• Own outbound like a product. From idea to reply to booked call - you’ll shape what we say, who we say it to, and how it evolves over time.
• Collaborate with an outbound infrastructure agency. You’ll work with a partner who manages warm-up, deliverability, rotation, and 100+ inboxes. No babysitting inboxes, just smart execution.
• Be the hypothesis machine. Interview Solution Architects, dig into case studies, and extract insights that become campaign angles. Messaging that earns attention, not just opens.
• Design and launch sequences. Write and iterate campaigns with clear angles and ICP fit. Test. Learn. Refine.
• Tier, segment, prioritize. Structure audiences into Tier 1/2/3 groups and adjust channels, content depth, and personalization accordingly.
• Build and enrich lead lists. Use tools like Apollo, Clay, and Sales Nav to build and validate lists. (We’re also exploring how AI agents can streamline this - you’ll help shape that future.)
• Amplify through social selling. Work closely with our technical experts and marketing team to align outbound messaging with our growing LinkedIn presence. Great posts = great campaigns.
• Run with high autonomy. You’ll have space to lead outbound and to shape our growth.
  
  🎯 What We Expect
   
• 5+ years in outbound, sales strategy, or growth roles, ideally in B2B tech or SaaS.
• Strong analytical and messaging skills. You’re as comfortable writing a punchy cold email as you are segmenting by ICP tiers.
• Hands-on experience with Apollo, Clay, Sales Navigator, and similar tools.
• Curiosity and initiative, you’re not waiting for someone to tell you what to try next.
• Comfortable working with prompts, AI tools, and automation.

• Bonus if you’ve ever structured outbound around hypothesis-driven messaging.
