Job Description:

Endor Labs is building the next evolution of Sales Development — where human reps and AI systems operate in tandem to generate pipeline at scale. The AI SDR Engineer focuses on activation — turning intent, product usage, and firmographic signals into contextual, compliant, and commercially effective outbound sequences. This role blends SDR fluency with applied AI design — codifying outbound logic into AI workflows, ensuring every touchpoint feels human, and driving measurable pipeline lift.

Job Responsibility:

Build and maintain AI SDR agents that conduct outbound, follow-up, and qualification conversations across email, chat, and LinkedIn
Translate SDR playbooks and persona frameworks into structured prompts, logic flows, and decision trees
Define escalation paths, confidence thresholds, and handoff rules between AI agents and human SDRs
Consume and act on prioritized signals from GTM systems (Common Room, Clay, TitanX, Salesforce)
Launch personalized, multi-threaded outbound plays triggered by intent or behavioral data
Ensure CRM alignment for attribution, performance tracking, and data hygiene
A/B test prompts, response strategies, and timing logic to improve reply and meeting rates
Analyze drift, hallucination, and misclassification rates to refine model reliability
Build feedback loops between SDRs, AEs, and agents to continuously improve tone and accuracy
Partner with Enablement to train SDRs on AI-assisted workflows and escalation handling
Surface real-time insights and recommended responses within SDR tools
Maintain documentation on agent logic, behavioral parameters, and known failure modes

Requirements:

4–8 years in Sales Development, RevOps, or GTM systems roles
Proven ability to build or manage AI-driven automation workflows (e.g. Clay, LangChain, Zapier, Relevance, OpenAI API)
Deep CRM and sequencing experience (Salesforce, HubSpot, Outreach, Apollo)
Strong understanding of LLMs, prompt engineering, and agentic architectures
Solid grasp of GTM funnel logic and SDR processes — from lead scoring to meeting booked
Comfort with experimentation, data-driven iteration, and A/B testing
Exceptional communicator who can translate between technical and commercial contexts

Nice to have:

Think like an SDR but build like an engineer
See every outbound sequence as a programmable workflow
Know when to hand control to the human — and when to let AI run
Treat agent drift as a systems problem, not a messaging one
Measure success in booked meetings and pipeline lift, not vanity metrics

What we offer:

Competitive salary and comprehensive benefits package including Health, Dental, Vision and Mental Health plans
401(k) plan to support your longterm financial goals
Flexible PTO to maintain a healthy work-life balance
Opportunities for co-working and team meetups to foster collaboration
A dog-friendly office environment
