Job description

Eulerity is a rapidly growing technology company revolutionizing marketing automation for small businesses and franchises with our industry-leading proprietary software. We were founded by leaders from Google, Facebook and Yahoo! with more than 20 years of digital advertising, engineering and marketing experience.
Your Role:
  • Take an active role in developing, testing, and maintaining our backend services - leveraging AI agents to accelerate and improve your work
  • Implementing new features, starting from design to deployment
  • Help come up with new features and product ideas, using AI tooling to prototype and iterate quickly
  • Collaborate with other teams on features and releases
  • Assist with the preparation of documentation, training, and support of various systems

About You:
  • You have at least 1 year of hands-on experience working with AI agents (e.g. Claude, Copilot, Cursor, or similar coding agents) to build, debug, and improve software
  • Experience with LLMs, AI agent frameworks, or AI-assisted product development (you've actually used these, not just read about them)
  • At least 1 year of experience building backend solutions with Java
  • You have a strong willingness to continuously learn, experiment with, and deepen your knowledge of AI tools and how they can be applied to real engineering challenges
  • You understand how to use agents and LLMs to find the right resources, generate and review code, and solve problems more effectively
  • You enjoy coming up with creative solutions to complex problems
  • Comfortable working with third-party APIs
  • Able to work in conjunction with other team members

Requirements:
  • Currently a student graduating in Dec 2026 or later
  • Based in the NYC tri-state area
  • Able to commit minimum 30 hours per week

Benefits:
  • Pay $17-$19/hour
  • Mentorship with regular peer review sessions
  • Free lunch and unlimited snacks
  • Full GitHub Copilot access with frontier LLMs and coding agents from Anthropic, Google, and OpenAI - keeping you equipped with the best AI tooling available

Internship Details:
  • The internship will run from May until August with potential to extend based on candidate performance + availability
  • Hybrid work flexibility provided with in-office expectations at least twice per week
