About The Position

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 achieved early traction and product-market fit, and we’re now entering the phase where technical credibility, customer trust, and execution in the field will define the category. This role sits at the center of that inflection point. You’ll shape how our most strategic customers experience Harmonic, influence the product roadmap through real-world insight, and build the technical field organization that helps turn early momentum into a category-defining company. About the Team You'll report to the VP GTM Strategy & Operations and work closely with product, engineering, marketing, and partner teams. This is a highly cross-functional role where you'll serve as the technical bridge between prospects evaluating our platform, customers deploying it, and partners extending our reach. You'll build and lead a world-class solution architecture team while delivering solutions that meet complex enterprise security requirements. About the Role We're looking for a rare combination: a security architecture expert who can build and lead teams, architect enterprise solutions, and serve as a trusted technical advisor to our customers' security leaders. This is a player-coach role where you'll split your time between hands-on customer engagement, team building, and technical thought leadership. If you've ever been called a "field CTO" or wished you could combine deep security expertise with the thrill of customer-facing problem solving, this role is for you.
