Junior Functional System Developer

At Ericsson, we invite you to join us Functional System Developer role. The developer is responsible for designing and systemizing how Ericsson radio products behave by converting market and technical requirements into precise functional specifications. The role ensures correct end‑to‑end radio functionality across key domains such as TX/RX carrier handling, antenna calibration, synchronization and timing, radio security, energy efficiency, and thermal protection. It includes maintaining critical product documentation—like Functional Specifications, Functional Descriptions, Interface Work Descriptions, signal/interface information, and radio capability parameters. The position is highly collaborative, working closely with Systems, Hardware, Software, Test, and Project Management teams to contribute to high‑quality deliverables. This role is well‑suited for early‑career engineers who want to deepen their understanding of radio systems, wireless technology, system design, and secure product development.
