Software Development Engineer 2

Introduction WEX is a global leader in financial technology solutions, simplifying complex payment ecosystems across Fleet, Corporate Payments, and Health & Benefits. For further details, do visit www.wexinc.com . We are driving a major technology transformation to modernize our platforms, accelerate innovation, and deliver exceptional customer experiences.

We are seeking a mid level Software Engineer (SDE-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 organization’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 organization’s engineering 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 the organization's long-term architecture goals.

Required Qualifications Bachelor’s/Master’s degree in Computer Science and Engineering.

3+ years in backend/micro-services development leveraging Java tech stack.

Experience building and consuming REST APIs.

Hands-on experience with Java and Java related frameworks.

Expertise in object oriented design and programming.

Strong problem solving skills in the software engineering domain.

Experience in working on modern backend micro-services architecture.

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 communication and collaboration skills across distributed teams.

Nice to Have Exposure to microservices or modernization projects.

Experience with FinTech solutions or payments ecosystems.

Experience with large-scale transactions and highly available systems.

Familiarity with cloud environments (AWS preferred) and containerization (Docker, Kubernetes).

Familiarity with modern UI frameworks (React, Angular, Vue.js).

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 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.
