Principal / Lead Wireless Communications System Architect

Key Responsibilities

• Define system architecture for next-generation multi-antenna and SDR-based communication platforms, influencing product strategy and long-term roadmap planning.
• Lead technical engagement with strategic customers, representing system trade-offs, negotiating performance specifications, and aligning joint integration plans.
• Architect and maintain MATLAB and analytical models capturing the full signal chain, including channel modeling, quantization noise allocation, SNR budgeting, interplay of RF non-linearities, and DSP algorithm design constraints.
• Generate precise block-level specifications for digital baseband, calibration engines, channel processing, mixed-signal converters, and RF interfacing elements; ensure internal teams understand the architectural rationale behind these specifications.
• Drive alignment between digital architecture, signal processing algorithms, mixed-signal circuit selections, ADC/DAC dynamic range decisions, LO/subsystem noise considerations, and thermal/power constraints.
• Collaborate with validation and silicon bring-up teams to ensure post-silicon results trace back to modeled assumptions; define measurement-level KPIs and debug methodologies when deviations arise.
• Mentorship & Team Development: Provide architectural guidance to system engineers, signal processing developers, and hardware design teams; develop reusable models, internal best practices, and system-level methodologies.
• Thought Leadership: Participate in internal architecture reviews, contribute to core IP innovation strategy, and represent the company in technical engagements, standards-relevant discussions, and key customer milestones.

Qualifications

• Graduate degree in Electrical Engineering, Communications Engineering, or related field; PhD strongly preferred.
• 12+ years of experience in wireless communications system architecture for advanced SDR systems.
• Demonstrated ownership of end-to-end communication signal chains, including cascaded error budgeting, quantization trade-offs, and performance modeling across RF, ADC/DAC, and DSP blocks.
• Deep expertise in: MIMO and multi-user spatial processing architectures, Channel estimation, SNR/phase-noise budgets and their mapping into mixed-signal design requirements.
• System-level modeling using MATLAB or Python.
• Ability to articulate complex system decisions to both internal engineering teams and senior-level customers.
• Proven leadership in defining specifications consumed by RTL design, mixed-signal design, verification, and system validation teams.
• Strong customer communication skills and comfort presenting architectural trade-offs to VP- and CTO-level stakeholders.
