Digital Signal Processing Engineer

Job Title: Digital Signal Processing (DSP) Engineer
Location: Los Angeles, CA (in-person)
Job Type: Full Time (W-2)

Overview:

Half the world still doesn't have stable Internet – want to play a critical role in changing that? Beamlink builds entire cellular networks in a matter of weeks, not years. These are built of easy-to-set-up cells, called Bentocells, which address the historic bottleneck preventing carriers from expanding beyond cities. Our dynamic engineering team designs these in-house along with the firmware, software, and network architectures that make them run.

Role Description:

We are looking for a Digital Signal Processing Engineer to join our team full-time. You will work on high-speed digital systems, FPGA development, and software-defined radio (SDR) platforms powering Beamlink’s wireless networking products. This role involves designing complex digital hardware, developing FPGA-based packet processing systems, and improving signal integrity and RF system performance for next-generation telecommunications infrastructure.

Responsibilities:

• Design and collaborate on high-speed digital systems, including USB 3.0, Gigabit Ethernet, and other high-speed interfaces
• Work with electrical engineers in Altium Designer to develop complex multilayer PCB systems with high-speed routing constraints
• Develop FPGA-based systems in AMD/Xilinx Vivado, including packet processing and networking architectures
• Build and maintain embedded systems utilizing Zynq-based processors and programmable logic
• Develop Ethernet packet processing pipelines and related networking infrastructure in the FPGA fabric
• Design and debug digital interfaces, including I2C, SPI, UART, MDIO, and high-speed serial interfaces
• Measure, analyze, and improve signal integrity and system performance using industry-standard validation techniques and lab equipment
• Support bring-up, validation, and debugging of SDR and telecommunications hardware platforms
• Contribute to PCB layout efforts for complex BGA devices, including FPGAs and high-speed processors
• Work with firmware and embedded software to support hardware initialization, clocking systems, and low-level board management
• Participate in design reviews and collaborate closely with RF, embedded software, and manufacturing teams

Required Qualifications:

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related field
• Experience designing and debugging high-speed digital systems
• Experience with FPGA development using AMD/Xilinx Vivado tools
• Experience with FPGA-based Ethernet switching, packet acceleration, or DSP pipelines
• Familiarity with Zynq processors and FPGA-based embedded systems
• Understanding of signal integrity, impedance control, differential pair routing, and high-speed PCB design principles
• Experience with Ethernet systems and digital communication protocols
• Ability to debug hardware systems using oscilloscopes, logic analyzers, VNAs, and related lab equipment
• Familiarity with clock distribution systems, PLLs, jitter analysis, and synchronization architectures
• Basic firmware and software development skills in C, Python, or related languages
• Strong analytical and troubleshooting skills for complex embedded systems

Additional Preferred Qualifications:

• Experience designing SDR platforms or telecommunications hardware
• Familiarity with LTE, 5G-NR, or wireless communication systems
• Experience with complex BGA escape routing and multilayer PCB stack-up design
• Experience writing low-level firmware for interfaces such as I2C and SPI
• Experience with RF system integration and mixed-signal hardware design
• Exposure to production testing, manufacturing validation, or compliance testing workflows
• Experience working in a startup or rapid product development environment

Salary/Benefits:

• Salary: Competitive, commensurate with experience
• Stock options
• Health, Dental, and Vision Insurance (free)
• Life and Disability Insurance (free)
• 401k benefits
• Flexible work schedule, including the ability to work from home on certain days
• Unlimited paid time off
• Additional commuter stipend if Uber/Lyft is required to reach the office
• Opportunity for growth as the company and production function scale
