Description

We are looking for a Junior API Integration Specialist (Hotel Systems) to join Hotel Res Bot, a fully remote SaaS company building automation for hotel communications and operations.

This is not a standard API role. Hotel technology is highly fragmented, and external systems (especially PMS platforms, booking engines, and payment providers) are often inconsistent, poorly documented, and designed with assumptions about hotel operations that are not always clearly specified.

A core part of this job is working in that reality: understanding how hotel systems actually behave in production, not just how they are described in documentation. This often requires testing, experimentation, and reverse-engineering system behaviour when APIs are incomplete or contradictory.

You will work directly with hotel APIs and use Postman to test, validate, and debug real-world workflows such as reservations, availability (ARI), rate plans, restrictions, and group blocks.

Your output will be structured, implementation-ready tasks for engineers.

Responsibilities:
  •  Analyse and interpret hotel system API documentation (often incomplete, inconsistent, or misleading in practice) 
  •  Work hands-on with PMS, booking engine, and payment provider APIs in real-world conditions 
  •  Build, test, and debug API requests using Postman 
  •  Reverse-engineer API behaviour when documentation does not match real system behaviour 
  •  Validate hotel workflows through APIs, including: 
    •  Reservations (create, modify, cancel, including edge cases and vendor-specific behaviour) 
    •  Availability, Rates & Inventory (ARI logic across inconsistent implementations) 
    •  Room types and rate plans (often not standardized across systems) 
    •  Restrictions (min/max stay, closed dates, allotments) 
    •  Group blocks and allocation logic (frequently under-documented) 
    •  Guest, company, and travel agency profiles 
    •  Guarantee, payment, and cancellation rules (varies significantly by system) 
  •  Identify gaps between hotel operational reality and API documentation 
  •  Work with logs and API responses to debug integration issues 
  •  Translate findings into clear, structured GitLab tasks for developers 
  •  Collaborate with engineering on unclear or ambiguous integration behaviour 
  •  Occasionally support troubleshooting calls with PMS providers when documentation is insufficient 
  •  Maintain internal documentation of real-world system behaviour vs documented behaviour

Requirements

We are looking for someone with hotel operations experience, structured thinking, and the ability to work confidently in ambiguous technical environments.

You do not need to be a developer, but you must be comfortable working in systems where:

  •  documentation is incomplete or incorrect 
  •  behaviour differs between vendors 
  •  and the only reliable truth is what the system does when tested 
Required experience:
  •  At least 1 year in hotel operations (front desk, reservations, revenue, or systems roles) 
  •  Strong understanding of PMS systems and real hotel workflows 
  •  Practical exposure to reservations, rates, availability, and booking logic 
  •  Experience with at least one hotel system (PMS or similar) 

Nice to have

  • Basic understanding of REST APIs (request/response, endpoints, payloads) 
  •  Ability to construct and modify JSON (and/or XML) payloads 
  •  Understanding of authentication methods (API keys, OAuth, tokens) 
  •  Comfort working with systems that do not behave exactly as documented 
  •  Independent problem-solving in ambiguous technical environments 
  •  Strong written communication in English 
  •  Ability to work in a scrappy, fast-moving environment without full specifications

Perks

Fully remote position (work from anywhere)  Flexible working hours with high autonomy  Direct access to engineering and product teams (no heavy hierarchy)  High ownership over your work and integrations  Strong learning environment in both hotel systems and API integrations  Opportunity to grow into: 
  •  Technical Product roles 
  •  Advanced integration specialist roles 
  •  Backend development (Go) if desired 
 Company-provided equipment (laptop and necessary tools)  Startup environment with fast decision-making and low bureaucracy
