Job Description

N-iX is looking for a Senior Python Full-Stack Engineer (React) 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 a full-stack 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.

  • Build and evolve frontend applications using React
  • 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 experience in Software Engineering
  • Strong expertise with Python (backend development)
  • Solid experience with React and modern frontend development
  • Experience building full-stack applications end-to-end
  • Good understanding of RESTful APIs and client-server architecture
  • Familiarity with Agile development methodologies
  • Experience working in a team environment with shared ownership
  • Comfortable using AI tools in daily development (e.g., coding assistants, test generation, debugging, documentation support)

What 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
