This Full time on site position offers great opportunities for career growth.ID: GLS-1About the RoleWe are looking for a Design Verification Engineer to support gate-level simulation (GLS) and hardware emulation activities for our AI chip design and verification teams. In this role, you will help ensure silicon correctness by validating post-synthesis netlists, debugging timing and reset issues, and enabling large-scale emulation of SoC designs prior to tapeout. This is a hands‑on role requiring close collaboration with RTL design, DFT, physical design, and firmware teams.Key ResponsibilitiesSet up, run, and debug gate-level simulations (GLS) for functional, timing (SDF back-annotated), and low-power verification across multiple design blocks and full-chip levels.Support hardware emulation platforms Siemens Veloce including design compilation, bring-up, debug, and regression management.Debug mismatches between RTL and gate-level simulation results, including X-propagation, timing violations, glitches, and clock/reset domain issues.Develop and maintain testbenches, scripts, and flows to automate GLS and emulation compile/run cycles.Collaborate with DFT engineers to validate scan, ATPG patterns, and BIST in gate-level and emulation environments.Work with physical design and STA teams to resolve SDF annotation, timing exceptions, and back-annotated simulation discrepancies.Bring up emulation models for pre-silicon software/firmware validation and performance profiling.Triage and root-cause simulation/emulation failures, track bugs, and drive issues to closure with cross-functional teams.Optimize simulation and emulation runtimes, capacity, and compile turnaround for large SoC designsMaintain documentation of GLS/emulation methodologies, flows,



and known issues.Why Seynamics?Work at one of Europe’s most promising deep-tech semiconductor start up - from silicon to systems - Se* ynamics.Accelerated development path.4 days per week in the Barcelona office (city center), 1 day WFH.1 week of work from everywhere in the world.Competitive package.A collaborative, technical, and growth-oriented environment that values direct ownership and clear thinking.RequirementsRequirements Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or related field. 3+ years of experience in ASIC/SoC design verification, with direct exposure to gate-level simulation. Hands‑on experience with at least one hardware emulation platform (Palladium, ZeBu, Veloce) or FPGA‑based prototyping. Strong understanding of digital design fundamentals: clocking, reset strategies, low‑power design (UPF/CPF), and STA concepts Proficiency with Verilog/SystemVerilog and simulation tools (e.G., VCS, Xcelium, Questa). Experience with SDF back-annotation and timing-accurate gate-level simulation Scripting skills in Perl, Python, or TCL for flow automation and debug. Familiarity with version control (Git/Perforce) and job scheduling systems (LSF/Grid). Strong debugging skills and ability to work independently on complex, ambiguous problems.Preferred QualificationsExperience with DFT flows (scan insertion, ATPG, MBIST) and their validation in GLS/emulation.Exposure to UVM-based verification methodologies.Experience bringing up firmware or software on emulation platforms.Familiarity with low-power verification (UPF-based simulation, power-aware GLS).Experience working on large multi-million gate SoC designs.Knowledge of physical design flows and their interaction with timing closureSENIOR#J-18808-Ljbffr
