ABOUT RETELL AI
Retell AI is using first principles to reimagine the call center with cutting-edge voice AI.
Thousands of companies now utilize Retell’s AI voice agents to handle sales, support, and logistics calls that once required large teams of human agents. Backed by Y Combinator, Alt Capital, and other leading investors, we have scaled to $60M ARR with a team of 40 people, up from $5M at the start of 2025.
Our vision for 2026 is to build a modern CX platform where entire contact centers are powered by AI. Instead of basic automation that needs constant human tuning, we’re creating intelligent AI “workers” that can act as frontline agents, QA analysts, and managers — continuously executing, monitoring, and improving customer interactions.
We’re growing quickly and looking for ambitious builders who want to tackle hard technical problems, move fast, and have real impact at one of the fastest-growing voice AI startups.
Let’s build the future together.

ABOUT THE ROLE
We're looking for a Marketing Intern who wants to learn how startup marketing actually works.
This isn't the type of internship where you'll spend your summer making slide decks or sitting in meetings. You'll work directly with our marketing and leadership teams on real projects that help drive company growth.
You'll get exposure to a wide range of marketing functions and have the opportunity to figure out what you enjoy most—whether that's content, growth, product marketing, events, social media, community building, or something else entirely.
If you're curious, creative, and excited about AI, you'll have the chance to make a real impact while learning how one of the fastest-growing startups operates from the inside.
WHAT YOU'LL WORK ON
Creating content for LinkedIn, blogs, newsletters, and other channels
Supporting product launches and marketing campaigns
Researching competitors, customers, and market trends
Helping build and execute SEO initiatives
Assisting with events, conferences, and community programs
Developing customer stories, case studies, and testimonials
Supporting recruiting and employer branding efforts
Experimenting with growth and demand generation projects
Working on special projects directly with company leadership
No two weeks will look exactly the same.

Current undergraduate or graduate student, or recent graduate
Located in the Bay Area and able to work onsite in Redwood City
Strong communication and writing skills
Interested in marketing, startups, technology, AI, or business
Highly organized and detail-oriented
Comfortable taking ownership and figuring things out independently

BONUS POINTS
Experience creating content for social media, blogs, newsletters, or websites
Familiarity with tools like Canva, Figma, HubSpot, Notion, Clay, or ChatGPT
