Top SchoolRoland Knall is a seasoned system engineer with 12 years of experience designing and implementing embedded and safety-critical software, currently working at ProfiTAP and long-standing as a core developer for the Wireshark project. He combines deep protocol and low-level networking expertise—demonstrated by contributions to Wireshark dissectors, extcap interfaces and openSAFETY tooling—with hands-on system architecture work in industrial automation and machine safety. Roland has led software teams, taught PLC development, and built SDKs and conformance tests for safety networks, bringing both leadership and practical implementation skills. He is comfortable across C/C++, Qt UI, and embedded stacks, and has a track record of refactoring complex UI/filter logic and improving capture capabilities in a major open-source project. Based in Salzburg, Austria, he pairs a pragmatic problem-solving mindset with persistence—treating setbacks as learning opportunities—and a reputation for quietly fixing tricky protocol bugs that affect real-world industrial systems.
