Help design AI agents and workflow automations that streamline repetitive processes across the organization.

Create and maintain data pipelines and foundational infrastructure needed to support ML / AI experimentation and deployment.

Partner cross-functionally to test ideas quickly, evaluate outcomes, and refine solutions based on business value.

What You Bring to the Team

Required:

Bachelor’s degree in computer science, data science, mathematics, or a related technical field, or equivalent practical experience.

1–3 years of professional or research experience in ML, AI engineering, or data science; coursework, bootcamp work, and independent projects may be considered alongside professional experience.

Git / version control proficiency.

Strong grounding in statistics and probability fundamentals.

Strong Plus:

LLM integration experience using platforms such as OpenAI or Anthropic.

RAG pipelines and familiarity with LangChain or LlamaIndex.

Docker and experiment tracking tools such as MLflow or Weights & Biases.
