Job Description:

We’re looking for a Functional Safety & RAS Lead to help us build safe and highly reliable compute platforms for automotive, robotics, physical AI, data center, and other demanding applications.

This is an individual contributor role for someone who knows functional safety deeply and also likes working with customers and getting complex work done. You’ll work across the product lifecycle, partnering with customers, technical architects, and engineering teams to turn safety and reliability needs into products we can deliver.

What you'll do

• Work with customers and internal teams to understand functional safety and RAS needs, from initial requirements and safety goals through development, assessment, release, and customer support. Partner with the technical architect to define the capabilities to meet customer requirements.

• Be a go-to expert on functional safety, especially ISO 26262 and IEC61508 and how they apply to processor and SoC products.

• Define program scope, milestones, dependencies, risks, and engineering resource needs based on customer and product requirements.

• Keep work moving across architecture, design, verification, software, quality, program management, product, and customer-facing teams.

• Make sure safety requirements and decisions stay traceable through implementation, verification, documentation, product changes, and releases.

• Identify gaps and technical risks, including dependent failures and common-cause concerns, and work with architect and engineering teams to address them.

• Support customer assessments, internal reviews, external assessors, audits, and certification activities.

• Partner with product, sales, and applications teams on customer questions, safety documentation, and product integration guidance.

What we're looking for

• You have a record of getting cross-functional work done across teams you don’t manage.

• Deep knowledge of functional safety and ISO 26262, including FMEDA, fault modeling, diagnostic coverage, safety cases, and fault-injection planning.

• Experience applying functional safety standards to semiconductor, processor, or SoC development and working directly with automotive customers.

• Enough knowledge of processor or SoC architecture and development to work effectively with architecture, design, and verification teams.

• Experience with RAS concepts and mechanisms, including fault detection, error reporting, containment, and recovery.

• Experience running complex, cross-functional technical programs, including scope, dependencies, risks, and resource needs.

• Familiarity with IEC 61508 or other relevant functional safety standards is a plus.

• Active in the standards community, able to influence and get credibility.

Required Qualifications

• Bachelor’s or Master’s degree in EE, CE, CS, or a related technical discipline, or equivalent experience.

• 10+ years of experience in functional safety, RAS, hardware reliability, or related work in semiconductor, processor, SoC, or other complex hardware development.

• 5+ years of experience in semiconductor, SoC, processor-IP, or complex hardware development, including significant architecture or technical-leadership responsibility.

• Deep experience applying ISO 26262 and functional safety methods such as FMEDA, FMEA, fault-tree analysis, diagnostic coverage, and fault injection.

• Strong understanding of SoC and IP development, from requirements and architecture through verification, release, and customer support.

• Experience with features intended to detect and address hardware random failures, such as error detection and reporting, fault containment, redundancy, lockstep, ECC/parity, memory protection, or recovery.

• Experience leading complex, cross-functional technical programs across engineering teams.

• Strong communication and judgment, with the ability to work across technical teams, customers, and other stakeholders.

Preferred Qualifications

• Experience with RISC-V processor or SoC architecture and automotive semiconductor IP developed to ASIL-B or ASIL-D objectives.

• Experience with RAS for data center, AI, robotics, or other high-availability compute products.

• Experience with reliability analysis or testing, including soft-error-rate modeling or radiation testing.

• Experience working with certification bodies or external assessors.

• Familiarity with related standards such as ISO/SAE 21434 or cybersecurity engineering is a plus.
