Integrate external travel APIs (GDS, hotel / car / flight aggregators, or custom vendor APIs)

and build webhooks for real-time updates (e.g., booking confirmations, cancellations).

Architect and implement secure data flows, including handling of PNR data, customer

profiles, and fare / rate data.

Design and optimize normalized relational database schemas (PostgreSQL, MySQL)

and manage NoSQL collections (MongoDB) when needed.

Optimize database performance with indexing, query tuning, and caching strategies

(Redis).

Ensure application and data security : encryption, secure authentication (JWT, OAuth2),

validation, and adherence to PCI and OWASP best practices.

Write unit, integration, and end-to-end tests to maintain code quality.

Collaborate with product, QA, and design teams to translate complex travel business

requirements into scalable technical solutions.

Participate in code reviews and mentor junior developers.

Strong skills in designing normalized schemas, writing efficient SQL queries, and

optimizing relational databases (PostgreSQL, MySQL).

Working knowledge of NoSQL databases (MongoDB) when appropriate.

Experience with ORMs and query builders (Sequelize, TypeORM, Mongoose).

Data Security & Compliance :

Implement encryption in transit / at rest, secure authentication flows (JWT, OAuth2), and

access control.

Understanding of PCI compliance and secure handling of sensitive customer and

payment data.

Familiarity with OWASP Top 10 and real-world mitigation strategies.

Process & Collaboration :

Experience with Agile / Scrum, user stories, and technical estimation.

Git-based workflows, pull requests, and code review practices.

Clear technical documentation and communication skills.

Domain Knowledge (Travel) :

Understanding of booking flows, inventory / rate management, availability checks,

cancellations / amendments.

Familiarity with travel concepts like PNR, GDS, fare / rate APIs, and vendor integrations.

Good to have :

TypeScript experience.

Experience with CI / CD (GitHub Actions, GitLab CI / CD, Jenkins).

Containerization (Docker) and orchestration (Kubernetes).

Cloud platforms (AWS, Azure, GCP).
