Pricing Data Scientist

A global marketing-data organisation is upgrading the engine that matches millions of survey invitations to the right respondents. Your task: treat the matching pipeline as a full-scale optimisation problem and raise both accuracy and yield.

Responsibilities

• Model optimisation- refactor and improve existing matching/segmentation models; design objective functions that balance cost, speed and data quality.

• Experimentation- set up offline metrics and online A/B tests; analyse uplift and iterate quickly.

• Production delivery- build scalable pipelines in AWS SageMaker (moving to Azure ML); containerise code and hook into CI/CD.

• Monitoring & tuning- track drift, response quality and spend; implement automated retraining triggers.

• Collaboration- work with Data Engineering, Product and Ops teams to translate business constraints into mathematical formulations.

Tech stack

Python (pandas, NumPy, scikit-learn, PyTorch/TensorFlow)
SQL (Redshift, Snowflake or similar)
AWS SageMaker → Azure ML migration, with Docker, Git, Terraform, Airflow / ADF
Optional extras: Spark, Databricks, Kubernetes.

What you'll bring

• 3-5+ years building optimisation or recommendation systems at scale.

• Strong grasp of mathematical optimisation (e.g., linear/integer programming, meta-heuristics) as well as ML.

• Hands-on cloud ML experience (AWS or Azure).

• Proven track record turning prototypes into reliable production services.

• Clear communication and documentation habits.

Desired Skills and Experience

Experience & skills checklist

3-5 + yrs optimisation/recommender work at production scale (dynamic pricing, yield, marketplace matching).

Mathematical optimisation know-how - LP/MIP, heuristics, constraint tuning, objective-function design.

Python toolbox: pandas, NumPy, scikit-learn, PyTorch/TensorFlow; clean, tested code.

Cloud ML: hands-on with AWS SageMaker plus exposure to Azure ML; Docker, Git, CI/CD, Terraform.

SQL mastery for heavy-duty data wrangling and feature engineering.

Experimentation chops - offline metrics, online A/B test design, uplift analysis.

Production mindset: containerise models, deploy via Airflow/ADF, monitor drift, automate retraining.

Soft skills: clear comms, concise docs, and a collaborative approach with DS, Eng & Product.

Bonus extras: Spark/Databricks, Kubernetes, big-data panel or ad-tech experience.
