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.
