Senior Software Engineer

Role & responsibilities

• Develop clean, scalable code using C# / .NET in a microservices, cloud-native architecture (Azure/AWS).
• Design and implement high-performance travel search and booking flows (shopping, pricing, availability, ticketing).
• Integrate with GDS, NDC, LCC APIs.
• Work with flight and ancillary services including seat maps, baggage, fare families, upsell/cross-sell.
• Optimize search performance (latency, caching strategies, concurrency, rate limiting, resiliency patterns).
• Implement orchestration layers for multi-provider search aggregation and normalization of responses.
• Handle complex pricing logic (fare rules, combinability, branded fares, dynamic pricing).
• Monitor and optimize system performance, observability (logging, tracing, metrics), and reliability (SLAs/SLOs).
• Build and maintain scalable APIs (REST/SOAP), event-driven components, and asynchronous workflows.
• Ensure high availability and fault tolerance in distributed systems (circuit breakers, retries, fallbacks).

Preferred candidate profile

• 5+ years of professional experience in software development using C# / .NET and modern cloud architectures.
• 5+ years of travel experience in travel business: flight shopping, booking engines, OTA platforms, or metasearch.
• Hands-on experience integrating with GDS (Sabre, Amadeus, Travelport) and/or NDC APIs.
• Solid understanding of airline concepts: PNR, e-ticketing, fare rules, availability, schedule changes, cancellations.
• Experience with high-throughput, low-latency systems and distributed architectures.
• Experience with observability tools (e.g., OpenTelemetry, Application Insights, Grafana).
• Ability to translate business requirements (conversion, pricing accuracy, availability) into technical solutions.
