???? We&aposre Hiring: Senior Mechanical Designer Smart Home Devices (IoT)

Mechanical Designer

Location

Employment Type:

Company Overview

Mantra Softech

Role & Responsibilities:

• Own the mechanical design of smart home products including

  video doorbells, smart locks, switch panels, sensors, and security cameras

  from concept to production.
• Develop

  3D CAD assemblies and production-ready drawings

  using SolidWorks, Creo, or Fusion 360 with a strong focus on

  DFM and DFA

  .
• Design

  rugged enclosures

  optimized for IP ratings, EMI shielding, RF transparency, thermal efficiency, and drop resilience.
• Collaborate with

  Industrial Designers, Embedded Engineers, PCB Layout Engineers, and Antenna teams

  to co-create integrated form factors.
• Balance mechanical requirements with

  cost, material constraints, RF propagation, thermal ventilation, and mass production techniques

  .
• Support

  EVT, DVT, and PVT

  builds and actively resolve mechanical bottlenecks during pilot and mass production.
• Lead

  mechanical validation and reliability testing

  (drop, vibration, humidity, thermal, and fatigue).
• Interface with global vendors for

  tooling, fabrication, material qualification, and tolerance optimization

  .
• Drive reliability through rigorous validation planning (drop, vibration, thermal cycling, etc.).
• Bring a systems-thinking mindset to layout planning, space optimization, battery architecture, and sensor integration.

What We&aposre Looking For

• Bachelors or Masters degree in

  Mechanical Engineering, Mechatronics

  , or a related field

• 48+ years

  of hands-on mechanical design experience in

  consumer electronics or IoT hardware

  .
• Mastery of

  CAD design

  , tolerance stack-up analysis, GD&T, and mechanical documentation.
• Expert-level proficiency in CAD tools like SolidWorks (Preferred), Creo, or Fusion 360
• Hands-on experience with

  injection molding, sheet metal, die casting

  , and

  tolerance stack-up

  for mass production
• Demonstrated ability to solve design problems under

  thermal, ingress protection, or EMI/ESD constraints

• Strong understanding of how

  mechanical decisions impact RF, antenna, and wireless performance

• Experience working with

  global suppliers

  , including reviewing tooling drafts, part validation, and tolerance optimization
• Proven experience in

  plastic injection molding, die casting, sheet metal design

  , and

  IP-rated enclosures

  .
• Deep understanding of

  EMI/ESD shielding

  , thermal management, and how mechanical architecture influences

  RF and antenna design

  .
• Familiarity with

  regulatory and safety standards

  (UL, CE, FCC, BIS, RoHS) and

  design validation workflows

  .
• Experience working with

  CM/ODM vendors

  and participation in prototype-to-production cycles.

• Thermal & Ventilation Design

  - Experience designing enclosures with proper thermal management and ventilation (e.g., airflow analysis, smoke entry grills, ingress protection).

???? You Excel At

• Thinking like a system engineer: understanding how every mechanical decision ripples across hardware and user experience.
• Making thoughtful trade-offs between

  design aesthetics, material costs, and manufacturability

  .
• Collaborating with

  Industrial Designers, Firmware Engineers, and Supply Chain teams

  to deliver a cohesive product vision.
• Communicating clearly across teamsfrom factory floors to product strategy meetings.
• Working under ambiguity and owning the product from

  sketch to shipment

  .

???? Tools & Technologies

• CAD: SolidWorks (Preferred), Creo, or Fusion 360
• Tolerance Analysis: GD&T, stack-up methodologies
• Prototyping: SLA/SLS 3D Printing, CNC, Low Volume DFM
• Simulation (preferred): FEA, CFD, Thermal Analysis

?

???? Why Join

• Impact at Scale

  Shape how smart homes are built and experienced across India and beyond.

• Design-Driven Culture

  Work alongside Industrial Designers who obsess over form, detail, and interaction.

• Innovation at the Edge

  Design for Matter, Thread, BLE, and Wi-Fi enabled devices in a connected ecosystem.

• End-to-End Ownership

  Build and see your work through all phasesfrom 3D sketch to final production.
