## Job description

About Nightfall: Nightfall is the AI-native, unified data loss prevention and insider risk management platform that protects sensitive data across SaaS apps, GenAI tools, email, endpoint devices, and more. Hundreds of customers, spanning AI innovators to top 10 banks, trust Nightfall to detect and stop data exfiltration at scale. Nightfall enables organizations to innovate freely without the risks of losing intellectual property or exposing customer data. Our agentic platform helps security teams regain their time by putting data loss prevention on autopilot. With automatic remediation, security violations can be resolved automatically before they become incidents, and end-users can be automatically trained and coached in the moment to self-heal violations that they introduce. Nightfall is backed by leading VC firms including Bain Capital Ventures (Enrique Salem - former CEO of Symantec), Venrock (early investors in Cloudflare), WestBridge Capital, Pear VC (early investors in Dropbox and Doordash), and a cadre of cybersecurity leaders including Frederic Kerrest (founder of Okta), Maynard Webb (former COO of eBay), Ryan Carlson (President of Chainguard), Kevin Mandia (founder of Mandiant), and many others. About the role: As a Sales Development Representative (SDR) at Nightfall AI, you'll be on the front lines of our go-to-market efforts — identifying and qualifying new business opportunities and driving pipeline growth. You'll be the first point of contact for many prospective customers, communicating Nightfall's value as AI-native data loss prevention for the modern enterprise.

## Responsibilities

- Generate pipeline through a 70/30 mix of outbound prospecting (email, calls, social) and inbound lead qualification
- Communicate Nightfall's value and use cases to security, compliance, and engineering stakeholders
- Partner with Account Executives on meeting scheduling and clean lead handoffs
- Keep CRM activity accurate and up to date
- Refine outreach based on performance data and feedback

## Qualifications

- 1+ years of SDR experience — looking to build a career here, not a short-term stop
- Previous SDR experience at a SaaS or high-growth startup
- Background in cybersecurity, data security, or DLP
- Bachelor's degree or equivalent experience
- Strong written and verbal communication with both technical and non-technical audiences
- Organized, detail-oriented, and comfortable managing multiple workstreams
- Resilient, driven, and comfortable with ambiguity in a fast-paced environment
- Fluent with AI tools and quick to learn technical products
- Familiarity with Salesforce, LinkedIn Sales Navigator, HubSpot, Apollo, or similar tools

Environment Nightfall AI takes pride in being an equal-opportunity employer. We value a diverse and global talent pool and the collaboration that results from having a diverse and inclusive team. All applicants will be considered for employment without attention to race, color, religion, sex, sexual orientation, gender identity, national origin, veteran or disability status. Our hiring decisions are based exclusively on merit, qualifications, and business needs.

## Compensation

Employee compensation will be determined based on interview performance, level of experience, specialization of skills, and market rate. During the offer discussion, your recruiter will review the finalized base salary, bonus (for applicable roles), benefits & perks, and stock options as they’ll be reflected in the offer letter.

## Core Business
- **Industry**: Cybersecurity – Data Loss Prevention (DLP) & Insider Risk Management

- **Mission**: “Data protection has to work intelligently and invisibly, or it won’t work at all.” Nightfall aims to enable any company to secure sensitive data across every SaaS app, AI tool, and endpoint without disrupting workflows.

## Products & Services
- **AI-Native DLP Platform**: SaaS-based platform using 100+ AI models, LLM-based file classifiers, and computer vision to classify content with 95% accuracy. Includes data lineage tracking that traces information from source to destination.
- **API-Based SaaS Integrations**: Deploys in minutes across Microsoft 365, Google Workspace, Slack, Salesforce, Atlassian, Zendesk, Notion, and more.
- **Endpoint Agents**: Lightweight agents for macOS and Windows (deployed via MDM) that monitor data movement and enforce policies.
- **Browser Plugins**: Real-time protection for AI apps (ChatGPT, Copilot, Gemini, DeepSeek, Claude, Perplexity, etc.) – blocks sensitive data from being pasted or uploaded.
- **Shadow AI Security**: Purpose-built to prevent data leaks to generative AI tools, including both prompts and file uploads.
- **Automated Remediation**: Context-aware actions such as blocking, redacting, revoking access, quarantining, or encrypting data. 80% of incidents resolved via automation or self-remediation.

## Market Standing
- **Total Funding**: $60.3M (as of CB Insights)
- **Latest Round**: $40M Series B (raised ~4 years ago)
- **Notable Investors**: Venrock, Bain Capital Ventures. Also backed by a “cadre of CEOs, investors, professional athletes, and experts across infosec, AI, and enterprise software.”

## Competitive Advantages
- **AI-Native Accuracy**: 95% out-of-the-box precision eliminates weeks of tuning and reduces false positives.
- **Data Lineage**: Tracks data as it moves, transforms, or is copied – catches exfiltration that regex-based tools miss.
- **Rapid Deployment**: API-based integrations in hours; no network architecture changes; zero productivity disruption.
- **Continuous Learning**: Models improve automatically, reducing false positives over time.
- **Vendor Consolidation**: Replaces multiple legacy tools (regex DLP, CASB, endpoint DLP, etc.) with a single platform.

## Strategic Focus
- **Securing AI Adoption**: Blocking data leaks to generative AI tools (ChatGPT, Copilot, etc.) while enabling safe innovation.
- **Expanding MCP Visibility**: Monitoring data movement across AI agents, MCP servers, and new attack surfaces.
- **Reducing Operational Overhead**: Using automation and employee self-remediation (80% of incidents) to lighten security team workload.
