Bengaluru Karnataka India, Karnataka OnArrival Full time

About OnArrival Travel: OnArrival is redefining the travel tech industry by building the world’s most advanced full-stack travel platform.

Key Responsibilities:

  • Architect and Scale: Design and optimize OnArrival’s hotel infrastructure to handle high traffic, ensuring fault tolerance, security, and resilience.
  • API Development: Build and enhance high-performance RESTful and GraphQL APIs that power our hotel module.
  • Supplier Integrations: Integrate and optimize connectivity with global hotel suppliers, aggregators, and direct properties to ensure the best inventory and pricing.
  • Metadata & Search Optimization: Design caching and data indexing strategies using Redis, ElasticSearch, and MongoDB to deliver ultra-fast property search results.
  • Reliability and Observability: Implement distributed tracing, logging, and monitoring to ensure system reliability.
  • Security & Compliance: Ensure adherence to SOC 2, ISO, and PIPA security standards, with a focus on data localization.
  • Collaboration: Work closely with product, frontend, and infrastructure teams to enhance the hotel booking experience.
  • Mentorship: Guide and mentor junior engineers, fostering a strong engineering culture within the team.

Requirements:

  • 8+ years of experience in backend engineering with expertise in Kotlin (preferred) or Java.
  • Strong background in designing high-scale distributed systems and microservices.
  • Deep understanding of MongoDB, Redis, ElasticSearch, and event-driven architectures (Kafka or Confluent).
  • Experience working with hotel industry standards such as channel managers, PMS APIs, and hotel supply aggregators (Hotelbeds, DerbySoft, RateGain, etc.).
  • Strong focus on API performance, security, and observability.
  • Experience with cloud-native architectures on AWS/GCP.
  • Familiarity with CI/CD pipelines, Kubernetes, and DevOps best practices.
  • Previous experience leading teams or mentoring engineers is a plus.
