Looking for Senior Full-Stack Developer (Java/Spring Boot + Angular) more backend.

Location: Remote (EU time zone overlap preferred) Engagement: Full-time

About the Project

You’ll join a live, production B2B SaaS platform in the sales/revenue operations space - pipeline management, sales process configuration, risk alerting, and role-based analytics dashboards. The product is fully shipped and actively used, running on AWS with enterprise SSO (OAuth2/OIDC) and a data platform integration. This is not a greenfield build - it’s an established codebase with strong engineering discipline (test coverage gates, pre-commit hooks, CI enforcement) that you’ll extend and help harden further.

Tech Stack

Frontend

• Angular 19
• TypeScript
• RxJS + BehaviorSubject-based state management
• Tailwind CSS with a custom design-token system
• ngx-translate (multi-language, 3 locales)
• Dexie / IndexedDB for local/offline storage
• Karma/Jasmine unit tests (85% coverage gate), Playwright for E2E
• Docker -> AWS ECS Fargate
• Datadog RUM for real-user monitoring

Backend

• Java 17, Spring Boot
• PostgreSQL with Flyway migrations
• Spring Security, OAuth2/OIDC
• Integration sync with an external data platform (Databricks)
• JUnit5 + Testcontainers
• AWS Secrets Manager
• Docker -> AWS ECS Fargate

Responsibilities

• Build and maintain features end-to-end across Angular frontend and Spring Boot backend
• Work within (and help enforce) a hexagonal/DDD-oriented architecture - keep domain logic decoupled from framework and persistence concerns
• Raise automated test coverage in backend domain/application layers toward the team’s stated target, and help introduce architecture-conformance checks (e.g. ArchUnit) to lock in dependency boundaries
