We are seeking a highly accomplished Senior Software Developer - ETL to lead the technical design, data ingestion strategy, and performance optimization of enterprise-scale data storage repositories. In this role, you will take technical ownership of translating complex system specifications into secure, high-performance data engineering workflows. Operating at the core intersection of distributed cloud computing and business intelligence, you will build automated data pipelines, implement robust governance controls, and optimize multi-tiered data architectures to ensure seamless data delivery for mission-critical applications.
...
Location: North York, ON
Duration: 9-month contract.
Advantages
Cutting-Edge Data Stack: Drive high-value technical initiatives leveraging premium, distributed big data frameworks and modern transformation suites.
End-to-End Core Ownership: Command complete functional autonomy over the data lifecycle—from raw cloud ingestion to performance-optimized reporting layers.
Enterprise-Scale Pipeline Impact: Shape large-scale, high-velocity data lakehouse environments supporting mission-critical digital workflows.
Elite Telemetry & Governance Exposure: Expand your engineering profile by establishing state-of-the-art cataloging frameworks and data lineage models.
Responsibilities
Data Lakehouse Architecture: Design, implement, and maintain highly scalable Medallion Data Lakehouse architectures (Bronze, Silver, and Gold tiers) to capture, store, and process massive enterprise datasets.
Pipeline Engineering & Automation: Build, automate, and tune complex ETL/ELT pipelines using data integration factories, orchestration workflows, and transformation tools to handle both structured and unstructured data streams.
Distributed Computing Optimization: Develop data-driven logic and streaming frameworks utilizing distributed clusters, optimizing query execution, data indexing, partitioning schemes, and storage file formats.
Database Modeling & Warehousing: Design logical and physical dimensional data models, integrating disparate data sources into optimized star and snowflake schemas ready for downstream analytics.
Incident Triage & Quality Assurance: Investigate and resolve data loading exceptions, performing deep root-cause analysis to distinguish between software failures and source-data quality anomalies.
Business Intelligence Integration: Build and connect high-performance data models with cloud data warehouses, implementing advanced calculations and performance tuning to support seamless user reporting.
Data Governance & Permissions Management: Operationalize advanced cataloging engines and data governance frameworks, managing fine-grained data permissions, data lineage tracking, and role-based access controls (RBAC).
CI/CD Lifecycle Operations: Implement automated deployment packages and release routines using continuous integration pipelines to manage the lifecycle of data platform infrastructure.
Technical Evaluation & Modeling: Conduct detailed technical design evaluations, option analyses, and gap assessments for complex integration components to resolve architectural blockers.
Documentation & Reference Design: Produce and maintain comprehensive technical specifications, logical system models, metadata dictionaries, and operational deployment guides to support long-term environment maintenance.
Qualifications
Core Data Engineering Seniority: 10+ years of progressive professional experience translating complex system specifications into tested, working applications for large-scale, mission-critical environments.
Cloud Lakehouse Expertise: 10+ years of verified hands-on experience designing and implementing Medallion Data Lakehouse architectures, utilizing tools such as Databricks (PySpark, SQL, Delta Live Tables), Delta Lake, and dbt.
Pipeline Orchestration Mastery: Demonstrated success constructing and automating enterprise ETL/ELT data pipelines using Azure Data Factory (ADF) and configuring job schedules.
Advanced Database Scripting & Modeling: Mastery of relational database management systems (SQL Server, Synapse, PostgreSQL) and dimensional modeling alongside advanced SQL query optimization and replication tuning.
Big Data Storage Mechanics: Practical development experience manipulating Apache Spark distributed environments and working with storage formats including Parquet, ORC, and JSON.
Cloud Infrastructure Depth: High proficiency navigating cloud ecosystems, specifically Azure Data Lake Storage (ADLS), Azure Synapse Analytics, Event Hubs, and Azure Functions.
Governance & Security Acumen: Direct, practical experience implementing enterprise data access controls, cloud security models, data lineage tracking, and Unity Catalog data governance.
Business Intelligence Interoperability: Strong experience integrating front-end systems like Power BI (DAX, performance tuning) with cloud warehouses and data pipelines.
CI/CD Delivery Skills: Proven background applying continuous integration and automated deployment protocols via Azure DevOps or GitHub Actions.
Technical Evaluation & Assessment: 5+ years of explicit experience running gap analyses, assessing technical options for architecture issues, and delivering robust system integration designs.
Soft Skills: Outstanding leadership, negotiation, and verbal/written communication skills, with an established history of managing multi-stakeholder expectations and resolving data roadblocks with diplomacy.
Nice to Have:
Prior software engineering experience delivering large-scale data solutions within a public sector or healthcare information management infrastructure.
Familiarity with machine learning tracking applications (e.g., MLflow, AutoML) to embed predictive insights directly into streaming data pipelines.
