Job description

About Eulerity
Eulerity is a rapidly growing technology company revolutionizing marketing automation for small businesses and franchises with our industry-leading proprietary software. Founded by leaders from Google, Facebook, and Yahoo! with more than 20 years of digital advertising, engineering, and marketing experience, we build tools that make enterprise-grade marketing accessible at scale.
The Role
We're looking for a Backend Developer with 1-3 years of experience to join our engineering team. You'll take an active role in building, testing, and maintaining the backend services that power our platform - and you'll do it with AI as a core part of your workflow, not an afterthought. This is a role for someone who's genuinely excited about what AI-assisted development makes possible and wants to push that further every day.
What You'll Do
  • Build, test, and maintain backend services across Eulerity's core platform
  • Own features end-to-end - from design and implementation through deployment
  • Use AI agents and LLM tooling to prototype, iterate, and ship faster
  • Contribute product ideas and help shape the engineering roadmap
  • Collaborate closely with cross-functional teams on features and releases
  • Assist with documentation, system support, and knowledge sharing across the team
About You
  • 1-3 years of hands-on backend development experience, with at least 1 year building in Java
  • You've actually used AI agents (Claude, Copilot, Cursor, or similar) to build, debug, and ship software - not just experimented with them
  • Familiarity with LLMs, AI agent frameworks, or AI-assisted development workflows
  • Comfortable integrating third-party APIs
  • A strong drive to keep learning - especially when it comes to evolving AI tooling and how it applies to real engineering problems
  • You think creatively about complex problems and enjoy finding elegant solutions
  • A collaborative, communicative team player with a friendly, low-ego approach
Requirements
  • Based in the NYC tri-state area
  • Available to work full-time (40 hours/week)
What We Offer
  • Competitive salary (commensurate with experience)
  • Full GitHub Copilot access with frontier LLMs and coding agents from Anthropic, Google, and OpenAI - so you're always working with the best tooling available
  • Mentorship and regular peer review sessions
  • Unlimited snacks and an in-office lunch credit
  • Hybrid work flexibility with at least three in-office days per week
Benefits
  • Comprehensive benefits
    • Medical
    • Dental
    • Vision
  • Unlimited PTO
  • Commuter benefits
  • 401(k) with company match
  • Summer Fridays
Compensation
Our salary ranges are based on paying competitively for our company's size and industry, and are one part of the total compensation package that also includes benefits, perks, and other opportunities at Eulerity. The expected total compensation range for this role is $95,000 - $115,000, commensurate with experience.
