Antenna Design Engineer

On-site Redwood City, CA, United States Full-time 3+ yrs
About Us
Array Labs builds advanced radar systems to help humanity understand and respond to changes across the physical world.
We're launching a coordinated fleet of radar satellites to create a high-resolution 3D map of the Earth, updated in real time, enabling faster, smarter decision-making for government and commercial organizations supporting disaster response, infrastructure resilience, and mission-critical geopolitical intelligence.
We design and build our satellites end-to-end, producing the world's most advanced earth observation satellites. Our fleet will deliver unprecedented levels of accuracy, coverage, and responsiveness to power critical insights precisely where they're needed most.

About the Job
As an Antenna Design Engineer, you will design, simulate, and validate the radiating structures and arrays used in Array’s spaceborne radar payloads. Your work will involve developing antennas with high power density, precise pattern control, and stable performance across the environmental and packaging constraints of small satellites. You will take designs from concept through EM analysis, prototyping, and qualification, working closely with RF, mechanical, thermal, and systems engineers. The antennas you develop will directly influence Array’s transmit power, imaging resolution, calibration stability, and overall radar system capability.
As part of our quickly growing engineering team, you will play a critical role in the design of the world’s most advanced radar satellite constellation—one that will significantly improve humanity’s ability to rapidly and comprehensively understand our changing planet.

Responsibilities

  • Design, simulate, and optimize antennas including patch antennas, microstrip arrays, and phase arrays.
  • Define antenna requirements and interface with spacecraft and payload subsystems to ensure integration feasibility.
  • Perform full EM simulations using tools such as HFSS, CST, and ADS.
  • Prototype and test antenna systems in lab and field environments, including range and anechoic chamber testing.
  • Support bring-up, integration, and verification of antennas in both development and flight environments.
  • Collaborate with systems engineers to evaluate link budgets and overall system performance.
  • Develop manufacturing and test procedures in collaboration with production teams.

Basic Qualifications

  • Bachelor’s degree in Electrical Engineering, Physics, or a related field.
  • 3+ years of industry or research experience in antenna or RF systems engineering.
  • Experience with antenna design, simulation, and measurement tools (e.g., HFSS, CST, ADS, MATLAB).
  • Knowledge of transmission line theory, impedance matching, and RF system design.
  • Proficiency in laboratory test equipment: vector network analyzers (VNAs), spectrum analyzers, signal generators, etc.
  • Excellent teamwork and communication skills.
  • Ability to work in a fast-paced, iterative design environment.
  • US citizen or permanent resident (green card).
