CPU Verification Engineer (Senior/Principal)

NUVACORE, Inc.; Austin, Northern (TX, KY); Hybrid; USD 120,000 - 220,000; Full time

Job summary

NUVACORE, Inc. is seeking Verification Engineers at multiple levels—from Senior to Principal—to help prove the correctness of the Nuvacore CPU. You will join the design verification team to build test plans, environments, and checkers, collaborating with architecture and RTL design.

Responsibilities include driving verification strategy, building scalable environments, generating tests in assembly, C, or RIS, and closing coverage. You'll work with emulation, FPGA, and silicon bring-up.

Qualifications

• Degree in Electrical/Computer Engineering, Computer Science, or equivalent practical experience.
• 15+ years (Principal) or 4+ years (Senior) of design-verification experience, ideally on a CPU or complex digital design.
• Strong knowledge of CPU micro-architecture and digital logic — pipelines, out-of-order execution, and branch prediction.
• Hands-on functional verification: test plans, testbenches, checkers, transactors, and coverage.
• Proficiency in C/C++ and/or SystemVerilog, plus a scripting language (Python; Perl a plus).
• Experience writing and debugging tests in assembly for CPU verification.

Responsibilities

• Plan & Strategy: Drive the verification scope, strategy, and test plans for the CPU at unit and/or top level of the CPU design.
• Environment Setup: Build, maintain, and scale robust verification environments — stimulus generators, checkers, transactors, and coverage.
• Test & Debug: Generate complex directed and random tests in assembly, C, or random instruction sequences to expose corner cases.
• Performance Verification: Partner with architects to correlate RTL against performance models, hunting throughput and branch-prediction issues.
• Coverage Closure: Define the coverage space, write functional coverage monitors, and analyze metrics to prove test plan completeness.
• Cross-functional Collaboration: Work with architecture and RTL teams to root-cause failures and support emulation, FPGA, silicon bring-up.
