• Track and manage privileged access, database credentials, and system accounts securely
• Participate in architecture reviews and help drive infrastructure optimization efforts
• Coordinate with software developers, security teams, and stakeholders to ensure system reliability and compliance

Required Technical Skills & Experience

• 3–5+ years of specific experience supporting cloud‑hosted web applications and infrastructure
• Strong Linux/Unix administration experience with scripting (Shell, Python, Bash)
• Demonstrated expertise in AWS core services (EC2, RDS, Lambda, S3, KMS, Cloud Formation)
• Experience troubleshooting Tomcat/Java‑based web applications
• Familiarity with Dev Sec Ops  principles, CI/CD pipelines, and infrastructure as code
• Proven track record of handling compliance documentation (e.g., ATO, POA&Ms, contingency planning)
• Experience with monitoring, vulnerability scanning, and proactive incident response
• Excellent written communication skills for documentation and stakeholder reporting

Desired Skills & Experience

• Experience migrating or modernizing legacy systems to the cloud (AWS, Azure, GCP)
• Proficiency in infrastructure‑as‑code tools (Terraform, Cloud Formation, Ansible)
• Familiarity with containerization (Docker) and orchestration
• Working knowledge of RDBMS platforms (Postgre
  
  SQL, MySQL, Oracle, Kafka)
• Prior experience supporting federal customers or FedRAMP‑compliant environments
• Understanding of security frameworks (NIST CSF, RMF) and incident handling

Ideal Candidate Attributes
