Manage anomalies by reporting observations in Jira and investigating issues on SatSims and hardware. Identify and report any discrepancies between SatSims and Hardware to improve simulator representativeness. Upload test sessions to internal tools and maintain full test traceability. Develop offline processing tools to automate manual operations (using Java, Python, etc.). Perform base operations with lab equipment such as DC power supplies, RF signal generators, and spectrum analysers. Work within Linux OS environments and manage source code/versioning with GIT/SVN.
