Siemens Gamesa

Location
Siemens Energy’s location in One Cotroceni Park is more than just an office space - it’s a hub for a vibrant and growing community. Nestled in the heart of Bucharest, this urban development is the perfect place to work, surrounded by green spaces, shopping destinations, and everything the city center has to offer. And with the Academia Militara subway station just a 3-minute walk away, getting around the city has never been easier.

A Snapshot of Your Day
Join us as an OT Security Analyst in our Central Security Operations Center (cSOC), where you will play a crucial role in safeguarding industrial control systems (ICS) from cybersecurity threats. Imagine being at the forefront of monitoring, detecting, and analyzing security events that impact industrial networks, PLCs, DCS, and SCADA environments. You will collaborate with SOC operations, OT engineering, and incident response teams to ensure that security incidents are identified early and managed effectively, all while maintaining operational continuity and safety. Your expertise will be vital in driving innovation and resilience in our cybersecurity efforts.

How You’ll Make an Impact

• Continuously monitor OT environments using SIEM, NDR, and specialized ICS monitoring tools to detect potential threats, ensuring the integrity and security of critical systems.
• Correlate events from various OT data sources, including Syslog, PLC alarms, and network telemetry, to identify anomalies such as unauthorized changes or suspicious protocol activity, escalating alerts based on severity models that prioritize safety and operational continuity.
• Analyze OT network traffic and logs, utilizing your knowledge of industrial protocols to investigate suspicious activities, ensuring that any deviations from established baselines are addressed promptly and effectively.
• Act as the first line of response for OT security incidents, coordinating with engineers and site operations to validate alerts, safely isolate affected network segments, and contain threats without disrupting critical processes or production.
• Produce detailed security reports and maintain documentation for detection logic and compliance, supporting internal and external audits while providing insights into threat trends and operational impacts.
• Collaborate with cross-functional teams to enhance security measures, sharing your expertise in vulnerability management and threat intelligence integration to support patching and mitigation decisions that balance operational risk with threat severity.
• Continuously improve detection capabilities by tuning SIEM and NDR systems, developing custom correlation rules, and defining OT-specific detection playbooks that empower the team to respond effectively to emerging threats.

What You Bring

• Strong understanding of ICS/OT architectures and industrial processes, with hands-on knowledge of PLC, DCS, and SCADA systems.
• Expertise in industrial communication protocols (e.g., Modbus, PROFINET, OPC UA) and experience with SIEM and NDR tools will be essential.
• Ability to analyze packet captures with an OT-specific context and are familiar with IEC 62443 requirements.
• Strong analytical and documentation skills enable you to produce incident and compliance reports effectively.
• You are a collaborative team player, capable of working with OT, automation, and network teams to enhance security measures.
