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)

As an RF systems engineer on the team, you'll be responsible for defining the RF systems roadmap, trades, technology incubation and driving RF sub-systems budgets and requirements, modeling for the commercial and USG satellites payload and TT&C systems. You'll take ownership of the full lifecycle for your ideas and work collaboratively with engineers across the organization to develop creative and innovative solutions that will push the envelope of satellite technology.

Role

• System budgeting of gain, noise, linearity, distortion, interference, capacity (link budgeting)
• Test planning and execution at the integrated system level as well as board level
• Involved in architectural trades and a range of design decisions all the way down the the the component/circuit level
• Assist in recruiting, interviewing, and hiring additional teammates to our rapidly-growing team.

Requirements

• Familiar with software development (Python, and some C/C++), and fast to learn new tools
• RF system level design and budgeting
• RF testing and test design
• Highly organized and process oriented
• Strong technical communication skills (oral and written)
• Familiar with analog/RF components and associated impairments
• Bachelor of Science degree in electrical engineering or equivalent
• 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.
• 2+ years of RF engineering experience or equivalent

Bonus

• Familiarity with satellite radio systems (ground segment and/or space segment)
• Comfortable with software, especially Python, git
• Experience designing RF hardware
• Familiarity with satellite waveforms and modems (DVB-S2/x, DVB-RCS2)
