We are looking for a Senior Backend Engineer with strong experience in advanced data engineering, including high-performance data processing, building scalable services, AI/ML pipelines, and deployment in high-availability production environments. The role requires hands-on experience with TypeScript, and the work will have a direct impact on the security of real-world systems at enterprise scale. This is not a typical CRUD backend role. We are solving complex, data-heavy, performance-sensitive engineering challenges.

Responsibilities

Design and develop scalable, high-availability backend services using Node.js and TypeScript, with a strong emphasis on reliability and production readiness

Participate in technical discussions and support delivery lifecycle

Work with PostgreSQL and event streaming/messaging systems, handling both structured and unstructured data

Maintain CI/CD pipelines and actively contribute to agile processes

Optimize and maintain data models (PostgreSQL, MySQL)

Participate in code reviews and mentor junior developers

Requirements

5+ years of hands-on experience building and owning complex backend systems in production

Strong backend engineering experience (Node.js/TypeScript - primary, Python - advantage), building high-scale backend services (beyond simple CRUD APIs)

Strong understanding of algorithms and data structures, with the ability to write efficient and optimized backend code

Deep understanding of scalable, distributed backend architectures, asynchronous and event-driven systems, and performance optimization, including Node.js frameworks

Proven experience with cloud infrastructure (AWS/GCP/Azure), deploying cloud-native services, and managing CI/CD pipelines with Docker and Kubernetes

Experience designing and optimizing high-volume data processing systems and working with large-scale datasets in production

Highly independent and proactive, with strong problem-solving and analytical skills, while being a collaborative team player with a strong sense of ownership for the end-to-end delivery of complex projects

Advantage

Experience in cybersecurity or security-focused products and environments

Experience with microservices architecture, Kubernetes, and SaaS development
