About the role

  • As a Software Engineer Intern, you’ll build systems that power real-time, AI-driven customer interactions in contact centers. You’ll work on production infrastructure where latency, reliability, and measurable business outcomes matter
  • You may work across key areas such as:
  • AI Agents & Automation – systems that handle and assist high-volume customer conversations
  • Real-Time Agent Assist – delivering live guidance and insights during interactions
  • Conversation Intelligence – extracting insights from millions of conversations
  • AI Evaluation & Reliability – improving quality, consistency, and observability of LLM systems
  • Platform & Infrastructure – enabling scalable, low-latency AI experiences
  • Cresta’s platform powers the full contact center workflow—from real-time assistance and automation to post-call analytics and continuous optimization
  • You’ll operate in a high-ownership, fast-moving environment where interns are expected to contribute meaningfully, not just observe
  • Design and build systems that support real-time AI-powered customer interactions
  • Work on features combining LLMs, data systems, and user-facing applications
  • Collaborate with engineers, product, and ML teams to ship production-ready solutions
  • Build systems for evaluation, monitoring, and continuous improvement of AI behavior
  • Optimize for low latency, high throughput, and reliability at scale
  • Take ownership of problems end-to-end—from identifying gaps to shipping solutions
  • What You’ll Learn:
  • How to build and ship production-grade AI systems used in real customer environments
  • How to design systems balancing model quality, latency, and reliability
  • How AI agents are deployed, evaluated, and improved at scale
  • How contact centers evolve from manual workflows to AI-driven operations
