Software Engineer Intern
About The Position
Cresta is building the AI platform for the modern contact center—one of the largest and most critical systems in the global economy. We combine human agents and AI agents to handle customer conversations at scale, helping enterprises improve customer experience, increase revenue, and reduce cost in real time. Our systems run in live production environments, shaping millions of customer interactions every day. We’re looking for builders who want to take ownership and move fast. 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.
