About The Position

We are looking for a Senior Full Stack Engineer to design, build, test, and maintain reliable full-stack applications. You will use Java and Spring Boot to develop scalable backend services, Angular or React with TypeScript to create responsive user experiences, and Node.js where appropriate for supporting components. The role suits a hands-on engineer with strong software development fundamentals who can take features from technical design through implementation, testing, deployment, and production support. Experience with Workforce Management (WFM), Customer Experience (CX), or contact center solutions is an advantage.

Requirements

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.

Nice To Haves

Experience developing Workforce Management (WFM) applications or integrating with WFM platforms.
Experience with AWS services and Amazon Connect.
Experience building applications for CX solutions, contact centers, or customer service environments, including voice infrastructure or integrations using FreeSWITCH, Kamailio, Twilio, or comparable communications platforms.
Knowledge of forecasting, scheduling, adherence, routing, agent desktop, digital channels, or related operational concepts.
Experience with Kafka, RabbitMQ, or comparable messaging and event-streaming technologies.
Familiarity with Kubernetes, cloud platforms, observability tooling, and secure software delivery practices.
Experience integrating applications with CRM, identity, HR, payroll, analytics, or other enterprise systems.
Practical experience with AI-assisted software development or AI-enabled solutions, including tools such as Claude or GitHub Copilot, is a plus.

Responsibilities

Design, develop, test, and maintain scalable backend services using Java, Spring Boot, and established software engineering practices.
Build modern web applications using React, TypeScript, reusable components, responsive layouts, and accessible interaction patterns.
Develop and consume REST APIs using an API-first approach; maintain clear OpenAPI/Swagger contracts and error handling.
Design modular, maintainable solutions using microservices and appropriate object-oriented and domain-driven design patterns.
Use Node.js where appropriate for lightweight services, backend-for-frontend components, integrations, or development tooling.
Design and optimize PostgreSQL data models and queries with attention to integrity, performance, and audit history.
Design and implement reliable integrations with internal and external systems using REST APIs, webhooks, messaging, and other appropriate integration patterns.
Containerize applications and contribute to cloud-based deployment patterns, configuration management, and environment consistency.
Build and maintain Jenkins-based CI/CD pipelines with automated testing, quality gates, and repeatable deployments.
Instrument applications with structured logging, metrics, tracing, and actionable error reporting.
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.
