Role description
π¨ Principal Data Science Lead | Fully Remote | $30/hr | 12-Month Contract
Iβm currently working with a client looking for an experienced Principal Data Science Lead to take a strategic and hands-on role in developing advanced analytics for an innovative marketing investment allocation platform.
This is a great opportunity for someone with deep expertise in Bayesian modelling, Marketing Mix Modeling (MMM), and PyMC who can combine technical leadership with hands-on data science.
π° Rate: $30/hour
π
Contract: 12 months
π Extension: Strong potential for extension
π Location: Fully Remote
π Location Eligibility: South American candidates are strongly encouraged to apply, and US-based candidates are also being considered.
πΉ What Youβll Be Doing
β’ Lead and shape the modelling strategy for an advanced marketing investment platform
β’ Develop and oversee complex Bayesian statistical models
β’ Build generative models using PyMC and Bayesian inference
β’ Apply Marketing Mix Modeling (MMM) to measure marketing investment impact
β’ Use Bayesian methods for uncertainty quantification and forecasting
β’ Establish best practices around model validation, including posterior predictive checks
β’ Provide hands-on technical leadership across advanced analytics initiatives
β’ Work closely with marketing, data, and business stakeholders
β’ Help establish and maintain strong data governance and security practices
πΉ What Weβre Looking For
β’ 10+ years of experience in Data Science, including leadership experience
β’ 5+ years working with Bayesian statistical modelling and machine learning
β’ Strong experience applying data science to marketing ROI / marketing analytics
β’ Strong hands-on experience with Python and PyMC
β’ Experience with Bayesian Hierarchical / Mixed Models
β’ Strong understanding and practical experience with Marketing Mix Modeling (MMM)
β’ Experience developing predictive analytics solutions at scale
β’ Strong understanding of data governance
β’ Experience leading teams and providing technical direction
β’ Experience with Microsoft Azure is highly desirable
β’ MS or PhD in Data Science, Statistics, Computer Science, or a related discipline
β Ideal Background
We're particularly interested in candidates who aren't purely strategic. This role requires someone who can operate at Principal level while still getting hands-on with Python, PyMC and advanced Bayesian modelling.
π South American data science professionals are especially encouraged to apply, while we're also open to qualified candidates based in the United States.
If you have a strong background in Bayesian modelling + MMM + PyMC and you're open to a long-term contract opportunity, I'd be keen to connect.
π© Send me a message or apply directly to discuss the opportunity.
