K Two Technology Consulting AB jobb

We look for system focused engineers to work with early-phase studies and simulation work for 5G NR feature evolution. Role Purpose System design, feature development, and verification teams, with a focus on simulation-driven analysis and 3GPP-aligned architecture exploration. The role supports for Layer 1 (PHY) and for Layer 2 (MAC/RLC/PDCP). Key Responsibilities Lead and support technical studies during feature pre-development. Execute simulation-based evaluations (link-level, scheduler behaviour, accelerator feasibility). Provide architectural input and early design feedback to development teams. Align technical work with 3GPP standards and internal Ericsson architecture (e.g., MSRBS, GPP). Collaborate cross-functionally with system, software, and verification teams. General Competence Requirements Solid grasp of the 5G NR protocol stack (based on 3GPP). Familiarity with simulation environments and analytical tools. Capability to work independently, document findings, and communicate effectively. Willingness and ability to ramp up on Ericsson-specific platforms. Layer 2 (L2) Focused Candidate Must-Have Skills: Deep understanding of: MAC scheduling, multiplexing Logical-to-transport channel mapping Buffer Status Reports (BSR), Scheduling Requests (SR) RLC modes: TM, UM, AM Knowledge of: User Plance Control (UPC) Radio Resource Management (RRM) Nice-to-Have: PDCP knowledge (ciphering, header compression) Experience with simulation or log analysis tools Python/Matlab/C++ scripting for automation or modelling Layer 1 (L1) Focused Candidate Must-Have Skills: Strong experience in: Link-level simulations (e.g., Falcon) 5G PHY protocol stack: UL/DL procedures, HARQ, beamforming Waveforms and signal design (OFDM, SC-FDMA) Channel coding (LDPC, Polar) Synchronization signals (PSS/SSS, DMRS, CSI-RS) Slot/frame structure understanding (38.211/213) Nice-to-Have: Experience integrating simulations with HW testbeds Understanding of FAPI/nFAPI or O-RAN PHY interface specs Ramp-Up & Support Prior experience with Ericsson internal platforms is not required. Onboarding and mentorship will be provided to help candidates ramp up effectively on Ericsson tools and workflows.

RF Engineer – Radio Testing & Integration We are looking for a skilled RF Engineer with solid experience in RF testing, integration, and troubleshooting. This role involves working with lab-based radio systems, test equipment, and network validation. Candidates with more than 5 years of experience are welcome, though we strongly prefer profiles with 8–10+ years of deep, hands-on RF experience.
