What tasks await you

Development and optimization of the flight ticket search engine You will work on the core of the search system – a service that aggregates data from dozens of airlines and OTAs, processes millions of requests per day, and provides users with relevant results. Tasks include optimizing caching and filtering of offers, as well as integrating new data suppliers. You will tackle challenges related to high load and system response speed requirements.

Monitoring and improving service stability You will be responsible for the health check of critical services, setting up alerting, and handling incidents. This includes analyzing logs, metrics, and traces to identify bottlenecks, participating in on-call duties, and conducting postmortems of production incidents. The goal is to minimize downtime and ensure a seamless experience for users even during peak loads in the holiday season.

Participation in the technical development of the team You will conduct code reviews for colleagues, participate in architectural discussions, and share experience with the team. This may include mentoring interns, writing technical documentation, conducting internal meetups, or researching new technologies that can improve our product.
