  • Familiarity with containerization technologies such as Docker and orchestration tools like Kubernetes.
  • Solid understanding of RESTful APIs and asynchronous programming patterns.
  • Strong experience with SQL databases (e.g., Microsoft SQL Server, MySQL, PostgreSQL), including schema design and query optimization.
  • Self-starter, comfortable with ambiguity, ability to initiate and reliably drive projects forward with minimal oversight
  • Excellent problem-solving skills and the ability to work effectively within cross-functional teams.
  • Ability to communicate effectively with both technical and non-technical stakeholders
  • Ability to work in the Chicago office periodically is required
