Senior AWS DevOps Engineer to investigate and fix a deployment issue

Our production stack lives entirely in AWS, centered on EC2 instances, S3 storage and a growing set of Lambda functions. Day-to-day deployment, scaling and maintenance are starting to slow us down, so I want a Senior DevOps engineer to step in and automate the repetitive work while tightening up reliability.

A few key things you will tackle
• Turn the manual EC2, S3 and Lambda setup into clean, version-controlled Infrastructure.
• Design or refine a CI/CD pipeline that can push code to all three services with zero-downtime blue/green or canary style releases.
• Bake in logging, metrics and alerting as you go so we have instant visibility of failures or performance drifts.
• Document everything clearly enough that a new team member can spin up the entire environment from scratch without guesswork.

Acceptance criteria
1. A single command (or pipeline trigger) provisions the full stack in a new AWS account.
2. Rollbacks happen automatically if a deployment step fails.
3. EC2, S3 and Lambda resources are tagged and configured to AWS best-practice security standards.
4. Clear README or runbook supplied.
