Overview

Profile match
CesiumAstro is an American company founded in Austin in 2017 that builds active phased array communications payloads for satellites, aircraft and defence platforms. Its systems are software-defined and electronically steered, which lets a moving platform track several links at once without mechanical antennas, and the company manufactures them in house rather than integrating third-party subsystems. It sells mainly to defence customers and satellite operators, has raised venture funding from investors including Airbus Ventures and Lightspeed, and operates facilities in Austin, Colorado and the United Kingdom.

We are looking to add an FPGA Verification Engineer II to our team. If you enjoy working in a startup environment and are passionate about developing leading-edge phased arrays for satellites, spacecraft, and aerospace systems, we would like to hear from you.

JOB DUTIES AND RESPONSIBILITIES

  • Contribute to the evaluation and technical implementation of FPGA and digital design simulation, verification and emulation infrastructure.
  • Contribute to the development, maintenance and phased deployment of continuous integration and regression testing infrastructure.
  • Develop state-of-the-art UVMf-based top-level and module-level testbenches using block-to-top best practices for reusability, including both control and data plane stimulation using VIP & System Verilog DPI-C integration with existing MATLAB and Python numerical models.
  • Lead the development of reusable custom VIP modules.
  • Work closely with the engineering and senior leadership teams to train and mentor engineers at all experience levels on UVMf testbench usage and modern approaches to FPGA/digital design. Work with the modeling and scientific staff to implement DPI-C dataplane verification interfaces into existing MATLAB and Python models.
  • Aid the Lead Verification Engineer in evaluating current processes regarding FPGA and digital design with a focus on Xilinx TLM models and QEMU-RP integration.
  • Work closely with vendors to define requirements of future simulation model deliverables.
  • Maintain up-to-date knowledge of industry best-practices regarding FPGA and digital design methodologies.
  • Work closely with the engineering leadership team to evaluate and non-disruptively implement process improvements.

JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS

  • A Bachelor of Science (BS) or Master of Science (MS) degree in Computer Science, Electrical Engineering, or Computer Engineering.
  • Minimum of 2 years of industry experience in verification and automation.
  • Knowledge of FPGA digital design verification techniques including VHDL, Verilog, SystemVerilog, C/C++, SystemC, UVM/UVMf, DPI-C, TLM, Formal CDC and functional analysis, QEMU and VIP.
  • Understanding of digital design automation infrastructure, including CI, regression testing and HIL testing.
  • Competency with Linux.
  • Knowledge of vendor-provided FPGA development tools with a focus on Xilinx tools.
