• Bachelor’s degree in computer science, engineering or a related field (or equivalent practical experience).
• Background in healthcare, life sciences, or clinical data.
• Experience with cloud platforms (AWS, GCP, or Azure) and working in cloud-native environments.
• Strong problem-solving and communication skills.
• Ability to work independently and manage tasks with moderate supervision.

Nice to Have

• Experience in R package development, SQL, Python, version control and CI/CD tools (e.g., GitLab, GitHub Actions).
• Familiarity with software validation practices for regulated or regulatory-grade environments.
• Experience working with or developing machine learning pipelines or models.
• Exposure to Generative AI or LLM frameworks (e.g., Langchain, LangGraph).
• Knowledge of distributed computing concepts or tools (e.g., Spark, Dask).
• Knowledge of command-line workflows in UNIX/Linux environments.

What We Offer

• Hybrid work environment – 3 days onsite per week.
• Comprehensive health, dental, and vision coverage for you and your family.
