Job Description:

 Model development produces experiments, checkpoints, evaluation results and many versions of the same model. Keeping those records connected lets engineers reproduce results, compare approaches and move a trained model into use. 

We are looking for a Senior Software Engineer to build the backend services that make those workflows reliable. You will connect training runs to their data, code and configuration, manage model artifacts and help machine-learning engineers spend less time reconstructing what happened in an experiment. 

What you'll do:

  • Build experiment-tracking and model-registry services, integrating tools such as MLflow where appropriate. 

  • Connect exact dataset, code and configuration versions to training runs, checkpoints and model versions. 

  • Develop APIs and adapters that connect training jobs, data services and artifact storage. 

  • Make interrupted or failed workflows recoverable through reliable state handling, retries and useful diagnostics. 

  • Make checkpoints, model artifacts and evaluation results easy to find and retrieve for further training, evaluation or deployment. 

  • Work directly with machine-learning engineers to simplify their workflows and reduce manual record keeping. 

  • Deliver tested services with observability and compatible upgrades across supported cloud and customer-managed environments. 

Key Outcomes:

  • Engineers can trace a model version back to the data, code, configuration and run that produced it. 

  • Checkpoints and evaluation evidence remain available when jobs fail or workflows change. 

  • Developers can compare experiments and retrieve model artifacts through consistent APIs. 

  • Teams can reproduce results without manually reconstructing experiment history. 

Required qualifications:

  • Experience building production backend services for machine-learning platforms or data-intensive workflows. 

  • Strong software engineering skills in Python or a comparable backend language. 

  • Experience designing APIs, metadata models and persistent state for services used by other engineers. 

  • Experience handling storage, partial failures, retries and consistency in distributed systems. 

  • Understanding of training runs, checkpoints and model versioning. 

  • Ability to work directly with machine-learning users and deliver maintainable software that solves their workflow problems. 

Preferred qualifications:

  • Experience with MLflow, Weights & Biases, model registries or comparable experiment-management tools. 

  • Experience integrating Kubernetes jobs, object storage or machine-learning workflow systems. 

  • Experience with reproducibility, data provenance or evaluation records. 

  • Experience supporting open-source software or on-premises and air-gapped deployments.
