Come work at a place where innovation and teamwork come together to support the most exciting missions in the world!

The Lead Site Reliability Engineer is the technical leadership tier of the Qualys SRE ladder — the level where operational excellence, reliability engineering, and technical leadership converge. While Senior SREs focus on improving individual services and platforms, the Lead SRE drives reliability strategy across multiple systems, teams, and operational domains.

You will lead initiatives that improve scalability, resilience, automation, and operational maturity across Qualys cloud platforms. This role requires strong technical judgment, deep expertise in distributed systems, cloud-native architectures, observability, automation, and incident management, along with the ability to mentor engineers and influence cross-functional teams.

Dimension 

Lead SRE Expectation 

Ambiguity 

Moderate to High — translates broad reliability objectives into scalable operational solutions. 

Scope 

Multiple applications, platforms, and infrastructure domains across the organization. 

Ownership 

Technical leadership for reliability, observability, automation, and operational excellence initiatives. 

Judgment 

Balances reliability, security, scalability, performance, and cost trade-offs. 

Business Impact 

Significant — improves customer experience through higher availability, faster recovery, and reduced operational risk. 

• Lead the design, implementation, and maintenance of highly scalable, reliable, and secure cybersecurity cloud platforms.
• Define and implement reliability engineering best practices, standards, and operational processes.
• Participate in capacity planning, disaster recovery planning, and business continuity initiatives.
• Drive operational excellence programs that improve platform resilience and reduce operational risk.

• Drive automation initiatives for infrastructure provisioning, deployments, monitoring, and incident management.
• Architect and optimize CI/CD pipelines and deployment strategies.
• Reduce operational toil through automation and self-service capabilities.
• Evaluate and adopt new technologies that improve operational efficiency and reliability.

• Lead incident response, root cause analysis (RCA), and postmortem reviews for critical production issues.
• Establish and manage SLIs, SLOs, and SLAs across services and platforms.
• Evaluate and implement monitoring, logging, tracing, and observability solutions.
• Establish reliability metrics and operational KPIs to drive continuous improvement.

• Collaborate with software engineering teams to improve application reliability, performance, and scalability.
• Mentor and guide SRE, DevOps, and platform engineering team members.
• Partner with security teams to ensure infrastructure compliance and operational security.
• Participate in leadership discussions regarding infrastructure strategy and technology adoption.
• Drive cross-functional collaboration between engineering, security, and operations teams.

• Leads reliability initiatives that measurably improve availability, performance, and operational efficiency.
• Anticipates system-level risks and drives preventive engineering solutions.
• Builds automation that significantly reduces operational overhead and incident frequency.
• Leads major incident investigations and drives long-term corrective actions.
• Influences engineering teams to adopt reliability-first and automation-first practices.
• Develops engineers through mentorship, coaching, and technical leadership.
• Serves as a trusted technical leader during critical operational and architectural decisions.

The Lead SRE is not measured solely by operational execution or incident response effectiveness. This role is measured by its ability to elevate the reliability maturity of systems, improve engineering practices, and create scalable operational solutions that benefit multiple teams. A successful Lead SRE creates lasting impact through technical leadership, automation, and operational strategy.
