N-iX is looking for a Senior Java Engineer to join a collaborative product team of around 8 engineers working on a complex, high-impact software platform.

You’ll contribute across the stack, building scalable backend services and intuitive frontend experiences, while actively using AI-powered development tools to improve productivity and code quality. The team follows Agile best practices, values clean architecture, ownership, and continuous improvement. As an engineer, you’ll help to develop the platform that serves as an enterprise next-generation endpoint protection (EPP) + endpoint detection & response (EDR) solution that runs on Windows (as well as macOS, Linux, servers, etc.). It comes as a single, unified agent designed to prevent, detect, respond, and remediate cyber threats, including malware, ransomware, fileless attacks, and advanced persistent threats — all in real time.

  • Collaborate closely with backend, frontend, and QA engineers in an Agile/Scrum environment
  • Write clean, testable, and well-documented code
  • Integrate and work with APIs, data stores, and third-party services
  • Use AI-assisted development tools (e.g., code assistants, testing tools, analysis tools) to improve delivery speed and quality
  • Support production systems and participate in troubleshooting when needed

Requirements:

  • 5+ years of extensive software engineering experience
  • Proficiency in Java
  • Proven expertise in developing large-scale distributed systems and microservices architecture, with a focus on performance, scalability, and reliability
  • Experience with cloud platforms (AWS and/or GCP) and Kubernetes (must)
  • Experience with Kafka or similar solutions
  • Excellent problem-solving skills
  • Strong communication skills and ability to articulate technical concepts and influence engineering direction across teams, departments, and stakeholders
  • Upper-intermediate level English

We offer*:

  • Flexible working format - remote, office-based or flexible
  • A competitive salary and good compensation package
  • Personalized career growth
  • Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
  • Active tech communities with regular knowledge sharing
  • Education reimbursement
  • Memorable anniversary presents
  • Corporate events and team buildings
  • Other location-specific benefits
  • not applicable for freelancers
