Why we read it this way (6)
The communication interfaces (SPI, I2C, I2S, UART, CAN, USB, BLE, Wi-Fi, Ethernet) are listed together as a single knowledge requirement; each has been extracted as a separate skill for granularity.
The Atlassian toolset is mentioned in the context of the Agile work environment; Jira is used as the canonical representative of that suite.
I2S was omitted from the skills list as it is a less common variant listed alongside the others; it can be added if desired.
C++ and IoT are described with 'working knowledge' — a softer gate than the firm requirements for C and microcontroller experience, so they are marked preferred.
ARM Cortex-M4/M7 and TrustZone are explicitly called out as 'familiarity' items, placing them under preferred.
Up to 20% travel is required — not captured in any structured field but worth noting for candidates.
