Do you want to build awesome, engaging mobile games and scale them to millions of users?

Senior QA Engineer

  • Full time
Apply for this job

adjoe builds the technologies behind mobile apps growth and monetization. adjoe Ads is our programmatic in-app advertising platform that seamlessly connects advertisers and publishers through direct integration of our Android and iOS SDKs. Every ad decision happens in under 200ms across 10 million daily users, powered by real-time bidding algorithms and user quality prediction models that match the right ad to the right user at the right moment.

Where 50 Billion Daily Predictions Begin

The User Experience team is the origin point of adjoe Ads. Everything the system knows about a user, every prediction the ML models make, every bid placed in an auction. It all starts with code this team ships.

The team owns two responsibilities. On the SDK side, a native Kotlin and Swift code runs inside hundreds of publisher apps. It participates in 120 million daily auctions, renders ad creatives across multiple formats, and captures the behavioral signals that power 50 billion predictions per day. The constraint that defines this work: you’re executing inside someone else’s app, on someone else’s device, with zero tolerance for instability. Every ad impression has to feel native and fast to the user.

On the analytics side, the dashboards, investigation tools, and data frameworks that turn raw data into decisions: real-time revenue performance across active campaigns, infrastructure cost visibility, and data quality assessments. If a number matters to the business or to engineering, this team makes it accessible.

Your Mission & Who We Are Looking For:

  • You have 3+ years in QA with hands-on mobile testing experience. You test more than UI flows, you dig into the full stack, from SDK behavior on device to the backend systems behind it, using tools like Kreya and k9s to investigate services, and Kibana and Grafana to monitor system health. You’re comfortable working with AWS services and understand how container orchestration (Kubernetes, Docker), databases, and messaging systems (Kafka, SQS) behave under real conditions.

  • You own testing end-to-end. You develop and execute comprehensive test strategies: regression, smoke, and beyond, and take ownership of post-release and post-implementation validation. You don’t just report bugs, you understand the system well enough to know why they happen.

  • You work closely with engineers, not just alongside them. You investigate how systems work, participate in feature requirement discussions, and contribute product-related insights based on your testing findings. You’re comfortable reading and writing technical documentation.

  • Automation is part of your toolkit. You have experience building and maintaining automated test suites (Appium, Playwright) alongside manual testing responsibilities.

🌎 We welcome applications from talent worldwide and provide relocation support to Hamburg, Germany for those ready to join our team.

What’s in It for You?

At adjoe, you’re not here to just close JIRA tickets, you’re helping build the infrastructure behind one of the most impactful platforms in adtech. The systems you work on will reach hundreds of millions of users and power billions of decisions every day.

  • Go Big. Own projects with impact on 770M users and push adtech boundaries.

  • Move Fast. Ship solutions multiple times a day, learn from results, and keep momentum.

  • Be Direct. Solve problems openly and collaborate across teams.

  • Thrive Together. Grow with a diverse, global team of people from over 40 different countries that learn from each other.

  • Have Fun. Celebrate wins, enjoy daily victories, and bring your energy.

We welcome applications from people who will contribute to the diversity of our company.

Tips & Tricks to Nail Your Interviews!

mail

Skip cover letters

Since we want to keep everything fast and easy for you, we don’t want you to waste time on a cover letter – we would rather take a look at your CV and if it’s a match, we directly invite you to a first call.
done_all

Check your equipment

Test your internet connection, camera, mic, and speakers beforehand. Time for each interview is limited, and we’d like to spend as much of it as possible on getting to know each other. If the interview is online, always have your camera on! It’s way easier to create a meaningful interaction if we also see each other.
manage_search

Do some research

We will give you all the information about the role & company’s culture, but it’s always nice to see how you perceive us after doing some online detective work. 😉
elevator

Prepare an elevator pitch

We will certainly ask you to briefly summarize your work experiences in a short overview. Think of what you’re going to say beforehand so you can fit all of the essential information in 2-3 minutes. Keep the goal of the interview in mind, and make sure everything you say is relevant to the position you’re applying for.
fact_check

Structure your answers

Be specific, but don’t get caught up in details – following the STAR method can help you: Situation (set the scene and give the necessary details of your example) – Task (describe what your responsibility was in that situation) – Action (explain exactly what steps you took to address it) – Result (share what outcomes your actions achieved).
person_celebrate

Let your personality shine

It is a recruiting process, but this doesn’t mean you can’t loosen up and showcase your personality. We are looking for an authentic character and we are open to having some small talk or a funny joke thrown into the mix. This might even show us that you’re a good cultural fit. Remember, next to all our ambition we like to have fun!
live_help

Come with your questions

At the end of the interview, we will ask you whether you have any questions for us. Use this time to get answers to all your questions or clear out any curiosities. Always have two or three questions prepared, whether about the position specifically or about career development, upcoming projects, or company culture.

Don’t be afraid of rescheduling

Even if you’ve already scheduled an interview, urgent things might pop up in your schedule or you might not feel fit to attend the interview. We are all humans & we treat these situations with empathy. It’s better to reschedule rather than not be 100% prepared to attend the interview. Simply communicate the change with your TA Manager and we will find a solution.

Can I apply for multiple companies within applike group?

How do I know I’m really being contacted by someone from applike group?

We’ll never ask you for money, fees, or sensitive information (like bank details, tax forms, or credit card numbers) during the hiring process.
If anything feels off, you can always double-check by reaching out to our Talent Acquisition team at ta@applike-group.com.
Once you’ve signed your contract, our HR team may request personal details, but only from our official email: hr@applike-group.com.

Do I need to be located in Germany to be able to apply for your jobs?

No, we do provide full visa and relocation support. 

Do you help with my relocation?

We do! You can find more information about our relocation support and the succesful relocation of our colleagues here on this website.

What if I want to relocate together with my family?

No problem! Our visa and relocation support does also include your partner or kids. (Please be aware that legal marriage is often times a requirement to obtain a partner-visa).

Can I work remotely?

If you prefer 100% remote companies, applike is not the right place for you because we strongly believe in face-to-face collaboration. However, we did implement a hybrid working model where we are in the office at least three days a week (Monday, Tuesday, and Thursday) and can work remotely the remaining two days. Additionally, you get three whole weeks per year to work fully remotely if you want.

What does hybrid working and flexible working hours mean?

Our hybrid working approach involves being in the office at least three days a week (Monday, Tuesday, and Thursday) and the option to work remotely the remaining two days. Flexible working hours mean that we work Monday-Friday, but do not have fixed working hours. Just make sure to adapt to the rhythm of your team.

Where is your main-office located?

The headquarters of the applike group and all its subsidiaries are located in Hamburg, Germany. We do have offices in the US and APAC.

What is so great about your office?

Well next to the fact that you are able to see and collaborate with your colleagues face-to-face, we have a super modern office that leave no wishes open: from Drinks & Snack, areas to work away from your desk to a fully equiped gym.

Can I really bring my dog to the office?

Yes, you can!

Couldn’t find the perfect job offer?

Nevermind! We are always interested to get in touch with new talents.
