About Harmonic Security

Harmonic Security lets teams adopt AI tools safely by protecting sensitive data in real time with minimal effort. It gives enterprises full control and stops leaks so that their teams can innovate confidently.

We are led by cybersecurity experts and backed by top investors including N47, Ten Eleven Ventures, and In-Q-Tel. 

We’ve gained early traction and product-market fit with a world-class team, and we’re now focused on laying the foundation for a truly iconic global brand. This is your opportunity to join us early and shape not just a brand, but a category.

About the Team

Our Sales team is in the early stages of building something extraordinary. We’re a tight-knit, ambitious group laying the groundwork for how Harmonic goes to market. Every rep plays a critical role in building pipeline, landing new logos, and shaping how Harmonic goes to market. We’re builders as much as sellers — refining the playbook, collaborating across teams, and creating repeatable success.

About the Role

We’re looking for a Sales Representative to drive growth across the East or Central U.S. You’ll own the full sales cycle: identifying prospects, building relationships, running demos, negotiating deals, and closing new business. This is an opportunity to join a category-defining company at the ground floor — building your territory while influencing how we sell as a team.

What You’ll Do 

• Own the full sales cycle: prospect, qualify, demo, negotiate, and close
• Build and manage pipeline across assigned territory
• Develop account strategies in partnership with leadership
• Drive outbound prospecting and convert inbound leads
• Deliver compelling, tailored presentations and product demos
• Collaborate with Marketing, Product, and Customer Success for alignment and feedback
• Represent Harmonic at customer meetings and industry events
• Contribute to shaping our sales playbook and scaling best practices

What Success Looks Like 

• New customers in your territory are signing and expanding with Harmonic
• Pipeline is healthy, with a balanced mix of outbound and inbound opportunities
• Deals are moving efficiently through the funnel with strong win rates
• You’re a trusted partner, surfacing market insights and helping refine our approach
• Sales processes and tools are more repeatable and effective because of your input

What you Bring 

• 4-8+ years of quota-carrying B2B SaaS sales experience (cybersecurity a plus)
• Track record of hitting or exceeding quota in a closing role
• Comfort with outbound prospecting and building a territory from scratch
• Strong communication, storytelling, and relationship-building skills
• Ability to manage complex sales cycles with technical and business stakeholders
• Organized, resourceful, and thrives in a startup/Series A environment

You Might Be a Fit if You…

• Love the challenge of opening new markets and winning early customers
• Thrive in fast-moving, ambiguous environments where you help create structure
• Enjoy collaborating with Marketing and Product to refine messaging and positioning
• See sales as both art and science — and you’re excited to shape the playbook
• Believe AI and security will define the next decade of enterprise software
