Senior Mechanical Design Engineer — Special Purpose Machines

Location:
Chandigarh (on-site) | Full time | Minimum 3 years' experience

ABOUT THE ROLE
You will own the mechanical design of our machines, from the customer's requirement to a machine running on their production floor. Beyond modelling and drawing, you are accountable for the design decisions: the concept chosen, the tolerances specified, the manufacturing method selected, and whether the parts that come back from the vendor fit and work. In a special purpose machine business, the designer owns the outcome. The machine has to work, not just look correct on screen. WHAT YOU WILL DO
• Concept and feasibility: develop machine concepts from customer drawings and samples, covering stations, sequence of operations, indexing, feeding and unloading. Estimate and balance cycle time, check feasibility of critical operations, and prepare layouts and 3D views for proposals.
• Detailed design: build the complete machine as a structured parametric assembly in Autodesk Fusion 360. Use joints and motion studies to verify stroke, clearance and interference across the full cycle.
• Machine elements: design frames and weldments, sheet metal guarding, jigs and fixtures, locating and clamping, grippers, pick-and-place units, slides, chutes, conveyors and indexing mechanisms.
• Sizing and calculations: size pneumatic cylinders and select valves and FRL units. Select motors, gearboxes, servo and stepper actuators, bearings, linear guides, ball and lead screws. Document force, torque, inertia, deflection, bolt and weld strength and factor of safety calculations.
• Drawings and BOM: release fully dimensioned manufacturing drawings with correct GD&T;, fits, surface finish, welding and heat-treatment callouts. Prepare the bill of materials and control revisions through an engineering change process.
• Manufacturing and inspection: choose how each part is made (turning, milling,



grinding, wire cut, EDM, sheet metal, fabrication or bought-out). Prepare inspection plans for vendor parts and decide on deviations, rework or rejection.
• Build and commissioning: support assembly on the shop floor, take part in trials and factory acceptance tests, and support site commissioning. Make sure every change made on the floor goes back into the model and drawings.
• Standards: build our standard design library and component library, and turn field failures into design checklists. Review drawings by junior designers as the design team grows.
• Safety: design for operator and maintenance safety, including guarding, interlocks, pinch-point elimination, e-stop reach and ergonomics. WHAT WE ARE LOOKING FOR
• Diploma or B.
E./B.
Tech in Mechanical, Mechatronics, Production or Automobile engineering.
• Minimum 3 years in an automation company, special purpose machine builder, or tooling and fixture design house.
• Good working knowledge of Autodesk Fusion 360: parts, assemblies and joints, sheet metal, weldments, motion study and drawings. Strong SolidWorks, Inventor or Creo users who are willing to switch are welcome.
• Good command of GD&T;, and the judgement to know which dimension needs a tight tolerance and which does not.
• A firm grasp of engineering fundamentals (mass, force, torque, inertia, stress, deflection), with calculations done rather than guessed.
• Pneumatics: cylinder and valve selection, circuit basics, force and speed control.
• Practical knowledge of manufacturing processes,



including what each one costs and can hold.
• Ability to read supplier catalogues and datasheets and make a justified selection.
• Comfortable on the shop floor with fitters, machinists, welders and vendors. VALUABLE TO HAVE
• Rotary indexers, bowl feeders, servo axes or robot-integrated cells.
• FEA / structural simulation, Fusion 360 CAM.
• Aluminium profile framing; stainless steel builds for food or pharma.
• Experience guiding or reviewing junior engineers.
• Awareness of machine safety standards and risk assessment. WHAT SUCCESS LOOKS LIKE
• 3 months: fluent in our standards and vendor base; owns the detailed design of a machine already in the pipeline.
• 6 months: takes a project from customer requirement to released drawings and BOM without supervision.
• 12 months: owns the mechanical scope of several concurrent projects and has measurably improved our design library and cut repeat errors between design and assembly. WHY JOIN US
• Real ownership: your machine, your decisions, from concept to the customer's floor.
• Direct work with the Director, with no layers in between.
• Growth path to Design Lead as the engineering team expands.
• Salary as per industry standards, based on skill and aptitude shown in selection. Travel and site allowances, PF, ESI/medical insurance and gratuity as applicable.
