QA Platform Engineer

Were Capital on Tap
Capital on Tap started because small businesses were underserved. Big banks were slow their products werent fit for purpose and small business owners often couldnt access what they needed. We set out to fix that.

Today were a financial platform - not just a credit card company. We offer a best-in-class business credit card SME-focused spend management platform a savings product that hit 1 billion in funds within its first year and a growing suite of tools and financial products that make running a small business easier.

1000 employees 20bn in annual card spend 200000 customers 17000 Trustpilot reviews averaging 4.7 stars and were profitable. Weve done a pretty good job so far but were just getting started!

We partner with Engineering Data Security and QA teams to build platforms that reduce toil and make engineers lives easier.

Were always exploring new tools testing ideas and applying industry best practices to keep our platform cutting-edge and our teams empowered.

What Youll Be Doing

• Develop a deep understanding of how infrastructure changes differ from application changes and become a subject matter expert in the unique challenges of testing them safely and effectively.
• Define and own the frameworks processes and guardrails that ensure infrastructure changes are validated consistently across all environments from development through to production.
• Build and maintain automated validation pipelines that verify infrastructure changes at each stage of promotion catching drift regressions and misconfigurations before they reach production.
• Establish clear standards for what good infrastructure testing looks like at Capital on Tap covering areas such as plan validation policy compliance integration testing and rollback verification.
• Design provision and maintain dedicated test environments on Azure ensuring they are stable reproducible and closely mirror production.
• Own the Infrastructure as Code (Terraform) for all test environment provisioning teardown and configuration management.
• Collaborate with QA and Product Engineering teams to understand environment requirements and translate them into reliable scalable infrastructure.
• Develop and enforce standards around test data management including data seeding masking and refresh strategies to support consistent and repeatable testing.
• Monitor the health and availability of test environments using existing observability tooling proactively identifying and resolving issues before they block teams.
• Contribute to incident management processes ensuring infrastructure-related failures are diagnosed quickly and learnings feed back into improved guardrails and processes.

Our Values & Culture

• Just Pilot: We never settle for good enough. We pilot new ideas fast ask questions to figure it out and scale quickly.

• Familiarity with policy-as-code compliance validation or infrastructure testing approaches (e.g. validating configurations detecting drift or verifying rollback behaviour).
• Solid understanding of containerisation and Kubernetes particularly in the context of running isolated ephemeral test workloads.
• Familiarity with CI/CD pipelines and how infrastructure change validation fits into automated delivery workflows.
• Comfortable working with observability and alerting tooling to monitor environment health and surface issues early.
