onsemi

With 11 positions based in Cork, jobs at onsemi centre on the semiconductor company's analog and mixed-signal design operations, which form a key part of its global R&D footprint. The Cork office is an established design centre that contributes to onsemi's portfolio of power management, sensor, and connectivity solutions used in automotive, industrial, and IoT applications.

The engineering roles are predominantly in analog IC design — a specialised discipline requiring deep expertise in CMOS, BiCMOS, or BCD process technologies. Openings for Analog Design Engineers, Senior Analog Design Engineers, and Principal Design Engineers involve full-cycle IC development: architecture definition, schematic design, simulation (Cadence Virtuoso, Spectre), layout review, and silicon validation. If you're wondering what products these roles support, jobs at onsemi in Cork typically relate to power management ICs (PMICs), DC-DC converters, LDO regulators, and motor drivers — components critical to electric vehicles, industrial automation, and energy-efficient electronics.

Verification and test engineering complement the design positions. Verification Engineers develop and run simulation testbenches using SystemVerilog, UVM, and mixed-signal simulation environments, while Test Engineers create production test programmes for fabricated silicon. The Product Engineer role bridges design and manufacturing, working with foundry partners and test houses to ensure yields and quality meet specifications.

Applications engineering is another area of focus. Applications Engineers work closely with customers — often automotive OEMs and Tier 1 suppliers — to integrate onsemi's silicon into their systems. These roles require a blend of circuit design knowledge and customer-facing communication skills, supported by experience with evaluation boards, reference designs, and EMC/thermal analysis.

For semiconductor professionals in the Munster region, jobs at onsemi provide access to cutting-edge IC design work without having to leave Cork. The company's global scale means engineers work on products that ship in volumes of hundreds of millions, while the Cork centre's focused mandate ensures technical depth rather than breadth.

The combination of analog design heritage, automotive market growth, and Cork's established semiconductor talent pool makes onsemi a compelling option for IC design and verification engineers looking for long-term career development.
