What we do: 

Zefr is the leader in AI-powered content classifications for brands and advertisers. Zefr’s platform is purpose built for multi-modal content understanding on open platforms like YouTube, TikTok, Meta and Snap, with pre-bid activation and verification solutions. Our products safeguard media and AI investments, while maximizing performance and efficacy on those channels. Headquartered in Los Angeles with global offices across New York, Chicago, London, Toronto, Singapore, and more, Zefr is redefining what trust and transparency means for social media in the age of AI.

We are seeking a driven Sales Development Representative to join our Targeting team. You’ll be on the front lines of Zefr’s growth — identifying new business opportunities, building qualified pipelines, and helping agency and brand partners discover how Zefr drives performance and responsibility on YouTube and beyond.

You’ll work closely with Account Executives (AEs), Account Managers (AMs), and Marketing to target priority agencies and brands, conduct prospecting outreach, and convert leads into meetings that fuel revenue. This is a foundational role with a defined growth path toward Account Executive.

Here’s what you’ll get to do:

• Prospect and qualify inbound and outbound leads within assigned agency and brand territories

• Partner with AEs to research, target, and develop outreach strategies across independent, and potentially hold’co accounts

• Craft personalized outreach using email, phone, and LinkedIn to secure discovery meetings

• Leverage Salesforce and other tools to track activity, pipeline status, and conversion metrics

• Collaborate cross-functionally with Marketing and Revenue Ops to refine lead scoring, campaign follow-up, and performance tracking

• Maintain expert understanding of Zefr’s contextual data products, YouTube solutions, and brand suitability framework

• Contribute to weekly pipeline reviews and provide feedback on what messaging, industries, or formats are resonating

Here’s what we’re looking for:

• 2–3 years of experience in digital advertising, SaaS or media sales

• Familiarity with CRM systems (Salesforce, HubSpot) and outreach tools (Salesloft, Outreach, Apollo, etc.)

• Curiosity about digital media, YouTube, AI, and brand safety

• Excellent communication, writing, and organizational skills

• Comfort working in a fast-paced, data-driven, and collaborative environment

• Self-starter mindset with resilience, enthusiasm, and accountability

• Familiarity with the adtech ecosystem (DSPs, SSPs, CTV, social, programmatic) is a plus

• Familiarity with digital tools and technology platforms including Salesforce is a plus

• Proficiency in Microsoft Office Suite

• BA/BS from a 4-year university or equivalent experience

Benefits (for US based employees):

• Flexible PTO

• Medical, dental, and vision insurance with FSA options

• Company-paid life insurance

• Paid parental leave

• 401(k) with company match

• Professional development opportunities

• 13+ paid holidays off

• Flexible hybrid work schedule

• “Summer Fridays” (shorter work days on select Fridays during the summertime)

• In-office lunches and lots of free food

• Optional in-person and virtual events (we like to celebrate!)

Compensation (for US based employees):

The annual on-target earnings for this position is between $70,000 and $90,000.  Within the range, individual pay is determined by factors such as job-related skills, experience, and relevant education or training. If your compensation expectations fall outside of this range, it may still be worth having a conversation.
