Customer Success Engineers (CSEs) are professionals who help clients maximize the value of a company's technical products or services. They combine technical expertise with strong communication skills to assist customers in onboarding, troubleshooting, and achieving their business goals using the product.

Job description

ABOUT RETELL AI
Retell AI is using first-principles thinking to reimagine the call center with cutting-edge voice AI. Thousands of companies now use 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've scaled to $80M in ARR with a team of 50, up from $5M at the start of 2025, and are now valued at over $1.5B.
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 act as frontline agents, QA analysts, and managers, continuously executing, monitoring, and improving every customer interaction.
We're growing fast and looking for ambitious builders who want to tackle hard technical problems, move quickly, and have a real impact on one of the fastest-growing voice AI companies in the world.
Let's build the future together.

ABOUT THE ROLE
Retell AI transforms customer experience with voice AI for enterprises, including customers like CVS/Aetna, American Airlines, Lenovo, and Grab. We have more customer stories than we can tell!
We're hiring a Customer Success Engineer to help our enterprise customers successfully deploy and scale AI voice agents in production.
You'll become the technical partner for our customers, helping design integrations, troubleshoot deployments, build AI workflows, and ensure customers are successful from onboarding through expansion.
This role sits at the intersection of software engineering, customer success, and AI deployment. You'll work closely with Engineering, Product, and Customer Success while partnering directly with customer engineering teams.
This is a full-time, long-term W-2 contract position with the opportunity to make a significant impact at one of the fastest-growing AI companies. While the role is primarily based in our Redwood City office, we're open to remote candidates with strong Customer Success Engineering experience and exceptional technical backgrounds.

WHAT WE'RE LOOKING FOR
Must Have

  • One of the following:
    • 5+ years of experience in Customer Success or as a Customer Success Engineer at a B2B software company.

  • Startup experience.

  • Travel: Willingness to travel up to 10% for enterprise customer launches, onsite workshops, and customer Innovation Day events.
