Who you are

- This is a first job, and we're hiring for it as such. We don't expect professional experience — we expect curiosity, care and enough technical grounding to get going

- Enough programming grounding to follow a codebase with AI as your guide: you won't be writing code, but you should be able to ask Claude what a piece of Java or Vue does, understand the answer, and tell when it doesn't add up

- Comfortable with Postman and working with APIs

- Familiarity with test automation tools such as Playwright and Selenium

- SQL and database knowledge; Couchbase or other NoSQL experience is a plus

- Familiarity with Git, enough to find your way around branches, commits and diffs when investigating an issue

- Able to write things down clearly, so that someone else can follow your notes and reproduce what you found
- A strong grasp of AI tools and, more importantly, good judgement about when and how to apply them
- The instinct to dig into why something broke rather than just reporting that it did

- English at a professional working level

- You've automated something repetitive with a script before, for a job, for a class or just for yourself

- You find payments, billing or subscription products interesting — you don't need to have worked on them

- You've come across CI/CD pipelines and roughly know what they're for

What the job involves

- Everything we build for our clients passes through Professional Services before it reaches production

- This role sits at that gate

- You'll join the Professional Services team, reporting to the Director of Professional Services





- You will be the person who tests every change in sandbox before it gets merged, and gives the verdict on it — either it's clean and ready to go, or it isn't and here is exactly what's wrong

- You'll also keep control of what each release contains, and on release day check that production behaves as expected once the deployment is live

- It's a hands-on technical role: you'll read code, query the database, poke at APIs, chase errors through logs, and build your own tooling to make the work faster
- The point of the internship isn't to run through a checklist someone else wrote

- It's to end up genuinely understanding how the product works end to end — which is one of the most useful things you can learn early in a career in tech

- You'll get full visibility of how a B2B SaaS product gets built, tested and shipped to enterprise clients, with real responsibility from early on — you're the quality gate before anything reaches a client

- Expect direct mentoring from the Director of Professional Services and close work with engineering, product and the client-facing teams,



plus freedom to explore how AI can make your own work faster and space to try out ideas for improving how the team operates

- Testing and quality:
- Pick up every ticket the moment it moves to In testing and test it in sandbox: functional and visual changes alike, verifying that they work as intended while building a solid understanding of the underlying product flows

- Give the verdict on each ticket — whether it's clean and ready to be merged to master, or, when it isn't, a precise and reproducible description of what fails

- Run end-to-end tests across the product to confirm that complete user journeys still work correctly

- Releases:
- Keep control of what each release contains and make sure everything in it has passed testing, so nothing untested slips out

- On release day, run exploratory testing in production once the deployment is live, to confirm the real environment behaves as the sandbox did

- Investigation and support:
- Monitor logs to catch errors early, and investigate root causes when one slips through

- Review backend data directly in the database

- Understand how our payment gateways operate and track transactions through the system

- Tooling:
- Use AI to build your own tools (eg for testing, for registration flows, for whatever slows you down) so your daily work gets faster over time
