Senior Product Analyst - Rewarding Systems (all genders)

JustPlay is looking for a Senior Product Analyst to join the team. You’ll work closely with the Rewarding team, investigating how rewards impact retention and engagement. You will analyse user behaviour to understand what drives retention using correlational analysis and ML techniques, and simulate user journeys at scale. You will create frameworks, metrics and visualisations to quantify relevant signals, and design and manage the experimentation roadmap to improve our player experience.

We're looking for someone who's passionate about using mathematical methods to solve business challenges and thrives on tackling complex, ambiguous problems to drive measurable impact. You'll need to take initiative and work proactively, bring creativity to your problem-solving approach, and be eager to go beyond the numbers to truly understand what makes our players tick.

Job Requirements

• Advanced degree in Math, Stats, Econometrics or similar scientific domain, or a bachelor degree with experience equivalent to advanced degree

• At least 5 years of experience in an analytics role as a product analyst or data scientist focusing on consumer-facing products. Candidates with 3 years experience plus an advanced degree with relevant practical research thesis will also be considered

• Experience conducting complex correlational analysis (stickiness analysis, churn analysis and detection, VIP analysis, fraud analysis)

• Proficient in SQL and Python, including packages such as Pandas and Numpy

• Experience with Machine Learning techniques for segmentation (K-means, clustering), regression, and classification

• Experience solving complex optimization problems using analytical methods and/or learning systems

• Comfortable conducting statistical analysis and modeling using statistical best practices

• Experience defining and implementing metrics and building visualisations using BI platforms such as Looker, Tableau, or Metabase

• Hands-on experience with data warehouses such as BigQuery or Snowflake

• Strong attention to detail and ability to interpret complex data

• Excellent communication skills and proven experience collaborating with business stakeholders

• Experience with Monte Carlo simulations, Multi-Armed Bandit algorithms, XGBoost, SVD, or similar advanced techniques is a plus

• Experience managing gaming economy or pricing for a B2C product is a plus

This job is not for you if

• You don’t like solving complex problems

• You don’t mind doing analyses whose results will be ignored

• You don’t care about business goals and measuring impact

• It doesn’t bother you to build tools that no one will use

• You’re comfortable using methods without understanding the science behind them

• You are not looking for an environment that challenges you

• You don’t ask challenging questions

But if you love diving deep into complex data challenges and seeing your analysis drive real product decisions, we'd love to hear from you!

Job responsibilities

• Simulate user behaviour using tools such as Monte Carlo simulations to model player journeys at scale

• Use Machine Learning algorithms for user segmentation, regression and classification tasks

• Create frameworks and metrics that quantify the relationship between rewards, retention and engagement, with clear visualisations

• Deep dive into user behavioural data to unearth patterns and inflection points connecting rewarding and engagement

• Conduct churn analysis and create a churn propensity score

• Plan, define, conduct and evaluate A/B tests to drive experimentation-led product development. Manage the testing roadmap

• Think creatively to find optimal solutions to complex, often unstructured problems

• Collaborate with Engineering teams to define the data we need to collect for optimal outcomes
