About the Job

Requirements

  • A bachelor's degree in Electrical Engineering, Aerospace Engineering, Computer Science, or a related field is required.
  • At least 3 years of experience in hardware validation, test engineering, or RF systems testing is required.
  • Experience designing, testing, and debugging RF printed circuit board assemblies (PCBAs), with a thorough understanding of electronics reliability and failure mechanisms, is required.
  • Experience using test equipment, including oscilloscopes, vector network analyzers (VNAs), spectrum analyzers, and signal generators, and procedures for analysis, verification, and validation of RF products is required.
  • Strong expertise in Python and C/C++ for data analysis and test automation is required.
  • Ability to conduct root-cause failure analysis and implement corrective actions, particularly for RF systems, is required.
  • A thorough understanding of metrology, sources of measurement error, and uncertainty analysis is required.
  • Ability to analyze system requirements, decompose them into verifiable test cases, and maintain bidirectional traceability using industry-standard tools such as Jira is required.
  • Ability to work in a highly cross-functional role and independently is required.
  • Strong interpersonal, verbal, and written communication skills are required.
  • Ability and willingness to thrive in a fast-paced, rapidly changing work environment is required.

Responsibilities

  • Develop and execute test, validation, and quality-assurance strategies to qualify wireless payloads, uncover weaknesses, and demonstrate that hardware can withstand radiation, thermal cycling, and mechanical stress.
  • Support the hardware lifecycle from design validation through flight readiness and volume production, helping scale reliable, mission-ready hardware for the satellite constellation.
  • Work closely with cross-functional hardware, software, and mechanical teams to ensure reliability from initial design through manufacturing and in-orbit operation.

Desired Qualifications

  • Experience with environmental testing, including thermal, vibration, and thermal vacuum (TVAC), is strongly desired.
  • Experience in high-volume manufacturing, assembly, and testing of electronic components is strongly desired.
  • Experience developing automated test systems and test fixtures for production environments is strongly desired.
  • Experience analyzing the impact of radiation on electronic components and strategies to mitigate it is strongly desired.
  • Familiarity with NASA and military specification test and workmanship standards for space hardware, such as MIL-STD-810/883 and NASA/IPC J-STD-001ES, is strongly desired.

About the Company

Hubble Network

BLE-enabled satellite communications via software updates

Hubble Network enables Bluetooth Low Energy devices to connect directly to low-Earth-orbit satellites without needing new modems or chipsets. It uses digital beamforming and phased-array antennas, allowing BLE radios to send location and sensor data through a software/firmware update, supported by a growing satellite constellation and terrestrial gateways. Unlike others that sell new radios, Hubble works by updating existing BLE devices to talk to space, delivering much lower battery use and cheaper per-device connectivity. Its goals are to grow the satellite network to about 60 satellites by 2030, expand partnerships, and lower the cost of satellite IoT connectivity for many devices.
