Full Stack Engineer

Position: Full Stack Java Developer

Location: Toronto, ON (2-3 days Hybrid)

Contract: Long term

We are looking for a Full Stack Java Developer to build and enhance modern web applications using Angular on the frontend and Java/Jakarta EE on the backend. The role also requires working knowledge of databases and practical familiarity with AI-assisted development tools and LLM application components (e.g., vector databases and orchestration frameworks). You will collaborate with product, QA, and DevOps teams to deliver secure, testable, container-ready solutions.

• Develop and maintain SPA features using Angular 17+, TypeScript 5.x, and Angular Material / Material Design.

• Build backend services using Java 17+ and Jakarta EE 10 (REST APIs, validation, security, integration patterns).

• Design and implement API contracts, error handling, logging, and performance-conscious services.

• Write and maintain automated tests:

Frontend: Jest

Backend: JUnit 5

• Work with databases: create/modify schemas, write queries, tune basic performance, and support migrations.

• Apply AI tools and patterns to improve productivity and/or product features:

• Use AI coding assistants (e.g., GitHub Copilot, Windsurf/Devin) effectively and responsibly.

• Integrate or support LLM-based capabilities using vector databases (e.g., ChromaDB or similar) and orchestration frameworks (Lang Chain or Haystack).

• Use Git for version control and participate in code reviews and branching workflows.

• Build and package applications using Maven containerize and run services with Docker.

• Collaborate in agile ceremonies, contribute to estimations, and communicate progress and risks clearly.

• Troubleshoot issues across the stack (UI, API, database, container/runtime) and contribute to root-cause analysis.

• Develop and maintain SPA features using Angular 17+, TypeScript 5.x, and Angular Material / Material Design.

• Build backend services using Java 17+ and Jakarta EE 10 (REST APIs, validation, security, integration patterns).

• Design and implement API contracts, error handling, logging, and performance-conscious services.

Professional experience delivering full stack applications with:

• Angular 17+, TypeScript 5.x, Angular Material

• Java 17+, Jakarta EE 10

• Testing experience with Jest (frontend) and JUnit 5 (backend).

• Working knowledge of databases (relational preferred): SQL querying, joins, indexes basics, transactions, and data modeling fundamentals.

AI enablement experience/knowledge:

• Handson familiarity with GitHub Copilot and/or windsurf/Devin

• Understanding of vector databases (e.g., Chroma DB or similar) and typical RAG flows

• Exposure to Lang Chain or Haystack concepts (chains/pipelines, retrieval, prompt management)

• Strong fundamentals in HTTP/REST, JSON, authentication/authorization basics, and secure coding practices.

• Proficiency with Git, Maven, and Docker in day-to-day development.
