About The Role

Loghic Hire is seeking a Senior Data Engineer with deep, hands-on expertise in Azure Databricks and AWS to design, build, and operate modern cloud data platforms for our enterprise clients. You will own the end-to-end data lifecycle — from ingestion and transformation to serving and governance — and act as a technical anchor for data engineering across the organization.

This is a build-and-lead role. You will write production-grade PySpark / SQL / Python code, architect medallion (bronze/silver/gold) pipelines, tune Databricks clusters and Delta Lake workloads, and integrate AWS-native services where they add value. You will also mentor engineers, define standards, and partner with analytics, data science, and platform teams.

You will work in a hybrid model based in Lisbon, collaborating on-site with the team and client stakeholders while retaining flexibility for remote work.

Key Responsibilities

• Data Platform Architecture & Design


• Design and deliver cloud-native data platforms on Azure Databricks and AWS, covering ingestion, storage, processing, serving, and governance layers.


• Architect medallion architectures (Bronze / Silver / Gold) using Delta Lake with ACID transactions, time travel, and schema evolution.


• Define lakehouse vs. warehouse boundaries and integrate with Azure Synapse, Snowflake, Redshift, or Athena as appropriate.


• Design batch, micro-batch, and streaming pipelines using Spark Structured Streaming, Kafka, Event Hubs, or Kinesis.


• Establish data modeling standards — dimensional, Data Vault, and wide-table patterns — fit for analytics and ML consumption.


• Produce architecture decision records (ADRs), design documents, and reference architectures.


• Evaluate and recommend build-vs-buy decisions across the Azure and AWS data ecosystems.


• Data Ingestion & Integration


• Build scalable ingestion frameworks from relational databases, SaaS APIs, event streams, files, and third-party sources.


• Implement CDC (Change Data Capture) patterns using Debezium, Azure Data Factory, AWS DMS, or Databricks Lakeflow Connect.


• Orchestrate pipelines with Apache Airflow, Azure Data Factory, Databricks Workflows, or AWS Step Functions.


• Integrate on-premises and hybrid sources into cloud data platforms securely and reliably.


• Own idempotency, replayability, and backfill strategies for all ingestion paths.


• Implement data contracts between producers and consumers to prevent upstream breakage.


• Transformation & Processing


• Write production-grade PySpark, Spark SQL, and Python for large-scale transformations.


• Optimize Databricks jobs and clusters — partitioning, Z-ordering, liquid clustering, photon, autoscaling, and job clusters vs. all-purpose clusters.


• Tune Spark performance: shuffle, skew handling, broadcast joins, caching, and AQE.


• Build reusable transformation frameworks and libraries that enforce standards across teams.


• Implement Delta Live Tables (DLT) / Lakeflow Declarative Pipelines for declarative, testable pipelines.


• Apply data quality checks using Great Expectations, Soda, or DLT expectations, with quarantine and alerting paths.


• Manage schema evolution, versioning, and backward compatibility rigorously.


• AWS & Azure Cloud Engineering


• Provision and manage data infrastructure with Terraform (and/or Bicep / CloudFormation) as code.


• Work hands-on with AWS services: S3, Glue, Athena, Redshift, Kinesis, Firehose, Lambda, Step Functions, EMR, IAM, KMS.


• Work hands-on with Azure services: Data Lake Storage Gen2, Azure Data Factory, Synapse, Event Hubs, Key Vault, Entra ID, Databricks workspace administration.


• Design cost-efficient storage and compute strategies — lifecycle policies, tiering, spot/preemptible instances, and cluster policies.


• Implement networking and security for data platforms: private endpoints, VNet/VPC injection, NSGs/security groups, and firewalls.


• Own IAM / RBAC / Unity Catalog access models across both clouds.


• Data Governance, Security & Compliance


• Implement Unity Catalog for fine-grained access control, lineage, and auditing on Databricks.


• Integrate with AWS Lake Formation and Azure Purview / Microsoft Purview for cataloging and lineage.


• Enforce data classification, masking, tokenization, and encryption at rest and in transit.


• Ensure compliance with GDPR and other applicable regulations, including right-to-erasure and data residency.


• Establish audit logging, monitoring, and alerting for sensitive data access.


• Partner with security and compliance teams on control evidence and audits.


• Reliability, Observability & Operations


• Define SLAs / SLOs for data freshness, completeness, and availability.


• Instrument pipelines with metrics, logs, and traces (OpenTelemetry, CloudWatch, Azure Monitor, Datadog, Grafana).


• Build data observability using tools like Monte Carlo, Elementary, or custom frameworks.


• Lead root-cause analysis for pipeline failures and drive permanent fixes.


• Implement CI/CD for data pipelines — Git-based workflows, automated testing, and environment promotion.


• Own disaster recovery and business continuity for critical data assets.


• Participate in an on-call / escalation rotation for production data platforms.


• Technical Leadership & Collaboration


• Mentor and coach data engineers — code reviews, design reviews, and pairing.


• Set and enforce coding, testing, and documentation standards.


• Partner with data scientists, analysts, and product teams to translate requirements into robust pipelines.


• Represent Loghic Hire in client architecture and delivery reviews.


• Contribute to internal accelerators, templates, and best-practice playbooks.


• Help interview, onboard, and grow the data engineering practice.
