Site Reliability Engineer, Principal

Synopsys is hiring a Principal Site Reliability Engineer to lead enterprise capacity strategy and reliability across on-premises and cloud infrastructure. The role focuses on forecasting demand, guiding infrastructure investments, improving automation and observability, and coordinating response to major infrastructure events.

Responsibilities:

• Own the enterprise capacity strategy and roadmap across compute, storage, network, and cloud to ensure scalable, resilient growth
• Lead long-range demand forecasting and scenario planning, translating business direction into clear infrastructure investment recommendations
• Build executive-ready dashboards and narratives that connect utilization, performance, availability, and cost trends to actionable decisions
• Architect and deliver automation that improves capacity planning accuracy, reduces operational toil, and prevents recurring reliability issues
• Establish governance mechanisms—standards, planning cadences, and prioritization workflows—that align teams on resource allocation and service commitments
• Drive reliability improvements by defining and operationalizing SLOs, strengthening observability, and proactively mitigating scalability and capacity risks
• Lead response and follow-through for major infrastructure events, ensuring rapid stabilization and durable root-cause elimination

Requirements:

• You have deep, hands-on understanding of enterprise infrastructure across compute, storage, networking, and cloud, and you can reason about how changes in one domain affect reliability in another
• You bring a strong quantitative mindset, using statistical thinking, forecasting, and structured analysis to turn messy operational data into clear recommendations
• You have a track record of defining meaningful SLIs/SLOs, instrumenting services for observability, and building alerting that drives action rather than noise
• You bring a proactive reliability approach, designing automation and guardrails that prevent recurring issues and reduce operational toil
• You have led large, cross-functional infrastructure initiatives end-to-end, aligning stakeholders and delivering outcomes through ambiguity and competing priorities
• You communicate with clarity and influence, tailoring technical depth to the audience and building executive-ready narratives that support investment decisions
• You bring a continuous-improvement mindset, challenging the status quo and simplifying processes to raise service maturity over time
• You are at your best in ambiguity, turning incomplete inputs into clear options, tradeoffs, and next steps without waiting for perfect data
• You approach problems with disciplined curiosity, digging past symptoms to understand system behavior and prevent repeat failures
• You are skilled at aligning diverse stakeholders, translating between engineering details and business priorities to drive timely decisions
• You communicate with precision and calm during high-pressure moments, keeping teams focused on restoration, learning, and follow-through
• You are intentional about simplification, consistently reducing toil and process friction so teams can operate reliably at scale
