Nightfall AI is an AI-native, unified data loss prevention and insider risk management platform protecting sensitive data across SaaS apps, GenAI tools, email, endpoint devices, and more. The company serves hundreds of customers ranging from AI innovators to top-10 banks, backed by leading VCs including Bain Capital Ventures, Venrock, and WestBridge Capital, with advisors including Frederic Kerrest (founder of Okta), Maynard Webb (former COO of eBay), and Kevin Mandia (founder of Mandiant). As a Sales Development Representative, you will be on the front lines of go-to-market efforts, identifying and qualifying new business opportunities and driving pipeline growth. You'll be the first point of contact for prospective customers, communicating Nightfall's value as AI-native data loss prevention for the modern enterprise. Key responsibilities include generating pipeline through a 70/30 mix of outbound prospecting (email, calls, social) and inbound lead qualification; communicating Nightfall's value and use cases to security, compliance, and engineering stakeholders; partnering with Account Executives on meeting scheduling and clean lead handoffs; maintaining accurate CRM activity; and refining outreach based on performance data and feedback. You should have 1+ years of SDR experience at a SaaS or high-growth startup, with background in cybersecurity, data security, or DLP. A bachelor's degree or equivalent experience is required. You must demonstrate strong written and verbal communication with both technical and non-technical audiences, be organized and detail-oriented, and comfortable managing multiple workstreams. The ideal candidate is resilient, driven, comfortable with ambiguity in fast-paced environments, fluent with AI tools, quick to learn technical products, and familiar with Salesforce, LinkedIn Sales Navigator, HubSpot, Apollo, or similar tools.
