Senior Mechanical Design Engineer

Role Overview :

Unibose Technology Private Limited, Asia’s pioneer in ATEX Zone-0 certified No-Man Entry Robotic (NMER) systems, is looking for a seasoned Senior Mechanical Design Engineer to lead the development of next-generation robotic solutions for cleaning and inspection of industrial tanks and confined spaces across oil & gas, petrochemical, and pharmaceutical sectors.

You will own the complete mechanical design of highly reliable, explosion-proof robots capable of operating in diverse tank geometries and the harshest hazardous environments. This is a hands-on leadership role that combines deep technical expertise in 3D CAD, hydraulics & pneumatics, project execution, and cross-functional collaboration to deliver safe, field-proven robotic systems that eliminate human entry into dangerous confined spaces.

Key Responsibilities :

• Lead end-to-end mechanical design of NMER platforms — robotic arms, chassis, track / wheeled mobility systems, hydraulic & pneumatic actuators, toolings, and integration with inspection payloads.
• Develop and optimize explosion-proof (ATEX / IECEx Zone-0) 3D models, assemblies, and manufacturing drawings using SolidWorks and AutoCAD .
• Perform design calculations, FEA simulations, material selection (corrosion-resistant & spark-proof), GD&T, and tolerance stack-up analysis .
• Drive design reviews, DFMEA, and compliance with ATEX , ASME, ISO, and industry-specific standards.
• Work closely with electrical, software, manufacturing, and testing teams to take designs from concept through prototyping, field trials, and series production.
• Coordinate with vendors and shop floor for CNC machining, welding, surface treatment, jigs & fixtures, and assembly processes.
• Mentor junior engineers and ensure best design practices are followed.
• Act as the technical interface with clients — present designs, justify solutions, and incorporate feedback.
• Troubleshoot and resolve mechanical issues during prototype testing and field deployments.
• Continuously improve designs for reliability, serviceability, weight optimization, and cost.

Required Skills and Experience :

B.E. / B.Tech / M.Tech in Mechanical Engineering or related field.

Minimum 6 years of hands-on mechanical design experience, with at least 3 years in hydraulics, pneumatics, and robotics / automation (senior or lead role preferred).

Proven portfolio of designing hydraulic & pneumatic systems and robust mechanical assemblies for industrial machinery or robots.

Full product development cycle experience — concept to certified production — preferably in hazardous or confined-space applications.

Strong knowledge of manufacturing processes (CNC machining, sheet metal, welding, jigs & fixtures).

Essential Skills :

Expert in SolidWorks (advanced modeling, simulation, PDM) and AutoCAD.

In-depth understanding of kinematics, dynamics, fluid power, strength of materials, and explosion-proof design principles.

Proficient in FEA tools (SolidWorks Simulation / ANSYS), GD&T, tolerance analysis, and Design for Manufacturing (DFM).

Excellent verbal & written communication — capable of presenting to clients and leadership.

Strong project management, problem-solving, and leadership abilities.

Attention to detail with a passion for safety, quality, and field reliability.
