Cloud Application Architect

Mission. Design and own how the platform runs on AWS: from a single host with Docker Compose to ECS across three availability zones, Aurora PostgreSQL, Valkey, zero-downtime deploys and autoscaling, and later a second region. You decide task sizes and memory limits, how gunicorn and Celery are laid out, how the database moves without a maintenance window, and how the whole thing fails over. You are hands-on in Terraform and pipelines, and you partner with the SRE team that operates what you design.

Reports to the Head of Platform and Reliability

What you will own
• Runtime architecture for the Django API and the Celery workers on ECS: task sizing, CPU and memory limits, worker and thread topology, health checks, graceful shutdown, rolling or blue-green deploys.
• The data tier: RDS to Aurora migration with near-zero downtime, RDS Proxy and IAM authentication, read replicas, backups, point-in-time recovery, cross-region replication.
• Cache and messaging:



Redis to Valkey on ElastiCache with replication; SQS and dead-letter queue hygiene; Kinesis capacity and consumer concurrency.
• Edge and network: ALB and NLB, WAF in block mode, per-merchant rate limiting, TLS, VPC design, private connectivity to providers, a multi-account landing zone with Organizations and SSO.
• Operations of the serverless estate: Lambda reserved and provisioned concurrency, canary deployments with alarms, dead-letter queues on every asynchronous path.
• Infrastructure as code and delivery: Terraform modules, GitHub Actions pipelines, environment parity, drift detection, rollback.
• Observability and cost: the Datadog APM rollout with the SRE team, SLO dashboards, capacity and cost visibility, Savings Plans and right-sizing.
• Resilience: load tests at 10x and 30x, game days, the disaster recovery plan with a tested runbook, the second-region design.
• PCI DSS infrastructure controls with the CISO: segmentation, hardening, logging, key management.
