Backend Software Engineer – Node.js - (26000016)

About the Job

As a Backend Software Engineer at Edgehawk Security, you will be a lead contributor to our api gateway, the central nervous system of our security infrastructure. This role is focused on building high-scale, resilient backend services that manage and process critical security data in real-time. You will work at the intersection of cybersecurity and distributed systems, ensuring our controller can handle high-throughput traffic and complex data orchestration across high-performance databases and security protocols.

What You’ll Do

Architect Core Services: Develop and maintain domain-specific services using a modular, service-oriented architecture.
Master Data Orchestration: Manage complex data flows across a diverse stack, including MongoDB for persistence, Kafka for messaging, Redis for high-speed caching, and ClickHouse for massive-scale analytical data.
Secure the Gateway: Manage identity and access control by integrating and extending Keycloak for secure, centralized authentication.
Optimize Performance: Implement advanced patterns like data chunking and asynchronous processing to handle large-scale security configurations and time-series metrics in InfluxDB.
Own the Lifecycle: Manage the full development lifecycle—from writing unit tests with Jest to containerizing applications with Docker and deploying via Kubernetes.

What We Are Looking For

Experience (Required):
3+ years of professional backend development experience, with hands-on responsibility for building and maintaining production systems.
Node.js Ecosystem (Advantage):
Strong experience with Node.js and its ecosystem, including designing scalable, modular backend services.
Databases & Analytics (Advantage):
Experience working with a combination of:
NoSQL databases such as MongoDB
Time-series databases like InfluxDB
High-performance analytical databases, particularly ClickHouse
Networking & Security (Advantage):
Familiarity with modern authentication and authorization solutions such as Keycloak, OIDC, or SAML, and a solid understanding of securing RESTful APIs.
Infrastructure & Distributed Systems (Advantage):
Experience with:
Redis for caching or state management
Kafka or similar systems for event-driven architectures
Running services in Linux-based, containerized environments
Engineering Practices (Advantage):
A strong focus on code quality, including experience with Jest, test-first or test-driven development, and writing clean, maintainable, and scalable code.

Why Join Edgehawk Security?

High-Impact Work: You aren't just building another CRUD app; you are building tools that protect critical infrastructure from sophisticated cyber threats.
Advanced Tech Stack: Work with a cutting-edge, containerized environment using ClickHouse, Kafka, and Keycloak to solve the industry's toughest data and security challenges.
Ownership & Autonomy: We value engineers who take initiative. You’ll have the freedom to influence the architecture of the controller-rest-api and see your changes deployed directly to the front lines of security.
Growth Culture: Join a team where technical excellence is the standard and where "modular design" and "intellectual curiosity" are the primary drivers of our success.
