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 RF Test Engineer, you will develop the hardware, procedures, and automated test infrastructure used to validate Array’s radar payloads and satellite electronics. Your work will include designing test fixtures and harnesses, creating FPGA- and software-driven test interfaces, developing board- and system-level test plans, and executing environmental and functional testing across a range of operating conditions. You will collaborate closely with electrical, RF, antenna, mechanical, and manufacturing engineers to diagnose issues, validate performance, and ensure flight readiness. The test systems you build will directly affect hardware reliability, calibration stability, and overall system performance on orbit.

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.

Develop RF and high-speed measurement solutions for in-house developed payload and avionics hardware which will fly to space

Characterize RF components and subsystems, such as LNAs, PAs, mixers, synthesizers, filters, transceivers, and antenna array assemblies

Design RF test fixtures, harnesses, and calibration/de-embedding methods that establish a trusted reference plane

Bring up and debug new RF and high-speed subsystems and testbeds with responsible engineers

Quantify measurement uncertainty and use it to set test limits

Execute functional and environmental RF testing (thermal, vacuum/TVAC, vibration), analyze test data, and provide recommendations for improvements

Validate that RF hardware meets its performance requirements, supporting acceptance and qualification campaigns and flight-readiness decisions

Participate in design reviews and provide input on testability and measurability

Maintain and calibrate RF test equipment and facilities

BS in Electrical Engineering, Physics or related STEM field with at least 2 years of related experience

Proficient working in the lab with RF test equipment, including vector network analyzers, spectrum analyzers, signal generators, power meters, oscilloscopes, and logic analyzers

Strong grasp of RF fundamentals: S-parameters, impedance matching, gain, compression, noise figure, phase noise, intermodulation, and link budgets

Working knowledge of calibration, de-embedding, fixture removal, and the sources of measurement error and how to mitigate them

Proficiency with programming and automation/scripting languages or ability to quickly learn them (i.e. Python, C++, MATLAB) for instrument control and data analysis, and navigating Linux terminals and file systems

Familiarity with design tools for schematic capture and reading RF/analog schematics

Strong technical documentation skills, including report writing and test result documentation and storage

Familiarity with software defined radios

Experience analyzing circuits and developing functional test plans

Board rework experience, specifically surface-mount soldering & hot-air rework

Experience operating in a contamination- and ESD-sensitive environments

Embedded software expertise, bare-metal (no-OS), RTOS-based, and Hardware Abstraction Layer (HAL) libraries for ARM-based microcontrollers or SoCs

Experience with system verification and validation, experience in root-cause test failures to ensure issues are understood and develop and implement mitigations as part of a process of continuous improvement

Bring-up and test of RF, power, and electronics subassemblies

Basic knowledge of RF system architecture and impairments or hands-on experience working with RF circuits and RF test equipment

Experience in space systems and environmental testing such as vibration, shock, thermal, burn-in, and TVAC

Understanding of sources of measurement error and how to implement appropriate mitigation strategies
