Introduction
WEX is a global leader in financial technology solutions, simplifying complex payment ecosystems across Fleet, Corporate Payments, and Benefits. We are transforming our platforms through Helix — a company-wide initiative to modernize technology, accelerate innovation, and deliver exceptional customer experiences.
We're looking for a Full Stack Software Engineer (Level 2) to contribute to this transformation by designing and building reliable, scalable, and modern services. You'll help evolve our legacy systems into API-first, modular, and event-driven architectures that enable faster delivery, smarter workflows, and the foundation for agentic, intelligent systems.
Scope of Role
As a Level 2 Engineer, You Will
- Build and maintain API and microservice-based solutions that align with Helix's modernization and agentic architecture goals.
- Collaborate with senior engineers to decompose monolithic systems into reusable, composable components.
- Participate in the full software development lifecycle — design, coding, testing, deployment, and monitoring.
- Contribute to data pipelines, event streaming, and workflow automation that support agentic behavior.
- Learn and apply Helix principles — quality-first, API-first, reusable by design, and data-driven.
- Work cross-functionally with product, QA, and DevOps to ensure solutions are secure, performant, and maintainable
What You'll Do
- Develop and test secure, maintainable APIs and backend services that power intelligent workflows.
- Support event-driven integrations and real-time data processing (Kafka, CDC, JSON).
- Implement features that enable automation and intelligent decision flows within agentic systems.
- Participate actively in agile ceremonies, delivering incremental value with measurable outcomes.
- Contribute to CI/CD pipelines, observability, and automation frameworks.
- Write clear, reusable code and documentation to support discovery and reuse across teams.
- Collaborate with senior engineers to ensure technical solutions align with long-term Helix architecture
Required Qualifications
- Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent experience).
- 2–3 years of professional software development experience.
- Experience building or consuming REST APIs.
- Hands-on experience with Python, Java, or Node.js.
- Familiarity with event streaming platforms (Kafka preferred).
- Understanding of databases (SQL/NoSQL) and data exchange formats (JSON, XML).
- Experience with Git and basic CI/CD workflows.
- Solid understanding of how systems interact through APIs and services.
- Strong problem-solving and communication skills.
Nice to Have
- Exposure to microservices or modernization projects.
- Experience in FinTech or payment systems.
- Familiarity with cloud environments (AWS preferred) and containerization (Docker, Kubernetes).
- Exposure to Siebel CRM or other enterprise applications.
- Some experience with front-end frameworks (React, Angular, or Vue).
- Interest in AI and automation — especially in how intelligent agents can optimize workflows.
What Makes You a Great Fit
- You're eager to learn from senior engineers and contribute to building the future Helix architecture.
- You think about reusability, data flow, and automation when building solutions.
- You're curious about agentic systems and how technology can enable intelligent automation.
- You take pride in writing quality code that moves systems closer to cloud-ready, modular design.
- You thrive in a collaborative, fast-paced environment where modernization is a shared mission.
