Mechanical Design Engineer

Neurostellar Pvt. Ltd.; Chennai District; On-site; INR 900,000 - 1,500,000; Full time

Job summary

Neurostellar Pvt. Ltd. seeks an experienced mechanical design engineer to own the end-to-end development of Orbit, a consumer wearable for mental fitness. You'll work with industrial designers, electronics engineers, and manufacturers to create compact, ergonomic hardware ready for scaling.

You will drive CAD, DFx, and BOMs, validate with FEA, and prototype using 3D printing and CNC. This on-site Chennai role involves occasional travel to suppliers and assembly lines.

Qualifications

• 4–8 years of mechanical design for consumer electronics or wearables with shipped products.
• B.E./B.Tech in Mechanical Engineering (master's welcome)
• Fluency in a parametric CAD tool for assemblies and drawings.
• Strong GD&T, tolerance stack-up, and DFM knowledge across plastics/metals/silicones/soft goods.

Responsibilities

• Own end-to-end mechanical design for a consumer wearable, including sketches, CAD, drawings, and BOMs.
• Integrate PCBs, batteries, connectors, sensors, and antennas into enclosures balancing function and manufacturability.
• Validate designs with FEA (structural and thermal) and tolerance checks before production.
• Build and test prototypes using 3D printing, CNC, and tooling, plus fixtures.
• Collaborate with external manufacturers through tooling, pilot builds, audits, and ramp to production.
• Tear down and benchmark wearables to sharpen material, design, and DFM decisions.

Job description

You'll own the mechanical design of Orbit, our mental-fitness wearable — from first sketches to production-ready assemblies. Working alongside industrial designers, electronics engineers, and manufacturing partners, you'll make compact, comfortable hardware that holds up at scale.

This is an on-site role at our Chennai facility, with occasional travel (up to 25%) to toolmakers, vendors, and assembly lines.

What you'll do

• Drive end-to-end mechanical design for a consumer wearable — sketches, parametric CAD, detailed drawings with GD&T, and BOMs.
• Integrate PCBs, batteries, connectors, sensors, and antennas into enclosures, balancing function, ergonomics, and manufacturability.
• Validate designs with FEA (structural and thermal) and tolerance stack-ups before parts are cut.
• Build and test functional prototypes with 3D printing, CNC, and soft tooling — plus the jigs and fixtures to support them.
• Work with external manufacturers through tooling, pilot builds, audits, and production ramp; debug part issues and iterate fast.
• Tear down and benchmark other wearables to sharpen material, design, and DFM decisions.

What you'll bring

• 4–8 years of mechanical design for consumer electronics or wearables, on real products that shipped (prototyping- or research-only experience won't be a fit).
• B.E./B.Tech in Mechanical Engineering or related; a master's is welcome but not required.
• Fluency in a parametric CAD tool (SolidWorks, Creo, NX, or Fusion 360) for assemblies and manufacturing drawings.
• Strong grasp of GD&T, tolerance stack-up, and DFM, plus the materials and processes behind plastics, metals, silicones, and soft goods.
• Hands-on prototyping experience and comfort collaborating across industrial design, human factors, and electronics/firmware.
• Basic FEA in CAD-integrated tools for early structural and thermal checks.
• Familiarity with ISO 9001, CE, FCC, RoHS, and tests like IP ratings, thermal cycling, and drop performance.

You'll build at the intersection of neuroscience, design, and engineering — on products people use to understand and train their own minds. Early-stage means real ownership: your work ships, and you watch it land in people's hands.

Neurostellar is an equal-opportunity employer. We value diverse perspectives and welcome applicants from every background.
