Airlines have spent decades selling one trip at a time. At Caravelo, we help them build recurring relationships with their customers instead. We build the technology behind airline subscription products used by carriers around the world, combining SaaS, payments, booking systems and airline integrations in one platform. Our Product & Platform teams build the common technology. Our Professional Services team makes it work in the real world for each airline . Before those changes reach a customer, someone needs to make sure they actually work. That is where this internship comes in. As a Technical QA Intern in our Professional Services team , you will help us validate customer-facing changes before they reach production. You will test changes in sandbox, understand what they are supposed to do, investigate when something behaves unexpectedly and give the team a clear answer: ready to ship, or not yet, and why . You will also help us keep control of releases and validate production after deployment. This is a hands-on technical internship. You will work with APIs, databases, logs, frontend flows and payment transactions. You will read code when it helps you understand a problem and use AI to explore unfamiliar systems, investigate issues and build small tools or scripts that make your work faster. This is not a software engineering internship , but you will work very close to software engineering. The goal is not to teach you how to follow a testing checklist. The goal is for you to develop a genuine understanding of how a B2B SaaS product works end to end , how software reaches enterprise customers, and how to investigate when reality does not match expectations. You will report to the Director of Professional Services and work closely with Engineering, Product and our customer-facing teams. Test changes before they ship Validate functional and visual changes in sandbox as they move into testing. Understand what each change is supposed to achieve and verify that it behaves correctly. Clearly document failures so another person can reproduce and investigate them. Run end-to-end checks to make sure complete customer journeys continue working after changes. Help us release with confidence Keep visibility over what is included in each release and whether it has been validated. Help make sure untested changes do not accidentally reach customers. After deployment, perform exploratory checks in production to confirm the real environment behaves as expected. Investigate, not just report Use logs and monitoring tools to understand errors and unusual behaviour. Inspect backend data when it helps explain what happened. Work with APIs to reproduce and isolate problems. Learn how payment gateways, subscriptions and customer transactions flow through the system. Follow an issue far enough to understand why it happened, not only that it happened. Improve how we work Identify repetitive or error-prone tasks in your daily work. Use AI and lightweight automation to make testing and investigation faster. Build small scripts, helpers or internal tools when useful. Contribute ideas for making our testing and release process more reliable over time.
