About Weenav
Our company
Weenav is a French start-up based in Roncq (Lille metropolitan area), founded by three childhood friends who are engineers - two specialists in smart electric vehicles and one expert in information technology. Our core business: designing, equipping and integrating high-power electric and hybrid propulsion systems on new or existing boats, for cleaner and more enjoyable navigation.
Our products
- KRONOS : Powerful and modular electric outboard motor, designed for fast boats and dynamic navigation, combining performance and responsiveness.
- ARION : Robust and silent electric inboard motor, integrated into the hull for smooth, vibration-free propulsion, offering optimal navigation comfort.
A turnkey solution
Beyond products, Weenav supports its clients from start to finish: technical studies, custom design, onboard integration, regulatory compliance. This integrated approach makes Weenav a trusted partner in a maritime market undergoing profound transformation.
A strong positioning
With 35 million boats in circulation worldwide and a market potential estimated at 16 billion dollars over the next decade, Weenav is at the crossroads of the energy transition and demanding nautical uses: sustainability, performance, silence.
Objectives of the internship
Participate in the development of a complete embedded monitoring system, by:
- Exploiting data from the CAN bus,
- Transforming it into actionable information (electrical values, states, alerts),
- Transmitting it to a remote server,
- And integrating these functionalities into a robust and certified IoT gateway.
Missions
Familiarisation with the existing system

- Management of gateway identification
- Reporting alerts, errors, and status indicators
Integration onto a certified IoT gateway
- Deployment and stable execution of the software on an industrial module
- Service management, logging, redundancy and local supervision
- Testing and validation in real conditions (simulation or boat)
Contribution to web monitoring (depending on appetite)
- Help improve curves, tables and visual representations
- Adapt or enrich backend data to facilitate display
