RF/Communication Systems Engineer

RF/Communication Systems Engineer

As a 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 but not limited to the antenna, SDR, RF, DSP, and mechanical teams in order to design the best possible radio systems.

Role

• Own architectural trade studies, and establish system and unit level requirements analytically or via simulation
• Lead R&D efforts for new radio features / technologies / custom components
• Work closely with many design teams, including RF, Antenna, digital hardware, FPGA, mechanical, thermal
• Communications related signal processing algorithm design and test
• Assist in recruiting, interviewing, and hiring additional teammates to our rapidly-growing team.

Requirements

• Bachelor of Science degree: in electrical engineering or equivalent
• 3+ years: of experience
• Strong technical communication skills: (oral and written)
• Strong fundamentals: in "signals and systems" and digital communications
• Familiar with: hardware components and their associated impairments / limitations
• Comfortable working: in the lab, testing radio hardware, using signal generator, signal analyzer, network analyzer, oscilloscope, etc
• Proven ability: to triage and debug issues discovered in testing
• Comfortable developing software: (Python, and some C/C++)
• Fast to learn: new tools and workflows
• A passion: for working in a fast-paced environment and constantly learning
• Don't meet them all? Not a problem. Please apply even if you do not meet all these criteria.

Bonus

• Familiarity: with satellite radio systems (ground segment and/or space segment)
• RF system design: and budgeting
• Radio characterization: test planning, automation and execution
• Comfortable with software: especially Python, git, GNU Radio
• Fixed point implementation: of signal processing algorithms
• Familiarity with: multi-rate signal processing techniques (polyphase filters, resamplers, etc)
• Multi-antenna systems: (beamforming, null-steering)
• Direct sequence spread spectrum: (DSSS) modem design
• Familiarity with: satellite waveforms and modems (DVB-S2/x, DVB-RCS2)
