The role

- Support D365 governance requirements.
Performance & Capacity Management
- Monitor capacity usage, throttling and performance risks.
- Analyse performance of SQL, Spark, notebooks, Delta optimisation and semantic models.
- Implement optimisations such as query tuning, indexing, scheduling improvements and compute scaling.
Data Quality & Schema Management
- Detect schema changes, datatype shifts, anomalies and missing/late data.
- Maintain and run data quality rules (duplicates, thresholds, data completeness).
- Investigate and resolve data quality issues.
Change Delivery & Continuous Improvement
- Deliver customer‑requested changes through formal Change Management.
- Update pipelines, schemas, calculated fields, metadata and RLS roles.
- Optimise slow‑running workloads and provide impact/rollback assessments.
Connectivity, Security & Access
- Troubleshoot linked services, runtime failures and network access issues.
- Provide guidance on gateway configuration and authentication.
- Support cloud gateway remediation and manage workspace/dataset/lake permissions.
Tooling, Documentation & Knowledge Management
- Use telemetry, logs and diagnostics to investigate reliability and performance issues.
- Maintain data dictionaries, lineage documentation, runbooks and data flow diagrams.
- Ensure all changes are recorded in up‑to‑date support documentation.
What will I bring to the role?
Essential
- Experience supporting and operating production data platforms.
- Strong SQL skills, including optimisation and troubleshooting.
- Spark-based data processing and performance tuning experience.
- Hands‑on work with pipelines/orchestration, lakehouse/warehouse architectures, and semantic models.
- Familiarity with incident and change management processes.
- Strong problem‑solving and root‑cause analysis abilities.
- Clear, structured documentation skills.
Desirable
- Experience with Microsoft Fabric, Azure data services or similar cloud analytics platforms.
- DAX optimisation skills.
- Understanding of capacity‑based analytics and throttling behaviour.
- Experience in customer‑facing managed services.
- Knowledge of data governance, lineage and data quality frameworks.
Behaviours & Attributes
- Customer‑focused with a strong service mindset.
- Confident in high‑availability production environments.
- Calm, methodical incident diagnosis.
