Urgent: Need a senior QRadar engineer who has personally performed Event Processor disaster recovery, Ariel data migration between EPs, and version-mismatched managed host rejoin. Hands-on experience required — not theoretical knowledge.

The engineer will be expected to perform one of two recovery paths (we will decide together based on assessment):

PATH A — Rebuild and rejoin:
- Safely extract or protect the existing /store/ariel data on the failed host
- Perform a factory reinstall or fresh install of QRadar on the failed hardware
- Correctly preserve the existing Ariel database during reinstall
- Apply the required Update Package SFS to version-match the rest of the deployment
- Rejoin the host to the Console as a managed host with the original identity
- Verify historical Ariel data is searchable through the Console after rejoin

PATH B — Data migration and consolidation:
- Mount the recovered /store array from rescue mode
- Migrate the Ariel database (events, payloads, indexes) to a surviving Event Processor
- Apply correct procedures to make the migrated historical data searchable on the destination EP
- Decommission the failed host cleanly from the deployment without losing data references

REQUIRED EXPERIENCE
===================

Must have personally and successfully performed ALL of the following on production QRadar deployments:

1. QRadar Event Processor rebuild on software installs (not just appliances). Must understand the difference between 'retain' and 'flatten' install options, how partition layouts behave on software installs vs. appliance installs, and how to safely preserve /store during a reinstall when OS and /store share physical disks.

2. Ariel database migration between hosts. Must have moved or merged Ariel data (records, payloads, indexes) from one EP to another, including any required catalog rebuilds, file ownership corrections, and Console-side reconciliation steps. Must explain the exact procedure they have used before.

3. SFS-based version upgrades, including applying Update Package SFS files via patchInstaller, handling pre-upgrade checks, code-signing verification, secure boot key import, and recovering from interrupted SFS installs.

4. Managed host re-registration with the Console — including version-mismatched rejoin, hostname/IP/identity preservation, and the implications of 'Remove Host' vs. 'Disable' vs. 'Edit Host'.

5. Deployment Editor and System and License Management operations — repointing Event Collectors, license reallocation, configuration replication, deploy troubleshooting, and resolving 'deployment is required' / 'host status unknown' states.

6. QRadar internal architecture and CLI — including service ordering for ecs-ec, ecs-ep, hostcontext, tunnel_manager, ariel_proxy; reading qradar.log and deployment logs; debugging EC-to-EP forwarding paths.

7. LVM and XFS recovery in Linux — pvs/vgs/lvs operations, xfs_repair, mounting recovered volumes from rescue environments, rsync/dd-based block-level data movement.

I’m looking for an experienced AWS DevOps / production engineer to help take an existing Node/Postgres clinical portal from local prototype/private demo staging toward a secure AWS deployment.

The immediate goal is to stabilize a private demo-data-only staging environment. The longer-term goal is to prepare a production architecture that can later be reviewed for PHI/HIPAA-oriented use after legal/compliance signoff.

The app currently uses:

Node 24
Prisma
PostgreSQL
GitHub Actions
Local PDF/report storage
Existing AWS staging planning docs
Existing CI and AWS deployment workflow

This first engagement should focus on discovery, deployment stabilization, and a clear technical plan. I would like to start with a smaller paid milestone before expanding the scope.

Initial deliverables may include:

Review the GitHub repo and current AWS setup
Stabilize the private demo-data-only staging deployment
Recommend App Runner vs. ECS/Fargate for production
Set up or improve CI/CD through GitHub Actions
Avoid long-lived AWS access keys, preferably using GitHub OIDC
Review RDS PostgreSQL setup and recommend production structure
Review private S3 storage path for PDFs/reports
Review secrets management using Secrets Manager or SSM
Confirm CloudWatch/CloudTrail logging approach
Identify risks, gaps, and next steps
Produce concise documentation/runbook notes

Experience with HIPAA-oriented, healthcare, or PHI-adjacent AWS environments is strongly preferred. This role does not require the developer to certify HIPAA compliance, but the infrastructure should be built with compliance review in mind.

Relevant experience:

AWS production deployments
DevOps / cloud architecture
Terraform, AWS CDK, or CloudFormation
Docker / containerized deployments
GitHub Actions
GitHub OIDC to AWS
Node.js applications
PostgreSQL / RDS
Amazon S3 private file storage
AWS Secrets Manager or SSM Parameter Store
IAM least privilege
CloudWatch / CloudTrail
Monitoring, backups, and restore procedures
Security-oriented deployment practices

Please include in your proposal:

Whether you recommend App Runner or ECS/Fargate for this type of app
Your experience with AWS healthcare, HIPAA-oriented, or security-sensitive projects
Your experience with GitHub Actions OIDC to AWS
Your experience with RDS PostgreSQL and private S3 file storage
Suggested first milestone
Estimated timeline and cost for the first milestone
Any risks or concerns you see from the project description

The ideal first milestone is discovery + staging stabilization + AWS deployment assessment. If that goes well, there may be a larger follow-on engagement to build out the production-ready environment.

Background:
I'm Tim Clue — a humor-based speaker who works with schools and organizations (timclue.com). I send weekly Constant Contact emails to superintendents and principals and want to make sure those emails are landing in inboxes, not spam folders.

What I've already done:
Before posting this job, I ran a DNS diagnostic on timclue.com using MXToolbox. Here's what I found:

- MX records: Routing correctly through Microsoft 365 ✓
- SPF record: Valid and passes all checks, but Constant Contact (spf.constantcontact.com) is NOT included — only M365 and Mailchimp are authorized ✗
- DMARC: Set to p=quarantine; pct=100 with strict alignment — meaning unauthorized senders like Constant Contact could be getting quietly quarantined ✗
- DKIM for Constant Contact: Unknown — needs verification

Current SPF record:
v=spf1 include:spf.protection.outlook.com include:servers.mcsv.net ~all

What needs to be done:
1. Add include:spf.constantcontact.com to the SPF record
2. Add the correct Constant Contact DKIM record(s) to DNS
3. Confirm Microsoft 365 sending is unaffected after changes
4. Verify the fix — confirm Constant Contact passes SPF and DKIM alignment under our DMARC policy
5. Provide a short plain-English summary of what was changed and why

Important constraints:
- DNS is hosted on Squarespace
- Make no changes outside of email authentication records without prior approval
- This is a small, surgical job — not a broad DNS overhaul

Goal:
We're not sure Constant Contact is currently failing — but given the strict DMARC and missing SPF/DKIM entries, we want to ensure proper authentication as a proactive deliverability step before our next campaign goes out to school administrators.

Ideal fit:
- Experienced with DNS email authentication (SPF, DKIM, DMARC)
- Familiar with Constant Contact and Microsoft 365
- Comfortable working carefully within a narrow, defined scope

Budget / Timing:
Fixed price: $150
Bonus: $50 if completed within 3 days and M365 email remains unaffected

Possible next step:
I'm also beginning a larger transition from Squarespace to WordPress, so there may be future DNS/hosting guidance work — but let's start here first.
