OverviewWe're looking for an
RF Electrical Engineer to take ownership of our spacecraft's TT&C (Telemetry, Tracking & Command) radios - the S-Band link that keeps our satellites talking to the ground.
You'll own this subsystem end to end: architecture, link budgets, PCB design, and the antenna interface, built to survive the harshest environment there is. This is a hands-on, cross-disciplinary role working directly with electrical, systems, mechanical, and software engineers to ship a critical piece of hardware that flies.
What You'll Own:- End-to-end design of the satellite's S-Band radio - schematic capture, PCB layout, and component selection, in close coordination with antenna design engineers
- Spacecraft radio link budgets across all mission phases
- EMI/EMC compliance and spaceflight reliability across the design
- Electrical and RF test/validation at unit, subsystem, and system level
- Hardware bring-up, debugging, and performance tuning in lab and flight environments
What You Bring:- B.S. in Electrical Engineering or related field (M.S. a plus)
- Hands-on experience with RF/electrical engineering, including PCB design with RF layout and routing
- Proficiency with RF/EM tools: HFSS, ADS, or MATLAB
- Working knowledge of EMI/EMC standards and practices (e.g., MIL-STD-461)
- Experience with digital interfaces relevant to radio integration (UART, SPI, I2C, Ethernet)
- Hands-on lab experience: oscilloscopes, network analyzers, signal generators
- Strong documentation habits and cross-functional communication
Strongly Preferred:- Experience designing RF/electronics for space or spacecraft systems
- Exposure to radiation-tolerant component selection and thermal/vacuum design constraints
