Job summary

Platform Recruitment is seeking a Senior Mixed-Signal Verification Engineer to own verification of analog and mixed-signal subsystems at the heart of a new chip architecture. You will lead verification of high-speed IO RX/TX chains and the digital control loops surrounding them, aiming to catch silicon-accurate bugs before tape-out.

The role offers independent ownership, a high technical bar, and meaningful equity within a well-capitalized startup environment moving toward first customer silicon.

Qualifications

• BS/MS in Electrical Engineering or related field, with 5+ years of analog/mixed-signal verification on complex SoCs or mixed-signal IP
• Hands-on expertise with AMS modeling and verification: Verilog-AMS, real-number modeling, and analog-digital co-simulation flows
• Proficiency in SystemVerilog with assertion-based verification and self-checking testbench architecture
• Demonstrated ability to model analog blocks and validate against transistor-level references
• Strong debug skills across the analog/digital boundary
• Nice-to-have: SerDes/wireline architectures, UVM or constrained-random verification, scripting for regression and flow automation, track record of mixed-signal IP sign-off through tape-out, plus silicon bring-up

Responsibilities

• Own verification strategy and test plans for mixed-signal subsystems, block level through top-level integration
• Define modeling approach and fidelity tiers (real-number model vs. Verilog-AMS vs. transistor-level co-sim) and the associated accuracy/runtime trade-offs
• Build self-checking testbenches for analog/digital interactions - loop convergence, mode transitions, clock-domain crossings
• Drive AMS co-simulation flows and define functional coverage targeting analog corner behavior
• Debug and root-cause failures across the analog/digital boundary through to closure
• Own block- and subsystem-level sign-off for tape-out, including coverage closure
