Position

Ancillaries engineers are responsible for automation and generation of the main revenue stream for the company. Our services obtain availability of extras services like seats, bags, priority boarding, show it to customers and fulfill the order. While providing a unified interface to the rest of the teams in the company, we hide complexity of 100+ different providers under a single application. Our customers rely on us that their baggage is bought, a window seat is selected, and spaghetti in the air is ordered.

We understand the codebase is always changing and therefore enforce clean code, code reviews, and automated testing. As we deploy multiple times per day, QA testing, real-time monitoring, and alerting is an inevitable part of our release process. We often refactor parts of code/product that are slowing development down but also focus on being able to deliver new features - to be innovative and deliver value to our customers. Within the team, we try to spread knowledge and collaboratively work on top priorities to avoid hero syndrome - preventing bus factor.
