Senior Antenna Engineer

Astranis builds advanced satellites for high orbits, expanding humanity's reach into the solar system.

As a Senior Antenna Engineer you will be responsible for the design, qualification, and procurement of antenna system components for ongoing production as well as R&D programs.

Responsibilities

• Leverage cutting-edge design tools to realize high-performance communications antenna systems with on-orbit flexibility to meet evolving customer demand.
• Work with vendors to design and procure space-qualified antenna and RF components and validate their performance through clean-room and anechoic chamber testing.
• Co-design antenna systems in conjunction with other technical disciplines including Structural/Thermal and Software-Defined Radio to achieve overall system requirements.
• Work with the sales team to propose novel antenna systems that satisfy customer needs.
• Assist in recruiting, interviewing, and hiring additional teammates to our rapidly-growing team.

Requirements

• Ability to relocate to San Francisco to work onsite as we design, integrate and test mission critical hardware.
• 5 - 15+ years of experience in relevant industry or academic roles.
• Demonstrated ability to implement high performance antenna systems in research or industry settings.
• Strong ability to collaborate with diverse engineering disciplines to collectively design and build performant RF/antenna systems, including mechanical, thermal, systems and software engineering.
• Strong antenna and microwave engineering fundamentals including theory of impedance matching, filters, combiners, amplifiers, etc.
• Experience measuring components using vector network analyzers and antenna measurement ranges, either anechoic or near field scanners.
• Demonstrated ability to solve engineering challenges in innovative and creative ways.
• Capable of using industry-standard design tools such as CST, HFSS, or TICRA and scripting to solve engineering problems using Matlab or Python.

Bonus

• Experience with digital beamforming, active feed networks, or reconfigurable antennas
• Understanding of co-site interference and antenna siting optimization
• Experience with link budget and system calculations including EIRP, noise figure, and G/T
• Experience designing waveguide components (orthomode transducers, diplexer, filters, polarizers, etc)
• Experience with deployable reflectors
• Familiarity with aerospace antenna design and test principles, including spacecraft charging, passive intermodulation, and multipaction
• Experience testing for EMI/EMC performance and understanding of mitigation practices
• Experience with integrated electronics, inclusive of beamformers, amplifiers, cooling, packaging, and interconnects
• Experience with manufacturing technologies and their impacts on RF/Antenna design, including metal additive manufacturing, CNC machining, split block, composites, electroforming, and plating

Benefits

• Base pay is just one component of Astranis's total rewards package.
• Your compensation also includes a significant equity package via incentive stock options, high-quality company-subsidized healthcare, disability and life insurance, 401(k) retirement planning, flexible PTO, and free on-site catered meals.
