Naval Architect

Naval Architect | Bengaluru, on-site | 5+ years

Ci4 (Autonomy + Intelligence)

About the job:

You will own hull design for our autonomous underwater and surface vehicles, from concept and hydrodynamic analysis through structural design, fabrication support, and sea trials. Our culture values deep technical ownership and a strong work ethic. If you are an engineer who likes to build with urgency and purpose, consider applying.

What you will own:

• Hull form design, hydrostatics, and hydrodynamic performance analysis (resistance, powering, stability) for AUVs and USVs
• Pressure hull design, sized and validated against classification society standards and target operating depth
• Structural design and FEA of hulls, fins, propellers, and other hydrodynamic components
• General arrangement (GA) drawings and space allocation across payload, batteries, propulsion, and control systems
• Watertight sealing and integrity design across hatches, penetrators, and structural interfaces
• Direct, on-site coordination with mechanical, systems, and manufacturing teams to take designs from concept through fabrication, integration, and trials

You have:

• 5+ years in naval architecture or ship/submarine structural design, ideally on AUVs, USVs, or submarines
• Working knowledge of classification society rules and how to design to them
• Hands-on experience with hydrostatics, stability, and hydrodynamic performance analysis
• Proficiency in naval architecture and CAD tools plus FEA
• Comfortable working on-site through fabrication, quality checks, and trials, not just at a desk
• Bonus: pressure hull design experience, DMR steel or similar high-strength materials, exposure to Indian Navy or defence procurement standards

About Ci4:

Ci4 builds autonomous platforms and the AI autonomy stack that runs them. We work with the Indian Navy and are backed by investors who believe sovereign defence tech is one of the defining bets of the decade.
