Description
About the team / Role
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 Senior Software Engineer (SDE-3) 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.
How you'll make an impact
As a Level 3 Engineer, you will:
Lead design and development of full-stack solutions, with emphasis on event-driven micro-services, APIs, and data platforms.
Drive iterative modernization, helping decompose monoliths into shared, modular services.
Build reusable capabilities aligned with product-centric domain models.
Contribute to agentic architectures and intelligent automation that power seamless user experiences.
Collaborate with cross-functional teams to deliver measurable business outcomes, not just features.
Mentor junior developers and promote best engineering practices.
Experience you will bring
Design, develop, test, and maintain cloud-ready micro-services and APIs.
Work with streaming data pipelines (Kafka, CDC) to enable real-time insights.
Implement platform-thinking approaches—build reusable, discoverable capabilities.
Ensure quality from the start through automated validation and CI/CD pipelines.
Deliver value iteratively, focusing on finishing and deploying features, not just starting them.
Partner with product and architecture teams to ensure systems are decoupled, scalable, and SaaS mature.
Use monitoring and feedback loops to drive data-informed improvements.
Tackle technical debt proactively, balancing modernization with customer value delivery.
Required Qualifications
Bachelor’s/Master’s degree in Computer Science and Engineering.
5+ years in backend/micro-services development leveraging Java tech stack.
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.
5+ years in building Restful APIs, exposing and consuming; experience with message broker and event streaming (Kafka).
Strong knowledge of SQL, relational and non relational databases.
Comfortable working with JSON, XML, YML and other interfacing file types.
Experience in Unix/Linux environments, scripting, and CI/CD pipelines.
Demonstrated ability to decompose systems into modular, reusable services.
Excellent communication and collaboration skills across distributed teams.
Nice to Have
Experience with FinTech solutions or payments ecosystems.
Cloud experience (AWS preferred), containerization (Docker, Kubernetes).
Experience with large-scale transactions and highly available systems.
Familiarity with modern UI frameworks (React, Angular, Vue.js).
Familiarity with Change Data Capture (CDC) tools.
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 staff 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.
