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,

‍

Communication to the central API

• Secure sending via HTTPS
• 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
