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.
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.
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.
We’re looking for a Backend Engineer who has an appreciation for all things security and system interconnectivity. This is a very hands-on technical role where you will be responsible for designing, building and maintaining scalable integrations between our core applications, identity providers and data security platforms.
Own deliveries and features from start to finish
Design, build, and own backend services in a microservices-based, event-driven architecture
Implement core domain logic that drives key product workflows and system behavior
Ingest and process high-volume usage and event data from customer-facing endpoints
Build backend services that support operational, analytics, and reporting use cases
Model, persist, and manage domain data, enabling querying, filtering, and lifecycle management
Expose well-designed APIs and webhooks consumed by customers, UIs, and external systems
Power customer-facing UI experiences by providing backend APIs for visibility, analytics, and configuration
3–5+ years of professional software engineering experience building backend services and distributed systems in the Java ecosystem (Java, Spring Boot, Maven/Gradle)
Strong understanding of event-driven architectures, asynchronous processing patterns, messaging systems, and distributed system design
Proven experience designing and maintaining RESTful APIs, web hooks, and service-to-service integrations
Comfortable operating in AWS, GCP, or Azure environments and working with modern observability tooling, logging, and monitoring platforms
A track record of delivering performant, reliable and scalable applications
Excellent collaboration and communication skills in cross-functional teams
Have experience building products in cybersecurity, identity, governance, compliance, data protection, or enterprise SaaS environments
You understand not just how to build systems, but why architectural decisions matter
You can balance scalability, reliability, maintainability, and speed of execution
You think critically about security, observability, and operational excellence from day one
Love the idea of blending software development, distributed systems and data-intensive applications
Strong familiarity with authentication and identity technologies such as OAuth, OpenID Connect (OIDC), SAML, SCIM, Entra ID (Azure AD), Okta, or other enterprise identity providers
Thrive in fast-paced startup environments where ambiguity is the norm
Enjoy shaping culture and engineering practices, not just writing code
Leverage AI tools as an engineer to help you build smarter, faster and better
