About Weenav:

Our company : Weenav is a French start-up based in Roncq (Lille Metropolis), founded by three engineers who were childhood friends — two specialists in intelligent electric vehicles and one expert in information technology. Our core business: to design, equip and integrate high-power electric and hybrid engines on new or existing boats, in the service of cleaner and more pleasant navigation.

‍

Our products:

• KRONOS : Powerful and flexible electric outboard motor, designed for fast boats and dynamic navigation, combining performance and responsiveness.

• ARION : Robust and silent electric inboard motor, integrated into the hold for smooth propulsion, without vibrations, offering optimal navigation comfort.

‍

A turnkey offer : Beyond products, Weenav supports its customers from end to end: technical studies, custom design, on-board integration, regulatory compliance. This integrated approach makes Weenav a trusted partner in a maritime market in profound transformation.

‍

A promising positioning : With 35 million boats in circulation in the world and a market potential estimated at 16 billion dollars over the next decade, Weenav is located at the crossroads of energy transition and demanding nautical uses: sustainability, performance, silence.

• Structuring data for display in the front end

‍

Communication to the central API

• Secure transmission via HTTPS
• Gateway identification management
• Reporting of alerts, errors and status indicators

‍

Integration on a certified IoT gateway

• Deployment and stable execution of software on an industrial module
• Service Management, Logging, Redundancy, and Local Monitoring
• Tests and validation under real conditions (simulation or boat)

‍

Contribution to web monitoring (depending on interest)

• Assist in improving graphs, tables, and visual representations
• Adapt or enrich backend data to facilitate display

‍

Required profile:

Technical skills
