Company Overview:

We invented a new approach to design, build, and fly our own rockets, starting with Terran 1 – the world’s first entirely 3D printed rocket and Terran R our reusable next generation 3D printed rocket.

Using our vertically integrated technology platform, leveraging additive manufacturing, artificial intelligence, and autonomous robotics to deliver superiority over traditional aerospace manufacturing methods, we’re disrupting 60 years of aerospace with our novelty approach to get to space, Mars, and beyond faster, more cost-effective, and more reliable.

We believe in a future where interplanetary life fundamentally expands the possibilities for human experience. Our long-term vision is to upgrade humanity’s industrial base on Earth and on Mars.


The Avionics team is responsible for the design, testing, and production of electronic on the Terran 1 and Terran R launch vehicles. As a member of this team, you will be responsible for avionics hardware designs that work with multiple vehicle systems including but not limited to vehicle sensors, propulsion, computing, actuation, energy management, and communications. Avionics operation is critical to the successful flight of Terran 1, the world’s first 3D printed rocket.

What you’ll do:

  • Drive architecture, design, and development of mixed signal electronics that will support the launch vehicle needs
  • Drive electronics hardware through the full product lifecycle including circuit design and analysis, schematic capture, layout, prototyping, bring-up, troubleshooting, issue tracking, design verification, acceptance and qualification testing, and handoff to vehicle integration
  • Work with partner teams such as propulsion, GNC, mechanisms, launch, etc. to define system requirements, interfaces, and understand system performance impacts of avionics designs
  • Make complex technical decisions (risk tradeoffs, evaluation of trade studies, anomaly investigations, etc.)
  • Support product life cycle from design to manufacturing

What you need to know:

  • Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related field
  • 1+ years of experience inmixed-signal circuit design such as amplifiers, filters, analog to digital and digital to analog converters, I2C, Ethernet, SPI, and processors
  • Familiarity with eCAD software such as Altium or equivalent
  • Experience with hardware bring-up, validation, debugging, and data analysis
  • Experience with board-level design from concept to manufacturing
  • Ability to communicate deeply technical topics to a wide variety of audiences
  • Experience working with highly cross-functional teams (mechanical, thermal, electrical, software, etc.) to develop integrated electronics solutions
  • Comfortable with working in a fast paced and autonomously driven startup atmosphere

Nice to haves but not required:

  • Knowledge in power supply components, memory interfaces, FPGAs, ASICs
  • Low-noise analog signal conditioning and sensor interface design
  • Experience with simulation software such as LTspice, MATLAB, or other
  • Experience with design of electronics for harsh environments (vibe, thermal, vacuum, radiation, etc.)
  • Experience with design of electronics for mission-critical applications (aviation, automotive, robotics, spacecraft, medical)
  • Experience with system architecture development for complex electronics systems
  • Full life cycle development of new hardware systems
