Role Overview

We are seeking a skilled (SECURITY CLEARED) Python Infrastructure Engineer to support and enhance the infrastructure for a Python-based data and application platform. The ideal candidate will have strong Python skills alongside deep experience in Infrastructure as Code (IaC), cloud security, and CI/CD practices. You will play a key role in maintaining and evolving the infrastructure underpinning critical applications and data pipelines.

Key Responsibilities

• Codebase Management & Maintenance: Maintain and enhance the existing digitall-land-python codebase, ensuring reliability, scalability, and compliance with coding standards. Collaborate with developers and data engineers to support application lifecycle and deployment workflows.
• Infrastructure as Code (IaC): Design and implement Terraform scripts to provision and manage cloud infrastructure (e.g., AWS, Azure, or GCP). Ensure infrastructure is modular, version-controlled, and reusable across environments.
• Infrastructure Security & Governance: Establish and enforce infrastructure security best practices, including secure networking, encryption, and logging. Work with security teams to conduct threat modeling, penetration testing, and audit logging.
• Identity and Access Management (IAM): Implement and manage IAM policies and permissions for cloud-native applications and GitHub repositories. Define least-privilege access roles for both human and service identities, aligning with compliance requirements. Oversee changes to environment variables and secrets for multiple applications and Airflow DAGs, ensuring secure storage and controlled access. Maintain configuration consistency across dev, test, staging, and production environments.
• Strong Python programming background with experience supporting infrastructure-heavy codebases.
• Proven experience with Terraform or similar IaC tools (e.g., Pulumi, AWS CloudFormation).
• Deep knowledge of cloud platforms (AWS, Azure, or GCP), with a focus on provisioning, security, and IAM.
• Familiarity with CI/CD tools (e.g., GitHub Actions, Jenkins, CircleCI) and Git-based workflows.
• Hands-on experience with Airflow, particularly DAG management and operational reliability.
• Solid understanding of DevOps, SRE, or platform engineering principles.
• Exposure to secrets management tools (e.g., AWS Secrets Manager, HashiCorp Vault).
• Experience managing GitHub organization permissions and automations via APIs or Terraform providers.
• Background in working with data engineering platforms or data lakes.
• Experience with containerization (Docker) and container orchestration (Kubernetes) is a plus.
