Get AI-powered advice on this job and more exclusive features.

Hubble Network was founded with the intention of delivering on the promise of what Internet-of-Things (IoT) was supposed to be. We're building a global Bluetooth network dedicated to machine-to-machine connectivity. We differentiate ourselves as the first modem-less and gateway-less, direct-to-satellite network from off-the-shelf BLE chips. Hubble is ideal for applications in logistics, AgTech, and maritime where economies of scale for volume consumer and enterprise asset tracking is a priority. Our goal is to be the first billion-endpoint-connected network in the world.

Hubble is an early-stage, venture-backed startup supported by some of the best investors in the world. In their previous lives, the founding team has been successful in raising $100s of millions in venture funding, developing the Amazon Sidewalk network, launching billions of dollars of space assets, and leading their teams to successful exits, both through acquisition and IPO. We are now looking to bring on talented team members who are the best at what they do to help us make Hubble a reality for the world.

As a Senior Digital Design Engineer, you will play a key role in developing the system architecture and RTL codebase for the FPGA module that performs localization and decodes packets from decoding from ground-based BLE device transmissions. You'll collaborate closely with a cross-functional team of system, hardware, and software engineers to optimize the throughput, accuracy, power efficiency, and reliability of the Hubble satellite constellation.

This is a full-time position based in Seattle, WA.

AN IDEAL CANDIDATE HAS

• A Sense of Urgency: Lead projects from concept to reality, rapidly and effectively
• First Principles Engineering: Have a strong understanding of the whys behind the whats; have the ability to extrapolate from first principles to complex system design
• High Learning Agility: Love to learn; have a grounded approach to recognizing your weaknesses and take the initiative to brush up on and sharpen your engineering foundations to better collaborate with your teammates with different backgrounds
• System-Level Design and Analysis: Understand the requirements flow down process and be able to quickly iterate on evolving requirements
• Excellent Communication Skills: Effectively convey ideas and communicate technical topics with engineering, build team, and operations; run self-directed design reviews and participate in reviews of parallel systems
• Anticipation of Needs: Identify problems, think creatively, and rapidly produce reliable and cost-effective solutions to meet the ever growing and changing needs of an early-stage company
  
  

BASIC QUALIFICATIONS

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or a related field.
• 5+ years of experience in FPGA-based digital design, with a strong emphasis on real-time signal processing and communication systems.
• Proven expertise in RTL design (Verilog/SystemVerilog) for high-throughput, low-latency digital receivers.
• Experience with high-speed memory interfaces, particularly DDR/DDR3/DDR4, including controller integration, timing constraints, and performance tuning.
• Proficient in integrating and validating high-speed serial interfaces such as LVDS, SPI, I2C, UART, and SERDES-based links (e.g., JESD204, PCIe, Ethernet).
• Skilled in FPGA synthesis, timing closure, and resource optimization on platforms such as Xilinx or Intel/Altera.
• Proficiency with simulation and verification tools (e.g., ModelSim, Questa, Vivado, VUnit) and scripting languages (Python, Tcl).
• Deep understanding of digital signal processing (DSP) principles, including filtering, correlation, decimation, and fixed-point arithmetic.
• Experience developing packet decoders for wireless communication protocols (e.g., BLE, ZigBee, LoRa, custom PHYs).
• Ability to work closely with RF engineers, firmware developers, and systems engineers to integrate and validate end-to-end communication chains.
• Demonstrated ability to work in a highly cross-functional role.
• Ability to work independently.
• Strong interpersonal, verbal and written communication skills is a must.
• Ability and willingness to thrive in a fast-paced, rapidly changing work environment.
• Passion for creating state-of-the-art hardware systems.
  
  

STRONGLY DESIRED

• Experience designing distributed digital signal processing systems across multiple FPGAs or compute nodes.
• Familiarity with soft-core or hard-core processor integration (e.g., ARM) and peripheral interfacing (SPI, I2C, AXI).
• Embedded linux (Petalinux) experience.
• Familiarity with synchronization techniques (e.g., preamble detection, symbol timing recovery, frequency offset correction).
• Experience working 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.
• Familiarity with BLE physical layer characteristics or similar short-range RF communication standards.
