###### **Description**
We are seeking a Senior or Principal Verification Engineer to assume ownership of our core (top\-level) testbench, along with the verification methodology, tooling, and continuous integration infrastructure that support it. In this role, you will be responsible for evolving the top\-level UVM environment, integrating unit\-level verification IP, driving functional and code coverage closure across the core, and identifying verification gaps at the boundaries between units. You will also serve as a technical er within the organization, contributing to the company\-wide initiative to advance AI\-powered verification methodology. This position requires a rigorous, detail\-oriented approach to verification and the ability to provide technical guidance and mentorship to engineers across the design verification organization.
**Key Responsibilities*** Core testbench ownership — Own, improve, and continuously evolve the top\-level core testbench and its UVM environment. Extend the testsuites, and integrate all the unit\-level VIPs so block\-level checkers, monitors, and coverage are reused at top level.
* Coverage — Own functional and code coverage at the core level: review the nightly results, drive closure across units, and audit covergroups and tests for real quality and intent.
* Cross\-unit gap hunting — Find and close verification holes at the boundaries between units. Reconcile assume/guarantee relationships across unit testbenches: e.g., everything one module assumes about surrounding modules, needs to be verified by surrounding modules' testbenches.
* Methodology, tooling \& CI — Own the verification flows (compile, coverage collection, regression) and the CI as the core RTL evolves: update compile configs, retire stale jobs, create new ones, keep regressions healthy and efficient. Drive concrete upgrades — migrate our scripts and flows to latest versions (e.g., start using Questa One and next\-generation coverage, from Siemens, instead of the old flow) — and stay in regular contact with EDA vendors to keep us on the latest capabilities.
Technical ership \& mentorship — Act as the* technical reference for core verification engineers, review block\- and core\-level testbench architectures, and mentor on coverage\-driven and assertion\-based verification.
**Why Seynamics?*** Work at one of Europe's most promising deep\-tech semiconductor scale\-ups.
* Accelerated development path.
* 4 days per week in the Barcelona office (city center), 1 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.
###### **Requirements**
**Must Have*** 10\+ years of hands\-on design verification, including significant experience verifying processor cores (RISC\-V ideally) or complex microarchitecture.
* Expert SystemVerilog and UVM; building reusable, configurable, multi\-agent environments and integration testbenches.
* Strong functional\-coverage and verification\-planning skills.
* Deep hands\-on Questa (our primary simulator) and a debug tool such as Visualizer / Verdi; other simulators (VCS, Xcelium) a plus.
* Strong Python scripting (plus Bash / Tcl) and practical ownership of verification CI/CD and regression infrastructure.
* Assertion\-based verification (SVA) and the ability to reason about cross\-block assume/guarantee contracts.
* B.Sc. or M.Sc. in Electrical Engineering, Computer Engineering, or a related field.
**Nice to Have*** RISC\-V Core Verification.
* Formal Verification.
* Emulation platforms (Veloce, ZeBu).
* Core/Bus interface protocols (e.g., AXI/CHI).
**Essential Soft Skills*** An adversarial, gap\-seeking mindset — instinctively asks "who actually checks this?" — with a strong umbrella view of the whole core.
* Clear communication across DV, design, and software teams; writes verification plans others can follow.
