Senior Power Electronics Engineer

Company Overview:  

Relativity is the first and only company to automate aerospace manufacturing by integrating intelligent robotics, software, and proprietary metal 3D printing technology. Disrupting 60 years of aerospace, Relativity offers a radically simplified supply chain, building a rocket with 100x fewer parts in less than 60 days. Our long-term goal is to upgrade humanity’s industrial base on Earth and on Mars.  

Team:

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 in power circuit design such as DC-DC converters, hotswap controllers, battery
management system, and LDOs
• 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 have but not required:
• Knowledge in thermal design, topologies, modulation schemes, control strategies for converters
• Understanding how magnetics (inductors, transformers), semiconductors (MOSFET, GaN FET), and
capacitors (Electrolytic, film and Ceramic) are used for power conversion
• Experience with simulation software such as LTspice, MATLAB, or other
• Experience with design of electronics for harsh environments (vibe, thermal, vacuum, radiation, etc.) 

Relativity Space offers competitive salary and equity, a generous vacation policy, an annual L&D stipend and more!
