Senior​/Platform Engineer

Responsibilities

• Own our multi-tenant architecture – Design and evolve the centralized codebase that underpins all client embeds
• Build systems for branding, feature entitlements, limits, and rollout strategies per client
• Build and standardize core services – Architect and develop microservices for search, pricing, booking, points/loyalty, customer support, and content
• Define internal APIs and domain models that can support multiple suppliers (flights, hotels, cars, experiences, dining, etc.)
• Management and scaling of authentication, authorization, and security – Own integration patterns for our OAuth-based authentication pipeline with partners
• Design tenant-aware auth models to ensure strict isolation of partner data and behavior – Partner with our CTO on security, compliance, and data privacy best practices
• Architecting configuration and feature delivery – Build feature flag and configuration systems that allow safe, controlled rollout of new capabilities to specific clients or cohorts
• Design versioning and compatibility strategies so we can update the centralized codebase without breaking existing partners – Enable "configuration, not code" for common-client customizations
• Own the developer experience & standards – Define and maintain templates and libraries for new services (logging, metrics, error handling, auth, config)
• Dev Ops on CI/CD observability, and environment strategy so engineers can ship quickly and safely
• Provide technical leadership and mentorship, review designs, and raise the overall engineering bar

• Language agnostic backend engineering expert with a strong handle of at least one of the following:
  Python, C#, Java, Go, Node.js
• Experience designing, implementing, and maintaining distributed systems or microservices in a production environment
• Deep understanding of multi-tenant or white-label SaaS architectures, configuration-driven systems, and versioning/rollout strategies
• Hands‑on experience with cloud infrastructure (AWS preferred), including containerized deployments using Docker and Kubernetes
• Strong fundamentals in API design, service boundaries, domain modeling, and building internal platform abstractions used by multiple product teams
• Experience working with databases at scale, ideally Mongo
  
  DB or other No
  
  SQL document stores, including scheme design, indexing, and performance considerations
• Comfortable working with (or designing for) microservices or BFF layers that feed frontend UIs
• Solid understanding of authentication and authorization, especially OAuth2/OIDC, JWTs, tenant isolation, and secure service-to-service communication
• Familiarity with modern CI/CD tools and workflows (Bitbucket Pipelines or equivalent), including automated testing, linting, and deployment pipelines
• Ability to drive architectural discussions, write design docs/RFCs, mentor other engineers, and lead cross-team technical initiatives
• Proven track record of technical leadership at the staff/principal level: mentoring, reviewing, and influencing architecture beyond your own code

• Experience with travel, fintech, loyalty, or other integration‑heavy domains
• Background working with embedded/partner‑hosted experiences and complex integration contracts
• Experience with AI‑assisted coding tools such as GPT‑Codex, Cursor, Clause Code, Git Hub Copilot, or similar LLM‑powered development environments
• Familiarity with prompt engineering and structuring context for effective AI‑driven code generation and refactoring
• Comfortable using LLM tools to prototype services, draft integrations, analyze logs, generate tests, and accelerate repetitive coding tasks
• Enthusiasm for vibe coding workflows—using AI as a creative accelerator while maintaining strong engineering judgment and code quality
