Product Design Engineer

About Biotastic:

Biotastic Health Systems is a premium wellness technology company based in Chennai, building India's recovery and performance infrastructure. We design, engineer and manufacture a range of recovery products including ice baths and cold plunge systems, infrared saunas, and red light therapy panels, developed and built in India.

Our products reach customers through both B2B and D2C channels. On the B2B side, we work with gyms and fitness studios, hotels and hospitality groups, sports and performance facilities, and clinics and wellness centres, supporting them through product supply, installation and after-sales service. On the D2C side, we serve individual customers building recovery setups at home.

As a product-first company, our teams work closely across industrial design, mechanical engineering, manufacturing and operations. This role carries real ownership across the development cycle, from concept and CAD through prototyping, vendor coordination, testing and final build. We are looking for people who enjoy solving practical engineering problems and seeing their work go into production.

ABOUT THE ROLE

We are looking for a Product Design Engineer to own the mechanical design of our products, from the first 3D model through to the finished unit leaving our facility.

You will have real ownership here. Because we design and build in the same place, you will see the results of your decisions quickly, learn from them, and improve the next revision. It is a rare level of visibility for an engineer at this stage of their career, and the reason people who like building things tend to stay.

WHAT YOU WILL OWN

1. The 3D master model of every product.

Every cutout, bracket, conduit, cable gland, drain point, sensor pocket, service panel and mounting point drawn before anything is cut on the shop floor. Our rule is straightforward: nothing gets built until it exists on CAD.

2.



Production drawings a fabricator can build from without calling you.

Flat patterns, bend tables, weld callouts, tolerances, surface finish, fastener callouts, and a bill of materials generated from the model rather than typed separately. Drawings carry a version number and a revision history.

3. The sheet metal design.

SS304 and SS316 tub shells, enclosures, frames, chassis and brackets — designed for the bend radii, tooling and weld processes our vendors actually have.

4. Serviceability.

Design the bays and access panels so that the chiller, pump, filter cartridge, UV lamp and controller can all be removed and replaced on a customer site without cutting the product open.

5. Wet and dry separation.

These are electrical products that sit in water. You will route cables, position glands, specify IP-rated enclosures, plan drainage, and keep 230V mains physically separated from low-voltage electronics.

6. The vendor conversation.

Sit with our laser cutting, bending, welding, machining and powder coating vendors and change the design so they can make it at the tolerance, finish and cost we need. Design for manufacturing here means designing for the job shop down the road, not for a theoretical factory.

7. The first-off build.

Be on the floor when the first unit is made. Measure what did not fit, record it, correct the model, and release the next revision.

8. Part count and material cost per unit.

Know what each product costs in material and hardware, and reduce it without reducing quality.

WHAT YOU MUST HAVE

- 1 to 4 years designing products that actually got manufactured. Not concept work,



not CAD support work.
- Sheet metal design, properly. You should be able to explain flat pattern development, bend allowance and K-factor, minimum bend radius, bend relief and weld preparation in the interview, without preparing for it.
- Working knowledge of stainless steel. When to use SS304 and when SS316, what 2B and No.4 brushed finishes are, and how to design around weld distortion and heat tint on a visible surface.
- Production drawing skills. Basic GD&T;, tolerance stack-up, fits and clearances, surface finish symbols, correct title block and revision control. Drawings that a shop can read without a phone call.
- Strong 3D CAD. SolidWorks, Creo, Fusion 360, Siemens NX, Inventor, CATIA, Onshape or Rhino — any of these is fine. What matters is that you are strong in the sheet metal and assembly environments, not only in part modelling.
- Direct vendor experience. You have personally sent files to a laser cutting or press brake vendor, argued about a tolerance, and gone to the shop to check the first piece.
- B.E. / B.Tech in Mechanical, Production or Industrial Engineering, or a Product / Industrial Design degree with strong engineering fundamentals.

GOOD TO HAVE

- HVAC or refrigeration exposure. Our tubs have a refrigeration circuit inside them — compressor, condenser, evaporator, refrigerant line routing, insulation, condensate management and ventilation. Any exposure here is a strong advantage.
- Water system design. Pumps, pipe runs, unions, isolation valves, drain points and leak-free joints.
- Electrical layout awareness in a wet product. IP65 and IP68 ratings, cable glands, earthing, and keeping mains away from water.
- Rendering and visualisation. KeyShot, SolidWorks Visualize, Blender or similar — useful for customer-facing product presentation.
- Startup or small-team experience. There is no drawing office here. You will be the drawing office.
