Sr Electrical & ELV Design Engineer – Modular Construction

Sr Electrical & ELV Design Engineer Modular Construction

Location: IITM Research Park, Taramani, Chennai

Join Us in Engineering the Future of Industrialised Construction

We are building a new category of constructionfactory-born, precision-driven, modular building systems designed for scale, speed, and human impact.

Our mission is to revolutionize personal and institutional construction through scientific rigor, DFMA-driven systems, and industrialized workflows. Electrical systems are not an afterthought in this journeythey are central to safety, energy performance, reliability, and lifecycle value.

As Electrical & ELV Design Lead, you will own the electrical engineering backbone of our modular ecosystemfrom load calculations to coordinated BIM sign-offsensuring our buildings are safe, scalable, and manufacturable.

The Role

You will lead end-to-end electrical and ELV engineering design for modular buildings across residential, commercial, institutional, and industrial typologies.

Your mandate is not just complianceit is system optimization for scale, manufacturability, cost-efficiency, and rapid deployment.

You will work closely with:

• Structural & Modular Design Teams
• BIM & Digital Engineering
• Procurement & Supply Chain
• Project Execution & Site Teams
• External Consultants & Approval Authorities
