering or Master’s student specializing in electronics, with strong skills in embedded systems design and programming. Candidates should be passionate about science and technology, and able to lead projects in both lab and field settings.

If you are creative, tech-savvy, unafraid of hands-on experimentation, and excited by PCB design, microcontroller programming, communication protocols, and embedded systems, you already have the core attributes we value! Prior experience with PCB design, embedded programming, or Python scripting is a plus.

As we are an international team, good communication skills in English are essential. We are looking for autonomous candidates who thrive in dynamic, startup-like environments.

If this sounds like you, welcome aboard!
