About Us

At CI&T, our rapid growth is fueled by the innovative solutions we create for our global clients. We are seeking a Master DataOps Engineer to own the operational backbone — environments, CI/CD, and monitoring — for a large-scale Finance data platform modernization at a major US mortgage lender, so the platform being built is reliable and cost-governed from day one, not bolted on at the end.

Responsibilities

Environment Provisioning & Platform Readiness

Own end-to-end environment provisioning and platform readiness across the full data stack — from SQL Server CDC source through Snowflake landing, raw, and curated layers — ahead of and during the build, with a formal readiness checklist delivered before sensitive-data build begins.

Provision and maintain Snowflake environments (DEV → QA → UAT → Prod) with dedicated, right-sized warehouses per workload class — replication/ingestion, curated-layer transformation, and BI serving — each with auto-suspend, resource monitors, and cost attribution from day one.

Coordinate Azure infrastructure provisioning: Virtual Networks, NSGs, Private Endpoints, Azure Key Vault, self-hosted Azure DevOps agents, and VM infrastructure for the CDC replication tool — including firewall rules, TLS certificate requests, and DNS resolution for private Snowflake endpoints, all with documented lead times surfaced proactively.

Manage Snowflake RBAC provisioning: dedicated project-specific role hierarchy, clearly separated from broad IT, developer, analyst, and AI roles; positive and negative access tests executed before the environment is handed over to the build team.

Manage the full vendor and service account access lifecycle: named, individual, time-bound, least-privilege access for all delivery personnel; dedicated non-personal service accounts for replication, Snowflake, and BI integrations; credential storage and rotation via Azure Key Vault; revocation with documented evidence at engagement end.

CI/CD Pipeline Engineering

Build and operate the CI/CD pipeline for all data artifacts — transformation logic, metric definitions, replication configurations, Snowflake object DDL, and versioned SQL transformation models — using Azure DevOps Pipelines with YAML-based, version-controlled pipeline definitions.

Enforce a DEV → QA → UAT → Prod promotion path with branch policies, required reviewers, build validation on PRs, and written approval gates before any production deployment — no silent or automatic production changes.

Integrate automated regression, schema validation, row-count checks, and data quality assertions at every promotion stage — not only before go-live.

Externalize all environment-specific configuration from code; integrate Azure DevOps Variable Groups linked to Azure Key Vault so no credentials are stored as plaintext in pipeline definitions or repository files.

Integrate code scanning, dependency scanning, and IaC scanning (e.g., Checkov, Microsoft Defender for DevOps) into CI pipelines; remediate or formally document exceptions for all material findings before promotion to production.

Design, document, and rehearse rollback procedures for every promotion stage, including a full mock cutover and rollback rehearsal before the production readiness gate.

Monitoring, Alerting & Observability

Implement and own end-to-end pipeline monitoring using Azure Monitor and Log Analytics: replication health, CDC lag alerts, replication agent availability, Snowflake warehouse freshness against agreed SLA targets, schema-change and drift detection events at the landing zone, and semantic-definition change alerts.
