AI SDR Engineer

About Us

Endor Labs is building the Application Security platform for the software development revolution. Modern software is complex and dependency-rich, making it increasingly difficult to pinpoint the risks that truly matter. Endor Labs solves this challenge by building a call graph of your entire software estate—enabling teams to clearly identify, prioritize, and fix critical risks faster. 

Trusted by companies that are one or one hundred years old, Endor Labs secures code whether it was written by humans or AI, and whether it's 40-year old C++ code or cutting edge Bazel Monorepos. Endor Labs was founded by serial entrepreneurs Varun Badhwar and Dimitri Stiliadis, and is backed by leading VC firms such as Dell Technology Capital, Lightspeed, and Sierra Ventures.

Impact of this Role

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.

How You’ll Make an Impact

You’ll own the downstream layer of Endor’s GTM engine — where intelligence becomes action, and automation drives pipeline.

Agent Design and Deployment

• 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.

Orchestration and Activation

• 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.

Performance Optimization

• 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.

SDR Enablement and Collaboration

• 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.

Core KPIs

• Meetings and Pipeline Created via AI-assisted or agent-led outreach
• Lead-to-Meeting Conversion Rate for agent-handled leads
• SDR Productivity Uplift (meetings per rep, time saved per task)
• Escalation Rate and Handoff Quality (AI → human)
• Agent Reliability (accuracy, compliance, tone adherence)

What You Bring to the Table

You combine the instincts of an SDR with the mindset of an engineer — fluent in GTM systems, prompt logic, and automation strategy.

• 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

You Might Be a Fit If You

• 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 Makes Us... Us

• Go to extraordinary lengths to distinguish ourselves through world-class work.
• Prioritize quality over speed, and speed over scope.
• Desire to work with deeply kind, mission-driven people.
• Strive to make the complex simple.
• Use first principles to debate ideas, test assumptions, and make decisions.
• Seek the truth by putting data above opinions.
• Assume good intent and give tactical feedback to help each other get better.
• Hold no ego—when our customers win, we all win.

What We Offer You

• 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 (we want you here for the long-haul!)
• Opportunities for co-working and team meetups to foster collaboration.
• A dog-friendly office environment for those who love to bring their fur babies along.
