Principal Software Engineer

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 world.

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.

Roles and Responsibilities :

• Design and build a high-performance, fault-tolerant pricing engine from the ground up
• 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 using advanced techniques like:
  • Zero-copy data paths
  • Lock-free data structures
  • Sophisticated fault tolerance and replication strategies
• Partner with engineers and stakeholders to shape the future of airline retailing technology
• Spend the majority of your time hands-on, tackling the hardest technical problems

Ideal Candidate :

• Expert-level programming skills in C/C++, Rust, Go, or Python, with strong fundamentals in algorithms, data structures, and systems design
• Deep understanding of Linux systems, performance, and resource management
• Proven experience building and operating fault-tolerant distributed systems at scale
• Strong problem-solver who thrives in complex, ambiguous environments and takes a data-driven, scientific approach
• Comfortable working across the stack—from low-level systems to distributed architecture and APIs
• Highly self-driven and autonomous, with the ability to proactively identify and solve problems
• Excellent written communication and collaboration skills in a remote, async environment
• Thoughtful user of AI-assisted development tools to enhance productivity while maintaining high standards of quality.

Bonus Points

• Experience in airline pricing, distribution, or ATPCO data
• Background in building high-throughput, low-latency data platforms

The Impact You’ll Have

Your work will directly influence how airlines worldwide price, distribute, and optimize their offerings—unlocking new capabilities in airline retailing and shaping the future of the industry.
