Skilled in planning, designing, and implementing enterprise-level security and/or network solutions within cloud environments

Develops secure and high-quality production code and reviews and debugs code written by others, with a focus on cloud network security automation and infrastructure-as-code

Minimizes security vulnerabilities by following industry insights and governmental regulations to continuously evolve security protocols, including creating processes to determine the effectiveness of current controls

Works with stakeholders and business leaders to understand secure connectivity requirements and recommend appropriate architectural patterns and modifications during periods of vulnerability or change

Experience with AWS services including serverless solutions, ECS, EC2, Lambdas, API Gateway, and networking services such as VPCs, Transit Gateway, and PrivateLink

Ability to review and validate AI-assisted code/security recommendations before adoption, escalating uncertainty and ensuring outcomes align to security, resiliency, and auditability expectations.

Good communication skills, teamwork capabilities, and a self-learning attitude

Demonstrated experience using enterprise-authorized AI capabilities within the work environment to support security engineering workflows with strong validation habits and awareness of data sensitivity.

Preferred Qualifications, Capabilities, and Skills

Experience with forward or reverse proxy technologies and architectures at enterprise scale (e.g., F5, Squid, Envoy, or equivalent)

Hands-on experience with TLS/SSL certificate management, PKI, mTLS, and truststore configuration in cloud-native environments

Strong understanding of proxy protocols (HTTP CONNECT, HTTPS, SOCKS5), DNS-based routing, and network egress control patterns

Experience effectively communicating with senior business leaders

AWS Certifications (e.g., Solutions Architect, Security Specialty, Advanced Networking Specialty)
