Job summary

Harmonic Security is seeking a Backend Engineer to sit inside Customer Engineering, serving as the technical backbone for how we support and delight customers daily. You’ll triage bugs, fix issues, and build tooling and automation across core apps, identity providers, and data security platforms from day one.

You will partner with customers and stakeholders to decide on patches, tools, or process changes, while pushing for automation to reduce manual work and improve reliability.

Qualifications

• 5+ years of professional software engineering experience building backend services and distributed systems in the Java ecosystem (Java, Spring Boot, Maven).
• 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.

Responsibilities

• Triage, diagnose, and fix customer‑reported bugs across our backend services.
• Deliver smallish customer‑driven requests and improvements, keeping a lightweight roadmap of your own.
• Build tooling and automation that let customers and internal teams self‑serve answers, cutting down repeat questions that would otherwise need an engineer.
• Dig into microservices, event‑driven pipelines, and integrations with identity providers and data security platforms to find and resolve root causes, not just symptoms.
• Work directly with customers and internal stakeholders to understand what's actually blocking them, then decide whether the right fix is a patch, a tool, or a process change.
• Instrument and monitor the systems customers depend on so recurring issues get surfaced and fixed before they pile up.
• Look for moments to delight, not just resolve: a workflow that could be smoother, a report that could be automatic.
• Track how much of the customer experience is still manual, and systematically drive that down through automation and fixes.
• Help define what “good” looks like for this function – process, tooling, and metrics – since you're building it from scratch
