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

Job description

We're working with a very well-funded, deeply technical semiconductor company building next-generation silicon for high-performance AI compute - a new architecture rather than an iteration on existing designs. Backed by top-tier investors and moving fast toward first customer silicon, this is ground-floor work on hardware that doesn't exist anywhere else yet.

They're looking for a Senior Mixed-Signal Verification Engineer to own verification of the analog and mixed-signal subsystems at the heart of their high-speed IO - the boundary where analog behavior meets digital control. This is one of the hardest and highest-leverage problems in the design flow.

The Role

You'll own verification of high-speed IO RX/TX chains - CDRs, phase interpolators and clock generation, equalization, samplers and slicers, deserializers - and the digital control loops wrapped around them. The goal: find bugs in silicon-accurate simulation, not in the lab.

What Sets This Role Apart

• Ground-floor impact on a genuinely new chip architecture, not legacy silicon
• Real ownership - your sign-off decisions determine what ships to tape-out
• High technical bar, small elite team, very well capitalized with a clear path to first customer silicon

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

Requirements

• 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

• Strong working knowledge of high-speed SerDes/wireline architectures
• UVM or other constrained-random, metric-driven verification experience
• Scripting for regression and flow automation (Python, TCL, Make)
• Track record of mixed-signal IP sign-off through tape-out, plus silicon bring-up

Package & Process

Compensation is highly competitive with meaningful equity - genuine ownership in the outcome, not just a salary. Additional benefits include a location-based proximity bonus and employer-contributed retirement plans.

The interview process is rigorous and technical, consistent with the caliber of engineering team you'd be joining.
