Branch Chief-Cloud Infrastructure Architecture, (BC-COT)

This position will provide senior technical leadership for the design, modernization, and governance of Auxiliary infrastructure. The Branch Chief sets the cloud and platform architecture vision; leads R&D across AWS, containerization, hypervisors, and Linux migration strategies; and converts that vision into secure, scalable reference designs, standards, and runbooks. The role establishes guardrails for cost, security, and reliability; oversees IAM patterns and access models; architects DNS with Route 53/Cloudflare; implements edge protections with AWS WAF; leverages serverless and EC2 compute; and partners with systems administration, database, and software engineering teams to deliver projects that move the Auxiliary forward: safely, efficiently, and cost-effectively.


The candidate will own the end-to-end infrastructure architecture roadmap and turn R&D outcomes into actionable designs, pilots, and repeatable patterns. Define cloud governance (tagging, account structure, guardrails, cost allocation), shape IAM strategies and least-privilege access, and drive EC2 right-sizing, CloudWatch observability, and cost optimization with clear reporting. Lead planning for Linux platform migrations and platform evolutions (containers, hypervisors, and serverless), design DNS architectures across Route 53 and Cloudflare, and apply AWS WAF policies to mitigate web threats. Coordinate change and cutover strategies, provide senior escalation on complex integration and reliability issues, mentor the BA-COTA, keep standards/SOPs/diagrams/runbooks current, and communicate changes through the chain of leadership and management.


The ideal candidate shall have an educational background and professional work experience in the public or private sector in activities related to the Division’s core functions including:

  • Auxiliarist in good standing; completes/maintains mandated training.
  • Advanced working knowledge of AWS architecture, including IAM, EC2 right-sizing, CloudWatch, Budgets/Cost Explorer, and cost optimization.
  • Strong working knowledge of AWS WAF, Amazon Route 53, Cloudflare DNS, serverless (e.g., Lambda/API Gateway), S3, RDS, and Amazon Aurora.
  • Deep background in infrastructure architecture and Linux platform design/migration strategies.
  • Practical experience with containerization and virtualized environments.
  • Proven ability to establish governance (tagging, guardrails, cost allocation) and write clear standards/runbooks.
  • Excellent cross-functional leadership and communication skills; able to translate R&D into production-ready patterns.

The following skills are NOT required but a plus:

  • Scripting/automation (Bash/Python/Terraform/CloudFormation) and Git-based workflows.
  • Cloud or Linux certifications (e.g., AWS Practitioner/Associate, Red Hat RHCSA/RHCE).
  • Familiarity with security services (CloudTrail/GuardDuty) and basic risk/threat modeling.

The candidate should be able to demonstrate experience and ability in setting goals, creating schedules, authoring excellent written products, and briefing results. They should be able to work both independently and in a volunteer team environment. This is a senior-level role with oversight over junior level role(s).
