Job description

The Role

Software Test Engineer focused on validation of complex radar payloads. The role bridges hardware and software, writing firmware and Python automation to prove system performance in extreme space conditions.

Responsibilities

• Design and implement automated test frameworks in Python to characterize radar, RF, and antenna subsystems.
• Write firmware in C/C++ to stimulate hardware interfaces, inject test patterns into FPGAs, and control RF transceivers during validation.
• Develop Hardware‑in‑the‑Loop (HIL) test setups that integrate flight software, ground station commands, and simulated environmental data.
• Automate the control of laboratory test equipment (Signal Generators, Spectrum Analyzers, Network Analyzers, Oscilloscopes) to capture and analyze system performance data.
• Collaborate with FPGA and RF engineers to define test requirements and debug complex hardware‑software integration issues.
• Analyze test data to identify trends, performance regressions, and potential hardware failures before they reach orbit.
• Maintain and upgrade continuous integration (CI) pipelines that run automated tests on physical hardware targets.

Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
• 5+ years of experience in test engineering, embedded software development, or hardware validation.
• Strong proficiency in C/C++ for embedded targets (writing test firmware, drivers, or diagnostic tools).
• Expertise in Python for test automation, data analysis, and instrument control (e.g., PyVISA, NumPy, Pandas).
• Familiarity with standard communication protocols such as SPI, I2C, UART, Ethernet, and PCIe.
• Hands‑on experience with lab equipment (Oscilloscopes, VNAs, Spectrum Analyzers) and debugging hardware down to the component level.
• Excellent problem‑solving skills and the ability to work independently in a fast‑paced, startup environment.

Preferred Qualifications

• Master’s degree in an engineering discipline.
• Experience with radar systems, phased array antennas, or satellite communications.
• Experience with Xilinx Zynq/MPSoC platforms and Petalinux/Yocto build systems.
• Familiarity with continuous integration tools (Jenkins, GitLab CI) applied to hardware testing.
• Background in developing automated drivers for test equipment (Keysight, Rohde & Schwarz, Anritsu).

Compensation & Benefits

Our hiring and compensation strategy is simple: find uncommonly good people and pay them uncommonly well. Full‑time employees can choose from three compensation mixes (low, medium, or high equity) and enjoy a comprehensive benefits package including health, dental, vision, a 401(k) with company match, commuter benefits, and more.
