Original job description

Cresta unlocks the true potential of the customer experience, turning every conversation into a competitive advantage. Cresta’s unified AI platform combines conversational AI agents, real-time human agent augmentation, and comprehensive conversation intelligence to drive revenue and efficiency gains across every channel. The world’s leading companies, including United Airlines, Cox Communications, and Marriott, use Cresta to power world-class customer experiences every day.

Born from the Stanford AI Lab, Cresta has raised more than $270 million from the world’s leading investors, including a16z, Greylock, and Sequoia. Cresta’s leadership includes some of the leading minds in AI today. Our CEO, Ping Wu, founded and led Google's Contact Center AI and Vertex AI platforms before joining Cresta to build the future of AI-driven customer experiences.

Over the next few years, AI is going to redefine how people all over the world interact with businesses every day. Come build that future at Cresta.

Cresta is on a mission to turn every customer conversation into a competitive advantage by unlocking the true potential of the contact center. Our platform combines the best of AI and human intelligence to help contact centers discover customer insights and behavioral best practices, automate conversations and inefficient processes, and empower every team member to work smarter and faster. Born from the prestigious Stanford AI lab, Cresta's co-founder and chairman is Sebastian Thrun, the genius behind Google X, Waymo, Udacity, and more. Our leadership also includes CEO, Ping Wu, the co-founder of Google Contact Center AI and Vertex AI platform, and co-founder, Tim Shi, an early member of Open AI.

Join us on this thrilling journey to revolutionize the workforce with AI. The future of work is here, and it's at Cresta.

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.

This isn’t experimental AI. 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.

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.

What You’ll Do

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 We’re Looking For

Experience with one or more programming languages (e.g., Python, Go, Java, JavaScript, TypeScript)
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
Understanding of building reliable, maintainable systems - this could include UI/UX quality, API design, or performance considerations
Curiosity about LLMs, AI agents, or production AI systems (no prior ML experience required)
Experience using AI-powered developer tools (e.g., Cursor, Claude Code) to accelerate development workflows
Strong proficiency in agentic coding workflows - effectively collaborating with AI tools to design, implement, and iterate - is a strong plus
A driver mindset - you proactively identify problems, take initiative, and push work forward rather than waiting for direction
Strong problem-solving ability and a bias toward action

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

What Makes Cresta Different

AI in production: Our systems operate in live contact centers, not demos
Hybrid workforce: We’re defining how human and AI agents work together
Real business impact: We directly influence revenue, cost, and customer experience
Driver culture: We value people who take initiative, move fast, and own outcomes end-to-end
Ownership & velocity: Engineers are trusted to ship and make decisions early

Internship Details

Location: Toronto (remote-friendly; no in-office mandate, but we encourage in-person collaboration)
Compensation: CAD $30-50/hour
- Outstanding performers are eligible for return co-op and full-time offers well above our posted range.

Perks:

Lunch and dinner can be expensed (up to $25 each) while working in the office
Well-stocked office with snacks and drinks
Convenient downtown location near Union Station (public transit accessible)
PTO: 4 days
Exposure to cutting-edge AI systems in production
Potential return offer

Why Join

At Cresta, you won’t just learn about AI - you’ll help build the systems redefining how contact centers operate. From real-time agent assist to autonomous AI agents, your work will directly impact how millions of customer conversations are handled.

Past interns consistently highlight Cresta’s strong engineering culture and ownership-driven environment as a standout compared to their previous internship experiences. We invest in giving interns real responsibility, meaningful projects, and close collaboration with experienced engineers.

If you want to own real problems, ship quickly, and work at the frontier of applied AI, you’ll fit right in.

Application Note

To help us find the best team match, please include a brief note on the type of problems you most enjoy working on. For example:

Backend / distributed systems / infrastructure
Frontend / UI engineering / product experience
Full product development (end-to-end features)
AI / machine learning / applied LLMs
Data / analytics / experimentation
Or anything else you’d like us to highlight

We can’t guarantee specific team placement, but we use this input to help guide matching wherever possible.

This posting will be used to fill a newly-created role.

We have noticed a rise in recruiting impersonations across the industry, where scammers attempt to access candidates' personal and financial information through fake interviews and offers. All Cresta recruiting email communications will always come from the @cresta.ai domain. Any outreach claiming to be from Cresta via other sources should be ignored. If you are uncertain whether you have been contacted by an official Cresta employee, reach out to [email protected]
