Senior Information Security Engineer

Make Your Mark:

Reporting to the Senior Director of Information Security, the Sr. Information Security Engineer will play a lead role in executing security strategy and consulting on best-in-class security architecture and security posture for BlackLine. In this role you will provide on-call duties, manage/triage ticket queues, review access requests, review architecture, implement security solutions, collaborate with cross-functional teams, perform vulnerability management functions, and execute the evolution of Blackline’s Enterprise Information Security components.

You'll Get To:

• Participate in a 'follow-the-sun' on-call schedule, acting as the primary responder during the India shift to monitor, triage, and manage the security alerts queue.
• Bridge the gap between research and remediation by developing manual runbooks (SOPs) and automated playbooks needed to handle threats and eliminate noise.
• Establish the operational scope and testing boundaries for security assessments and penetration tests, focusing on targeted risk discovery and impact.
• Apply a research-first mindset to incident response, demonstrating the critical thinking needed to independently triage threats and figure out new tools across a varied security landscape.
• Operationalize security infrastructure through Terraform, with the foundational knowledge to independently research and implement automation across various providers and platforms.
• Manage the operation of key security technologies, including Endpoint Detection and Response (EDR), Data Loss Prevention (DLP), and Web Application Firewalls (WAF).
• Leverage AI and LLMs to accelerate security analysis, automate repetitive tasks, and drive operational efficiency across the security stack.
• Flex into evolving security initiatives and technical projects as they arise, taking ownership of tasks that fall beyond the initial scope of this role.
• Define effective information security standards applicable to specific environments.
• Create and maintain operational reports and security metrics, translating raw data into the technical insights required for data-driven decision-making.
• Serve as a technical leader and mentor, providing guidance to junior engineers and collaborating with cross-functional teams on security best practices.

What You'll Bring:

• 5+ years of hands-on information security experience, including 1 year of experience managing Web Application Firewalls (WAF).
• Practical experience with cloud security platforms like SCCE, AWS Security Hub, or Azure Security Center, and the technical "scrappiness" to research and utilize new security services across a multi-cloud environment.
• Strong problem-solving and analytical skills with the ability to identify security risks and propose effective solutions.
• Highly autonomous and productive in performing activities, requiring minimal direction from management.
• Proven ability to leverage scripting languages, such as Python, Bash, and PowerShell, to interface with applications and/or available APIs.
• Expertise in Windows and with a working knowledge of Linux/Unix (advanced Linux skills are a big plus).
• Working knowledge of network security-through understanding of the OSI model and comprehensive knowledge of common protocols and services for levels 3 through 7.
• Advanced written and verbal communication skills including the ability to present technical subjects to non-technical audiences.
• Maintain technical depth in common vulnerabilities and exploitation techniques to independently research, triage, and remediate complex security findings.

We’re Even More Excited If You Have:

• Experience in securing Kubernetes and containers.
• Hands-on experience with securing AI systems and LLMs.
• Working knowledge of WMI and WSH in a modern security context.
• Utilize outside the box thinking to define new and improved solutions or optimize current processes and tools.
