What will you be doing

As a Senior Java Fullstack Engineer, you will play a key role in designing and building high-performance, scalable visualization platforms such as Plasma Studio and Office add-ins. You will focus on delivering modern, interactive, and robust analytics experiences that enable users to seamlessly explore and interact with data from our Analytic Server.

You'll collaborate closely with lead engineers to design reliable components, debug complex issues, and ensure the system performs efficiently under load.

Job Responsibilities:

• Full-Stack Development: Design, develop, and maintain secure, scalable, and high-performance applications using Java (backend) and Angular (frontend), owning features end-to-end from design to production.
• Backend Engineering: Architect and implement robust, scalable RESTful APIs and data pipelines using the Java Spring Boot ecosystem, ensuring reliability, performance, and observability.
• Frontend Engineering: Develop responsive, modular, and accessible user interfaces using Angular (TypeScript), ensuring cross-browser compatibility and optimal performance with semantic HTML5 and advanced CSS/SASS.
• AI Integration: Design and integrate AI-powered features, leveraging Large Language Models (LLMs), vector databases, and frameworks such as LangChain, enabling intelligent and context-aware user workflows.
• Database Management: Design and optimize complex data models and queries for both relational (PostgreSQL, MySQL) and NoSQL databases, focusing on performance, scalability, and data integrity.
• CI/CD: Own and enhance automated CI/CD pipelines, ensuring reliable, secure, and efficient software delivery across environments.
• Code Quality & Collaboration: Write clean, maintainable, and well-tested code, participate in code reviews, architectural design discussions, and technical documentation, while driving engineering best practices.

Requirements:

• 4–8 years of hands-on experience in full-stack development
• Backend: 4+ years of professional experience in Java (Java 11 or higher) and the Spring Boot framework. Strong grasp of concurrency, multithreading, and microservices architecture
• Frontend: 2+ years of hands-on experience with Angular (v20+ preferred), RxJS, state management, and component-driven architecture
• Web Fundamentals: Expert knowledge of HTML5, CSS3, SASS/LESS, and responsive web design frameworks
• AI Experience: Practical knowledge of AI integrations, including interaction with AI APIs (OpenAI, Anthropic), working with vector embeddings, RAG pipelines, or deploying/running local SLMs
• Databases: Deep knowledge of SQL (PostgreSQL, Oracle) and experience with NoSQL and vector databases (e.g., MongoDB, ChromaDB, Pinecone)
• Testing: Experience with testing frameworks such as JUnit, Mockito, Jasmine, Karma, or Cypress
• Strong understanding of data structures and algorithms
• Solid knowledge of multithreading and concurrency
• Understanding of threads, synchronization, locks, and thread-safety concepts
• Knowledge of TCP/IP fundamentals, sockets, and client-server architecture
