Position Overview

Our client's payments infrastructure spans two clouds and two very different eras of application architecture: a VM-based Azure estate needing security hardening and modernization, and a modern AWS-based events platform. The SRE function is newly combined and growing, bringing together infrastructure ownership that used to be spread across teams. This is a chance to bring individual systems under real operational management: instrumenting them, documenting them, and securing them. You'll work alongside a Staff SRE who sets the team's overall technical direction.

Key Responsibilities

• Bring individual systems in the Azure and AWS estates under management: instrumentation, monitoring, documentation, and runbooks
• Support Azure security remediation: RBAC cleanup, privileged-access review, and network exposure fixes
• Operate and support the AWS-based events platform, including ECS-based services and Lambda/Step Functions workflows
• Contribute to CI/CD and release-safety improvements
• Take a seat in the shared, limited-hours on-call rotation for the events platform
• Use AI-assisted development tools in a practical, controlled way, with human review as the final gate before anything ships

Required Qualifications

• 8+ years of overall engineering experience, including solid experience as a Senior SRE or equivalent, operating production infrastructure at scale
• Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience
• Hands-on PCI compliance experience: familiarity with PCI-DSS requirements and PCI-aware production operations
• Deep Azure experience required (legacy, VM-based environments)
• Working knowledge of database operations (SQL Server and/or a managed relational database such as Aurora MySQL) sufficient to diagnose performance and reliability issues
• Deep observability knowledge: monitoring, alerting, dashboards, and incident response, including in-depth, hands-on experience with at least one event-based observability platform (Datadog, Honeycomb, New Relic, or comparable)
• Experience with Azure DevOps (ADO) or similar CI/CD tooling
• Deep familiarity with Infrastructure-as-Code, including hands-on expertise with at least one IaC language (Terraform, Crossplane, OpenTofu, CDK, CloudFormation, or Bicep)
• Enough software fluency to read and debug application code, and to separate infrastructure symptoms from application-level defects
• Experience modernizing legacy .NET systems and the infrastructure underneath them Proficiency with Claude Code, Codex, or comparable AI-assisted development tools

Preferred Qualifications

• Experience with automated testing frameworks
• Experience with event-driven or queue-based AWS architectures (EventBridge, Lambda, Step Functions, DynamoDB)
• Experience joining a newly combined or fast-growing infrastructure team and helping bring it under a more consistent structure
