• Proficiency in Python and SQL for data processing, transformation, and scripting
• Demonstrated experience developing, integrating, or consuming RESTful APIs in a backend context
• Proven experience deploying infrastructure using Terraform in a team-based GitOps workflow
• Solid understanding of data lake architecture, data modeling principles, and pipeline orchestration (batch and streaming)
• Experience with monitoring and observability tooling (e.g., CloudWatch, Prometheus, Grafana), including alerting and dashboarding

Nice To Haves

• 1–3 years of professional experience in production-grade cloud, data, or backend engineering roles.
• Hands-on experience with orchestration platforms such as Apache Airflow, dbt, or AWS-native equivalents for automated pipeline management.
• Proficiency in containerization and backend service deployment workflows, including Docker and orchestration on ECS or EKS, with knowledge of CI/CD integration.
• Experience developing and maintaining backend applications using Python frameworks such as Django or FastAPI, or Node.js frameworks such as Express.js.
• Familiarity with microservices architecture and service-to-service communication using REST or gRPC.
• Understanding of event-driven architectures using AWS SNS, SQS, Kinesis, or Kafka.
• Experience with unit testing, integration testing, and continuous testing practices (e.g., PyTest, Jest).
• Knowledge of relational and NoSQL databases (e.g., PostgreSQL, DynamoDB, MongoDB) and ORM frameworks (e.g., Django ORM, SQLAlchemy).
• Experience deploying and integrating machine learning models into production systems using frameworks such as scikit-learn, TensorFlow, or PyTorch.
• Familiarity with MLOps workflows — model packaging, versioning (e.g., MLflow), and monitoring in a cloud environment.

Responsibilities

• Implement and maintain cloud infrastructure using infrastructure-as-code and CI/CD pipelines (Terraform, Git-based workflows)
• Develop, test, and monitor ETL/ELT data pipelines for ingestion, transformation, and analytics-ready data flows
• Maintain and scale Core’s cloud-native data lake to support business reporting, data quality, and financial operations
• Build, manage, and operationalize backend APIs and service integrations, ensuring secure and stable data exchange
• Support internal applications and operational tooling deployments — focusing on automation, availability, and performance
• Implement observability tools (e.g., logging, tracing, monitoring, alerts) across infra and data systems
• Participate in incident resolution, root-cause analysis, and ongoing ops improvement
• Create and maintain technical documentation: pipeline architecture, API contracts, infrastructure diagrams, and data lineage
• Collaborate with internal teams to deliver consistent and auditable cloud solutions aligned to enterprise standards
