## About the Role

* 5+ Years Experience: Proven seniority running live production AWS infrastructure independently.
 * Production Kubernetes Ownership: Hands-on EKS cluster operations (autoscaling, HPAs, resource constraints) and debugging runtime failures under pressure (OOMKills, rollout errors). Managed PaaS-only experience is not sufficient.
 * Advanced Terraform: Deep experience writing, modularising, and refactoring infrastructure definitions from scratch using Terraform and Terragrunt.
 * Relational Database Competence: Ability to read slow-query logs and analyze EXPLAIN plans to fix indexing or locking issues on Aurora MySQL.
 * Observability Depth: Strategic judgment to tune CloudWatch/Prometheus metrics so alarms page accurately at 3 AM rather than constantly.
 * Compliance Lead: Practical experience owning a SOC 2 or ISO 27001 audit programme.
 * Documentation Habit: Dedication to writing runbooks as a core engineering deliverable.

## Description

* Triage Aurora MySQL: Resolve our most common production bottlenecks-slow queries, lock contention, and connection pressure-by tracing faults directly back to application code or backend background queues.
 * Drive GitOps & Pipelines: Own the CI/CD release lifecycle end-to-end.
 * Manage On-Call Rota: Serve as primary on-call, with an external partner for escalation backup. (On-call rotation allowance and structured compensatory terms will be discussed at interview).
 * Maintain SOC 2 Compliance: Act as the lead point person for security audits, running access reviews, and administering Vanta.
 * Code: Write and review backend code (Python/Node.js) for internal orchestration tooling, microservices, and payment gateways.
