[Hiring] Software Engineering Intern @WEX

Role Description

We are seeking an inquisitive, proactive, and analytical Software Engineering Intern to join our Enterprise Applications & Systems Engineering organization. In this role, you will participate in solving a critical enterprise challenge: establishing a customer repository within our core enterprise architecture and CRM (Salesforce) by unifying data funneled through our modern data warehouse (Snowflake).

This internship offers hands-on enterprise systems experience, active mentorship from senior engineering leaders, and direct exposure to modern cloud data stacks and CRM architectures.

How you’ll make an impact:

• Investigate Source Systems: Trace data lineage across disparate systems (billing platforms, transactional processors, legacy portals, and operational services) to identify where key customer, account, and relationship attributes truly originate.
• Define Customer Schema: Partner with product managers, business analysts, and functional leads across Sales, Service, and Operations to document requirements for what constitutes the "single source of truth" for customer identity in Salesforce.
• Data Quality & Validation: Perform exploratory data analysis to evaluate consistency, detect schema drift, address duplicate records, and define mapping rules between upstream source models and their destinations.
• Build for Reusability: Assist in designing and building scalable, modular data extraction, transformation, and ingestion workflows so future source integrations can plug in with minimal custom code.
• Harness Snowflake: Write optimized SQL transformations, views, and data processing routines within Snowflake to clean, normalize, and stage customer datasets for downstream consumption.
• Integrate with Salesforce: Collaborate with Senior Salesforce Developers and Enterprise Architects to map staged Snowflake data into standard and custom Salesforce objects.
• Active Mentorship & Agile Sprints: Participate in daily stand-ups, backlog grooming, and architectural design reviews alongside senior systems engineers.
• Testing & Documentation: Document data dictionaries, entity-relationship diagrams (ERDs), integration flows, and automated validation tests to ensure maintainability.
• AI & Automation Exploration: Leverage AI-assisted developer workflows and modern automation tooling to accelerate querying, schema mapping, and documentation generation.

Qualifications

• Pursuing a Master’s degree in Computer Science, Machine Learning, Software Engineering, or a related field.
• A natural curiosity and tenacity for digging beneath the surface of complex systems to figure out how data flows, where discrepancies lie, and which source represents the ground truth.
• An instinct to build tools, scripts, and data models that solve problems systematically rather than with one-off manual patches.
• Solid academic or project experience writing structured SQL queries (joins, aggregations, window functions) and understanding relational database principles (foreign keys, indexing, entity relationships).
• Working knowledge of at least one programming or scripting language (e.g., Python, Java) and standard version control workflows (Git/GitHub).
• While prior hands-on experience with Snowflake or Salesforce is a plus, a demonstrable aptitude and enthusiasm to learn both enterprise platforms quickly is paramount.
• Ability to translate complex data structures into plain language when interviewing stakeholders and gathering requirements.

Requirements

• Participate in solving a critical enterprise challenge.
• Collaborate with senior enterprise architects, software engineers, and business leaders.
• Act as both a technical detective and a systems builder.

Benefits

• Health, dental, and vision insurances.
• Retirement savings plan.
• Paid time off.
• Health savings account.
• Flexible spending accounts.
• Life insurance.
• Disability insurance.
• Tuition reimbursement.
• Comprehensive and market competitive benefits designed to support personal and professional well-being.

Pay Range

$30.00 - $45.00
