About the Job

Requirements

  • At least 2 years of directly relevant experience.
  • A bachelor's degree in Electrical Engineering, Computer Engineering, or a related discipline; a master's degree is preferred.
  • Strong understanding of communication theory and signal-processing algorithm design, including channel estimation, equalization, beamforming, timing recovery, coding, and error correction.
  • Knowledge of wireless communication protocols such as 5G, LTE, WCDMA, GSM, 802.11 standards, and Bluetooth or Bluetooth Low Energy.
  • Expertise developing signal-processing and wireless communications systems, such as FSK, OFDM, and MIMO, with hands-on lab testing and characterization experience.
  • Experience with MATLAB or Python and/or C/C++ for algorithm development, modeling, and simulation.
  • Experience and knowledge of High Level Synthesis, silicon prototyping, FPGA development, and emulation systems.
  • Experience bringing up real systems in silicon, FPGA, or SoC, and using laboratory test equipment such as oscilloscopes, logic analyzers, spectrum analyzers, and signal generators.
  • Ability to work independently and learn new technologies, network protocols, and tools rapidly.
  • Availability to work extended hours and weekends when critical events require it.

Responsibilities

  • Develop and implement algorithms enabling wireless connectivity between terrestrial Bluetooth devices and satellites.
  • Contribute to modeling, system design, and implementation of wireless communications.
  • Work with cross-functional hardware and software engineering groups.
  • Lead projects from concept to completion.
  • Understand requirements flow-down and iterate on evolving system requirements.
  • Conduct self-directed design reviews and participate in reviews of parallel systems.

Desired Qualifications

  • Five to ten years of relevant experience.
  • Experience with multi-radio coexistence management.
  • Experience in modem architecture, microprocessor architecture, and hardware and software control.
  • Experience designing low-power algorithms for power-critical applications.

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.
