About us:TyrAds is a leading tech-driven loyalty and rewards platform that partners with businesses to create meaningful and rewarding experiences for their customers.

We are hiring a Senior Data Scientist to work alongside our Product team and turn our reward economy into models the business can act on.
This is a quantitative modelling role, not a production ML role. Our machine learning engineering team owns real-time serving, latency and model monitoring. You define the model, you design the experiment that tests it, and you produce the measured result. They serve it.
The problems are commercial and they are hard. A single campaign can carry up to 50 rewarded events. Lower the payout on one of them and unit margin improves, users stop progressing, and advertiser revenue falls. Today those trade-offs are set by experience. Your job is to replace experience with measurement.
Job RequirementsModelling5+ years as a data scientist or quantitative analyst in a product, marketplace or performance marketing businessApplied statistics: experiment design, power analysis, confidence intervals, and the discipline to report a null result as clearly as a positive oneCausal inference beyond A/B testing: difference in differences, matching, holdouts, incrementalityTechnicalAdvanced SQL on large event tables (CTEs, window functions)Python for modelling and analysis (pandas, numpy, scikit-learn)Comfortable with the defects of real event data: duplicates, late arrivals, rejected installs,



inconsistent partner dataWays of workingCan explain a model to a commercial stakeholder without simplifying it into something that is no longer trueWorks well alongside a Head of Product and a COO who are both hands-on in the same problemsNice to HaveMobile advertising, user acquisition, offerwall or rewarded advertisingMMP data (AppsFlyer, Adjust) and the limits of multi-touch attributionPricing, incentive or elasticity modelling in a commercial settingDatabricks or SparkFraud and anomaly detectionJob ResponsibilitiesReward Economy ModellingModel payout against funnel progression, event design against completion, and user quality against advertiser returnProduce elasticity estimates that can be used to configure a campaign, not only to describe oneSize the opportunity in revenue or margin before the work startsExperimentationDesign controlled experiments: randomisation unit, power analysis, primary and guardrail metricsSet run time from the funnel's own event timing, and agree stopping rules before launchWrite a decision record for every experiment, including the ones that failCausal InferenceRun isolation reads before any causal claim, separating the effect of a funnel change from the effect of a change in publisher mixDifference in differences, matching, holdouts, incrementality testingSay clearly when the available data cannot answer the questionMaking It UsableHand models that go live to the ML engineering team with an evaluation specification they can serve againstWrite findings that AdOps and Sales can act on the same day, without a translation layerWhat this role is not:Not Production ML: API serving, latency, and drift are owned by ML Engineering.
Not Data Engineering: Pipelines are built and maintained by Data Engineering.
Not Dashboarding: Reports are a byproduct, not the core deliverable.
