• Support technologies such as PostgreSQL, Redis, Neo4j, Amazon S3, and Elasticsearch.

• Modernize existing services and develop Infrastructure as Code (IaC).

• Deploy and troubleshoot cloud-hosted applications and supporting infrastructure.

• Integrate identity services using OpenID Connect (OIDC), authentication, authorization, and Zero Trust principles.

• Maintain technical documentation, software designs, and operational procedures.

Required Qualifications

• Experience analyzing database internals, network protocols, or low-level software behavior.

• Strong SQL, relational database, and graph database knowledge.

• Experience with cloud infrastructure, automation, and identity integration using OIDC.

• Knowledge of Zero Trust Architecture and enterprise security controls.

• Experience with Agile, DevOps, or DevSecOps methodologies.

• Agile Developer or Certified Scrum Developer certification.

• CompTIA Security+ or higher cybersecurity certification.

Preferred Qualifications

• Master's degree in a related technical discipline.

• Experience with PostgreSQL, Neo4j, and database engine internals.

• Terraform, Ansible, AWS GovCloud, Kubernetes, or Red Hat OpenShift.

• Experience with PingFederate, Keycloak, SailPoint, Okta, or similar identity platforms.

• Experience with PKI, cryptographic integrations, Hardware Security Modules, or PKCS #11.

• Familiarity with Trusted Data Format, Protocol Buffers, and modern cryptographic technologies.
