About the Job

Requirements

  • Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or a related field.
  • 10+ years of experience across wireless systems and/or FPGA-based digital design, including 3+ years leading or managing engineering teams.
  • Strong understanding of communication theory and digital signal processing, including filtering, correlation, decimation, channel estimation, beamforming, timing recovery, coding and error correction, and fixed-point arithmetic.
  • Experience with MATLAB or Python and/or C/C++ for algorithm development, modeling, and simulation, plus simulation and verification tools such as ModelSim, Questa, and Vivado, and scripting with Python and Tcl.
  • Experience developing packet decoders for wireless communication protocols such as BLE, ZigBee, LoRa, or custom physical layers.
  • Experience designing localization or geolocation algorithms such as Doppler-based positioning, TDOA/FDOA, angle-of-arrival, or Kalman/particle filtering for position estimation.
  • Proven expertise overseeing RTL design using Verilog/SystemVerilog for high-throughput, low-latency digital receivers.
  • Skill in FPGA synthesis, timing closure, and resource optimization on Xilinx or Intel/Altera platforms.
  • Familiarity with high-speed memory interfaces such as DDR/DDR3/DDR4 and high-speed serial interfaces including LVDS, SPI, I2C, UART, and SERDES-based links such as JESD204, PCIe, and Ethernet.
  • Demonstrated ability to lead technical teams by setting direction, mentoring engineers, running design reviews, and delivering against evolving requirements.
  • Ability to work closely with RF engineers, firmware developers, and systems engineers to integrate and validate end-to-end communication chains.
  • Strong interpersonal, verbal, and written communication skills.
  • Ability and willingness to thrive in a fast-paced, rapidly changing work environment.
  • All applicants must be a U.S. citizen or lawful permanent resident as defined by ITAR.

Responsibilities

  • Lead the design of Hubble's wireless communication and localization systems and own their implementation in HDL on satellite FPGAs.
  • Provide senior-level wireless systems expertise in modeling, algorithm design, and system architecture for direct-to-satellite Bluetooth connectivity and geolocation.
  • Manage and grow the team of digital design engineers responsible for flight-ready FPGA implementations.
  • Define the algorithms and protocols that connect terrestrial Bluetooth devices to satellites and determine their position from orbit.
  • Direct the digital design team responsible for the RTL codebase that performs localization and decodes packets from ground-based BLE transmissions.
  • Work closely with leaders across hardware, firmware, software, and customer success to translate strategic goals into product plans and deliverables.

Desired Qualifications

  • 15+ years of directly relevant experience.
  • Prior experience managing digital design or FPGA teams.
  • Experience with satellite-based geolocation or positioning systems, such as Doppler geolocation from LEO.
  • Experience designing distributed digital signal processing systems across multiple FPGAs or compute nodes.
  • Familiarity with soft-core or hard-core processor integration, such as ARM, and peripheral interfacing including SPI, I2C, and AXI; embedded Linux (PetaLinux) experience.
  • Familiarity with synchronization techniques including preamble detection, symbol timing recovery, and frequency offset correction.
  • Experience with multi-radio coexistence management in a BLE and satellite-link environment.
  • Experience with lab tools such as oscilloscopes, logic analyzers, and RF test equipment for bring-up and debugging.
  • Knowledge of low-power design techniques for space-based or resource-constrained systems.

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.
