Senior RF Engineer – Wireless Systems & Validation

SAGEMCOM; Dallas (TX); On-site; USD 150,000 - 200,000; Full time

Job summary

SAGEMCOM is seeking an experienced RF engineering leader to drive end-to-end RF architecture for residential gateways and Wi‑Fi products. You will collaborate with hardware, RF, software, and mechanical teams to deliver robust RF performance from concept to production.

You will lead calibration, EMC, and certification activities, review external designs, and guide antenna optimization and RF testing across the product lifecycle in a fast-paced, global R&D environment.

Qualifications

• Master’s or PhD in Electronics, Telecommunications, or RF/Microwave Engineering.
• 10+ years of RF/Microwave experience.

Responsibilities

• 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 RF designs from internal teams and external partners (ODM, chipset vendors, antenna suppliers).
• 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.
• 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.
• Identify and mitigate EMI sources (power switching, high‑speed interfaces, RF/digital coupling, antenna interactions).
• Work with PCB, mechanical, and power teams to implement cost‑effective solutions.
• 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 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.
