Job Description

We are looking for a Java Full-Stack Engineer to design, build, and support modern web applications. This role spans front-end development (Angular or React) and back-end services (Java/Spring Boot), with a focus on API-first, microservices-based architecture and CI/CD-driven delivery.

Job Responsibility

  • Develop and maintain web applications across the stack: UI, APIs, and backend services
  • Build scalable, secure microservices using Java and Spring Boot
  • Develop responsive user interfaces using Angular, leveraging Kendo UI components where appropriate
  • Implement and support micro front-end patterns (composition, shared libraries, module federation or equivalent approaches)
  • Design, build, document, and consume RESTful APIs
  • ensure service contracts and versioning strategies are followed
  • Work with SQL Server and optimize queries, indexes, and data access patterns
  • Implement search and indexing solutions with Elasticsearch
  • Build event-driven integrations using Kafka (producers/consumers, topics, schema/versioning awareness)
  • Use GitHub / Bitbucket and contribute to automated CI/CD pipelines (build, test, deploy)
  • Write unit and integration tests
  • participate in code reviews and engineering best-practice adoption

Requirements

  • 6-10 years of experience in full-stack web application development
  • Strong backend development experience with Java and Spring Boot (REST APIs, security concepts, performance, and scalability)
  • Strong front-end development experience with Angular including TypeScript, HTML5, and CSS
  • Experience using UI component libraries such as Kendo UI
  • Working knowledge of micro front-end architecture and patterns
  • Solid understanding of API design and microservices (service boundaries, resilience, observability basics)
  • Hands-on experience with SQL Server and relational data modeling
  • Experience with Elasticsearch and event streaming with Kafka
  • Proficiency with GitHub / Bitbucket workflows and practical experience with CI/CD pipelines
  • Strong communication skills, ownership mindset, and ability to work collaboratively in an agile team
  • Bachelor’s degree in Computer Science, Software Engineering, or a related field (or equivalent practical experience)

Nice to have

  • Experience with cloud platforms (AWS, Azure, or GCP)
  • Containerization and orchestration experience (Docker, Kubernetes/OpenShift)
  • Experience with automated testing frameworks (unit, integration, and UI testing)
  • Exposure to observability practices (logging, metrics, tracing) and production support

What we offer

  • medical
  • dental & vision coverage
  • 401(k)
  • life, accident, and disability insurance
  • wellness programs
  • paid time off packages including planned time off (vacation)
  • unplanned time off (sick leave)
