Senior Software Engineer – GDS, Codeshare & Interline Support (.NET)

We are seeking a seasoned Senior Software Engineer to join our travel technology team, specializing in Passenger Service Systems (PSS) and Global Distribution Systems (GDS). This is a mission-critical role where you will design, build, and maintain the backbone of our airline’s distribution and inventory systems. You will balance proactive feature development—touching reservations, ticketing, and fare distribution—with high-stakes production support. As a senior member of the team, you will act as an escalation point for live incidents, ensuring the reliability of systems that directly impact passenger travel and airline operations.

Key Responsibilities

• System Integration:

  Design and maintain robust integrations with major PSS platforms (e.g., Amadeus Altéa, Sabre, Travelport, Navitaire, Radixx) and GDS networks.

• Core Development:

  Build and support systems managing reservations, ticketing, fare calculation, inventory/availability, PNR management, and revenue accounting using .NET.

• Messaging & Protocols:

  Implement solutions using industry-standard formats including EDIFACT, Type A/B messaging, NDC, and IATA standards (PADIS, AIDX).

• API Management:

  Develop and maintain high-performance interfaces between internal systems and external GDS/PSS endpoints (SOAP/REST, XML/JSON).

• Production Ownership:

  Own the triage, root cause analysis, and permanent resolution of GDS/PSS-related incidents. Troubleshoot PNR/ticketing discrepancies and message-queue failures.

• On-Call Leadership:

  Participate in an on-call rotation to provide rapid response for critical booking and ticketing systems.

• Strategic Collaboration:

  Work cross-functionally with revenue management, airport operations, and interline teams to translate complex business rules into technical specifications.

• Operational Excellence:

  Author and maintain technical runbooks, monitoring, and alerting systems to minimize recurring incidents and improve system stability.

• Mentorship:

  Provide technical guidance to junior engineers and influence architectural decisions for PSS/GDS-adjacent systems.

• Compliance:

  Ensure all developments align with IATA resolutions, interline agreements, and global data standards.

Required Qualifications

• Extensive experience in software engineering using the .NET framework, with a focus on mission-critical, high-availability systems.

• Proven technical expertise in airline PSS/GDS integration (Amadeus, Sabre, Travelport, etc.).

• Deep understanding of travel industry messaging standards (EDIFACT, Type A/B, XML, JSON).

• Demonstrated experience in production support and incident management within a high-pressure environment.

• Strong analytical skills with the ability to perform root cause analysis on complex distributed systems.

• Ability to translate complex airline business requirements into scalable, reliable technical solutions.

Nice-to-Have

• Experience with NDC implementation (IATA NDC schemas, aggregators like Farelogix/Accelya).

• Exposure to interline/codeshare workflows, IROPS (irregular operations) handling, or revenue accounting reconciliation.

• Familiarity with cloud infrastructure (AWS/Azure/GCP) and containerization technologies (Docker/Kubernetes).

• IATA or relevant airline industry certifications.

• Prior experience working directly with airline operations, revenue management, or customer service teams.

What We Offer

• Competitive Compensation & Security:

  Comprehensive medical insurance coverage and end-of-service gratuity.

• Travel Benefits:

  Annual air ticket allowance to support your personal travel.

• Work-Life Balance:

  Generous paid time off (PTO) policy.

• Global Mobility:

  Full support for work visa sponsorship and relocation assistance where applicable.
