Job Description

As a Senior Backend Engineer, you will contribute to the design and evolution of distributed backend systems that power the end-to-end protection lifecycle from eligibility and quoting to purchase, servicing, claims, cancellations, refunds, reporting, and reconciliation. This is a backend/platform-focused engineering role centered around APIs, integrations, scalability, operational excellence, and distributed systems.

Job Responsibility

  • Design, build, and maintain scalable backend services and APIs using JVM technologies such as Java or Kotlin, and Spring Boot
  • Develop integration layers with third-party insurance and assurance providers
  • Build systems supporting the full Trip Protection lifecycle, including eligibility, quoting, purchase, servicing, claims, cancellations, and refunds
  • Design clean, maintainable, observable, and testable software using sound software engineering principles and design patterns
  • Create APIs and backend workflows consumed by multiple internal and external partners
  • Contribute to architecture and technical design discussions for moderately complex distributed systems
  • Collaborate cross-functionally with product, platform, compliance, finance, and partner teams
  • Support production systems through monitoring, debugging, troubleshooting, and operational improvements
  • Participate in code reviews and help guide engineering best practices across the team
  • Contribute to reporting, reconciliation, and operational data flows required to support the business
  • Work closely with stakeholders to deliver scalable platform capabilities across multiple markets and lines of business

Requirements

  • 5+ years of professional software engineering experience with a Bachelor’s degree, or 3+ years with a Master’s degree
  • Strong backend engineering experience building and operating production systems at scale
  • Strong proficiency in JVM-based technologies, where Java and Kotlin are preferred, and Spring Boot
  • Experience designing and building APIs and integrations between distributed systems
  • Experience working with cloud-native architectures in public or hybrid cloud environments
  • Strong understanding of microservices, asynchronous processing, and service-oriented architectures
  • Experience with SQL and/or NoSQL databases and scalable data access patterns
  • Experience with observability, monitoring, logging, alerting, and production troubleshooting
  • Ability to design maintainable, modular, and testable systems with strong operational awareness
  • Understanding of software design principles, data structures, and distributed systems fundamentals
  • Experience working in agile engineering teams and collaborating across organizational boundaries
  • Strong debugging and problem-solving skills in complex production environments
  • Ability to communicate technical concepts clearly across engineering and business stakeholders

Nice to have

  • Experience in travel, fintech, insurance, e-commerce, or other highly regulated domains
  • Experience with event-driven architectures and messaging systems
  • Familiarity with compliance-sensitive systems and operational workflows
  • Exposure to frontend/customer-facing flows is a plus, but this role is primarily backend/platform focused

What we offer

  • The chance to join an organization with triple-digit growth that is changing the paradigm on how software products are built
  • The opportunity to form part of an amazing, multicultural community of tech experts
  • A highly competitive compensation package
  • Medical insurance

  • You’ve led backend projects from start to finish — shaping architecture, guiding trade-offs, and delivering reliable systems that support real-world product needs
  • You have strong systems thinking. You look beyond the immediate task, anticipate downstream effects, and help teams converge on architecture that supports the long game
  • You’ve worked across teams to drive platform or infrastructure improvements — whether simplifying service boundaries, improving observability, or evolving internal tooling
  • You’ve contributed to collaborative or multi-user product features, and you understand the data, consistency, and UX considerations that come with them
  • You’re fluent with modern AI tools — not just using them for code generation, but integrating them into how you debug, document, explore ideas, and reduce manual effort
  • You care about performance, scale, and clean abstractions — and know how to measure, prioritize, and improve them pragmatically
  • You’ve influenced engineering culture through code reviews, mentoring, or leading by example, and you’re comfortable being a resource for others on architectural decisions
  • You have a personal stake in the world of content creation
Job Responsibility

  • Collaborate closely with engineers, product, and design to scope work, explore trade-offs, and find the simplest path to something great
  • Make steady improvements to performance, reliability, and data modeling, helping us scale quality over time
  • Participate in on-call rotation (all engineers take on a 24/7 week-long shift once a quarter on average) and day-to-day maintenance work required to keep the lights on the systems owned by the team (this includes bug fixing, addressing security vulnerabilities, incident follow-ups, etc.)
