📋 Description

• Own 5 AWS accounts across the organisation (QA, Prod, Infra, plus two others) • Architect and maintain infrastructure as code with Terraform. Replace the click-ops that's still around • Stand up CI/CD pipelines engineers actually want to use. Blue/green and canary where it makes sense • Run releases reliably and reduce key-person risk on the deploy process • Set up monitoring, alerting, and incident response so we catch issues before customers do. • Define SLIs and SLOs that map to real user journeys • Lead incident response as the primary infra responder. • Run blameless post-mortems • Patch and harden the platform. We're a fintech, this matters. IAM least privilege, secrets management, vulnerability scanning, MFA enforcement • Lead infrastructure work for the TV launch: traffic spikes, autoscaling, capacity planning, runbooks • Partner with backend engineers when production issues cross into the app tier. JVM tuning, connection pools, async patterns, memory leaks • Architect multi-region DR. • Drive the platform toward self-healing • Optimise cost across DynamoDB, Lambda, and the wider AWS footprint • Set architectural guardrails with tech leads and SWEs. • Mentor engineers as the platform capability grows.

🎯 Requirements

• 6+ years hands-on AWS in production (VPC, IAM, EC2/ECS/EKS, Lambda, S3, CloudFront, Route53, RDS, DynamoDB, SQS) • Production Terraform (Terragrunt a plus). Multi-environment state management • Production Kubernetes and Docker. EKS specifically • Strong CI/CD experience: GitHub Actions, GitLab, Jenkins, or ArgoCD. GitOps practices • Strong infrastructure security: IAM least privilege, secrets, patching, vulnerability scanning, MFA enforcement • Observability from scratch: CloudWatch, Datadog, Grafana, Prometheus, OpenTelemetry, or ELK • Solid backend competency in Java (Spring Boot), Python, or Node. • Understanding of JVM, concurrency, async systems • Comfort being the senior infrastructure person. Self-directed, opinionated, disciplined about documentation • B2/C1 Level English. • Nice to have Fintech or other regulated industry experience • DynamoDB at scale (we run many tables with PITR and S3 exports, Lambda-driven daily incrementals) • AWS cost optimisation track record • Past experience as a first infrastructure hire at a small team • Building internal developer platforms or self-service tooling • AWS DevOps Pro, Solutions Architect Pro, or CKA • Service mesh experience (Istio, Linkerd) and DevSecOps practices • Firebase or GCP exposure (we have a small footprint there).
