Software Engineer Intern

• 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

Benefits

• Weekly lunch & learn
• Work with an A+ team of ex-Founders, world leading scientists, and nationally competitive athletes
• Mentorship - A world class mentorship board advises and mentors our team-members to capture the opportunity ahead of us- Strong problem-solving ability and a bias toward action
• Strong proficiency in agentic coding workflows—effectively collaborating with AI tools to design, implement, and iterate—is a strong plus
• Interest in building user-facing products, backend systems, or real-time/data-intensive applications
• Familiarity with modern web development (frontend and/or backend), APIs, or system design fundamentals
• Experience with one or more programming languages (e.g., Python, Go, Java, JavaScript, TypeScript)
• Curiosity about LLMs, AI agents, or production AI systems (no prior ML experience required)
• A driver mindset—you proactively identify problems, take initiative, and push work forward rather than waiting for direction
• Experience using AI-powered developer tools (e.g., Cursor, Claude Code) to accelerate development workflows
• Understanding of building reliable, maintainable systems—this could include UI/UX quality, API design, or performance considerations
