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 .

• 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.
