• Strategic Input: Help shape the frontend roadmap and influence the broader engineering strategy across the organization

Requirements:

• 4+ years of experience in professional software development, with at least 3 years focused on high-level Frontend engineering
• Angular Mastery: Deep expertise in Angular (v16+) including Signals, RxJS streams, and modern state management patterns
• Advanced Styling: Expert knowledge of CSS/SCSS, including layout strategies (Grid/Flexbox), transitions, and content projection for modular UI
• Python Proficiency: Strong hands-on experience with Python, specifically for building APIs, automation scripts, or backend integrations
• System Design: Familiarity with RESTful architectures, OAuth2, and JSON-based data exchange
• Academic Background: B.Sc. in Computer Science, Software Engineering, or a related technical field

Desirable:

• Visualizing Data: Experience with data visualization libraries (e.g., D3.js, Highcharts, or Cytoscape) for displaying complex network graphs
• Modern Tooling: Experience leveraging AI-assisted development tools to accelerate coding and testing
• DevOps Mindset: Practical experience with CI/CD pipelines, Docker, and containerized environments
• Security Domain: Previous experience in Cyber Security or working with low-latency distributed systems

What`s in it for you?

• Strong community: Work alongside top professionals in a friendly, open-door environment
• Growth focus: Take on large-scale projects with a global impact and expand your expertise
• Tailored learning: Boost your skills with internal events (meetups, conferences, workshops), Udemy access, language courses, and company-paid certifications
• Endless opportunities: Explore diverse domains through internal mobility, finding the best fit to gain hands-on experience with cutting-edge technologies
