Retell AI Basics: Everything You Need to Start Building Voice Agents

Why This Company

Twenty years ago, every business found itself needing a website, the new gateway to the world. Platforms like WordPress and Squarespace rose to become the standard for getting businesses online.

Today, we’re at the start of a new shift. Every business that relies on phone interactions can now have an AI voice agent of their dreams. A tireless and empathetic receptionist, salesperson, debt collector, or appointment reminder that works 24/7. Operational bottlenecks vanish overnight. Doubling your business no longer means doubling your team. Customer experience no longer suffers. (Ever tried calling an East Coast bank after 3 p.m. PT?) But companies aren't ready. Platforms don't exist.

At Retell, we're building the new standard for building AI voice agents. A seamless UI, a comprehensive toolkit, effortless integrations, and a thriving builder community, we're creating everything businesses need to deliver exceptional phone interactions on every single call.

This shift is happening, so why not be part of the team that defines it?

• Recruit the Best Talent – Own and continuously improve our recruiting process for all roles. Source candidates, schedule interviews, draft offers, and manage relationships with external recruiters. Identify and eliminate bottlenecks in the hiring funnel.

Our Compensation Philosophy

• Our Strongest Offer, Upfront
  We give you our best offer from the start. No need to negotiate or match other companies offer — instead, we offer three clear compensation options, each with a different balance of cash and equity. You pick what fits you best.
• Designed for Talent Density
  We’re building with the top 1%, not the average. That’s why our compensation is set far above market — to attract people who raise the bar for everyone around them.
• Scale Through Code, Not Headcount
  We aim for >$1M in revenue per employee. That means smaller teams, fewer layers, and higher ownership per person — both in terms of scope and equity.
• Performance > Background
  We don’t anchor to other companies, past salaries, or industry ranges. Your offer is based entirely on your performance in our interview process. That’s it.
• Experience Doesn’t Dictate Pay
  Your offer is based solely on how well you perform in the interview process. We don’t factor in past salaries, titles, or number of years worked. You can earn our highest tier with zero years of experience — if you prove you’re ready for it.

Interview Process

• Introduction – We’ll kick things off by getting to know each other—sharing backgrounds and answering any questions you have about the role. The session wraps up with a mini mock project: three research questions to prepare for the next stage.
• Phone Interview 1 – A 30-minute conversation focused on communication, conflict resolution, and judgment. We’ll work through a hypothetical scenario together using a shared document.
• Phone Interview 2 – A 30–45 minute session centered around tool usage. You might be asked to demonstrate how you’d use a SaaS tool to build automations or improve efficiency within a company.
• Onsite Interviews – These take 1–4 hours and are conducted in person in the San Francisco Bay Area. For remote candidates, we’re happy to arrange virtual sessions. Please bring a computer for any hands-on portions. There are up to two rounds:
  • Practical session to assess your organizational skills, prioritization, and workflow design
  • Research session where you’ll explore a product and walk us through your thinking, communication style, and product sense
