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.

Our Story & Mission

At SpaceX, we were part of the teams that built the largest rocket in human history, launched the largest constellation of satellites ever made, and delivered connectivity to millions of people worldwide. What we learned was simple: infrastructure is everything.

At Starbase, the biggest barrier to launching missions to Mars was not building the rocket. It was how slow, expensive, and complex it was to build the infrastructure around it. We lacked buildings, roads, water, power, communications, and waste management, and constructing them took far more time and resources than it should have.

From a first-principles perspective, that doesn't make sense. It shouldn't be this hard or costly to create the foundations for progress. That’s when we realized something important: the same engineering mindset that enabled us to tackle space exploration and mass manufacturing could be applied to infrastructure. By bringing the principles of simplification, iteration, acceleration, and automation to construction, we can unlock a new era in how the world builds.

Accelerating infrastructure unlocks progress across every domain, creating a self-sustaining engine for tackling humanity’s toughest challenges. The innovations we develop on Earth will lay the groundwork for the technologies that one day make settlement on Mars possible.

Job Overview

You will design and maintain the electrical systems that enable reliable remote operation of construction equipment. This includes wiring harnesses, circuits, and system integration for drive-by-wire machines in rugged outdoor environments. The role is hands-on, spanning fabrication, lab and field troubleshooting, and vendor collaboration to streamline builds.

Responsibilities

• Design wiring harnesses, circuits, and systems to enable safe and reliable control of drive-by-wire machinery in high vibration, dirty, outdoor environments

• Develop and maintain working relationships with manufacturers to streamline production and manufacturing of designs

• Assemble and install harnessing and circuits for development testing and use in an operational environment out in the field

• Use measurement equipment to troubleshoot electrical systems on the bench and in the field. Use the tools available to implement immediate fixes and develop sustainable long-term solutions

• Eliminate uncertainty through the use of effective documentation practices and facilitate collaboration and future development

Basic Qualifications

• B.S. in Electrical Engineering

• Practical experience working on electrical systems

Preferred Skills & Experience

• Experience building wiring harnesses and assembling circuit boards (preferably to industry or other recognized standards)

• Experience using electrical measuring equipment (oscilloscope, multimeter, signal analyzer, etc.)

• Experience designing and qualifying systems for high vibration and/or outdoor environments

• Strong understanding of "fail-safe" design principles

Additional Requirements

• Comfortable with working in a fast-paced startup environment

• Must be willing to relocate to Austin, TX if not within commuting distance

• Must be willing to work extended hours or weekends when needed to support critical deadlines

Compensation & Benefits

Base compensation will vary based on factors such as relevant experience and education. Salaries and leveling will be determined on a case-by-case basis if an offer is extended. Our total compensation package also includes equity in TerraFirma. Relocation packages are available to help cover moving costs, if applicable.
