DESCRIPTION

Capitole is growing fast, and we want you to be part of the journey!

We are looking for a Senior Data Platform Engineer with +6 years of experience to help drive the evolution of our Azure-based Data Platform and Lakehouse architecture. This role is focused on the platform itself. The professional will own and evolve the foundations that data product teams build on: Apache Airflow orchestration (migrating from ADF), Azure resource management (Key Vault, identity and access, networking, storage), Azure DevOps CI/CD and Infrastructure as Code, Databricks and Unity Catalog governance, observability and cost efficiency, while remaining hands-on and close to the teams that use the platform.

Responsibilities:

Orchestration Platform (Apache Airflow & ADF)

- Own the Apache Airflow platform: environments, deployment, upgrades, configuration, connections, variables, pools and DAG standards.
- Work on the migration from Azure Data Factory to Airflow and the evolution of the Metadata-Driven Orchestration Framework (DAG generation, reusable operators, dependency and scheduling patterns).
- Ensure Airflow is reliable and observable: SLAs, alerting, retries, backfills, health monitoring and clear failure ownership.

Azure Resource Management

- Manage Azure resources with Infrastructure as Code (Terraform): Databricks workspaces, Data Lake Storage, Data Factory, Key Vault, networking and supporting services.
- Own secrets and identity management: Key Vault, service principals and managed identities, secret scopes and rotation.
- Own access management: Azure RBAC, Entra ID groups, Unity Catalog grants and ownership, following least privilege, plus access requests and periodic reviews.
- Own Azure DevOps: repositories, CI/CD pipelines, branch policies and multi-environment promotion, including deployment validation and Terraform state.
- Track cost and governance of Azure resources: tagging, budgets, right-sizing and cost attribution (e.g. query tagging).

Hands-on Data Platform evolution

- Contribute to the implementation of the Data Catalog and Data Quality Framework and it’s lineage across the platform.
- Drive observability: pipelines that are observable, debuggable and alert-driven, with clear ownership of failures.
- Operate the Databricks platform: Unity Catalog structure, cluster and job policies, Auto Loader ingestion patterns,



and performance and cost optimization of workloads.

Technical Leadership

- Participate in architecture reviews and technical decision-making, stating trade-offs (performance, cost, reliability, complexity) with data.
- Define and promote engineering standards: naming conventions, patterns and guidelines, through code reviews and design reviews.
- Collaborate with Architects, Product Owners and data engineers in technical maturation of data products.
- Build and maintain developer tooling and automation, including AI-assisted engineering workflows (shared agent instructions, skills, automated PR review).

Support & Operations (Run Team Collaboration)

- Provide second-line support to the Run/Operations team for complex production topics.
- Troubleshoot and resolve platform incidents, failures and performance issues; lead root cause analysis and post-mortems.
- Ensure proper handover, documentation and operational readiness of platform changes.
- Continuously improve runbooks, monitoring and operational processes.

Requirements:

Technical Skills

- 6+ years of experience in data engineering, with significant time on platform or infrastructure topics
- Strong technical expertise with Python and SQL (advanced), including PySpark and Delta Lake semantics
- Deep hands-on experience with Apache Airflow in production: DAG design, deployment, operations, upgrades, and orchestration of Databricks and ADF workloads
- Hands-on experience with Azure resource management:

o Key Vault, managed identities and service principals, secret management

o Access management: Azure RBAC, Entra ID, Unity Catalog permissions

o Azure DevOps (repos, pipelines, service connections, environments) and CI/CD for data platforms

o ADLS, networking and security basics, Azure Data Factory

- Infrastructure as Code (Terraform) and multi-environment promotion
- Hands-on experience with Databricks and Unity Catalog (compute, jobs, governance)
- Observability and monitoring,



alerting and incident management
- Solid understanding of Data Lakehouse architecture, Medallion architecture and metadata-driven architecture; awareness of cost management and performance

Soft Skills

- Strong problem-solving and analytical thinking
- Ability to work in cross-functional teams and to influence without authority
- Ownership mindset and attention to detail
- Good communication skills with both technical and business stakeholders: leads with the recommendation, quantifies, and is transparent about uncertainty

What we’re looking for in you:

-
Led an Airflow implementation or migration (ideally from ADF), or run it at scale.
- Built metadata-driven orchestration or reusable ETL frameworks.
- Built developer tooling or LLM-agent workflows (MCP, skills, automated review) for engineering teams.
