About the role
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.
