About the role
- Senior Full Stack Developer responsible for building the Internal Developer Portal for software delivery efficiency within the enterprise.
Responsibilities
- Design, build, and operate Spring Boot 3 microservices (Java 17/21) within a distributed architecture that includes event orchestration, event processing, notification, work-item tracking, file upload (AWS S3), and service discovery (Eureka).
- Own database schema evolution using Liquibase against PostgreSQL, and write performant JPA/Hibernate queries with Hypersistence Utils for advanced column types.
- Implement and extend our custom workflow/flow engine built on Spring Integration, including authoring reusable event tasks (Git, GitHub Enterprise, Jira, SSH, email) and worker services.
- Harden security across services using Spring Security, OAuth2 (client + resource server), JWT (jjwt), Azure AD SSO, and HashiCorp Vault for secrets management.
- Build and maintain the API Gateway (Spring Cloud Gateway WebMVC) that fronts all backend services.
- Produce clean, self-documenting APIs with Springdoc OpenAPI (Swagger UI) and HATEOAS where appropriate.
- Develop and ship features across a Turborepo monorepo containing multiple single-page applications using React 19, TypeScript, and Vite.
- Build rich, accessible UIs with Material UI, Material React Table and D3-based data visualizations.
- Manage client-side state with Zustand and TanStack React Query; consume both REST and GraphQL APIs (URQL).
- Write thorough unit tests with Vitest + Testing Library and end-to-end tests with Playwright; maintain high code coverage via V8 coverage reporting.
- Collaborate closely with product owners and fellow engineers in an agile environment with frequent release cadences.
- Mentor and guide junior developers, drive technical decisions, and contribute to architecture discussions for a platform that is actively scaling.
Requirements
- 8+ years of professional software development experience with a strong full stack track record.
- Deep hands-on expertise with Java 17+ and the Spring ecosystem (Spring Boot 3, Spring Security, Spring Data JPA, Spring Cloud).
- Production experience building modern React applications with TypeScript, including state management (Zustand, React Query, or equivalent) and component libraries (MUI or similar).
- Solid understanding of relational databases (PostgreSQL), schema migration tools (Liquibase or Flyway), and ORM frameworks (Hibernate/JPA).
- Experience with RESTful API design, OpenAPI/Swagger, and at least working knowledge of GraphQL.
- Proficiency with containerization (Docker), CI/CD pipelines (Jenkins, GitHub Actions, or similar), and Kubernetes or OpenShift deployments.
- Strong testing discipline — you write unit, integration, and E2E tests as a matter of course (JUnit 5, Vitest, Playwright, WireMock).
- Undergraduate degree in Computer Science or any equivalent combination of education and experience.
- Bilingualism is required for candidates located in Quebec.
