Our fleet will deliver unprecedented levels of accuracy, coverage, and responsiveness to power critical insights precisely where they're needed most.\r\nThe Role\r\nWe are looking for a Software Test Engineer to own the validation of our complex radar payload. In this role, you will bridge the gap between hardware and software, writing the code that proves our system works. You will develop specialized firmware to exercise our FPGAs, RF front-ends, and antenna arrays, while simultaneously building high-level Python automation to orchestrate test campaigns. You will work in a hands-on lab environment, pushing our hardware to its limits to ensure it survives and performs in the extreme conditions of space.\r\nResponsibilities\r\nDesign and implement automated test frameworks in Python to characterize the performance of radar, RF, and antenna subsystems.\r\nWrite firmware in C/C++ to stimulate hardware interfaces, inject test patterns into FPGAs, and control RF transceivers during validation.\r\nDevelop Hardware-in-the-Loop (HIL) test setups that integrate flight software, ground station commands, and simulated environmental data.\r\nAutomate the control of laboratory test equipment (Signal Generators, Spectrum Analyzers, Network Analyzers, Oscilloscopes) to capture and analyze system performance data.\r\nCollaborate with FPGA and RF engineers to define test requirements and debug complex hardware-software integration issues.\r\nAnalyze test data to identify trends, performance regressions, and potential hardware failures before they reach orbit.\r\nMaintain and upgrade continuous integration (CI) pipelines that run automated tests on physical hardware targets.\r\nBasic Qualifications\r\nBachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.\r\n5+ years of experience in test engineering, embedded software development, or hardware validation.\r\nStrong proficiency in C/C++ for embedded targets (writing test firmware, drivers, or diagnostic tools).\r\nExpertise in Python for test automation, data analysis, and instrument control (e.g., PyVISA, NumPy, Pandas).\r\nFamiliarity with standard communication protocols such as SPI, I2C, UART, Ethernet, and PCIe.\r\nHands-on experience with lab equipment (Oscilloscopes, VNAs, Spectrum Analyzers) and debugging hardware down to the component level.\r\nExcellent problem-solving skills and the ability to work independently in a fast-paced, startup environment.\r\nPreferred Skills & Experience\r\nMaster's degree in an engineering discipline.\r\nExperience with radar systems, phased array antennas, or satellite communications.\r\nExperience with Xilinx Zynq/MPSoC platforms and Petalinux/Yocto build systems.\r\nFamiliarity with continuous integration tools (Jenkins, GitLab CI) applied to hardware testing.\r\nBackground in developing automated drivers for test equipment (Keysight, Rohde & Schwarz, Anritsu).\r\n$150,000 - $250,000 a year\r\nCompensation & Benefits\r\nOur hiring and compensation strategy is simple: find uncommonly good people and pay them uncommonly well.\r\nWe offer high flexibility between salary and equity-based compensation. Final candidates can choose from three compensation mixes: low, medium, or high equity. Equity is a significant component of total compensation, and we aim to provide meaningful ownership for this role.\r\nFull-time employees also enjoy a comprehensive benefits package including health, dental, vision, a 401(k) with company match, commuter benefits, and more.\r\nInterview Process\r\nWe will conduct interviews via Google Meet with the potential for an onsite visit; the typical process takes around 3-5 weeks to complete from start to finish.\r\nWhy Join Array\r\nAt Array Labs, deep technical expertise meets relentless impact.
