Cover Letter Sample

Dear Hiring Manager,

I am excited to apply for the Vulnerability Operation Center Lead position at Nebius. With over 7 years of experience in information security and a strong focus on vulnerability management, I have a proven track record of building and leading teams that drive effective remediation. I am particularly drawn to the opportunity to design and implement a new VOC from the ground up, aligning with Nebius's innovative AI cloud infrastructure.

In my previous role, I led vulnerability triage and remediation for a large cloud environment, reducing mean time to remediate by 40% through process automation and cross-team collaboration. I have deep expertise in risk-based prioritization frameworks like CVSS, EPSS, and SSVC, and I am adept at integrating threat intelligence feeds to improve data quality.

I am confident that my hands-on experience with cloud-native environments and my strategic approach to vulnerability management will enable me to make an immediate impact at Nebius. I look forward to the opportunity to discuss how I can contribute to your team.

Sincerely,
[Your Name]

Sample Interview Questions

How would you approach building a vulnerability management program from scratch in a cloud-native environment?

I would start by understanding the organization's assets and risk appetite, then define a vulnerability management policy. I'd select tools for scanning and prioritization, establish a triage process, and set up metrics like mean time to remediate. Automation and integration with existing workflows would be key to scalability.

Describe a time you had to drive remediation for a critical zero-day vulnerability across multiple engineering teams.

In my previous role, a critical zero-day in a widely used library required immediate patching. I coordinated with engineering to identify affected systems, prioritized based on asset criticality, and established a war room. We patched all critical systems within 48 hours and improved our zero-day response playbook.

How do you prioritize vulnerabilities when dealing with thousands of findings?

I use a risk-based approach combining CVSS, EPSS, SSVC, and asset criticality. I filter out false positives using contextual data and automation. I also consider exploitability and business impact, and I work with stakeholders to adjust priorities based on their feedback.

What metrics would you track to measure the effectiveness of a vulnerability management program?

Key metrics include mean time to detect (MTTD), mean time to remediate (MTTR),% of vulnerabilities patched within SLA, vulnerability backlog count, and false positive reduction rate. I also track trends in critical vulnerability discovery and remediation velocity.

How would you integrate threat intelligence feeds into your vulnerability triage process?

I would ingest feeds from sources like CISA, threat intelligence platforms, and crowd-sourced data. I'd correlate them with our asset inventory and prioritize vulnerabilities associated with active exploits. Automation can enrich findings with exploitability context and trigger alerts for high-risk items.

Vulnerability Operation Center

The team maintains the full vulnerability management lifecycle – from detection and triage through remediation tracking and reporting – across Nebius’s cloud infrastructure, product, and hardware stack. The team’s focus is on improving vulnerability triaging capabilities and vulnerability data quality, driving effective remediation, and serving as the first line of response for the most critical zero-day vulnerabilities.

The role

We’re building a Vulnerability Operations Center from the ground up and need a senior practitioner to lead it. You’ll own the full vulnerability management lifecycle – from detection through triage to remediation tracking and reporting – across Nebius’ cloud infrastructure, product and hardware stack. This is a high-impact role with big ownership: you’ll define processes, select tooling, work directly with engineering teams, and set the standard for how Nebius responds to vulnerabilities.

What You’ll Do

Improve and maintain automated vulnerability triaging capabilities and vulnerability data quality through data enrichment (internal and external intelligence feeds), quality metrics, AI-assisted triage, context-aware risk scoring, and vulnerability correlation/chaining.
Hands-on validation and triaging of most critical/zero-days vulnerabilities
Work closely with vulnerability data consumers and stakeholders across the organization to meet engineering, compliance, and regulatory requirements by delivering high-quality, actionable findings and driving effective remediation.
Contribute to the development of internal platforms, including the Unified Vulnerability Management (UVM) system and the security orchestration platform, to automate core vulnerability management workflows and reduce manual effort.
Identify current deficiencies in patch management, drive and oversee improvements across engineering teams and business units to improve remediation efficiency and reduce organizational risk
Own vulnerability intake from all sources – scanners, bug bounty, threat intel feeds, and penetration tests
Prioritize findings using risk-based frameworks (CVSS, EPSS, SSVC, asset criticality, exploitability context, business impact) and reduce false positive noise
Drive remediation accountability across infrastructure, platform, and product engineering teams
Identify, track and report vulnerability management metrics, present KPIs and trends to security leadership
Coordinate response to critical/zero-day vulnerabilities, acting as the primary point of contact across security, engineering, and operations
Define and maintain integration between VOC tooling and the broader security ecosystem.

What We’re Looking For

5–8 years in information security with at least 3 years focused on vulnerability management or security operations
Deep familiarity with vulnerability scanning tools and their strengths/limitations in cloud-native environments
Strong grasp of CVE/NVD, CVSS scoring, EPSS, SSVC and how to apply them to real-world prioritization
Experience managing vulnerabilities across IaaS/cloud infrastructure (AWS, GCP, Azure, or private cloud) – experience with GPU/HPC environments is a plus
Deep understanding of vulnerability sources limitations and corner cases for different vulnerability classes
Able to write and review code (ability or willingness to develop in Golang) – well enough to assess exploitability, validate fixes, and build lightweight automation (e.g., variant-detection scripts, triage tooling, data pipelines for trend analysis)
Strong grasp of common vulnerability classes at the code and infrastructure level.
Comfortable feeding well-documented vulnerability patterns into AI-assisted code review workflows and critically evaluating the output
Track record of working cross-functionally with engineering teams and holding stakeholders accountable to timelines without being a bottleneck
Strong written and verbal communication – able to translate technical risk into business impact for non-security audiences

Nice to Have

Experience building vulnerability management program from scratch
Familiarity with container and Kubernetes security
Experience with supply chain security (SBOMs, dependency scanning)
Bug bounty triage experience
Public talks or research articles
