  • Ability to quickly understand complex systems, identify areas for improvement, and drive technical initiatives independently
  • Self-motivated, proactive, and comfortable working in a fast-paced environment with a high degree of ownership
  • Excellent communication skills and professional fluency in English.

 

Nice to have:

  • Professional experience with React and modern frontend development practices

  • Experience working in startup or high-growth environments
  • Familiarity with cloud-native architectures and infrastructure
  • Availability within GMT ±3 hours
