The WEX Summer Internship Program: Learn, Lead, and Make an Impact

Our 13-week paid internship program, running from late May to mid-August, is a chance for you to gain real-world experience and develop your skills. Recruiting begins in September and continues through December at our various locations across the U.S.

You won't just be a bystander; you'll work on impactful projects and contribute to WEX’s mission. We provide mentorship, professional development, and weekly learning experiences to help you build confidence and leadership skills. High-performing interns may even get the chance to lead their own initiatives.

We offer remote, hybrid, and onsite options for flexibility, and our goal is to bring top interns back full-time or offer them extended roles during the school year. Imagine starting your career with a company that’s building what's next. Your future starts here.

About the Role: As a Software Engineer Intern, you will work alongside engineers and Product Managers to solve real-world business challenges. You will gain hands-on experience building scalable applications, learning modern engineering practices, and developing AI-driven features within modern cloud architecture.

How you'll make an impact:

  • Ship Full-Stack Features: Build user interfaces with React and backend services using C# / .NET, including basic database interactions and API development.
  • Build AI Solutions: Prototype and deploy AI agents or LLM integrations to automate workflows and enhance product capabilities.
  • Understand System Design: Gain hands-on exposure to high-level architecture principles, learning how microservices, APIs, and data flows connect across cloud systems.
  • Learn & Collaborate: Apply TDD/BDD practices, work through the full software lifecycle, and receive mentorship from senior engineers on high-availability systems.

Experience you'll bring:

  • Educational Foundation: Currently pursuing a Bachelor's degree in Computer Science, Machine Learning, Software Engineering, or a related field, having completed at least your Sophomore year prior to the start of the internship.
  • Hands-on academic or project experience with React, C# / .NET, and SQL/NoSQL databases.
  • Foundational understanding of high-level software architecture, microservices, or RESTful system design concepts.
  • Familiarity or interest in AI agent frameworks (e.g., LangChain, Semantic Kernel) and LLM concepts.
  • Strong problem-solving skills, adaptability, and eagerness to learn during a fast-paced internship.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
