Required Experience

  • Bachelor's degree in Computer Science or a related field (or equivalent experience)
  • 5 years of software engineering experience
  • 2 years delivering production-grade machine learning solutions
  • Strong proficiency in Python and its ecosystem
  • Experience building clean, maintainable, and well-tested code
  • Proven ability to quickly adopt new technologies to solve complex challenges
  • Experience working closely with data science teams to productionize research
  • Hands-on experience with cloud environments (preferably AWS)
  • Familiarity with Agile methodologies, CI/CD, DevOps, and SDLC best practices
  • Strong interest in practical applications of machine learning

Preferred Experience

  • Experience integrating ML models into production systems (e.g., scikit-learn, XGBoost)
  • Exposure to big data platforms (e.g., Snowflake) and scalable SQL
  • Understanding of MLOps / ModelOps principles
  • Experience with entity matching or entity resolution at scale
  • Ability to bridge research and engineering workflows effectively
  • Experience with additional programming languages (e.g., Java, Scala, Rust, TypeScript)

If you're a hands-on engineer who enjoys turning cutting-edge research into production-ready systems, this is an excellent opportunity to make a measurable impact.
