About the role
We're looking for a Senior Full Stack Developer to join our high-performing team building our Internal Developer Portal that accelerates software delivery across the enterprise. This is a fast-paced, high-impact role where you'll own features end-to-end — from React frontends to Spring Boot microservices — and ship code that developers depend on daily.
What you'll do here:
Backend (Spring Boot / Java)
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 Postgre
SQL, 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, Git Hub Enterprise, Jira, SSH, email) and worker services.
Harden security across services using Spring Security, OAuth2 (client + resource server), JWT (jjwt), Azure AD SSO, and Hashi Corp 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.
Frontend (React / TypeScript)
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 Tan Stack React Query; consume both REST and Graph
QL 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.
Contribute to a shared component library and design system documented in Storybook; enforce code quality with ESLint, Prettier, Knip (dead-code detection), Husky, and lint-staged.
Cross-Cutting
Champion code quality through peer code reviews, Checkstyle, Spotless formatting, Sonar Qube analysis, and Ja Co Co coverage gates.
Ship containerized services via Docker multi-stage builds, Helm charts, and Jenkins CI/CD pipelines targeting Open Shift (ROSA), with integrated Nexus IQ, Twistlock, and Polaris security scanning.
Write comprehensive JUnit 5 unit tests, Spring Boot integration tests, and Wire Mock-based service tests on the backend; maintain Playwright E2E suites on both Java and JavaScript sides.
Collaborate closely with product owners and fellow engineers in an agile environment with frequent release cadences.
Mentor and guide junior developers, drive…
