The Role
Build and maintain a cloud-native, multi-tenant SaaS platform using Java, Spring Boot, Angular, and TypeScript. Own features end to end across APIs, persistence, frontend rendering, testing, and deployment. Apply configuration-driven and plugin-based architecture patterns, design secure APIs, ensure tenant data isolation, and contribute to code reviews. Work with Hibernate, Oracle or relational databases, Docker, Kubernetes, CI/CD pipelines, and event-driven processing while modernizing a JBoss monolith into Spring Boot microservices.

Who are we?

At Finastra, we’re a global leader in financial services software, dedicated to expanding access to financial services and shaping what’s next for the industry. Our technology powers mission‑critical solutions across Lending, Payments and Universal Banking, supporting over 7,000 customers, including 80% of the world’s top 50 banks, in more than 110 countries.

About the Role

You will work on a cloud-native SaaS platform serving financial institutions globally, built on a modern Java + Angular stack. The team is modernising a large-scale enterprise system from a JBoss monolith to a multi-tenant Spring Boot microservices architecture, with a strong emphasis on configuration-driven extensibility over code generation.

Core Technical Requirements

Backend — Java / Spring Boot

  • 3+ years building production REST APIs with Spring Boot
  • Strong understanding of layered architecture — controller, service, domain, persistence
  • Hibernate ORM — entity mapping, relationship management, query optimisation
  • Oracle or equivalent relational database — schema design, SQL, indexing
  • Experience with event-driven or pipeline-based processing (validation chains, pre/post-save hooks, deserialisation pipelines)
  • Unit and integration testing with JUnit 5, Mockito, Spring Test

Frontend — Angular / TypeScript

  • Angular reactive forms, component architecture, HTTP client
  • TypeScript — interfaces, generics, strict mode
  • Schema-driven / configuration-driven UI rendering
  • Experience integrating with REST APIs and handling async state

Platform & Infrastructure

  • Docker — containerisation, multi-stage builds
  • Kubernetes — deployments, ConfigMaps, Secrets, volume mounts
  • CI/CD pipelines — build, test, deploy automation
  • Git — branching strategy, code review practice

Architecture & Design

  • Understands multi-tenant SaaS patterns — per-tenant data isolation, JWT-based tenant resolution, path-scoped configuration
  • Comfortable with configuration-over-code design — building systems where runtime behaviour is driven by YAML/JSON config rather than compiled logic
  • Familiar with extension/plugin architectures — hook registration, dynamic dispatch, runtime resolution of behaviour
  • Can reason about API contract design — what crosses a service boundary, what must be a plain DTO vs a domain object, versioning
What We Look For at This Level
  • You can own a feature end-to-end: backend API → persistence → frontend rendering — without requiring architecture sign-off on every step
  • You recognise when a configuration-driven approach saves a code change per customer, and you build for that
  • You write tests that cover the contract, not just the happy path
  • You flag security and data-isolation risks during design, not after deployment
  • You contribute to code review and leave the codebase cleaner than you found it

We are proud to offer a range of incentives to our employees worldwide. These benefits are available to everyone, regardless of grade, and reflect the values we stand for:

Flexibility: Enjoy unlimited vacation, subject to local regulations and business priorities. Benefit from hybrid working arrangements and inclusive policies such as paid time off for voting, bereavement, and sick leave.

Well‑being: Access confidential one‑to‑one support through our Employee Assistance Program, connect with our network of Wellbeing Champions and Gather Groups, and take part in monthly events and initiatives designed to help you thrive—inside and outside of work.

Health & Financial Security: Medical, life and disability insurance, retirement plans, lifestyle, and other benefits.*

Sustainability: Paid time off for volunteering and donation‑matching opportunities to support causes that matter to you.

Inclusion: Get involved in our inclusion communities, such as Count Me In, Culture@Finastra, Proud@Finastra, Disabilities@Finastra, and Women@Finastra—open to everyone who wants to participate and contribute.

Career Development: Access online learning and accredited courses through our Skills & Career Navigator tool.

Recognition: Take part in our global recognition program, Finastra Celebrates, and share your voice through regular employee surveys that help shape our culture and ways of working.

*Specific benefits may vary by location.

At Finastra, each individual is unique—bringing their own ideas, perspectives, cultural backgrounds, and experiences. We learn from one another, value what makes us different, and create an environment where everyone feels included, supported, and able to be their authentic selves.

Be unique. Be exceptional. Help us make a difference at Finastra.
