Job#: 3021025

Job Description: AWS Network Firewall Engineer x2

Location: Hybrid from Mclean, VA;
Plano, TX or Richmond, VA

Contract: through end of the year

We’re looking for a hands‑on engineer who has designed, implemented, and operationalized AWS Network Firewall—not just configured policies, but built reference architectures, guardrails, etc.

• Design & Architecture
  • Lead the end-to-end architecture of AWS Network Firewall across multi-account, multi-VPC topologies (Transit Gateway/Hub-Spoke).
  • Define policy management models, rule groups, stateless/stateful rule sets, inspection points, and logging strategies.
  • Integrate with AWS WAF and existing Palo Alto controls (e.g., mapping control coverage, defining policy precedence, and traffic steering).
• Implementation & Enablement
  • Stand up AWS Network Firewall infrastructure‑as‑code (Cloud Formation/Terraform), rule group pipelines, and environment baselines.
  • Build traffic inspection patterns (east-west, north-south, egress filtering, TLS decryption strategy where applicable).
  • Establish centralized logging to Cloud Watch, Kinesis, S3, and SIEM with alerting and metrics (threat detections, rule hit counts, packet drops).
• Security & Risk
  • Partner with security architecture, app teams, and networking to align on zero trust, segmentation, and least privilege egress.
  • Develop playbooks for detection/response (malicious egress, DNS tunneling, C2 callbacks).
  • Provide knowledge transfer and training to broaden internal bench strength.
