We are looking for a Senior Product Analyst within the “Search & Recommendations” domain, working closely with ML engineers, software developers, and product managers. You will be supported by a strong analytics team that you can tap into for complex challenges, as well as a sophisticated internal tooling stack: an in-house A/B experimentation platform, a proprietary conversational analytics tool, a suite of MCPs and AI agents for routine workflows, high-quality data in BigQuery and Spark, and a transparent ETL pipeline built with Airflow and dbt.
This role is for someone who wants to be an owner of metrics and a driver of decisions within the domain: rethinking what “good search” means for us (from relevance to search success), independently uncovering insights and driving ideas all the way to production.
Responsibilities
- Develop and maintain a hierarchy of product metrics for Search & Recommendations (ensuring they are accurate, clearly understood by the team, and truly reflect product quality)
-
Design, launch, and interpret A/B tests; improve tooling and automation around experiment analysis
-
Conduct product research (identify growth opportunities, answer high-level questions, and formulate hypotheses for the team)
-
Analyze user behavior patterns and independently uncover insights that are meaningful for the product
-
Influence goal setting and project prioritization within the team based on data
-
Develop self-service capabilities in the domain (structure data to make it easily usable by AI tools, and automate routine analysis so the team can independently answer basic questions)
Requirements
- Strong knowledge of mathematical statistics and hands-on experience with A/B testing
-
Strong SQL skills and basic Python proficiency
-
AI-native mindset: you automate your own workflows using AI and are ready to building pipelines and agents
-
Ability to solve non-trivial problems under conditions of incomplete data
-
Curiosity and a habit of asking the right questions (probing what lies behind a metric and not being afraid to challenge the team)
-
Proactivity and ready to take ownership (choosing which metrics matter, where the product should evolve and which hypothesis to test next)
-
Strong attention to detail and a habit of following through to completion
Preferred
- Experience in search, recommendations, ML-driven products, or e-commerce
-
Understanding of ML fundamentals
-
Experience building AI pipelines and agents
We offer
- Compensation package: base salary and performance-based bonuses
-
Office-first: flexible hours with a possibility to work remotely 52 days per year
-
Care & Wellbeing: health insurance (including dental care) for employees and their children, daily meal allowance, and 100% paid sick leave
-
Relocation Support: full assistance for a smooth relocation for the employees and their family
-
Team & Growth: collaboration with colleagues across Portugal, Brazil, Latvia and China, with opportunities for promotions, professional trainings, and English & Portuguese courses
-
Community & Engagement: annual team building activities, knowledge-sharing workshops, and a strong sense of team work
