Job summary

Casco in San Francisco is seeking a Sales Development Representative to turn founder-led momentum into a repeatable outbound engine. You’ll start conversations with AppSec leaders and CISOs who know annual pentests and noisy security scanners cannot keep up with how quickly modern teams ship software.

Your job is to make the problem urgent, earn the right to a deeper conversation, and create qualified pipeline for Casco’s autonomous security testing platform.

Qualifications

• At least one year of outbound SDR or BDR experience in B2B software, with evidence that you can consistently create qualified meetings.
• Strong writing and research skills. You can find a real reason to contact an account and explain it without corporate filler.
• Comfort on the phone. You can open a cold conversation, ask a useful question, listen, and earn a next step.
• The curiosity to learn application security, pentesting, vulnerabilities, cloud environments, APIs, and how technical buyers evaluate new security products.
• Good judgment about quality. You would rather create the right meeting than hit a vanity activity number.
• Resilience and follow-through. You can handle rejection, keep your standards high, and stay organized across a large account set.
• Startup readiness. You are comfortable testing ideas, working without a finished playbook, and making your own progress visible.
• The ability to work in person from our San Francisco office.

Responsibilities

• Create qualified pipeline: Research target accounts, identify the right AppSec and security leaders, and turn cold accounts into real sales conversations.
• Write outbound that sounds human: Build sharp, account-specific messaging across email, phone, LinkedIn, and other channels instead of hiding behind generic sequences.
• Learn the security problem: Understand how companies buy pentests today, where point-in-time testing falls short, and why continuous autonomous testing matters.
• Qualify for substance: Find a credible security problem, relevant use case, buying context, and concrete next step before handing an opportunity to an Account Executive.
• Attend security events: Meet prospects in-person, start conversations, and follow up quickly to create pipeline.
• Build the playbook: Test personas, industries, hooks, objections, and channels, then document what works for repeatability.
• Keep the CRM honest: Record source, account, persona, meeting outcome, and next steps to improve pipeline quality.
• Close the feedback loop: Share what prospects say with founders, sales, engineering, and security to sharpen the product and story.
