• Full-cycle people management experience - hiring, developing, and managing a team, not just individual performance execution
• Experience managing large budgets at team level ($1M+/mo aggregate)
• Track record of scaling ad budgets multiple times over (e.g. 4-6x within 1-2 years)
• Ability to combine hands-on campaign work with strategic planning and people management - this is not a purely strategic, hands-off role
• Strong analytical skills: attribution, funnel analysis, cohort thinking, unit economics
• Experience building or owning automation/martech systems for acquisition, with genuine interest in AI-driven tooling and workflows.

Nice to have:

• Experience with subscription business models, ideally on an AI/SaaS product
• Personal experience launching an ad channel from zero, ideally on Google Ads

We offer:

• Real ownership of LTV and P&L for your acquisition function - not just a media budget to spend, but a business outcome to run
• Build an AI-first UA function and own the martech stack - automate the routine, spend your head on hypotheses and scale
• Work with large aggregate budgets and technically complex tasks in an international company
• Direct influence on company-level growth strategy, working side-by-side with the GM
• A team and function to build and scale - hire, shape, and grow it your way
• Fast decision-making and diverse projects with measurable impact
• Flexibility in approaches - no processes for the sake of processes
• Competitive compensation package + regular performance reviews
• Flexible schedule, option to work remotely or from the office
• Respect for work-life balance (vacation and sick days included)
• Corporate events, gifts, and additional medical insurance
• Compensation for professional training and conferences.

 🎯 Role Overview:

We're an iGaming product company building and operating white-label casino and betting platforms — web products, payment systems, and game integrations across dozens of brands;

Our QA function currently consists of 20+ manual QA engineers and a small automation team distributed across 7 product teams:

• Platform Core;
• Payments;
• Brand Setup;
• Operations;
• Games.

We're looking for a Head of QA to transform our quality assurance function from a reactive, manual-heavy process into a proactive, metrics-driven, automation-first practice;

This is a change-agent role, not a caretaker role. You'll own the QA strategy, rebuild processes, introduce and manage quality metrics, and drive the reduction of manual testing through automation and AI tooling;

You'll report to the CDO and work closely with PMs, development leads, and the Release Manager.
 

     👤 Our Criteria:

• 7+ years of experience in QA, including 3+ years leading QA teams of 10+ engineers across multiple product teams;
• Proven track record of transforming QA processes — you've moved at least one organization from reactive "firefighting" testing to proactive quality engineering through shift-left practices, risk-based testing, and quality gates in the delivery pipeline;
• Hands-on experience designing, implementing, and managing quality metrics: escaped defects, reopen rate, test coverage, time-in-QA, release timeliness — and using them to manage the team, not just report results;
• Strong experience building and scaling test automation: defining automation strategy, prioritizing automation based on ROI, growing AQA capacity, and integrating automated suites into CI/CD pipelines;
• Practical, demonstrable experience using AI tools in QA workflows — including test case generation, autonomous/agent-based testing, AI-assisted test maintenance, and LLM-based log and defect analysis. Not just "interested in" — but actual production usage with measurable results;
• Experience with QA estimation and capacity planning (estimates vs. actuals, workload balancing across teams);
• Strong understanding of testing web applications, APIs, and integrations; comfortable working with logs, API responses, and DB queries;
• Experience managing Jira/Confluence-based workflows, including standardizing workflows and statuses across teams;
• Strong people leadership skills: hiring, performance reviews, grading, growth plans, and retention of senior engineers.
  
  ⚙️ Your Tasks:
• Own and rebuild QA processes across all product teams: unified test strategy, entry/exit criteria, consistent workflows, defect lifecycle management (including acceptance quality measurement where it doesn't exist today), and documentation standards;
• Introduce and manage quality metrics: define the metric framework, set targets, build dashboards, review results monthly with team leads and the CDO, and integrate quality metrics into the team KPI framework;
• Shift the QA organization from reactive to proactive: involve QA at the requirements and design stages, implement risk-based test planning, and focus on regression prevention instead of regression firefighting;
• Drive test automation: define the automation roadmap, grow the AQA function, prioritize automation areas (regression, smoke tests, payment-critical flows), integrate automation into release pipelines, and measurably reduce manual testing quarter over quarter;
• Introduce AI tooling into daily QA workflows: select tools, run pilots, train the team, and measure impact on throughput and test coverage;
• Manage the QA organization: conduct performance reviews and grading, balance workload across teams, improve time-logging discipline, address overtime issues, and build hiring and growth tracks for QA leads;
• Improve product stability: own escaped-defect analysis, drive root-cause investigations with development leads, and reduce reopen rates in the weakest-performing teams;
• Continuously optimize QA processes through regular retrospectives and quarterly improvement goals with measurable outcomes.
  
  🧠 Nice to have:
• iGaming / gambling / betting domain experience (platforms, game providers, payment integrations, multi-brand setups);
• Payments/fintech testing background (transaction flows, PSP integrations, reconciliation);
• Hands-on coding skills sufficient to review AQA framework decisions (JS/TS, Python, or Java);
• Experience introducing QA metrics into bonus/KPI systems while maintaining team trust.
