Requirements
  • 5+ years building ML infrastructure, data pipelines, or ML systems in production
  • Strong Python skills and expertise in PyTorch or JAX
  • Hands-on experience with data pipeline technologies (e.g., Spark, Airflow, BigQuery, Snowflake, Databricks, Chalk) and schema design

  • Track record of building scalable data systems and shipping production ML infrastructure
  • Ability to move quickly and handle competing priorities in a fast-paced environment
Responsibilities
  • Build and optimize distributed ML infrastructure for training foundation models on large-scale medical imaging datasets.
  • Design and implement robust data pipelines to collect, process, and store large-scale multimodal medical imaging data from both production traffic and offline sources.
  • Build centralized data storage solutions with standardized formats (e.g., protobufs) that enable efficient retrieval and training across the organization.
  • Create model inference pipelines and evaluation frameworks that work seamlessly across research experimentation and production deployment.
  • Collaborate with researchers to rapidly prototype new ideas and translate them into production-ready code.
  • Own end-to-end delivery of ML systems from experimentation through deployment and monitoring.
Desired Qualifications
  • Experience with reinforcement learning training pipelines (e.g., RLHF, reward modeling, or online learning systems)
  • Support A/B testing and experimentation workflows for model rollouts, including monitoring statistical significance and managing canary deployments.
  • Familiarity with vision-language models (VLMs) or multimodal architectures
  • Experience with medical imaging formats (DICOM) and healthcare data standards
  • Background in distributed training frameworks (PyTorch Lightning, DeepSpeed, Accelerate)
  • Familiarity with MLOps practices and model deployment pipelines
  • Experience with privacy-preserving data systems and HIPAA compliance

Simplify's Take

What believers are saying

  • Localized Japanese small-business digitalization can drive steady demand.
  • Broader service scope enables bundled projects and recurring maintenance revenue.
  • California and UK-facing footprints can support international partnerships and client acquisition.

What critics are saying

  • Brand confusion with larger Epsilon businesses will distort search traffic and inbound leads.
  • Small-team capacity makes delivery fragile under illness, turnover, or simultaneous projects.
  • Crowded low-friction agency markets compress pricing and weaken recurring revenue.

What makes Epsilon Health unique

  • Oiso Town-based small digital production company serving businesses and individuals.
  • Offers websites, apps, and games under one cross-functional delivery model.
  • Provides support from consultation through post-release operation for long-term client retention.
