At Tejtronics, we are building indigenous RF communication technologies for applications where reliability, ruggedness and performance matter. From RF amplifiers and filters to antennas, communication equipment and supporting hardware, we believe in building products from the ground up — in India for the world!

We are looking for a Mechanical Product Design Engineer who wants to do more than create CAD models. We want someone who enjoys building things, solving real engineering problems and seeing their designs become actual products.

? What You'll Do

As part of our product development team, you will:

- Design mechanical components, enclosures, chassis, brackets, mounts and assemblies for RF and electronic products.
- Develop mechanical solutions for RF amplifiers, filters, radios, antennas and associated hardware.
- Create detailed 3D CAD models, assemblies, engineering drawings and BOMs.
- Design for manufacturability, assembly, serviceability and cost.
- Work with materials and processes including aluminium, sheet metal, CNC machining, welding, laser cutting and 3D printing.
- Build and iterate prototypes and work closely with the workshop and manufacturing vendors.
- Work with RF and electronics engineers on mechanical integration, thermal management, heatsinks and enclosure design.
- Design mechanical systems involving bearings, shafts, gears, fasteners and moving mechanisms, where required.
- Participate in prototype testing, troubleshooting and design improvements.
- Work with vendors and fabricators to take designs from CAD to manufactured hardware.
- Maintain engineering drawings, revisions, BOMs and other product documentation.

? What We're Looking For

Must Have

- Strong problem-solving and analytical skills.
- A genuine hands-on engineering mindset.
- B.E./B.Tech in Mechanical Engineering or equivalent.
- 0–2 years of experience in mechanical/product design.
- Solid hands-on experience with a 3D CAD tool such as SolidWorks, Fusion 360, Creo, CATIA or equivalent.




- Good understanding of mechanical design, tolerances, fits, fasteners and material selection.
- Ability to create and interpret engineering drawings and GD&T.;
- Understanding of common manufacturing and fabrication processes.

Good to Have

Experience in one or more of the following will be an advantage:

- RF/electronics enclosure design
- Antenna or RF hardware
- Thermal management and heatsink design
- IP-rated/rugged enclosures
- Aluminium fabrication
- CNC machining
- EMI/EMC considerations
- Rotating mechanisms, bearings, gears or actuators
- Rapid prototyping / 3D printing
- Taking a product from concept → prototype → testing → manufacturing

?️ This Is Not a CAD-Only Job

At Tejtronics, your work doesn't end when the drawing is released.

You'll design it --> Prototype it --> build it --> test it --> improve it --> take real product to customer!

You'll work alongside RF, electronics and embedded engineers, giving you an opportunity to understand how different engineering disciplines come together to build a complete communication system.

? Who Will Thrive Here?

You could be a great fit if you:

- Want to build for Bharat.
- Consider yourself as a soldier of sorts.
- Are curious about RF, antennas and communication technology.
- Want to work in a hands-on deep-tech startup environment.
- Want to see your engineering work deployed in the real world.
- Love building and experimenting with hardware.
- Enjoy taking things apart to understand how they work.
- Are comfortable moving between CAD, workshop and test bench.
- Like solving problems that don't always have a ready-made answer.
- Take ownership rather than waiting for detailed instructions.
- More than anything love working with a cross functional team.

Why Tejtronics?

We are building an indigenous RF hardware ecosystem — with products designed to be:

Indigenous. Modular. Rugged. Repairable. Field-ready.

If you're looking for a role where you can design, experiment, build and learn across engineering disciplines, this could be the place for you.
