Drive engineering optimization, yield improvements, automation, and product performance for Nokia’s 800G coherent optical pluggable modules. Analyze large datasets, improve manufacturing capability, maintain product engineering infrastructure, ensure specification traceability, and support prototype development and volume production in collaboration with hardware, test, firmware, reliability, and manufacturing teams.

Design, simulate, prototype, and test RF circuits for wireless infrastructure products. Develop signal-processing algorithms, digital predistortion, and passive intermodulation cancellation techniques. Support TRX design activities, technical documentation, design reviews, subcontractor collaboration, and engineering problem-solving while staying current with RF and microwave technologies.

Designs and develops RF/microwave circuits and high-power amplifiers for 5G/6G base stations throughout the product lifecycle. Responsibilities include amplifier architecture, matching networks, simulation, laboratory testing, troubleshooting, performance optimization, cross-functional integration, technology innovation, mentoring, and sustainable design. Requires expertise in GaN and Doherty amplifiers, RF simulation tools, CAD layouts, and product development.

Designs and develops RF/microwave circuits and high-power amplifiers from concept through production. Responsibilities include defining RF components, implementing amplifier architectures and matching networks, conducting simulations using ADS, ANSYS, Microwave Office, and HFSS, and testing and troubleshooting components. The role collaborates with procurement, software, mechanical engineering, and manufacturing teams to integrate power amplifiers into RF radios. Travel of up to 10% may be required.

Design, simulate, and test RF circuits for cellular base stations, including transmitters, receivers, ADCs, and power supplies. Document designs, participate in reviews, support subcontractors, collaborate with engineering teams, and use RF electromagnetic and analytical simulation tools. The role requires effective planning, communication, technical problem-solving, and occasional international travel.

Leads the strategic vision, requirements, roadmap, development, and launches of AI infrastructure products. Partners with engineering, customers, and industry stakeholders to address scale-out, scale-up, and scale-across needs, leveraging expertise in merchant silicon and NVIDIA and non-NVIDIA ecosystems. Conducts market and competitive analysis, drives innovation, represents the company externally, and influences cross-functional teams and partners.

Leads Nokia’s Analog/RF/Mixed-Signal ASIC development organization, overseeing product definition, architecture, circuit design, foundry engagement, layout, tape-out, silicon bring-up, testing, qualification, and productization. Builds and mentors technical teams, establishes design methodologies, selects circuit topologies, develops product roadmaps, and collaborates with verification, CAD, product, packaging, and test engineering partners to deliver high-performance SiGe ASIC solutions.

Supports the sales process as the primary technical advisor for Infinera’s telecommunications products. Develops and delivers technical presentations, demonstrations, quotations, and RFI/RFP responses; interprets customer requirements; designs and cost-models solutions; supports marketing events and after-sales activities; and builds long-term customer relationships. The role requires expertise in optical, DWDM, long-haul, metro, access, mobile backhaul, and fronthaul systems, along with strong communication and presentation skills.

Develop algorithms and test methodologies for photonic integrated circuits, run engineering and prototype tests, analyze test data using JMP and Excel, create high-volume production test processes, and troubleshoot hardware and software integration. The role requires programming, test automation, statistical analysis, test instrument experience, and familiarity with optoelectronic devices. This is a full-time, four-month onsite cooperative role in Sunnyvale, California.

Leads the design and development of high-speed analog, RF, and mixed-signal ICs for coherent optical and PAM4 communication systems. Responsibilities include transistor-level architecture, circuit design, layout, silicon bring-up, characterization, RF wafer probing, specification development, design reviews, and collaboration with product engineering and optical systems teams. Provides technical guidance and mentorship while developing solutions using SiGe BiCMOS and CMOS processes.
