Job Description
At Lumifi Cyber, we develop robust, secure systems that power our cybersecurity solutions. We’re seeking a mid-level Backend Developer who will focus on server-side logic using modern JavaScript and TypeScript in a Node.js environment. You’ll be working with PrismaJS for data persistence (PostgreSQL), building APIs and integrations in Next.js (server-side only), and developing microservices to automate various backend functions. You’ll collaborate closely with other developers, ensuring efficient and reliable solutions that reinforce our overall security posture.

Duties and Responsibilities

Develop and maintain scalable backend systems using modern programming languages, with a preference for JavaScript (ESNext) and TypeScript.
Design and optimize microservices architecture to support automation and integrations.
Implement API endpoints, preferably using frameworks such as Next.js (front-end UI work is not required but familiarity is a plus).
Manage data storage and retrieval, ideally with ORM tools like PrismaJS and databases such as PostgreSQL.
Write and maintain comprehensive technical documentation for backend features and processes.
Debug, troubleshoot, and optimize backend systems for performance, reliability, and security.
Utilize testing frameworks (e.g., Jest) in a test-driven development (TDD) environment to ensure code quality.
Collaborate effectively with cross-functional teams to support seamless integration and deployment processes.
Stay informed of industry best practices and emerging backend technologies to drive continuous improvement.

Required Skills/Abilities

2–3 years of experience with backend development in a modern programming environment.
Strong proficiency in server-side development, ideally using Node.js or similar technologies.
Experience building and maintaining API-driven services, with a preference for Next.js.
Hands-on experience with ORM tools and relational databases (e.g., PrismaJS, PostgreSQL).
Familiarity with microservices architecture and version control systems like Git.
Comfortable working in a test-driven development environment with tools such as Jest (Mocha/Chai also acceptable).
Strong analytical and problem-solving skills with the ability to tackle complex challenges.
Effective communication skills, both written and verbal, to document and share knowledge.
Ability to adapt and thrive in a fast-paced, evolving technical landscape.
Proven ability to problem-solve and think critically in a fast-paced environment.
