Looking to redefine how the airline industry prices and sells products at a global scale? This is not just another engineering role—this is your opportunity to architect and build a next-generation pricing engine that will power airline retailing across the globe.

At ATPCO, you’ll join a newly formed Pricing Platform Team (est. 2024) with a bold mission: to create a highly scalable, cost-efficient, and intelligent pricing platform capable of managing 200M+ fares across 160+ countries. This platform will shape how airlines distribute and optimize their products in real time.

As a Principal Software Engineer, you won’t just contribute—you’ll lead from the front, solving some of the hardest technical challenges in distributed systems, performance engineering, and large-scale data processing.

Want to redefine how the airline industry prices and sells products at global scale? This role is your chance to shape and extend the pricing engine that powers airline retailing around the world.

You’ll join ATPCO’s Pricing Platform Team, formed in 2024 to own a highly scalable, cost-efficient, and intelligent pricing platform that manages 200M+ fares across 160+ countries.

The engine is built and running; the mission now is to evolve it to support new use cases and shape how airlines distribute and optimize their products in real time.

As a Principal Software Engineer, you’ll lead from the front. You’ll set technical direction on some of the hardest problems in distributed systems, performance engineering, and large-scale data processing, and you’ll spend most of your time building.

• Extend and evolve our high-performance, fault-tolerant pricing engine to support new use cases
• Shape the platform’s architecture and drive key technical decisions with the team
• Solve complex challenges in distributed systems, scalability, and reliability
• Work across the stack, from low-level system interactions to distributed algorithms and APIs
• Optimize for extreme performance. At 200M+ fares, shaving milliseconds off latency and fractions of a cent off cost adds up fast. Techniques in play include:
  Zero-copy data paths Lock-free data structures Sophisticated fault tolerance and replication strategies Get deep in the existing engine’s codebase and design, so enhancements build on what’s already there Partner with engineers,…
