Hybrid
Senior Level, Lead/Staff
$170K/yr - $285K/yr
5+ years expOLIX is seeking highly skilled and motivated Senior / Staff Digital Verification Engineers with a strong background in CMOS digital design and verification. The role involves taking ownership of the functional correctness of high-speed, real-time data-processing silicon and collaborating with various teams to ensure proper integration and validation of advanced digital pipelines.
Semiconductors
Responsibilities
Own end-to-end verification of high-throughput digital pipelines supporting multi-GSPS input rates, continuous streaming data paths, deep pipelining, and robust hand-shaking in advanced CMOS nodes
Develop and maintain comprehensive verification environments using SystemVerilog/UVM, including constrained-random testing, coverage closure, and regression automation
Define and implement assertion-based verification strategies for control logic, data-path correctness, CDC/RDC, and protocol compliance
Apply formal verification techniques (property checking, assertions, equivalence checking) to complement simulation-based verification and accelerate bug discovery
Model and validate algorithms using MATLAB/Simulink or Python, ensuring functional equivalence from algorithmic models through RTL and gate-level sign-off
Support FPGA prototyping and silicon bring-up by developing targeted testcases, debug strategies, and post-silicon validation plans
Collaborate closely with digital design, optical-hardware, mixed-signal, and software teams to ensure correct integration across clock domains, interfaces, and firmware abstractions
Analyse verification results to identify root causes, drive design fixes, and improve verification efficiency and reuse
Contribute to verification methodology development, documentation, and design/verification reviews; mentor junior engineers where appropriate
Qualification
Required
5+ years of hands-on experience in digital verification for high-performance ASICs or SoCs
Ownership of verification for at least one complex block or subsystem processing continuous real-time data streams
Strong proficiency in SystemVerilog, assertions (SVA), and modern verification methodologies (e.g. UVM. CocoTB)
Proven experience verifying designs operating in GHz-class clock domains, including CDC/RDC analysis
Familiarity with industry-standard EDA flows: RTL simulation, formal verification, linting, CDC/RDC, STA, power-intent (UPF/CPF), and gate-level simulation
Experience verifying high-speed IP such as SerDes, DDR/HBM, PCIe, Ethernet, or similar interfaces
Proficiency with MATLAB/Simulink or Python/NumPy for algorithm modelling, fixed-point analysis, and test-vector generation
Solid grounding in digital design principles, computer architecture, DSP fundamentals, and semiconductor basics
Clear communicator who collaborates effectively across disciplines and is comfortable operating in a fast-moving, evolving environment
Preferred
Tape-out experience at 22 nm or below
Deep hands-on experience with formal verification methodologies, including property decomposition, and coverage-driven formal on tools such as Jasper
Exposure to coherent optical links or photonic-electronic co-design
Familiarity with AI/ML workloads, systolic arrays, or tensor-processing architectures
Expertise in arithmetic pipeline verification
Expertise in processor and ISA verification
Contributions to open-source RTL, verification frameworks, or FPGA platforms
