## Job description

## About Simple

[Simple AI](http://usesimple.ai) is building state-of-the-art voice AI agents for enterprise. Our realistic agents help iconic businesses like Doordash, xAI, and Omaha Steaks handle all kinds of phone operations, from customer support to order intake to lead qualification. We’re growing revenue like crazy and looking to hire a Senior Sales Development Representative (Senior SDR) to help accelerate outbound growth and open new markets. We are very excited about the potential for AI to change the world, and work out of our SF office. Simple AI raised $14M from world-class investors and operators like Y Combinator, First Harmonic, Massive Tech Ventures, Michael Seibel, Jared Friedman, Alexandr Wang, Matt Van Horn, Suhail Doshi, and Scott Wu.

The Team The founders ([Catheryn](https://www.linkedin.com/in/catherynli/) and [Zach](https://www.linkedin.com/in/zach-kamran/)) met while running software teams at YC, where they shipped tons of new products for YC founders, including YC’s co-founder matching site. Cat previously worked at Instagram and Facebook and earned degrees in math and computer science at MIT. Zach previously studied computer science and statistics at U Chicago and led software at PEAK6. We have grown into a strong team of 20+ and are continuing to scale quickly.

## About the Role

We are looking for a Senior SDR with 2+ years of SDR or BDR experience to help build the top of our sales funnel from the ground up. You will be responsible for researching target accounts, writing outbound messages, cold calling prospects, qualifying interest, and booking meetings for the sales team. This is a hands-on, high-activity role for an experienced outbound seller. You will work closely with the GTM team to test messaging, learn which buyers respond, understand different verticals, and help create the early outbound playbook for Simple. The best fit for this role is someone who is energetic, competitive, resilient, and excited to spend a lot of time on the phone. You should be comfortable with rejection, eager to improve quickly, and motivated by owning outbound pipeline and improving results at a fast-growing AI startup.

## What We Offer

- Competitive salary & meaningful equity
- Employee-friendly equity terms
- An office located in SF
- Health, dental & vision insurance
- Free lunch & dinner at the office
- Late night Ubers
- Regular team events & offsites

## What You'll Need

- 2+ years of experience in an SDR or BDR role, with hands-on outbound prospecting and cold calling.
- Strong written and verbal communication skills.
- A high level of energy, resilience, and comfort with rejection.
- Ability to stay organized and thrive in a fast-paced, ambiguous environment.
- Curiosity and genuine enthusiasm about AI and how businesses use it.
- Self-motivated, with the ability to independently manage prospecting, follow-up, and meeting generation.

## Nice To Have

- Experience doing outbound at an early-stage startup.
- Experience selling technical products or AI software.
- Familiarity with tools like HubSpot, Salesforce, Apollo, or Outreach.

If you’re excited to help build the foundation of a high-velocity outbound motion at an early-stage AI startup, we’d love to chat. Please note: At this time, Simple AI is unable to provide employment visa sponsorship for this role. We appreciate your interest and understanding.
