[Hiring] Principal Database Engineer @WEXWEXUS

Role Description

WEX is looking for a highly experienced Database Engineer to help modernize and scale critical data platforms while supporting the next generation of AI-enabled applications. This is a hands-on engineering role for someone who brings deep expertise in SQL Server and T-SQL, combined with the ability to solve complex database performance, scalability, and modernization challenges at enterprise scale.

You will work across large, business-critical data environments, partnering closely with application engineering, SRE, operations, and architecture teams. The role is highly technical and execution-oriented—you will be expected to independently identify problems, drive solutions, and take ownership from design through implementation and production.

The team is also applying modern AI capabilities to database engineering, including:

• AI-assisted development
• Automation
• Semantic search
• Embeddings
• Vector-based data infrastructure

Qualifications

• 15+ years of experience in database engineering, data platform engineering, software engineering, or a related technical discipline.
• Deep hands-on experience with Microsoft SQL Server and T-SQL, including complex stored procedures, query optimization, execution-plan analysis, indexing, and performance tuning.
• Demonstrated experience modernizing or refactoring legacy database systems, not simply maintaining existing environments.
• Experience working with large-scale, business-critical databases and high-volume data environments.
• Strong programming skills in Python, C#, or a similar language for automation, tooling, and data processing.
• Experience with data pipelines, ETL/ELT, data integration, batch processing, and/or event-driven architectures.
• Strong understanding of database internals, transaction management, concurrency, locking, and performance optimization.
• Experience working across engineering teams and independently driving complex technical initiatives.

Requirements

• Experience using AI coding assistants such as Cursor, GitHub Copilot, Claude Code, Augment, or similar tools.
• Familiarity with embeddings, vector databases, semantic search, or RAG concepts.
• Experience with or willingness to build AI-enabled data tooling and automation.
• Exposure to technologies such as PostgreSQL, Snowflake, Azure SQL, Cosmos DB, AWS data services, or similar platforms.
• Experience with infrastructure-as-code such as Terraform, ARM/Bicep, or similar technologies.
• Experience with CI/CD, source control, database migrations, schema versioning, and deployment automation.
• Experience with event streaming technologies such as Kafka is a plus.
• Familiarity with NoSQL and document databases is a plus.

Benefits

• Health, dental, and vision insurances
• Retirement savings plan
• Paid time off
• Health savings account
• Flexible spending accounts
• Life insurance
• Disability insurance
• Tuition reimbursement
• Quarterly or annual bonus based on role and applicable plan

Company Description

WEX operates at a significant enterprise scale, and our database platforms are foundational to critical customer and business experiences. This role sits at the intersection of deep database engineering, large-scale modernization, cloud data platforms, and emerging AI technologies.

You will have the opportunity to apply proven database engineering expertise to some of the industry's most challenging data problems while helping shape how AI can transform the way modern engineering teams build, operate, and evolve data platforms.

This is an opportunity for an engineer who wants to remain deeply technical while operating with the ownership and influence expected at the Senior Staff level.
