Senior Test Engineer

Senior Test Engineer – Portfolios Team (Hybrid, Dublin Office)

We are looking for a Senior Test Engineer to join the Portfolios team in our Dublin office. This is a hybrid role, with an expectation of 50% in-office presence each week.

You will be part of a cross-functional team developing high-performance, data-driven platforms. This role offers the opportunity to contribute at every stage of the development lifecycle—from early system design through to post-deployment testing and performance analysis.

🌍 Who We Are

At Creditsafe, our mission is to power confident business decisions. We provide insights on more than 430 million companies globally, helping organisations identify risk and opportunity.

Founded in Oslo in 1997, we’ve grown to 23 offices worldwide. From SMEs to multinational enterprises, our customers trust us to deliver connected data through accessible, intuitive solutions powered by AI, machine learning, and automation.

🧭 About the Role

As a Senior Test Engineer, you’ll work across testing, architecture, and automation to ensure the quality of high-throughput data pipelines and APIs.

This role goes beyond traditional testing—you’ll be involved from the earliest phases of development, shaping product testability, visibility, and reliability from the ground up.

🛠️ Key Responsibilities

• Proactive QA: Contribute to architecture and design discussions to ensure systems are testable and scalable from the outset.

• API Testing: Develop automated tests for low-latency, high-availability APIs.

• Data Quality: Validate the integrity and freshness of data across platforms such as S3, Aurora, Postgres, and DynamoDB.

• Pipeline Testing: Design and execute tests for large-scale, high-volume data pipelines—ensuring consistent, accurate output from ingestion to delivery.

• Test Automation: Expand automation frameworks using tools like PyTest and Azure DevOps, embedding tests into CI/CD pipelines.

• Collaboration: Work closely with engineers, analysts, and product stakeholders to understand data flows and requirements.

• Troubleshooting: Identify and report issues clearly, and collaborate on resolutions.

• Performance Testing: Evaluate the performance of APIs and data flows, identifying areas for optimisation.

• Mentorship: Support and mentor team members, sharing knowledge and best practices.

(Please note this is not an exhaustive list of responsibilities.)

🧠 Skills & Experience

We recognise experience takes many forms—whether through formal roles, freelance work, or self-directed learning. You’ll ideally bring:

• Experience testing complex systems in data-heavy environments.

• Proficiency in Python for test scripting and automation.

• Familiarity with AWS services—especially S3, DynamoDB, Aurora, and API Gateway.

• Experience building or maintaining automated test frameworks.

• Knowledge of CI/CD pipelines and test integration (e.g. using Azure DevOps).

• Strong problem-solving and communication skills.

• A collaborative approach to continuous improvement.

• Previous experience mentoring others or leading testing initiatives (desirable but not essential).
