About onsemi 

onsemi is driving innovation in power, sensing, and automotive semiconductor solutions to enable a more sustainable future. Our Treo™ platform underpins next-generation intelligent power systems for automotive and industrial markets, emphasizing safety, reliability, and scalability. 

Role Overview 

We are seeking a senior Digital Design Member of Technical Staff (MTS) to lead and deliver digital controller IP for power, clock, and error management subsystems within the onsemi Treo™ platform. This role is a hands-on technical leadership position, focused on architecting, designing, integrating, and evolving complex digital IP that tightly interfaces with analog and mixed-signal blocks in automotive-grade SoCs. 

The successful candidate will bring deep experience in automotive functional safety, digital-analog co-design, and system-level integration, while also serving as a technical mentor and thought leader within the Cork design organization. 

Key Responsibilities 

• Architect, design, and implement digital system controllers for:

Power management 

Clock management 

Error detection, reporting, and mitigation subsystems 

• Develop robust digital IP that controls and interacts closely with analog and mixed-signal blocks. 

• Own IP delivery from architecture through RTL, verification, integration, and silicon bring-up support. 

• Drive and support digital-on-top product integration flows, including:

IP integration into SoC environments 

Clocking, reset, power domain, and safety integration 

• Ensure designs meet automotive functional safety requirements (e.g., ISO 26262 concepts such as ASIL, fault coverage, diagnostic mechanisms). 

• Collaborate cross-functionally with:

Analog design 

Verification 

Physical design 

Systems, safety, and product engineering teams 

• Define and evolve IP roadmaps aligned with:

Platform strategy 

Product requirements 

Long-term business objectives 

• Mentor and technically guide junior and mid-level engineers, promoting best practices in design, documentation, and review culture. 

• Contribute to continuous improvement of:

Design methodologies 

Verification strategies 

Automation and productivity tools 

• Stay technically curious and engaged with emerging AI/ML applications in digital design, including their potential impact on RTL development, verification, and productivity. 

   

Required Qualifications 

• 15+ years of hands-on digital design experience, primarily in ASIC or SoC development. 

• Proven experience delivering automotive IP with functional safety requirements. 

• Strong background designing digital controllers for analog blocks (e.g., power regulators, PLLs, sensors, clocking systems). 

• Deep understanding of system-level digital integration, including:

• Power and clock domain management 

• Reset strategies 

• Error handling and safety mechanisms 

• Solid experience with RTL design (SystemVerilog). 

• Working knowledge of constrained-random verification methodologies, including SystemVerilog and UVM. 

• Demonstrated ability to work effectively as a senior individual contributor, owning complex technical problems end to end. 

• Strong communication skills and a demonstrated willingness to mentor junior engineers. 

   

Preferred / Plus Qualifications 

• Experience with automotive safety standards such as ISO 26262 (concept, system, or IP-level application). 

• Working knowledge of JIRA for task tracking and JAMA for requirements management. 

• Exposure to safety diagnostics, fault injection, or safety verification techniques. 

• Experience contributing to platform-level IP strategies or multi-generation roadmap planning. 

• Familiarity with low-power design techniques and power-aware verification. 

What We Offer 

• Opportunity to work on industry-leading automotive and power semiconductor platforms. 

• A senior, high-impact technical role with architectural ownership. 

• A collaborative engineering culture with strong ties between digital, analog, and system teams. 

• Competitive compensation and benefits. 

• Career growth within a global semiconductor leader, while being based in Cork’s vibrant technology ecosystem.
