Senior Mechanical Engineer - Mobile Manipulator Design (MOMA)

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 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 millimeter-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 optimize 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, 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, center 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.

Requirements

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.

Benefits

Gain experience in a dynamic startup environment at the forefront of robotics and AI innovation.

Contribute to the development of technology that will revolutionize the construction industry.

Work alongside a talented and passionate team committed to making a real-world impact.

Learn from experienced professionals and gain valuable skills in robotics software engineering.

Gain practical experience in a real-world engineering environment.

Contribute to a project with the potential to make a significant impact on the construction industry.
