Senior Mechanical Design Engineer

Origin; Bengaluru; On-site; INR 1,500,000 - 3,500,000; Full time

Job summary

Origin, Bengaluru, is seeking a Senior Mechanical Design Engineer to own major subsystems of the mobile manipulator, such as the multi-axis arm, heavy-duty base, or lift column. You will ensure subsystems withstand extreme abuse while maintaining millimetre-level precision.

You will run complex structural analyses, manage packaging constraints, and lead physical validation testing, with mentoring of junior engineers in CAD, FEA, and GD&T.

Qualifications

• Bachelor's or Master's in Mechanical Engineering, Aerospace, or Robotics.
• 4–8 years of experience designing dynamic mechanical systems.
• Expert CAD skills with Onshape and PDM; GD&T (ASME Y14.5) proficiency.
• Hands-on fabrication, prototyping, and testing experience.
• Familiarity with URDFs and simulation is a plus.

Responsibilities

• Architect and detail-design core mechanical structures, castings, and weldments for the robot.
• Conduct rigorous FEA (static, fatigue, and modal) to optimise for weight, stiffness, and manufacturability.
• Design complex, high-precision mounting interfaces for high-torque actuators, LiDARs, and vision systems, ensuring zero backlash and perfect alignment.
• Lead rapid prototyping efforts to physically validate designs before committing to expensive tooling.
• Mentor junior engineers in CAD best practices, FEA setups, and GD&T application.

Job description

About Origin

Origin (previously 10xConstruction) is building general-purpose autonomous robots for US construction to tackle rising costs, safety risks, and labour shortages. Our modular, multi-trade platform combines purpose-built hardware with real-time site intelligence to navigate complex environments and execute tasks with precision. Trained in high-fidelity simulation and already deployed on live sites, our robots deliver 5x faster execution, 250%+ margin expansion, and significant cost savings. Join India's most talent-dense robotics team, consisting of individuals from IITs, Stanford, UCLA, etc.

About The Role

As a Senior Mechanical Design Engineer you will take full ownership of major subsystems of the mobile manipulator (e.g., the multi-axis robotic arm structure, the heavy-duty mobile base chassis, or the lift column). You will be responsible for ensuring your subsystems survive extreme physical abuse while maintaining millimetre-level precision. You will independently execute complex structural analyses, manage difficult packaging constraints, and lead physical validation testing.

Key Responsibilities

Subsystem Design & Analysis

• Architect and detail-design core mechanical structures, castings, and weldments for the robot
• Conduct rigorous FEA (static, fatigue, and modal) to optimise for weight, stiffness, and manufacturability
• Design complex, high-precision mounting interfaces for high-torque actuators, LiDARs, and vision systems, ensuring zero backlash and perfect alignment

V&V and Reliability Engineering

• Translate product needs into verifiable engineering requirements for your subsystems
• Develop and execute rigorous physical Verification and Validation (V&V) protocols (e.g., drop testing, vibration tables, and continuous load cycling)
• Own the DFMEA for your subsystems and implement design changes to mitigate identified failure modes

Real-to-Virtual Fidelity

• Create and maintain mathematically rigorous URDFs for your subsystems, calculating exact inertial properties, centre of mass, and friction models to feed the simulation and controls teams

Prototyping & Mentorship

• Lead rapid prototyping efforts to physically validate designs before committing to expensive tooling
• Mentor junior engineers in CAD best practices, FEA setups, and GD&T application

Required Qualifications And Skills

• Bachelor's or Master's degree in Mechanical Engineering, Aerospace, or Robotics
• 4-8 years of professional experience in designing dynamic mechanical systems
• Expert proficiency in CAD software (Onshape or equivalent) and PDM systems
• Strong background in applying GD&T (ASME Y14.5) and performing complex 3D tolerance stack-up analyses
• Deep understanding of material science, metal fabrication (machining, welding, casting), and structural mechanics
• Strong hands‑on fabrication and prototyping skills

Preferred Experiences

• Experience designing mobile robots, heavy-duty gimbals, or CNC machinery
• Practical experience writing Python or MATLAB scripts to automate kinematic or dynamic calculations
