• Troubleshoot functional and production issues and improve application performance, resilience, scalability, and maintainability.
• Collaborate with Product, UX, QA, DevOps, Architecture, and other engineers through design sessions, code reviews, planning, and continuous improvement.

Qualifications

• 6+ years of full-stack software development experience, including ownership of production applications.
• Strong hands-on experience with Java and Spring technologies, particularly Spring Boot, REST services, persistence, security, and automated testing.
• Solid frontend development experience with Angular or React, TypeScript, HTML, CSS, component-based design, state management, and modern testing practices.
• Familiarity with Node.js for lightweight services, integrations, build tooling, or supporting components.
• Proven experience designing REST APIs, microservices, and maintainable applications in distributed environments.
• Strong SQL skills and experience designing efficient data models in PostgreSQL or comparable relational databases.
• Experience developing, deploying, or supporting cloud-based and containerized applications.
• Excellent communication skills, including the ability to produce clear technical documentation and lead client-facing workshops.
• Knowledge of OAuth2, OpenID Connect, JWT, and secure API design.
• Experience with Kafka, RabbitMQ, or comparable messaging and event-streaming technologies.
• Familiarity with Kubernetes, cloud platforms, observability tooling, and secure software delivery practices.

Nice to have:

• Experience developing Workforce Management (WFM) applications or integrating with WFM platforms.
• Experience with AWS services and Amazon Connect
