About the job


Machine Learning Engineer

We’re partnering with a fast-growing AI company building systems that automatically optimise digital marketing performance for consumer brands.


Their platform replaces manual campaign management with ML-driven optimisation engines — continuously improving performance, allocating budget in real time, and directly driving revenue.

They’re now hiring a Machine Learning Engineer to help design and scale the core models behind the platform.


This is a role where your models don’t sit in notebooks — they run in production, make decisions in real time, and have a measurable impact on business outcomes.


The Opportunity

You’ll work on applied ML problems at scale, including:

  • forecasting and time-series modelling
  • experimentation and causal inference
  • optimisation and decision-making systems


You’ll own problems end-to-end — from framing and modelling through to deployment and iteration — in a fast-moving, product-driven environment.


What You’ll Be Doing

  • Build and deploy ML systems that optimise large-scale advertising spend in real time
  • Develop models across forecasting, experimentation, and optimisation use cases
  • Design systems that make continuous, data-driven decisions under uncertainty
  • Collaborate with product and engineering to translate complex problems into scalable solutions
  • Own the full ML lifecycle: research → production → iteration


What They’re Looking For

  • Experience building and deploying ML models in production environments
  • Strong grounding in statistics, optimisation, or applied machine learning
  • Comfortable owning problems end-to-end with minimal structure
  • Pragmatic, impact-driven mindset — focused on real-world performance, not just model metrics


Why This Role Stands Out

  • Your work directly drives revenue for global consumer brands
  • Real-world ML challenges at scale — not just offline modelling
  • High ownership: you’ll take problems from idea to production
  • Strong engineering culture with a focus on shipping and iteration
  • Competitive compensation and meaningful equity


Who This Is For?

This role suits engineers who:

  • Want to work on applied ML with clear business impact
  • Enjoy solving optimisation and decision-making problems
  • Prefer shipping models to production over pure research
  • Like working in fast-paced, product-focused environments
