JX Marine Technologies Private Limited

Location: Chennai preferred | Remote considered
Commitment: Full-time preferred | Part-time considered
Stage: Pre-prototype, system architecture completed
Compensation: Market-competitive salary + meaningful equity

JX Marine Technologies is building an advanced electric propulsion system for marine applications operating in some of the harshest conditions an engineering system can face.

Saltwater exposure. High temperature. High humidity. Vibration. Limited access to infrastructure. And in many operating environments, no reliable internet connectivity.

We are currently at the pre-prototype stage. Our system architecture is complete, and we are now looking for a Chief Technology Officer to lead the transition from architecture to a working prototype and, ultimately, a field-ready product.

This is a hands-on technology leadership role.

We are not looking for someone to advise the team from a distance. The CTO will work directly with the founding team, make key engineering decisions, build the core technology,



and establish the engineering team as the company grows.

What you will ownYou will lead the development and integration of the core propulsion system.
This includes:
• Bidirectional motor drive and power electronics
• Multi-cell battery systems and intelligent BMS
• Embedded motor control firmware
• Real-time embedded software and task scheduling
• On-device AI inference and predictive fault monitoring
• Thermal management and protection
• System communications and diagnostics
• Hardware and software integration
• Testing, fault isolation and field validation
The system needs to operate reliably in saltwater, heat, and humidity without depending on continuous cloud connectivity.

You will be expected to work across hardware and software boundaries rather than treating them as separate problems.

For example, when a system fault occurs, you should be comfortable moving from measurements at the power stage to firmware behaviou
