Senior ML Engineer

Advertising, subscriptions and transaction fees each bring in a significant share of revenue. Traffic during holiday peaks can reach ten times normal levels, and the platform is built for it. We started in 1996 and have grown to about 109,600 people.

About the role:

This is a new role. The team has doubled in size over the past year. This hire will help build out our ML platform: feature store, training pipelines, model registry and deployment. This is a full-time remote role. We use an employer of record in the US, so you get a proper employment contract, not a freelance agreement. Core hours are 10:00 to 15:00 CET.

Main duties:

• Write clean, tested Python and review teammates' code
• Track experiments, artifacts and versions in MLflow or Weights & Biases
• Fine-tune open-weight models with LoRA when it beats prompting
• Maintain feature pipelines and a feature store such as Feast or Tecton
• Productionize data science prototypes without rewriting everything
• Monitor models for drift, data quality issues and latency regressions

Required qualifications:

• 5+ years of software engineering experience, with at least two spent on ML systems in production
• Strong Python and solid engineering habits (testing, packaging, code review)
• Familiarity with Docker, Kubernetes and a cloud ML platform (SageMaker, Vertex AI, Azure ML)
• Understanding of core ML concepts: overfitting, evaluation metrics, bias in training data
• Knowledge of LLM APIs, prompt design and evaluation methods
• Hands-on experience with PyTorch, TensorFlow or JAX

$225,000 to $280,000 a year

Compensation and benefits:

• Paid parental leave
• 20 days paid time off
• Performance bonus
• Health insurance through our employer-of-record partner
• Annual team retreat
• Company laptop

We are an equal opportunity employer. If you need an accommodation during the application process, let us know.
