Day-to-Day Responsibilities
Design the main circuit board and place components such as the processor, memory, power management and sensors.
Work with PCB layout engineers to route high-speed signals and keep power clean and stable.
Design or tune antennas and radio parts so calls, 5G, Wi-Fi and Bluetooth work well inside a thin metal or glass body.
Plan the internal layout of the battery, charging path and thermal parts so the phone stays cool and safe.
Work with mechanical and industrial designers on the frame, hinges (for foldables), camera module mounts and casing.
Build and test prototypes, running drop, temperature, water-resistance and electromagnetic interference tests.
Review designs with factory and supplier teams to check they can be built reliably and at a reasonable cost.
