Sr. Digital Design Engineer

Overview

Senior Digital Design Engineer role in Seattle, WA. 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 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.

Responsibilities

• Develop system architecture and RTL codebase for FPGA module focused on localization and packet decoding of BLE transmissions.
• Collaborate with cross-functional teams (system, hardware, software) to optimize throughput, accuracy, power efficiency, and reliability.
• Lead projects from concept to reality with urgency and a results-oriented approach.
• Describe and iterate requirements, support design reviews, and ensure end-to-end validation with RF and software teams.

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 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 (DDR/DDR3/DDR4) including controller integration, timing constraints, and performance tuning.
• Proficient in integrating and validating high-speed serial interfaces (LVDS, SPI, I2C, UART, SERDES-based links).
• FPGA synthesis, timing closure, and resource optimization (Xilinx or Intel/Altera).
• Experience with simulation/verification tools (ModelSim, Questa, Vivado, VUnit) and scripting (Python, Tcl).
• Strong DSP knowledge (filters, correlation, decimation, fixed-point arithmetic).
• Experience developing packet decoders for wireless protocols (BLE, ZigBee, LoRa, or custom PHYs).
• Ability to work with RF engineers, firmware developers, and systems engineers for end-to-end validation.
• Strong interpersonal and written/verbal communication skills; ability to work independently and in fast-paced environments.

Desirable

• Experience designing distributed DSP systems across multiple FPGAs or compute nodes.
• Familiarity with ARM cores, peripheral interfacing (SPI, I2C, AXI), and embedded Linux (Petalinux).
• Knowledge of synchronization techniques (preamble detection, timing recovery, frequency offset correction).
• Experience with lab tools (oscilloscopes, logic analyzers, RF test equipment).
• Knowledge of low-power design for space-based or resource-constrained systems; BLE physical layer familiarity.

Compensation & Benefits

• Salary range: $180,000 per year (base).
• Comprehensive benefits – Health, Dental, Vision, HSA options.
• Unlimited PTO; Parental Leave; Commuter Benefits; Learning & Development Allowance.
• Health & Wellness Stipend; Sabbatical Program; access to cutting-edge space tech; team retreats and more.
