Principal ASIC Design Engineer


Principal ASIC Design Engineer

Irvine, CA
  • Responsibilities

    SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.



    This is a principal digital ASIC design role in the development of broadband satellite modem hardware solutions. This position includes significant responsibilities in one or more of the following areas: requirements and specifications, micro-architectural definition, digital design (RTL) and verification, synthesis, static timing analysis, and power estimation and optimization. Project deliverables may include specification documents, micro-architecture designs, RTL code, simulation models, test benches, gate-level netlists, timing constraints, UPF files, and associated documentation and additional collateral.

    As a principal digital ASIC designer, you will be responsible for all aspects of digital ASIC design focusing on RTL design, verification, logic synthesis, and timing analysis. You will design digital signal processing (DSP) data paths and control systems for advanced mixed analog/digital integrated circuits in System Verilog.

    Job functions also include verification and debugging for digital modules through simulation, and development of functional test cases. Design optimization and tradeoffs for balancing performance, power, and area is required.


    • RTL design of digital circuits using hardware description languages such as Verilog and System Verilog.
    • Logic synthesis using Synopsys Design Compiler.
    • Estimating and scheduling your work so that progress can be managed by our in-house program management group.
    • Documenting High level description of designs and requirements for signal processing subsystems.
    • Writing functional test cases to verify and debug digital designs.
    • Writing scripts using languages such as Tcl and PERL to achieve higher performance and improve productivity through automation.
