About United Airlines

United Airlines is one of the world's major commercial airlines, connecting passengers and communities through an extensive domestic and international route network. Its operations involve far more than aircraft and airports. Behind the scenes, the company depends on sophisticated technology platforms supporting reservations, customer interactions, loyalty programs, operations, digital services, data management, and enterprise systems.

For a technology professional, an airline environment can therefore provide exposure to complex systems where reliability, security, scalability, and customer experience all matter.

United's technology organization works across areas such as software development, cloud infrastructure, data, cybersecurity, digital products, customer technology, and enterprise applications. This makes the company an interesting environment for professionals who want to apply modern engineering practices to large-scale business problems.

The Principal Developer position is particularly connected to customer data and identity technology. That means the work can influence how information from different customer interactions is brought together and used to support more relevant digital experiences while respecting privacy and governance requirements.

Key Responsibilities

1. Lead end-to-end technology development

The Principal Developer will participate throughout the software lifecycle, from understanding requirements and creating technical designs through development, testing, deployment, and ongoing improvement.

This is important because the position is not simply an architecture role. Candidates should be comfortable getting involved in actual implementation and coding.

2. Build scalable customer data platforms

The role involves developing platforms capable of handling very large volumes of customer interactions. These systems need to remain reliable while supporting data-driven applications and customer engagement.

Experience with distributed systems, cloud architecture, APIs, event-driven solutions, and high-throughput data processing can therefore be valuable.

3. Develop identity and identity-resolution solutions

Customer identity is a central part of this position. The developer will work with concepts such as identity graphs, digital identifiers, universal identities, and identity resolution.

The objective is to help technology systems understand relationships between customer information across different sources while maintaining appropriate privacy and governance controls.

4. Establish reusable engineering components

Instead of creating isolated solutions for individual projects, the role emphasizes reusable technology. A well-designed component can potentially support multiple products or teams.

This requires strong software design skills, clear interfaces, maintainable code, and an understanding of how cloud-native products can be packaged and scaled.

5. Apply AI and machine learning

AI/ML is another important area. The position calls for exploring ways to use intelligent models for identity matching, customer insights, activation, and decision-making.

Candidates familiar with Generative AI, Retrieval-Augmented Generation (RAG), and GraphRAG can bring additional value to this type of environment.

6. Support modernization

Senior technical professionals are expected to identify outdated processes and systems that can be simplified, replaced, or modernized.

This means the role requires more than technical implementation. It also involves evaluating existing architecture and finding practical ways to improve efficiency and reliability.

7. Work with multiple teams

The Principal Developer will collaborate with product managers, business stakeholders, IT professionals, data engineers, analysts, and other technical teams.

Strong communication is therefore essential because enterprise technology projects often require agreement between people with very different responsibilities.
