ATPCO is the world's primary source for air fare content, holding over 200 million fares across 160 countries. The Principal Software Engineer will lead the development of a next-generation pricing engine that powers airline retailing globally, tackling complex technical challenges in distributed systems and performance engineering.
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
Requirements:
- 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
- Experience in airline pricing, distribution, or ATPCO data
- Background in building high-throughput, low-latency data platforms
