That’s why we work tirelessly to make your experience of planning & booking flights, hotels and trips as seamless as possible.

About the Job:

We’re looking for a seasoned Senior Backend Engineer to join our Flights OTA team at Wego. You’ll be part of the Flights Booking team, a key subteam within the Flights OTA group, responsible for the end-to-end booking experience — from selecting flight offers to completing reservations.

While the broader Flights OTA team also works on areas like fare display and offer integration, this role is mainly focused on the booking domain, ensuring users enjoy a seamless and reliable checkout experience.

Key Responsibilities

● Design, develop, and maintain scalable backend services and APIs.

● Participate in system architecture discussions to design efficient, maintainable, and future-proof services.

● Write clean, maintainable, and efficient code while adhering to industry best practices and internal standards.

● Collaborate with Product, UX, and Data teams to understand requirements and deliver effective technical solutions across the entire customer journey.

● Improve code quality by implementing unit tests, automation, and conducting thorough code reviews.

● Optimize backend systems for performance, scalability, and reliability to handle the demands of a global customer base.

● Debug and resolve production issues quickly to minimize the impact on users and ensure high availability.

● Stay current with emerging technologies and propose innovative solutions to enhance systems and processes.

● Create and maintain documentation such as RFC’s to improve communication across the organization.

Technical Qualifications:

● 5+ years of experience in backend software engineering, including hands-on coding and system design.

● Proficiency in Java or a similar backend programming language.

● Experience with cloud platforms (e.g., AWS, GCP, Azure) and container technologies (e.g., Docker, Kubernetes).

● Strong knowledge of relational databases (e.g., PostgreSQL, MySQL) and database optimization techniques.

● Familiarity with caching technologies (e.g., Redis, Memcached) to optimize system performance.

● Strong understanding of system architecture, scalability, and reliability best practices.

● Experience with CI/CD practices and automated pipelines.

● Solid troubleshooting and debugging skills for production systems.

● Familiarity with monitoring and observability tools (e.g., Datadog, Prometheus, Grafana).

In addition, our ideal candidates are expected to:

● Maintain rigorous standards for both personal and team performance, encompassing engineering and communication disciplines.

● Proactively identify areas for enhancement across all operational domains.

● Possess advanced proficiency in both written and spoken English to facilitate effective collaboration with international teams and departments.

● Effectively manage complex and extensive project scopes, focusing on comprehensive product delivery rather than isolated feature implementation.

● Demonstrate robust ownership of product development and issue resolution, coupled with the ability to self-resolve obstacles through proactive communication.

● Integrate artificial intelligence into daily workflows and exhibit efficiency in leveraging its capabilities.
