About Symbionic

Symbionic develops prosthetic and assistive products for people with upper-limb loss. We build practical products that help users perform everyday activities with greater independence.

We are looking for a hands-on Mechanical Design Engineer with strong Fusion 360 skills, a good understanding of engineering drawings, and the ability to execute quickly. Your immediate focus will be developing new prosthetic sockets and preparing selected product components for injection moulding.

Key responsibilities

- Design and improve prosthetic sockets, mechanical components, and assemblies using Autodesk Fusion 360.
- Work with our prosthetist and engineering team to translate fitment, comfort, and functional requirements into practical designs.
- Create well-structured parametric models that are easy to modify.
- Develop prototypes, evaluate assembly and functionality, and implement design improvements.
- Produce detailed engineering drawings with appropriate dimensions, tolerances, fits, materials, and assembly requirements.
- Prepare plastic components for injection moulding, considering draft angles, wall thickness, ribs, bosses, undercuts, and parting lines.
- Coordinate with manufacturing vendors and mould makers to resolve design feedback and support tooling trials.
- Maintain BOMs, design revisions, drawings, and test records.
- Own assigned work from requirement to tested design, meet agreed deadlines, and communicate blockers early.





Required skills and experience

- Strong proficiency in Autodesk Fusion 360, including parametric modelling, assemblies, and engineering drawings.
- Good understanding of mechanical design fundamentals, tolerances, fits, and material selection.
- Practical knowledge of plastic component design and injection moulding requirements.
- Ability to create clear engineering drawings that vendors can manufacture from.
- Hands-on approach to assembling, measuring, testing, and troubleshooting physical products.
- Ability to work independently, make practical decisions, and complete design iterations quickly.
- Bachelor’s degree or diploma in Mechanical Engineering or a related discipline, or equivalent relevant experience.

Good to have

- Experience taking a component through mould development, tooling trials, and production.
- Familiarity with 3D printing and other prototyping processes.
- Experience with prosthetics, wearable products, ergonomic design, or scan-based modelling.

What we value We value engineers who build, test, learn, and finish. You should be comfortable moving beyond CAD, checking whether your design works physically, and following through on improvements.

How to apply

Apply with your CV and examples of two or three relevant projects. Include CAD models, engineering drawings, or photographs of physical components where available.

Briefly explain your contribution, how each part was manufactured, and one engineering problem you solved. Clearly distinguish manufactured parts from concepts or renders.

Shortlisted candidates will be invited for a portfolio discussion and a practical design assessment.

Pay: ₹15,000.00 - ₹30,000.00 per month

Work Location: In person
