Job Description

The role of IFS Principal Site Reliability Engineer – Performance Engineering (Principal-SRE) exists within the Unified Support organization/division and serves as a technical and strategic leader for Site Reliability Engineering practices. By being part of the shift operation and broader SRE leadership, a Principal-SRE will drive 24x7x365 support excellence to IFS customers across the globe within the Aerospace & Defense (A&D) industry vertical while establishing and elevating SRE practices across the organization. This role sits within a dedicated performance engineering team supporting our Ultra High Availability (Ultra HA) on Exadata customers, where sustained database and application performance is a contractual commitment rather than a best-effort goal.

As Principal SRE – Performance Engineering, you will be responsible for architecting and evolving the reliability frameworks, automation platforms, and operational strategies that underpin IFS's cloud-native products and infrastructure. This role involves setting technical direction, leading cross-functional teams, and partnering with R&D, Product, and Operations leadership to ensure that reliability is embedded at every level of service delivery. You will be an influential technical leader who drives organizational transformation through SRE principles, automation, and continuous improvement culture.

Strategic Impact Areas

• Reliability Architecture & Strategy: Define and evolve the SRE operating model for the A&D vertical, including incident management, capacity planning, and disaster recovery strategies. Architect resilience patterns and frameworks for cloud-based applications supporting critical Aerospace & Defense operations. Establish Service Level Objectives (SLOs) and Error Budgets aligned with customer contractual requirements and business objectives. Drive adoption of chaos engineering and resilience testing across production systems.
• Technical Leadership & Platform Engineering: Lead the design and implementation of enterprise-scale monitoring, observability, and automated remediation platforms. Establish and maintain infrastructure-as-code standards and CI/CD pipelines for reliable deployments. Champion modern SRE tooling and methodologies across Unified Support and R&D organizations. Define technical architecture for Kubernetes, multi-cloud orchestration, and cloud-native application patterns. Architect solutions for performance optimization, cost efficiency, and security at scale (3,200+ concurrent users, 6,048+ database connections).
• Ultra HA & Exadata Performance Engineering: Own the performance and availability posture of Ultra HA environments running on Oracle Exadata, including proactive database health monitoring, workload and wait-event analysis, and end-to-end application performance management. Establish deep observability across the Oracle stack and the application tiers it serves, using Elastic, Grafana, and OpenTelemetry-based instrumentation to correlate database behaviour with user-facing latency. Lead performance troubleshooting for the most demanding customer workloads and drive tuning, capacity, and remediation decisions ahead of SLA impact.
• Organizational Transformation & Culture: Drive automation-first culture, eliminating toil and enabling teams to focus on high-value, creative work. Lead post-incident reviews and establish blameless culture focused on systemic improvement. Mentor and develop SRE team members, establishing career progression paths and technical mastery standards. Establish communities of practice for knowledge sharing across Unified Support and R&D organizations.
