  • champion code excellence by implementing best practices in code testing, maintaining quality standards, and providing insightful code reviews
  • innovate and automate by investigating emerging technologies and AI trends to reduce manual overhead and accelerate team velocity

Requirements

  • English proficiency at B2 level or above, with the ability to articulate complex technical concepts to diverse stakeholders
  • a strong sense of ownership over your work and a commitment to continuous learning and knowledge sharing
