Job description

We are looking for an experienced and detail-oriented Senior QA Tester to join in Helsinki. This is an exciting opportunity for a quality assurance professional with extensive mobile game testing experience to contribute to the ongoing development, improvement, and live operation of a high-profile mobile gaming title.

The ideal candidate will bring at least five years of hands‑on mobile QA testing experience, alongside a strong understanding of the challenges associated with maintaining quality across a live‑service mobile game. You will play a key role in ensuring that new features, gameplay updates, content releases, and live operations activities meet the highest standards of quality before reaching players.

We are particularly interested in candidates who have experience leading QA activities, coordinating testing efforts, and supporting quality assurance processes within a large‑scale mobile game environment. Experience working on a high‑traffic, live‑ops title would be highly advantageous, as the role requires an appreciation of the importance of stability, performance, and a seamless player experience in a continuously evolving game.

Working closely with developers, designers, producers, and other QA professionals, you will help identify potential issues early, improve testing processes, and ensure that every release delivers a polished and reliable experience.

Key Responsibilities

Quality Assurance & Testing

• Plan, execute, and maintain comprehensive test coverage across mobile game features, updates, and releases.
• Perform hands‑on functional, regression, exploratory, and integration testing across supported mobile platforms and devices.
• Identify, investigate, document, and track bugs, providing clear and actionable information to development teams.
• Validate new gameplay features, user interface updates, events, balance changes, and other game content.
• Verify bug fixes and ensure that previously resolved issues do not reappear in subsequent builds.
• Assess the overall stability, usability, and quality of game builds throughout the development and release cycle.
• Help ensure that new functionality integrates reliably with existing game systems and player‑facing features.

Live Operations & Release Quality

• Support QA activities for a live‑service mobile title, ensuring that regular updates and content releases meet established quality standards.
• Test live events, limited‑time content, seasonal updates, and other time‑sensitive game features.
• Help identify risks associated with frequent releases, balancing thorough testing with the demands of an active live‑ops schedule.
• Investigate issues that could affect player progression, gameplay functionality, in‑game economies, or the overall player experience.
• Contribute to release readiness assessments, highlighting outstanding defects, potential risks, and areas requiring further investigation.
• Collaborate with relevant teams to support smooth updates and minimise the risk of player‑facing issues following release.
• Take ownership of testing activities for assigned features, releases, or projects, ensuring that testing objectives and deadlines are met.
• Where appropriate, coordinate QA priorities and testing efforts across team members and development disciplines.
• Work closely with developers, designers, producers, and other stakeholders to communicate quality risks and establish effective testing strategies.
• Provide guidance and support to other QA team members, sharing knowledge and encouraging consistent testing practices.
• Help improve QA workflows, documentation, test planning, and defect management processes.
• Champion a proactive approach to quality, ensuring potential issues are identified and addressed as early as possible.
• Identify opportunities to improve testing efficiency, coverage, and overall QA effectiveness.
• Contribute to the development and maintenance of test plans, test cases, and quality assurance documentation.
• Analyse recurring defects and testing challenges to help prevent similar issues in future releases.
• Promote clear communication between QA and development teams to support faster issue resolution.
• Stay informed about mobile testing practices, platform‑specific considerations, and evolving approaches to game quality assurance.

To be successful in this role, you will ideally demonstrate the following:

• 5+ years of hands‑on mobile QA testing experience, preferably within the mobile games industry.
• Strong experience testing mobile games across iOS and Android platforms.
• A thorough understanding of functional testing, regression testing, exploratory testing, and defect reporting.
• Experience working on a live‑service or live‑operations mobile game, with an understanding of frequent updates and ongoing content releases.
• The ability to investigate complex issues, identify potential root causes, and communicate findings clearly to development teams.
• Strong attention to detail and a methodical approach to testing.
• Excellent organisational skills, with the ability to manage competing priorities in a fast‑paced development environment.
• Confidence working collaboratively with cross‑functional teams, including engineering, design, production, and QA.
• A proactive mindset, with a strong sense of ownership and accountability for product quality.
• The ability to work effectively in an office‑based environment in Helsinki.
