ML Engineer

Since 1999, the company has expanded from listings into payments, shipping and seller financing. Hollowpath operates consumer websites and apps used by tens of millions of people each month. Founded in 1999, we now have 1,700 employees.

The role:

Hollowpath has an opening for an ML Engineer. ML engineering role focused on pipelines, serving and monitoring. You'll work alongside data scientists rather than replace them. Our headquarters is in Warsaw, and about a third of the team works remotely from other countries. This is a full-time remote role.

In this role you will:

• Orchestrate pipelines with Kubeflow, SageMaker Pipelines, Vertex AI or Airflow.
• Develop RAG pipelines with embeddings, vector stores (pgvector, Pinecone, Weaviate) and rerankers.
• Track experiments, artifacts and versions in MLflow or Weights & Biases.
• Deploy models behind low-latency APIs with FastAPI, Triton, TorchServe or vLLM.
• Cut inference cost with quantization, batching and caching.

Qualifications:

• 3-5 years of software engineering experience, with at least two spent on ML systems in production.
• BS or MS in computer science, engineering or a related field.
• Comfortable with SQL and large-scale data processing in Spark or Ray.
• Hands-on experience with PyTorch, TensorFlow or JAX.
• Familiarity with Docker, Kubernetes and a cloud ML platform (SageMaker, Vertex AI, Azure ML)
• Knowledge of LLM APIs, prompt design and evaluation methods.

Nice to have:

• Published papers or open source ML contributions.
• CUDA or Triton kernel experience.

Rate: XOF 1,500,000 to XOF 1,800,000/month
