Electromechanical Engineer

About the Company

At TerraFirma, we’re redefining how the world moves earth for construction. Founded by former SpaceX engineers and backed by Bain Capital Ventures, TerraFirma is automating construction to make it faster, cheaper, and safer.

Responsibilities

• Design mechanical systems with enclosures, actuators, linkages, mounts, and custom brackets for remote operation of heavy machinery
• Rapidly prototype and iterate using 3D printing, CNC machining, and other in-house fabrication methods
• Work with internal engineering teams, vendors, and manufacturers to ensure designs are feasible and cost-effective
• Build and test electromechanical assemblies designed to survive vibration, impact, water ingress, and outdoor exposure
• Integrate wiring harnesses with mechanically secure routing, protection, and strain relief
• Diagnose and repair mechanical and electrical components using standard tools and hands-on evaluation
• Collaborate with vendors and fabricators to produce reliable, field-ready mechanical parts and electrical components
• Maintain CAD models, mechanical drawings, and build documentation to support repeatable assembly

Requirements

• B.S. in Electromechanical, Mechanical, or Mechatronics Engineering
• Hands-on experience designing and assembling mechanical systems with actuators and sensors
• Proficient in mechanical prototyping using 3D printing, machining, and basic fabrication tools
• Familiarity with field deployment challenges like mechanical fatigue, waterproofing, and ruggedization
• Ability to collaborate across disciplines with electrical and software teams
• Willingness to work extended hours or weekends when needed
• Willingness to relocate to Austin, TX if not within commuting distance

Preferred Qualifications

• Experience designing electromechanical systems for Drones, Electric Vehicles, Aircraft, or Robotics
• Strong mechanical design of electronics enclosures for extreme environments
• Experience with motion systems including brushless DC motors, multi-bar linkages, and kinematics
• Experience with structural analysis and material selection for outdoor, high-impact environments
• Familiarity with sensor integration and motion feedback components
• Understanding of EMI shielding, thermal management, and protective enclosure design
• Experience routing wiring harnesses in mobile or vibration-prone systems
• Proficiency with CAD tools (e.g., SolidWorks, Fusion 360, Onshape)
• Strong understanding of Electrical Engineering principles and hands-on experience building electrical systems
