We are hiring two Software Developer Interns to join our team for a 10-12 week summer program. Interns will work alongside our developers on real client-facing projects - supporting Java-based add-ons, writing custom SSRS reports, and manipulating data out of MS SQL Server.

What You'll Do:
  • Write and optimize T-SQL queries, stored procedures, and views against MS SQL Server
  • Develop and maintain Java-based add-on products that extend Infinite Campus functionality

  • Strong attention to detail - our clients are school districts, and accuracy in reporting matters
  • Clear written communication for documenting work and interacting with the team
  • A genuine passion for learning - eager to pick up new tools, ask questions, and grow through hands-on work
  • Working conditions: part-time role, 20 hours per week, on-site in Hauppauge, NY; 10-12 week engagement beginning around May 2026
  • Preferred: experience with SSRS or any other reporting tool (Crystal Reports, Power BI, Tableau)
  • Preferred: exposure to MS SQL Server specifically (vs. MySQL/Postgres); familiarity with REST APIs or web services
  • Preferred: any background in or curiosity about K-12 education, edtech, or student information systems; or prior internship, co-op, or substantial personal project experience
