Security Engineer

Hudson River Trading (HRT) is seeking an experienced Security Engineer to join our Information Security team in Mumbai. In this role, you will help design, build, and maintain solutions that protect HRT’s global infrastructure, systems, and data within one of the world’s most advanced computing environments. You will have the opportunity to build and harness AI tools to solve cutting edge security problems. This is a senior-level, hands-on individual contributor role in cybersecurity, spanning both operations and compliance domains. 

From an operational standpoint, you will be responsible for detection engineering, threat hunting, incident response, cyber threat intelligence analysis, and adversary emulation exercises for our global infrastructure and systems.

• Help maintain HRT’s security detection and response program to protect our data and intellectual property from both internal and external threats
• Hunt for, detect, and respond to malicious activity and anomalous events on HRT’s devices and networks
• Conduct cyber threat intelligence research to identify relevant threat actors, and perform adversary emulation and purple teaming exercises 
• Investigate security events and support incident response, including any required regional coordination, documentation, and reporting
• Work an on-call rotation on a predefined schedule

Qualifications

• Strong troubleshooting, organizational, and project management skills, with the ability to independently drive work from problem definition through implementation
• Familiarity with security frameworks such as NIST, CIS, and SEBI CSCRF is preferred
• Experience working independently to deliver high-quality completed work
