Senior Electromechanical Engineer

Department: TEC Electrical & Battery

Experience Level: 6–9 Years

Location: Chennai, India

Position Type: Full-Time / New Role

As a Senior Electromechanical Engineer, you will own the physical packaging, structural housing, and mechanical integration of our high-voltage battery modules and electrical powertrain systems into the eVTOL airframe. This is a highly cross-functional role bridging electrical power architectures and structural mechanics. You will transform complex electrical systems into flight-ready, structural assemblies, ensuring optimal thermal paths, structural integrity under high-g flight envelopes, and strict optimization for aircraft weight and mass balance.

• Enclosure & Packaging Design: Design robust, lightweight, and crash-worthy enclosures, mounts, and structural brackets for high-voltage battery packs, power electronics, power distribution units (PDUs), and inverter modules.

• Advanced 3D Modeling: Utilize CATIA V5/V6 (3DEXPERIENCE) to build complex electromechanical assemblies, leveraging surface modeling for aerodynamic integration and airframe routing constraints.

• Precision Engineering & GD&T: Apply rigorous Geometric Dimensioning & Tolerancing (GD&T) principles per ASME Y14.5 to ensure flawless fitments between machined enclosures, sheet metal shields, and composite airframe interfaces. Perform detailed tolerance stack-up analyses.

• Design for Excellence (DfM / DfA / DfT): Inject Design for Manufacturing, Assembly, and Testing principles early into the development lifecycle to drive down component counts, minimize assembly cycle times, and simplify shop-floor production.

• Material & Structural Selection: Select and qualify aerospace-grade alloys, high-performance plastics, structural adhesives, and advanced Thermal Interface Materials (TIMs) to maximize heat dissipation while ensuring structural safety.
