You will:

• Work in a cross-functional Agile team, participating in all development phases from planning to production.
• Provide technical mentorship, conduct code reviews, and engage in architectural discussions.
• Continuously improve systems for scalability, performance, and resilience.
• Collaborate with stakeholders to shape product direction and make architecture decisions.

• Solid understanding of computer science fundamentals (data structures, algorithms, system design)
• Passion for clean, maintainable code and modern practices (CI/CD, TDD, DevOps)
• Strong communication and collaboration skills
• A drive to learn and improve — both yourself and the systems you build
  

As a Team, We love to:

• Build reliable, scalable systems that empower millions of travellers
• Keep our codebase clean and architecture elegant
• Learn from each other, share knowledge, and grow together
• Celebrate wins, reflect on misses, and always aim higher
