Arago

Mixed-signal Verification Engineer

Paris Offices. Posted 2 months ago

The role

You will own the methodology, planning, and execution of mixed-signal verification for digital-to-analog interfaces on Arago's Systems-on-Chip. You will work across analog, RTL, architecture, and firmware teams to ensure correct integration and drive verification to sign-off.

What you will do

  • Own the mixed-signal verification methodology and verification plan for digital-to-analog interfaces on Arago SoCs.
  • Build and maintain verification environments at block, subsystem, and SoC level.
  • Develop tests, assertions, checkers, scoreboards, and functional coverage.
  • Verify digital control and configuration of analog/mixed-signal circuitry across normal operation, corner cases, and error conditions.
  • Run regressions, analyze coverage, debug failures, and drive verification to sign-off.
  • Develop or integrate behavioral and real-number models needed for efficient mixed-signal simulation.
  • Work closely with analog, RTL, architecture, firmware, and SoC verification teams to identify and resolve interface issues.

Required qualifications

  • Strong hands-on experience in ASIC or SoC verification.
  • Experience verifying mixed-signal blocks or digital-to-analog and analog-to-digital interfaces.
  • Experience with AMS (analog-mixed-signal) co-simulation flow, and setting up mixed-signal testbenches.
  • Strong SystemVerilog skills and practical experience with UVM or an equivalent verification methodology.
  • Experience building verification environments and developing tests, assertions, scoreboards, and functional coverage.
  • Good understanding of both digital design fundamentals and basic analog/mixed-signal concepts.
  • Strong debugging skills, including the ability to investigate issues spanning RTL, models, clocks, resets, configuration, and analog behavior.
  • Experience with scripting and automation, preferably Python, Tcl, shell, or similar.
  • English at a proficient level.

Nice to have

  • Verification experience with complex high-speed interface IP such as PCIe, DDR/LPDDR, UCIe, SerDes, USB, CXL, or similar PHY-based interfaces.
  • Experience verifying interface initialization, link training, calibration, adaptation, clocking, power-state transitions, or other digital/analog control loops.
  • Experience with real-number modeling, SystemVerilog RNM, wreal, Verilog-AMS, or equivalent mixed-signal verification techniques.
  • Experience developing or integrating behavioral models of analog/PHY components into digital verification environments.
  • Experience with SoC-level integration and verification of complex interface IP.
  • Experience with low-power verification, power-state management, or UPF.
  • Experience driving a complex IP or SoC verification effort through coverage closure and tape-out.

Benefits

  • Competitive cash compensation
  • Meaningful stock option plan
  • Healthcare coverage (including family-friendly options)
  • Pension contributions
  • Professional development support
  • 25 days of PTO
  • Public holidays
