In this role, you will:

• Design, build, and maintain robust, scalable, and secure backend services and APIs, including detailed low-level design, API contracts, and data models that support high-availability travel applications.

• Lead end-to-end implementation of complex features across services, ensuring code quality, reliability, and observability through effective testing, monitoring, and alerting practices.

• Collaborate with product, architecture, and cross-functional engineering teams to refine requirements, decompose problems, and deliver solutions that perform reliably under real-world production load and scale.

• Drive improvements in system design, performance, and operational excellence by identifying bottlenecks, optimizing data access patterns, and enhancing deployment, CI/CD, and incident management practices.

• Safely integrate and operate AI/ML‑enabled solutions that improve outcomes, and apply familiarity with AI-driven systems, tools, or workflows and AI/ML concepts to enhance real-world products and engineering efficiency.

• Contribute to a culture of technical excellence by mentoring other engineers, promoting engineering best practices, and building solutions that are reusable and fungible across multiple services and domains.

Minimum Qualifications:

• Bachelor’s degree in Computer Science or a related technical field; or Equivalent related professional experience.

• 5+ years of relevant professional experience.

• Proven ownership of service-level components or multiple related services, including responsibility for design, implementation, quality, deployment, and ongoing operations.

• Strong skills in system design (including low-level design), API design, and data modeling, with an understanding of performance, scalability, security, and reliability trade-offs.

• Hands-on experience with modern development practices such as automated testing, CI/CD, code reviews, and production monitoring for highly available systems.

Preferred Qualifications:

• Experience architecting and evolving complex, distributed, or event-driven systems at scale, including making data-driven decisions on technology choices, system decomposition, and integration patterns.

• Demonstrated leadership in improving service reliability and operational excellence, such as driving incident reviews, reducing toil through automation, and enhancing observability across services.

• Depth in database and storage technologies (e.g., relational and/or NoSQL), including schema and data model design, query optimization, and performance tuning for high-traffic applications.

• Familiarity with AI-driven systems, tools, or workflows and applying AI/ML concepts to real world products, including safely integrating and operating AI/ML‑enabled solutions that improve outcomes in areas such as personalization, recommendations, or developer productivity.
