## About the Role

Robotics, Computer Engineering, Robotics, Machine Learning, Economics, Product Design, Prototyping, Requirements Management, Test Suite, Computer Engineering, * Experience taking mechanical designs or systems through fabrication, testing, and real-world deployment, with examples you can discuss

 * Proficiency in one or more mechanical CAD tools, with a strong understanding of tolerancing, material selection, and manufacturing processes
 * Practical understanding of loading, stiffness, friction, deformation, material properties, environmental effects, and other fundamentals, with experience applying that knowledge and making tradeoffs to meet design requirements
 * Confidence building and modifying prototypes
 * The ability to define an engineering problem, drive changes with concrete data, and produce effective solutions, * Experience in robot integration, mechanism design, actuator mechanics, mechanical interfaces, gearboxes, arm kinematics, or end effectors
 * High-volume manufacturing experience, process development, or experience designing for scale production
 * GD&T fundamentals

## Description

As a Robotics Hardware Engineer you will design and build the mechanical systems behind Ixian's robots. You will take extreme ownership of your hardware, from design requirements through concept design, prototyping, test suite design, design for manufacturing, and reliable field performance. The scope of work spans mechanism design, actuation, structural component design, electronics integration, and field deployment.

You will be the responsible engineer for all of the hardware you produce. Every engineering decision must be reasoned from physics first principles and communicated effectively to the team. A strong analytical background is required, but your approach to problem solving must be pragmatic, grounded, and rapid. When failures occur or requirements change, you must be able to iterate or pivot quickly.

WHAT YOU'LL DO

 * Design mechanical parts and assemblies in CAD, with dimensioned drawings and well-reasoned tolerance stackups
 * Select and design for the tradeoffs of various manufacturing processes such as 3D printing, CNC machining, sheet metal forming, and injection molding
 * Select and size actuators, bearings, power transmission components, and other off-the-shelf hardware for load, speed, precision, and lifespan requirements
 * Fabricate and assemble prototypes and create assembly work instructions
 * Collaborate with electrical engineers, software engineers, and operations leads; mechanically integrate sensors, electronics, and cabling
 * Build test fixtures and create calibration procedures; measure stiffness, repeatability, wear, and thermal performance; predict fatigue and mechanical failure of components
 * Work with suppliers on manufacturability, maintain bills of materials, and clearly document designs
