Principal​/Lead Wireless Communications System Architect

Title: Principal / Lead Wireless Communications System Architect

Location: US, Europe

Job Type: Full-Time / Consultant

Industry: Wireless Communications, Software-Defined Radio (SDR), Semiconductor IP and Advanced SoC

Job Description: We are seeking a Principal / Lead Wireless Communications System Architect to own the definition and architectural direction of complex wireless and multi-antenna system platforms. The role will serve as the primary technical interface with customer system teams, lead system modeling and performance analysis, drive architectural decisions across mixed-signal and digital subsystems, and define system-level specifications that translate into silicon implementations.

• Technical Leadership and Direction: Define system architecture for next-generation multi-antenna and SDR-based communication platforms, influencing product strategy and long-term roadmap planning.
• Customer Technical Ownership: Lead technical engagement with strategic customers, representing system trade-offs, negotiating performance specifications, and aligning joint integration plans.
• End-to-End System Modeling: 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.
• Block-Level Specification Ownership: 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.
• Cross-Domain Integration: 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.
• System Verification Alignment: 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.

• 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.

• Highly competitive compensation, performance incentives, and substantial technical influence.
• Direct ownership of architecture direction for multiple next‑generation communication product lines.
• Opportunity to shape strategic relationships with top‑tier global customers.
• A technical culture that values rigor, clarity, and architectural craftsmanship.
