Astranis builds advanced satellites for high orbits, expanding humanity's reach into the solar system. Today, Astranis satellites provide dedicated, secure networks to highly sophisticated customers across the globe – large enterprises, sovereign governments, and the US military.
As a Senior RF/Communication Systems Engineer at Astranis, you will be responsible for the architecture, design, and modeling of our satellites' communication payloads. You will work closely with many other teams, including the antenna, SDR, RF, DSP, and mechanical teams, to design the best possible radio systems.
Responsibilities:
- Own architectural trade studies and establish system and unit level requirements analytically or via simulation
- Lead R&D efforts for new radio features, technologies, and custom components
- Work closely with many design teams, including RF, Antenna, digital hardware, FPGA, mechanical, and thermal
- Design and test communications-related signal processing algorithms
- Assist in recruiting, interviewing, and hiring additional teammates to our rapidly growing team
Requirements:
- Bachelor of Science degree in electrical engineering or equivalent
- 7+ years of experience
- Strong technical communication skills (oral and written)
- Strong fundamentals in signals and systems and digital communications
- Familiarity with hardware components and their associated impairments/limitations
- Comfortable working in the lab, testing radio hardware, using signal generators, signal analyzers, network analyzers, oscilloscopes, etc.
- Proven ability to triage and debug issues discovered in testing
- Comfortable developing software (Python and some C/C++)
- Fast learner of new tools and workflows
- Passion for working in a fast-paced environment and constantly learning
- RF system design and budgeting
Bonus skills:
- Familiarity with satellite radio systems (ground segment and/or space segment)
- Radio characterization test planning, automation, and execution
- Comfortable with software, especially Python, git, and GNU Radio
- Fixed-point implementation of signal processing algorithms
