About the Role
Vielight is looking for a full-stack developer to improve and scale an existing clinical EEG platform.

You will collaborate with our designers and computational neuroscientist while owning the technical implementation and integration of the overall platform.
Responsibilities

  • Improve system architecture, performance, reliability, and maintainability

  • Improve testing, deployment, monitoring, and developer workflows

What We’re Looking For

  • Strong professional experience with full-stack web development
  • Proficiency in Python, Django, React, and TypeScript
  • Experience working with asynchronous pipelines, background workers, and APIs
  • Knowledge of event driven design
  • Strong understanding of databases, Docker, Linux, and production deployments
  • Ability to understand and improve an existing system—not only build new features
  • Practical judgment, attention to quality, and clear communication

Technical Environment
React, TypeScript, Python, Django, FastAPI, PostgreSQL, Celery, RabbitMQ, Redis, Docker, and cloud-based infrastructure.

Pay: $100,000.00-$120,000.00 per year
