Mechanical Engineer — Product Design & Prototyping

Visakhapatnam, Andhra Pradesh | Full-Time | On-site

Your job description will be visible to anyone that views this job.

Dentic World Private Limited is India‘s first dedicated facilitator and innovation hub for the entire dental fraternity — bringing together clinicians, innovators, startups, and engineers to ideate, design, develop, and commercialise cutting-edge dental technology products.

We are on a mission to accelerate the indigenisation of hardware-based dental products across all disciplines of dentistry — including:

• Restorative & Prosthodontics
• Orthodontics
• Endodontics
• Periodontics
• Oral Surgery & Diagnostics
• Oral Cancer Screening & Point-of-Care Devices
• Preventive Oral Care & Dental Hygiene
• Tele-Dentistry & Remote Patient Monitoring

From smart intra-oral devices to connected dental instruments, diagnostic platforms to AI-assisted screening tools — Dentic World is building the future of dentistry in India , one innovation at a time.

This is a hands-on, build-it-yourself engineering role. We are looking for a Mechanical Engineer who is equally comfortable in a CAD environment and on the workshop floor — someone who can take a clinical concept from a rough sketch to a functional prototype with speed, precision, and ingenuity.

At Dentic World, our mechanical engineer will be the backbone of the physical product development cycle. You will work directly with our in-house innovation team and in collaboration with INDQ Product Design Studio — one of India‘s most experienced MedTech product design firms — to design, simulate, prototype, test, and iterate dental hardware products that are destined for real clinical environments.

If you thrive in environments where no two days are the same, where your CAD file becomes a real physical object by end of the week, and where your material choices will eventually be inside a patient‘s mouth — this role is built for you.

Pillar 1 — CAD Modelling & Design Engineering:

• Develop detailed 3D CAD models and 2D manufacturing drawings for dental hardware components and assemblies using SolidWorks, Fusion 360, CATIA, or equivalent
• Apply GD&T (Geometric Dimensioning & Tolerancing) principles to ensure precision and manufacturability across all design outputs
• Perform tolerance stack-up analysis to validate fit, form, and function of multi-component assemblies
• Manage and maintain a structured version-controlled design library — from concept sketches through to release-level drawings
• Collaborate with industrial designers at INDQ Product Design Studio to translate aesthetic and ergonomic intent into manufacturable mechanical forms
• Design for Manufacturability (DFM) and Design for Assembly (DFA) — ensuring every design is optimised for the intended production pathway

Pillar 2 — Rapid Prototyping & Subtractive / Additive Manufacturing:

• Execute hands-on rapid prototyping using both additive manufacturing (FDM, SLA, SLS, PolyJet) and subtractive manufacturing (CNC milling, turning, EDM, laser cutting) techniques
• Operate and programme desktop CNC machines and 3D printers; manage prototyping workflows from file preparation to post-processing and finishing
• Select appropriate prototyping method based on fidelity requirements, material properties, and cost — balancing speed with accuracy at each development stage
• Conduct iterative prototype builds, physical testing, and design refinement cycles — documenting all versions, observations, and failure modes systematically
• Prepare and evaluate surface finish, dimensional accuracy, and fit of prototype assemblies; apply secondary processes (sanding, painting, coating, heat treatment) as required
• Support PoC (Proof of Concept) and pre-production prototype builds for all active innovations at Dentic World

Pillar 3 — Materials Engineering & Simulation:

• Lead material exploration and selection for dental device components — with deep consideration of biocompatibility, sterilisation compatibility, mechanical performance, and regulatory requirements (ISO 10993, ISO 13485)
• Evaluate medical-grade materials including titanium alloys, stainless steel (316L), PEEK, medical-grade ABS/PC/PP, silicones, and dental-specific ceramics and polymers
• Run mechanical simulations including FEA (Finite Element Analysis) for structural integrity, stress and strain analysis, fatigue life, and thermal performance using ANSYS, SolidWorks Simulation, or Abaqus
• Conduct dynamic simulation and motion analysis for mechanical assemblies with moving parts (hinges, actuators, spring-loaded mechanisms, instrument handles)
• Assess and validate material performance through physical testing (tensile, compression, hardness, fatigue); interpret test results and feed findings back into design iterations
• Maintain a structured materials database and testing log for all active projects

Pillar 4 — Cross-functional Engineering & Documentation:

• Work closely with the embedded systems and electronics engineering teams to design and integrate mechanical housings, enclosures, and mounting systems for PCB assemblies and sensor modules
• Apply DFMEA (Design Failure Mode and Effects Analysis) at the design stage to proactively identify and mitigate mechanical failure risks
• Develop and maintain comprehensive engineering documentation: design specifications, test protocols, build-of-materials (BoM), assembly instructions, and design history files (DHF) aligned with medical device development standards
• Support regulatory and IP documentation — providing mechanical drawings, design rationale, and material justifications for patent filings, technical dossiers, and pre-submission packages
• Interface with external vendors, tooling shops, and manufacturing partners to obtain quotes, evaluate capabilities, and manage prototype fabrication timelines

Education:

• Bachelor‘s or Master‘s degree in Mechanical Engineering, Manufacturing Engineering, Mechatronics, or Biomedical Engineering
• Candidates with additional exposure to medical device design, industrial design collaboration, or MedTech product development are strongly preferred

CAD & Simulation Tools (Must-Have):

• Proficient in at least one major CAD platform: SolidWorks (preferred), Fusion 360, CATIA, or Creo — with demonstrated ability to produce complex multi-part assemblies and manufacturing drawings
• Working knowledge of FEA simulation tools: SolidWorks Simulation, ANSYS Workbench, or Abaqus
• Familiarity with GD&T standards (ASME Y14.5 or ISO 1101) and their application in manufacturing drawings
• Understanding of PDM/PLM systems for design version control and release management

Manufacturing & Prototyping Skills (Must-Have):

• Hands-on experience with additive manufacturing (FDM, SLA, or SLS) — including machine operation, file preparation, support strategy, and post-processing
• Practical working knowledge of subtractive manufacturing processes — CNC milling, turning, and at least one of: laser cutting, waterjet, EDM
• Ability to read and interpret engineering drawings and convert them into workshop-ready instructions
• Strong understanding of manufacturing tolerances, surface finish specifications, and their impact on part performance

Good to Have:

• Exposure to medical device design standards: ISO 13485 (Quality Management), ISO 10993 (Biocompatibility), IEC 60601 (Electrical Medical Devices)
• Experience with electromechanical product design — integrating mechanical housings with PCBs, sensors, or actuators
• Knowledge of injection moulding design: draft angles, wall thickness, gate placement, and tooling considerations
• Experience with reverse engineering using 3D scanning or photogrammetry
• Familiarity with material testing standards and lab equipment (UTM, hardness testers, roughness profilometers)
• Exposure to DFMEA, design verification protocols, and design history files (DHF)

Experience: 1–4 years of hands-on mechanical design and prototyping experience, preferably in a product development, MedTech, consumer hardware, or precision engineering environment. Fresh graduates with an exceptionally strong portfolio of self-initiated projects and prototype builds are encouraged to apply.

Within the first 90 days, success will be measured by:

• Functional prototype(s) built and tested for at least one active Dentic World innovation — with documented design iterations
• A clean, version-controlled CAD library established for all assigned projects
• At least one FEA simulation report submitted and reviewed for a component under development
• Material selection documented with rationale for at least two active product components
• Active, productive working relationship established with the electronics team and INDQ collaborators
• Engineering documentation (BoM, assembly notes, design specs) kept current and audit-ready
