• Execute eFuse programming procedure
• Fusing ED25519 public key hashes into write-protected OTP memory banks using hardware JTAG interfaces 
• Operate the parallel out-of-band (OOB) node flashing engine
• Managing simultaneous image deployments across all 48 nodes per chassis 
• Configure and validate the automated A/B partition watchdog and boot recovery chain 
• Monitor and log TSADC thermal sensor data from compute nodes to the BMC management interface 
• Maintain version-controlled firmware repositories with clear change documentation.
