Job description
We're hiring a Data Engineer to own the data layer across our product portfolio. This is a database-first role and a deliberately broad one: you'll write and optimize the T-SQL that our applications run on, design the schema new features are built against, and keep the pipelines that move data from ingestion through processing to reporting correct, fast, and auditable.
We're not hiring for a single project. You'll move between products and problem domains — real-time event ingestion, transactional processing, reporting and analytics, historical migrations — so we're looking for someone adaptable who gets productive in an unfamiliar schema quickly and is comfortable owning more than one system at a time.
You'll work across multiple database instances — development, staging, and production — and own the packaging and deployment path between them, so that what's checked into source control is provably what's running. Correctness is not negotiable: the queries you write decide what our applications return and what our reports say. You'll partner closely with the API and frontend engineers who consume your procedures, and you'll be the person who answers "why does this number look wrong?"
Tech Stack
Database: Azure SQL, T-SQL, stored procedures, table-valued parameters (TVPs), user-defined functions, temp-table staging patterns, query plan analysis
Packaging & Deployment: SQL Server Database Projects (.sqlproj / SSDT), SqlPackage and DACPAC publishing, schema compare and drift detection, versioned migration scripts, multi-instance (dev / staging / prod) deployment
Data Movement & Analytics: Azure Storage Queues, Azure Table Storage, Azure Blob Storage, Azure Functions, queue drainer services, bulk upsert/apply patterns, Microsoft Fabric (Lakehouse / Warehouse / Data Factory pipelines / Power BI semantic models), CSV/Excel export generation
Consuming Layers: ASP.NET Core (.NET 8) with Dapper, C# — enough to read and reason about how your procedures are called
Infrastructure: Azure (SQL Database, Storage, Key Vault, Application Insights), Azure DevOps Pipelines, sqlcmd / Azure Data Studio / SSMS, Entra ID authentication
Responsibilities
Design, write, and optimize T-SQL stored procedures for real-time ingestion, transactional processing, reporting, and application data access
Own the schema for large relational databases (100+ tables) — tables, indexes, constraints, TVPs, and migration scripts
Package and deploy database changes across multiple instances using SQL Database Projects and SqlPackage/DACPAC, and detect and resolve schema drift between environments
Verify data integrity as a first-class deliverable — enforce and validate keys, constraints, and referential integrity; write the checks that catch orphaned, duplicated, and contradictory rows before they reach production consumers
Build automated data-integrity and reconciliation checks that run continuously, not just when someone reports a problem
Diagnose and fix query performance problems: execution plans, missing indexes, correlated subqueries, unbounded scans, and timeouts at production volume
Build and maintain data pipelines that move high-volume event data from ingestion queues into processed, queryable, reportable records
Write reconciliation queries that prove downstream output ties back to source data — and investigate when it doesn't
Handle historical data migrations, backfills, and legacy-to-current data reconciliation
Keep paged and non-paged (export) variants of reporting procedures in lockstep so the on-screen grid and the exported file never disagree
Model and surface data in Microsoft Fabric for analytics and reporting workloads as we build that capability out
Partner with API engineers on contract changes — parameter shape, result sets, and DTO mapping
Contribute to CI/CD for database deployments and keep checked-in objects aligned with what's actually deployed
Pick up unfamiliar schemas and legacy data models across different products and get to a working understanding fast
Write reusable, well-documented SQL that the next engineer can safely change
Required Qualifications
3+ years professional experience in a database-focused engineering role (Data Engineer, Database Developer, or similar)
Strong T-SQL — stored procedures, CTEs, window functions, temp tables, TVPs, dynamic SQL where it's warranted
Demonstrable query optimization skills: reading execution plans, index design, and diagnosing slow queries at volume
Relational schema design — normalization, keys, constraints, soft-delete and status-flag patterns, slowly-changing/point-in-time data
Experience with SQL Server or Azure SQL in production
Hands-on data integrity work — constraint and referential-integrity design, duplicate and orphan detection, and writing validation queries that prove a dataset is sound
Experience working across multiple database environments and promoting schema changes between them
Experience with database packaging/deployment tooling — SqlPackage, DACPAC, SSDT, Flyway, Liquibase, or equivalent
Experience building or maintaining data pipelines / ETL processes
Comfortable working with large datasets and reasoning about correctness, not just output
Adaptable across products and domains — you've worked on more than one system and can context-switch without losing rigor
Version control discipline for database objects (Git, migration scripts, or database projects)
Able to read enough C# or another application language to understand how your data layer is consumed
Preferred Qualifications
Microsoft Fabric experience — Lakehouse, Warehouse, Data Factory pipelines, Dataflows Gen2, OneLake, or Power BI semantic models
SQL Server Database Projects (SSDT / .sqlproj) and SqlPackage/DACPAC publishing in a CI/CD pipeline
Azure SQL specifics — DTU/vCore tuning, Query Store, elastic pools, managed identity authentication
Azure Storage — Queues, Tables, and Blobs as part of a data pipeline
Experience in domains where output must reconcile exactly and a wrong number has real consequences
High-volume event or transactional data processing experience
Point-in-time / temporal data modeling (values and configuration that must be resolved as of a historical timestamp)
Azure Data Factory, SSIS, or equivalent orchestration tooling
Dapper or micro-ORM data access patterns
Azure DevOps (Pipelines, Boards, Repos)
Python or PowerShell for data tooling and one-off analysis
What We Value
Clear, direct communication — say what you mean, flag problems early, ask questions when something is unclear
Verifying against the real object — read the deployed procedure, run the query, check the plan; don't trust documentation or assumptions about what the data does, and don't assume one instance matches another
Fixing problems at the source instead of working around dirty data downstream
Challenging risky or incorrect decisions instead of silently going along
Treating data output as something that must be provably correct, with a query that demonstrates it
Curiosity across the whole portfolio — willingness to learn a new domain rather than staying in one comfortable corner
Pragmatism over over-engineering — solve the problem at hand without gold-plating
