Job Description:

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 About the Company: Omni Design Technologies is a leading provider of high-performance, ultra-low power IP solutions across advanced CMOS nodes, enabling differentiated SoC architectures for 5G, optical networks, LiDAR, radar, automotive networking, AI acceleration, imaging, and related high-growth markets. We partner with market leaders globally and are scaling rapidly. We are seeking senior technical leadership talent to define and guide the next generation of adaptive, multi-antenna wireless platforms. 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. This individual 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. This is a senior leadership role with substantial influence across product definition, roadmap direction, and customer engagement. The ideal candidate has a deep understanding of communications theory, system decomposition across analog/digital boundaries, quantization/error propagation, MIMO signal processing architectures, and end-to-end error budgeting strategies in SDR-based environments. Key Responsibilities: 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. Qualifications: Graduate degree in Electrical Engineering, Communications Engineering, or related field; PhD strongly preferred. 12years 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. What We Offer: 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. We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
