The posting
AI is being run everywhere, by humans and agents. Harmonic Security governs all of it. The AI Governance and Control (AIGC) platform understands user / agent intent and data context in real time, giving security teams visibility and control across every tool and workflow so companies can move faster with AI while minimizing risk.
We operate in one of the fastest-moving spaces in tech: the emerging intersection of AI and cybersecurity. It's a market still being defined, and we're among the first to build natively for it - protecting sensitive data in real time, at the endpoint, with minimal friction for the teams using it. Enterprises get full visibility and control. Their people get to innovate without guardrails slowing them down.
Named to the Rising in Cyber 2026 list, Harmonic is gaining serious recognition and serious traction. We're led by deep cybersecurity expertise and backed by investors who know the space: N47, Ten Eleven Ventures, and In-Q-Tel.
As AI adoption inside the enterprise accelerates, the ability to safely observe, control, and enforce policy in real time isn't a nice-to-have. It's mission-critical infrastructure. That's what we build.
HOW WE WORK: AI-FIRST BY DESIGN
Harmonic exists to help enterprises adopt AI safely and at scale. We hold ourselves to that same standard. Everyone here actively leverages AI tools to perform their best work, from deep research and writing to building robust processes and automating complex workflows. We expect every new hire to bring a genuine curiosity for AI and a commitment to using it to work smarter, faster, and with greater creativity.
For some, this involves tinkering and remaining open to emerging tools; for others, it means architecting entirely new systems with AI at the core. We will be transparent about expectations for every role and provide the tools and support needed for you to thrive.
ABOUT THE TEAM
Our Product Delivery team is the engine that turns vision into impact. We ship early and often, getting valuable features into the hands of customers quickly and iterating from there. We work in the open by default, sharing progress and ideas, and we trust each other to own outcomes. We’re a small but mighty crew where every person plays a critical role and we’re committed to using AI to work smarter and faster.
ABOUT THE ROLE
You will join an early, still-forming team of Deployment Engineers, where you have an opportunity to help define how we operate. You will onboard customers, provide day to day customer support and work through deployment problems.
This is a hands-on, individual-contributor role with direct customer impact. You will manage technically difficult customer issues that require both an inquisitive mind and a desire to provide and excellent customer experience.
WHAT YOU’LL DO
- When something breaks, you pull the logs, HAR files and configs, write a clean root cause analysis, and hand engineering a sharp escalation.
- Provide technical support during onboarding, acting as a trusted technical enablement partner to our customers.
- You find opportunities to continuously improve and strengthen the deployment experience for our customers.
- You will maintain internal guides and customer-facing documentation.
- Beyond deployment support, you feed field findings into the product roadmap and partner with Customer Success, Solutions Architecture, QA and beyond to give our customers a first class experience.
WHAT YOU BRING
- Hands-on experience deploying and supporting enterprise security or endpoint products in customer environments.
- Familiarity with MDM platforms (Intune, Jamf or similar), browser extension rollout, SSO/identity configuration and network or endpoint setup.
- You are happy working in a multi-OS environment (Windows, Linux, macOS).
- A track record of strong customer-facing communication, the kind where you coordinate through an issue, gather the right evidence, and close it cleanly.
- Operational discipline: you turn one-off fixes into tracked, documented process so nobody has to firefight the same problem twice.
- Some ability to read or write code is a bonus, but the core of this role is technical troubleshooting and customer excellence, not shipping features.
YOU MIGHT BE A FIT IF YOU
- You should be comfortable with getting direct customer feedback and thrive in a fast-moving team where your work ships into the product, not into a backlog.
- Engineers from AI-native startups, analytics or data-insight platforms, or security and governance SaaS companies.
- We want someone inquisitive and proactive who automates the repeat work, fixes the root cause, and makes life better for both the customer and their colleagues.
- Ownership here isn't a buzzword: you have it, and we expect you to use it. If you have an AI-first mindset, and a habit of looking for patterns you can automate away, it will set you apart.
