Senior Software Engineer I Java Platform Safer Changes Team

The Challenge: Engineering for Scale

At our scale testing isnt about manual checks or writing scripts; its a massive distributed systems problem. The Safer Changes team within Developer Enablement is responsible for building the internal platforms that allow 1000 engineers to ship code with maximum confidence and zero friction.

Note: This is a Backend Engineering role not a QA or SDET position. You wont be writing test cases for features. You will be architecting the Java-based infrastructure intelligence layers and orchestration engines that power the entire Wise engineering organisation.

What will you be working on

You will be solving problems at scale with large engineering-wide organisational impact. When you create platforms services and opinionated standards/best practices you help accelerate Wise Engineers to solving problems for our customers even faster. Specific challenges include:

• Distributed Test Orchestration: Architecting a high-throughput framework that automates the execution analysis and collation of results across thousands of concurrent jobs. Youll build the systems so that product engineers never have to think about how their code is validatedit just happens.

• Predictive Impact Intelligence: Building the logic and services that understand our microservice graph. Your code will determine exactly which business flows are impacted by a specific change automatically designing test scenarios and provisioning purpose-built ephemeral environments on the fly.

• Production-Grade Isolation: Developing the tooling and infrastructure that allows unmerged dirty code to be tested in pre-production environments safely ensuring engineers can experiment without impacting the stability of the testing platform or other developers.

How we work

We believe in automation as a product. We use Java and Spring Boot to build robust scalable internal services. We operate with a Platform-as-a-Product mindsetour customers are our fellow engineers and our bar for reliability security and performance is incredibly high.

What do you need

• Advanced Java Engineering: You are a seasoned backend engineer with deep expertise in Java and the Spring ecosystem (Spring Boot).

• Systems Thinking: You enjoy thinking about problems at scalehow services interact how data flows through a mesh and how to build fault-tolerant systems.

• Cloud Infrastructure: Experience with AWS or GCP and a solid understanding of how cloud resources (Kubernetes Docker) are provisioned and managed.

• A Product Mindset for Tools: You are passionate about developer experience. You want to build the tools you wish you had earlier in your career.

Nice to Have

• Experience with CI/CD Orchestration (e.g. GitHub Actions Spinnaker).

• Familiarity with SRE principles Chaos Engineering or observability stacks (Prometheus Grafana ELK).

• Knowledge of Service Mesh (Istio/Envoy) and complex cloud networking.

• A background in building internal developer platforms or high-leverage infrastructure.

You get back:

• True Autonomy: The freedom to define the technical vision for how Wise handles change safety.

• High Visibility: Your work is used by every engineer in the company every single day.

• Impact: Help us in our Mission towards Money Without Borders by ensuring our systems are the most reliable in the industry.

• Growth: A clear engineering career map that rewards technical depth and leadership.
