Job Description


We are looking for an experienced Java technologist who will work directly with development teams and will oversee the architecture and design of our Java products and services.


You will be responsible for:

• providing architectural direction to the development teams as well as driving and sharing best design practices and setting coding standards;
• ensuring a healthy level of technical stack consistency across the portfolio of our applications;
• analyzing impact of new business requirements on existing systems, architecture and performance;
• making solution recommendations to the business and designing communication interfaces;
• driving effective technical collaboration within and across the development teams as well as coordinating important decisions with other groups involved in product development;
• proposing and evaluating improvement ideas to achieve outstanding performance, maintainability, operability and reliability of our systems

Team Overview:

Our team owns a number of real-time, highly scalable systems built in different technologies. The core of our platform – IntelliSell and IntelliSell Cache – are written in C++, but several other applications such as Shopping Cache Management System, Merchandising Services and Pricing Domain Controller are built in Java.
Our team is made up of experts from various business domains – shopping, pricing, customer record and fulfillment. The teams are organized into 13 scrum teams (4-5 Developers and 1-2 QAs each), 6 Product Owners, and Scrum Masters.


Our products:


• Intellisell – an orchestrator application for all Air Shopping systems. It implements many processing flows (high level services) by making calls to several data sources (low level services).

Intellisell is highly customizable – with various configurations that can be applied per customer, market, date, etc. It consists of a web-based rule management UI, a web service based server, an integrated controller XML Server, a series of rules engines and several service adapters.

• Intellisell Cache – an advanced, home-grown caching solution, optimized for use cases required by Intellisell. It stores each priced itinerary option that has been returned by shopping data sources. Such options can be later on independently fetched by subsequent shopping requests and combined into new shopping offers. It can work with almost any of the multitude of shopping data sources.

• Shopping Cache Management System (SCMS) – a system that monitors and reports on the accuracy of data stored in the IntellliSell Cache, and is responsible for charging of the Cache.

• Ancillary Services – the backend application that provides airlines, travel agencies and individual customers a wide range of ancillary product options to offer, order and shop for. Ancillaries are flight elements like baggage, selected seats, additional on-board services, etc.

• Merchandising Services – an application that provides data about Branded Fares to Shopping and Pricing.

• Pricing Domain Controller (PDC) – application responsible for authorization, validation, and routing of requests sent to Pricing systems. It is capable of performing message format transformations, content-based routing, and advanced error handling.
