About the Job

Requirements

A bachelor's degree in Electrical Engineering, Optical Engineering, or a related technical discipline.
At least 5 years of experience in the optical communications field.
Expertise in hardware description language development using VHDL or Verilog.
Experience with high-speed digital design, timing closure, and parallel data-path architectures.
Familiarity with AXI4 and AXI-Stream interface standards.
Proficiency with Xilinx (Vivado) and Intel/Altera (Quartus) FPGA toolchains.
Experience with FPGA clocking resources (PLL, MMCM) and multi-clock-domain integration.
Strong understanding of digital logic, state machines, pipelining, and data-path design.
Ability to create and maintain self-checking testbenches for module-level and system-level verification.
Hands-on experience with laboratory debugging and FPGA hardware bring-up.

Responsibilities

Develop, implement, and optimize FPGA designs using VHDL or Verilog.
Perform high-speed digital integration, including multi-clock-domain interfaces, timing closure, and advanced clock-constraint management.
Architect FPGA data paths emphasizing throughput, parallelism, and resource efficiency.
Implement and integrate AXI4/AXI-Stream interfaces and related on-chip bus architectures.
Design and manage FPGA clocking using PLL and MMCM primitives.
Use Xilinx and Intel/Altera FPGA tools for synthesis, place-and-route, constraint definition, and timing analysis.
Build self-checking testbenches for functional verification and regression coverage.
Debug FPGA designs in the laboratory using logic analyzers, oscilloscopes, and FPGA debug tools such as Chipscope or SignalTap.
Collaborate with DSP, systems, and software teams to define hardware architectures and support algorithm implementation.

We are seeking a highly skilled FPGA Engineer to design, implement, verify, and integrate high-performance digital logic for advanced communication and processing systems as part of Impulse’s next generation of space vehicles. The ideal candidate will have strong HDL development experience, practical understanding of high-speed digital architectures, and hands-on lab debugging skills.

About the Company

Impulse Space

In-space propulsion and payload mobility

Impulse Space builds in-space mobility services and propulsion to move payloads after launch. Its products include Mira for precise maneuvering and rendezvous, Helios high-energy kick stage, Caravan rideshare to higher-energy orbits, and propulsion lines Saiph, Deneb, and Rigel. These tools act as in-space tugs and stages to push, dock, and deploy payloads in orbit. Led by SpaceX veteran Tom Mueller, Impulse Space uses flight-proven hardware and a growing network of facilities to make reaching higher-energy orbits faster and cheaper, expanding access for customers.
