Leads global legal support for Nokia’s intellectual property monetization, including patent transactions, licensing, M&A, and strategic initiatives. Provides specialist legal advice to partnering, licensing, strategy, patenting, and commercial teams; develops governance and compliance processes; mitigates risks; improves operational efficiency; and trains internal stakeholders. The role requires cross-functional coordination, practical IP law expertise, and support for strategic execution.

Own end-to-end DFT architecture, implementation, verification, DRC closure, test coverage, timing constraints, and post-silicon debug for ASICs. Work across Logic BIST, MBIST, BISR, scan compression, Boundary Scan, JTAG, ATPG, and mixed-signal IP integration. Collaborate with architecture, RTL, physical design, and product teams to resolve design and testability issues, automate flows using TCL, support hierarchical integration, and achieve first-pass silicon success.

Administer and modernize enterprise Microsoft SQL Server platforms supporting downtime-sensitive semiconductor and telecommunications manufacturing. Responsibilities include advanced T-SQL and SSIS development, performance tuning, backup and disaster recovery, high availability, security, automation, migrations, cloud adoption, capacity planning, incident response, and database architecture. The role provides technical leadership, mentoring, documentation, and cross-functional guidance in 24/7 production environments.

Develop, optimize, and integrate 5G NR L2/L3 protocol stacks (MAC, RLC, PDCP, RRC, NGAP). Implement scheduling, HARQ, buffer management, and mobility features. Debug protocols using tracing tools and integrate L2/L3 with PHY and 5GC to improve throughput, latency, and handover performance.

Design, implement, and optimize 5G NR gNB PHY layer algorithms and real-time signal processing on DSP/FPGA/GPU. Integrate PHY with RF front-end, maintain 3GPP compliance, perform unit/integration testing, debug and tune performance, and mentor junior engineers.

Design and implement high-performance, 3GPP-compliant 5G Core control- and user-plane functions on ARM-based embedded Linux. Develop in C/Go/Rust, use DPDK for packet processing, optimize latency/throughput, debug protocol and performance issues, and collaborate cross-functionally to integrate carrier-grade systems.

Designs and characterizes photonic integrated circuits and high-speed optical components, including lasers, detectors, modulators, and integrated waveguides. Performs RF and electro-optical modeling using HFSS and ADS, develops experiments, analyzes device performance data, and collaborates with fabrication, testing, reliability, packaging, systems, and product engineering teams. Requires advanced expertise in optical communications, DWDM systems, component fabrication, epitaxy, testing, and signal analysis.

Provides technical leadership for the design, development, integration, qualification, and testing of tunable lasers, high-speed semiconductor optical devices, and photonic integrated circuits. Leads designers and cross-functional collaboration with fabrication, epitaxy, testing, reliability, packaging, product, and systems engineering teams. Defines product requirements, improves design methodologies, resolves technical challenges, supports product roadmaps, and applies statistical analysis to development data.

Develops wafer-level photonic integrated circuit burn-in and test solutions for R&D and high-throughput production. Responsibilities include designing validation test plans and algorithms, developing hardware and software with vendors, qualifying test stations, applying Gage R&R and SPC, troubleshooting complex systems, automating instrumentation and data acquisition, analyzing results, and documenting solutions for cross-functional teams.
