Be part of a global R&D organization with strong local ownership and decision-making.
Collaborate with hardware, RF, software, mechanical, and chipset partners.
See your designs go from concept to mass production.
Thrive in a fast-paced, innovative, and multicultural environment.

Reporting to the HW Manager

You act as RF technical authority for wireless products developed in our US R&D center. You drive RF architecture choices, ensure high-level RF performance, and secure regulatory compliance across the full product lifecycle, from early concept to mass production and field deployment.

Responsibilities

• RF Architecture & Leadership
• Act as RF expert and reference for the R&D organization.
• Define and validate end-to-end RF system architectures (Wi-Fi, Cellular, ISM, DECT) for gateways and extenders.
• Drive trade-offs (performance, cost, complexity, regulatory margin) and support product roadmap decisions.
• Review and challenge RF designs from internal teams and external partners (ODM, chipset vendors, antenna suppliers).
• Product Definition & Development
• Define RF specifications aligned with customer needs, standards, and FCC regulations in collaboration with HW, mechanical, and system teams.
• Lead RF development including feasibility studies, RF/antenna architecture definition, schematic reviews, antenna optimization, and PCB layout guidance.
• Ensure robust RF integration within constrained mechanical environments.
• Define and apply EMC design rules (layout, grounding, shielding, filtering) at system and product levels.
• RF Validation, Calibration & Performance
• Define advanced RF validation strategies: conducted/radiated tests, coexistence, immunity, TRP/TIS, EVM, sensitivity, throughput.
• Develop calibration strategies: lab characterization, manufacturing flows, field tuning mechanisms.
• Perform EMC pre-compliance to anticipate FCC certification.
• Regulatory & Certification
• Lead radio certification strategy and execution (FCC, BT, Thread, regional approvals).
• Interface with test labs, certification bodies, and consultants.
• Anticipate regulatory changes and ensure early compliance.
• Cross-functional Collaboration
• Work closely with software, manufacturing, test, supply chain, and quality teams.
• Define and review RF manufacturing test specifications.
• Support production ramp-up and yield improvement.
• Field Support & Root Cause Analysis
• Lead RF performance investigations from field issues.
• Perform root cause analysis.

• Spectrum analyzers
• Vector Network Analyzers (VNA) for S-parameter measurements, impedance matching, antenna characterization, and RF component validation.
• Signal generators
• Vector signal analyzers for modulated signal qualification (EVM, IQ, phase noise, coexistence).
• Extensive experience in antenna characterization in anechoic chambers (microwave bands).
• Advanced use of 2D/3D electromagnetic simulation tools (CST, HFSS or equivalent) for antenna and RF design.
• RF simulation tools (ADS, AWR, or equivalent)
• Wireless standards and technologies, including:
• Wi-Fi 6 / Wi-Fi 6E (802.11ax)
