Position Overview:

The Site Reliability Engineer is based in North America (NAM) to serve as the regional pillar of our global reliability engineering function within Markets Technology. In this role, you will be part of a distributed, high-impact three-person global team, working closely with your counterparts in EMEA and APAC to provide resilient, round-the-clock ("follow-the-sun") operational excellence, infrastructure automation, and architecture reliability for mission-critical enterprise systems.

As a VP-level Individual Contributor, you will operate as a technical authority for the NAM region. You will champion modern SRE principles—bridging software engineering, systems architecture, and production operations—to maximize service uptime, optimize performance, and drive end-to-end automation across hybrid-cloud and on-premises environments.

Key Responsibilities:

Reliability Engineering, Observability & Incident Governance

• SLO/SLI Framework Ownership: Define, monitor, and enforce Service Level Indicators (SLIs), Service Level Objectives (SLOs), and Error Budgets across core regional and global platforms in collaboration with development and product teams.
• Incident Management & Root Cause Elimination: Act as the Tier-3 technical escalation authority for critical production incidents during NAM market/operational hours. Conduct blameless Post-Incident Reviews (PIRs) and implement preventative architectural and automated remediations.
• Advanced Observability: Design and maintain unified monitoring, logging, tracing, and alerting ecosystems (e.g., Prometheus, Grafana, OpenTelemetry, Splunk, Dynatrace, Datadog) to ensure deep system telemetry and proactive anomaly detection.

Automation, Infrastructure as Code (IaC) & Continuous Delivery

• Toil Elimination: Identify repetitive operational tasks and eliminate toil through software engineering, creating resilient tools, automated runbooks, and self-healing infrastructure.
• Infrastructure as Code & Configuration: Architect, provision, and maintain secure, highly available cloud and bare-metal environments.
• CI/CD Pipeline Reliability: Partner with application engineering teams to design robust, secure, and automated release deployment patterns (Canary, Blue/Green, Feature Flags) that minimize change failure rates and deployment friction.

Global "Follow-the-Sun" Collaboration & Hand-Offs

• Global Continuity: Execute structured, high-context operational and incident handoffs with counterparts in EMEA and APAC, ensuring seamless 24/7 reliability coverage without requiring overnight on-call shifts.
• Global Standardization: Align regional operational standards, automation scripts, and disaster recovery procedures with the global pod to maintain parity across regions.
• Regional Change & Regulatory Windows: Oversee critical change execution, patching, and deployment windows specific to the NAM time zone and regulatory environment.

Architectural Resilience, Chaos Engineering & Capacity Planning

• Resiliency by Design: Partner with Solutions Architects to review system designs against non-functional requirements (NFRs), high availability (HA), and multi-region failover capabilities.
• Capacity & Cost Optimization: Forecast infrastructure capacity requirements based on business traffic growth patterns, optimizing compute, storage, and networking utilization across NAM data centers and cloud zones.

Qualifications:

Experience

• Experience Level: 6+ years of professional experience in Software Engineering, DevOps, Cloud Architecture, or Systems Engineering, with at least 4+ years dedicated to Site Reliability Engineering (SRE) or Production Engineering at a senior/lead level.
• Industry Background: Prior experience in highly regulated, mission-critical, or high-throughput environments (e.g., Financial Services, FinTech, Tier-1 Tech, Enterprise SaaS) is strongly preferred.

Technical Competencies

• Software Development / Scripting: Advanced proficiency in at least one core programming language (Python, Java,) and shell scripting (Bash) for tooling, automation, and API integration.
• Cloud & Container Orchestration: Deep expertise with Kubernetes (OpenShift), Docker, and enterprise cloud platforms (AWS).
• Infrastructure as Code (IaC): Extensive experience writing and maintaining modular Terraform, CloudFormation, or Ansible codebases.
• Operating Systems & Networking: In-depth knowledge of Linux/Unix internals (kernel tuning, I/O bottlenecks, memory management), networking fundamentals (TCP/IP, BGP, DNS, Load Balancing, TLS/mTLS, HTTP/gRPC), and distributed system failure modes.
• Database & Storage Systems: Familiarity with relational databases and distributed data stores/messaging systems from a reliability, backup, replication, and failover perspective.
• Observability Tooling: Hands-on experience configuring and scaling telemetry stacks.

Leadership & Interpersonal Attributes (Individual Contributor)

• High Autonomy & Ownership: Demonstrated capability to operate independently as the sole regional subject matter expert while maintaining strong synergy with global peers.
• Communication & Stakeholder Management: Exceptional written and verbal communication skills; ability to articulate complex technical issues and trade-offs to senior leadership and cross-functional engineering teams.
• Problem-Solving & Bias for Action: Calm under pressure during high-severity production incidents, with an analytical mindset focused on data-driven decision-making.

Key Performance Indicators (KPIs)

• Mean Time to Detect (MTTD) & Mean Time to Resolve (MTTR) across NAM service components.
• Service Availability & SLO Attainment against target thresholds.
• Toil Reduction Rate: Quantifiable percentage of operational tasks automated and transitioned to self-service.
• Change Failure Rate & Rollback Frequency: Reduction in deployment-related service disruptions.
• Quality of Global Handoffs: Zero-drop continuity across NAM/EMEA/APAC shift transitions.

Education:

• Bachelor’s degree/University degree or equivalent experience
• Master’s degree preferred
