This Role Is Not for Everyone

If you're looking for a 9-to-5 or a job that follows a playbook, this probably isn't for you.

But if you're hungry to sell a truly differentiated product, obsessed with learning, and want to be in the room as an early-stage team builds something category-defining, read on.

We’re an AI startup backed by top operators and investors, building technology that replaces the most time-consuming part of hiring — the first-round interview. Our system conducts live, real-time interviews autonomously, asking personalized follow-ups based on each candidate's answers. It’s already replacing hours of human screening for fast-scaling companies across multiple industries.

We’re hiring a founding SDR to help us scale even faster. This is not a list-scraping, script-reading role. You'll work directly with the founding team to craft strategy, break into new accounts, and help define what outbound looks like when you're creating a category — not following one.

What You’ll Be Doing

• Own outbound outreach across email, cold calls, and social to drive pipeline

• Work directly with the founding team on messaging, sequences, and target segmentation

• Engage, qualify, and book high-quality meetings with decision-makers

• Build, manage, and optimize your pipeline using tools like HubSpot and Apollo

• Become a subject matter expert on AI in recruiting and hiring

• Contribute ideas, systems, and outbound experiments — and learn fast from the results

Who You Are

• 0–2 years of relevant experience (sales, recruiting, customer success, or something similar)

• Strong communicator with natural curiosity and confidence

• Relentlessly resourceful — you figure things out and take initiative

• Not afraid of cold outreach or rejection

• Interested in startups, AI, and the future of work

• Based in San Francisco or willing to relocate (5 days/week in person required)

• Authorized to work in the U.S. (no sponsorship provided)

Compensation & Benefits

Compensation Structure:

• Competitive base salary & uncapped commissions

• Early-stage equity in a high-growth AI company

Perks & Benefits :

• Health, dental, and vision insurance

• Generous PTO and paid holidays

• Weekly team lunch + Monday all-hands

• Professional development budget

• Fully stocked office snacks

• High ownership, low bureaucracy environment

• Direct access to founders and cross-functional team

• Real career path to AE or GTM leadership

Why This Role Matters

This isn’t just another SDR seat at a SaaS company. You're not walking into a script — you're helping invent one. The market is wide open, the demand is real, and the impact you have here will shape both your career and the future of this product.

If you’re driven by impact, obsessed with improving, and want to break into tech at a company that rewards performance over pedigree — we’d love to meet you.

Curious?
Apply confidentially — we’ll share more once we’re aligned on fit.
