Team Lead - Quality Assurance (f/m/x)

Festanstellung, Vollzeit · Hamburg

Your mission

This is a company built for growth.

At exmox, you’ll work on real systems on a big scale. We build high-performing consumer products used by millions of users, operating in a highly competitive, global mobile gaming ecosystem.

Our products are data-driven by design - powered by event-driven architectures, complex business logic, and fast feedback loops. Decisions are informed by data, experimentation, and measurable impact, not gut feeling.

We’re scaling fast and building one of the most exciting innovations in mobile gaming: rewarded user acquisition. That means distributed systems, evolving architectures, and problems that don’t have textbook answers.

As a QA Lead (f/m/x), you will guide the QA strategy, actively improve testing practices, and ensure product quality aligns with both technical and business goals.If you’re excited by complex systems, high traffic, data-driven decisions, and the chance to grow by solving challenging problems, we want to hear from you.

What You’ll Own

Team leadership & mentoring
You mentor and coach QA engineers, supporting their technical growth and professional development through regular 1:1s and structured performance reviews. You lead QA team meetings, coordinate testing efforts, and communicate quality status and risks to stakeholders, fostering a culture of quality ownership and continuous improvement.
Test strategy & execution
You lead the development and execution of test plans, test cases, and automated test scripts. You drive the implementation of automated testing within CI/CD pipelines and collaborate with development teams to provide early, proactive feedback on product quality and testability.
Defect management & root cause analysis
You identify, document, and manage software defects across multiple environments and platforms. You monitor test results, perform root cause analysis, and ensure issues are tracked and resolved efficiently, participating in code reviews to advocate for clean, reliable releases.
Process improvement & QA scaling
You continuously improve and scale QA methodologies, workflows, and documentation across teams. You partner with product and engineering leadership to align QA priorities with business goals and delivery timelines.

Your profile

Proven QA & leadership experience
You have 4 - 6 years of experience in software QA, including at least 2 years in a lead position, mentoring teams and driving QA strategy.
Automated testing & CI/CD expertise
Hands-on experience with automated testing frameworks such as Cypress, Selenium, or Playwright, and familiarity with CI/CD tools like GitHub Actions, Jenkins, or GitLab CI.
Agile collaboration & problem-solving
Experience working in Agile/Scrum teams, collaborating closely with cross-functional stakeholders. Strong problem-solving skills, attention to detail, and ownership mindset.
Communication & team development
You communicate clearly, proactively engage with developers and stakeholders, and support your team’s growth through coaching and mentorship.
Education & domain knowledge
Bachelor’s degree in Computer Science, Information Technology, or a related field.
Nice to have

Why us?

Ambitious people, real ownership. You’ll work with driven, entrepreneurial people who care deeply about what they deliver, challenge each other openly, and own outcomes together.
We’re playing at the top, but we’re not done. Our apps rank in the top 5 of their categories. We’re determined to push further, compete harder, and earn the number one spot.
You own your own growth. Growth doesn’t happen by accident. At exmox, learning is built into the work - through responsibility, feedback, and real challenges.
Perks that help you focus on what matters. Transport subsidy, learning budget, wellness and gym, workation, bi-weekly team lunches, and more. The perks are great - but the real reason people join and stay is the challenge, the people, and the drive to win together.

Please note: this is not a remote only position, we offer you a flexible hybrid model here in Hamburg, Germany - working from home on Mondays & Fridays, coming to the office on Tuesday, Wednesday & Thursday! :)
