Summary
🤩
Rockstar🎓
Top SchoolTom Llewellyn-smith is a seasoned information security and operations leader with 13 years of hands-on experience building and securing production infrastructure across the UK and San Francisco Bay Area. Currently CISO at Voltage Park after progressing from VP of Security, he has deep Unix, SRE, and systems-architecture roots from long tenures at Stellar Development Foundation and multiple consultancy roles. Tom blends low-level systems expertise—AIX, Linux, BigIP/iRules—with strategic security leadership, running cross-functional programs that connect engineering, ops, and risk. He’s comfortable transitioning between contractor pragmatism and executive stewardship, having led teams and client engagements from startup to foundation scale. An unconventional background in literature and multilingual studies informs his clear communication of complex technical concepts to non-technical stakeholders. Known for steady, practical problem-solving, he favors auditable, repeatable solutions over flashy one-offs.
