- IEEE 802.11 standardization: Attend and actively participate in IEEE 802.11 standardization meetings and other industry fora, to promote technical contributions, and contribute to future Wi-Fi specifications.
- Use simulations and prototypes: Design and implement system-level and link-level simulations, analytical evaluations, testbed experiments, and proof-of-concept demonstrations to validate new concepts and assess their practical feasibility.
- Evaluate real-world performance: Study Wi-Fi behavior in realistic environments, including interference, mobility, hidden-node conditions, dense deployments, heterogeneous networks, and coexistence with other radio technologies.
- Collaborate across the organization: Work closely with researchers and experts in radio, networking, AI, devices, cloud platforms, and product development to translate research results into compelling technical and business opportunities.
- Build external partnerships: Establish productive collaborations with universities, industry partners, standards organizations, and other stakeholders in the global Wi-Fi ecosystem.
The skills you bring:
- A PhD or experienced MSc., or equivalent, in wireless communications, signal processing, automatic control, mathematical statistics, or a related field. Preferably, but not necessarily, with a specialization towards radio and physical layer aspects of wireless communication.
- Analytically and creatively thinking with a strong personal drive, perseverance, and focus on delivering high-quality results.
- Able to formulate research problems, develop innovative solutions, analyze performance, and communicate results clearly.
- Experienced from one or both of physical layer and medium access control layer design.
- Skilled in programming, in particular with building or using link and system level simulators, for example in Matlab, Python, C++ or Java.
- Excellent in written and verbal communication, with the ability to work effectively in international, cross-functional, and collaborative environments.
- Proficient in using AI, e.g., Claude and KIRO, for both programming and general tasks.
- Merited with a record of publications, patents, technical contributions, or participation in standardization activities related to wireless communications or networking is a plus.
- Willing to travel internationally.
