Naval Architect | Bengaluru, in office | 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 robust 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 in office 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.
