• Mentorship: Mentor mid-level & juniors engineers, fostering a culture of code quality, testing excellence, and creative problem-solving.
• Hands-on Development: Remain hands-on in the code (70/30 split), writing high-performance, maintainable production code.
• Innovation: Research and integrate new technologies (databases, messaging systems, frameworks) to optimize platform performance and scalability.
   

Requirements

• Modern Web Ecosystem: Familiarity with the broader stack, including TypeScript, React, and GraphQL.
• Education: Bachelor's degree in Computer Science, Software Engineering, or a related field (or equivalent experience).
• Soft Skills:
  • Excellent verbal and written communication skills in English.
  • A collaborative, team-oriented mindset with the ability to navigate diverse stakeholder requirements.
