• Cross-Platform Strategy: Drive scalable, reusable software and security frameworks across multiple product generations.
• Technical Governance: Act as design authority in architecture reviews; establish standards, best practices, and technical guidelines.
• Cross-Functional Influence: Partner with hardware, firmware, systems, and product teams to ensure cohesive system integration.
• Customer Engagement: Interface with strategic customers on software architecture and security requirements; support audits and technical reviews.
• Supplier Oversight: Evaluate and influence third-party components and vendors for software compatibility and security compliance.
• Problem Solving: Lead resolution of complex system-level issues and guide root cause analysis for critical failures.

What We’re Looking For

Education:
Bachelor’s or Master’s degree in Computer Engineering, Computer Science, Electrical Engineering, or related field.

Experience:
The ideal candidate will have:

• 8+ years of experience in embedded systems, system software, or platform architecture
• Proven experience defining system-level architectures across multiple products
• Deep expertise in Linux-based embedded systems and hardware/software integration
• Strong background in security (secure boot, encryption, authentication, key management)
• Demonstrated ability to influence cross-functional teams and drive architectural decisions

Skills:

• Experience in optical transport, telecom, or data center systems
• Knowledge of industry security standards (e.g., NIST, IEC 62443, ISO 27001)
• Experience with Tier 1 or hyperscale customer engagements.

Perks You’ll Love

• Flexible time off
• Health and wellness benefits (physical and mental)
• Tuition reimbursement and career growth support
• A workplace built for you: free gym, games room, prayer room
• Subsidized meals, free coffee/tea
• Employee stock options and incentive plans
