Openchip

If you are a semiconductor engineer looking for a chance to work on next-generation CPU and SoC design, the small but deeply technical team at Openchip is currently hiring across four positions — all based in Limerick with hybrid working arrangements. Openchip is a European systems company building a portfolio of accelerators, infrastructure hardware, and full-stack software to drive AI and HPC applications, with a stated mission to advance Europe's digital sovereignty through top-tier silicon and software engineering.

The most prominent jobs at Openchip are the Senior CPU Architect and Staff CPU Architect roles. Both focus on the architectural and micro-architectural specification of out-of-order superscalar CPU cores for next-generation System-on-Chip designs, with a strong emphasis on performance and power/area efficiency. The Senior Architect requires 7+ years of experience in OOO CPU design, while the Staff-level role — a leadership position — asks for 10+ years with a track record of successful delivery. Candidates should have deep understanding of CPU micro-architectures, memory hierarchy, coherency in multi-core systems, and experience using advanced functional and performance simulators for architecture exploration. Knowledge of the RISC-V architecture is listed as an additional area of interest.

A Senior Engineer, Functional Verification opening targets engineers with 7+ years of experience verifying complex SoC or IP blocks. The day-to-day involves developing verification environments in SystemVerilog, UVM, SystemC, and C++, executing verification plans, running regressions, and debugging test failures. Proficiency in constrained-random methodology, functional-coverage development, and tools such as simulators, coverage analysers, and continuous-integration pipelines is expected.

Rounding out the current openings is a Platform Applications Engineering Lead — a team-management role responsible for defining and executing the customer-enablement strategy for Openchip's hardware and software products. This person leads a cross-disciplinary team of application engineers spanning AI, hardware, and software domains, and works directly with strategic partners during integration and deployment in real-world data-centre and HPC environments. For chip designers, verification engineers, and platform leaders looking to help build Europe's next AI hardware platform, jobs at Openchip in Limerick represent a rare opportunity in the Irish market.
