About us
Otamiser is an international hospitality tech scale-up based in Ghent, building the category-defining platform for ranking management and revenue optimisation in short-term rentals and hotels. Our in-house algorithm powers the first-ever ranking management solution for and Airbnb, helping property operators consistently outrank competitors and drive a measurable 24% uplift in revenue.
We operate at the intersection of distribution intelligence, dynamic pricing, and AI-powered automation. Our products: AutoRank, Booster STR, and Listing Optimizer are used by operators wordwide, and we're scaling fast. AI agents are not a future roadmap item here, they're already running in production, and this role sits at the centre of that.
About the role
We're looking for a Full-Stack Developer who can architect for the long term while shipping in the short term and who gets genuinely excited about what agentic AI makes possible.
You think in systems. You understand how today's decisions create tomorrow's constraints, and you design accordingly. But you also follow the frontier: you know what LLMs can and can't do reliably, you've thought about how to orchestrate agents safely, and you're drawn to the challenge of turning autonomous systems into robust, production-grade products.
You'll work directly with our CPO and CTO to evolve our platform architecture and help us build the next generation of AI-native features that are already on our roadmap.
What you'll do
Lead architecture decisions across our stack: defining service boundaries, data models, API design, and integration patterns that hold up as we scale
Design and build agentic AI systems: multi-agent pipelines, LLM integrations, automation workflows, and the infrastructure to run them reliably in production
Build and extend our core web application: React frontend, Node.js/TypeScript backend
Design for extensibility: our product surface is expanding rapidly, and the foundations you lay today need to support features that don't exist yet
Proactively identify architectural risks, technical debt, and bottlenecks: and drive the roadmap to address them
Own features end-to-end, from technical design through to production and iteration
Contribute to product thinking: challenge specs, propose alternatives, catch edge cases early
Drive and improve CI/CD pipelines for fast, safe, and confident deployments
Plan for infrastructure scaling, performance optimisation, and system reliability as our customer base grows
Mentor other developers and help establish engineering standards that scale with the team
What we're looking for
5–8+ years of professional experience in software engineering
Demonstrable expertise in system architecture: you've designed and evolved production systems at scale, made hard tradeoffs, and lived with the consequences
A genuine passion for agentic AI and automation: you follow the space closely, have built with LLMs in production, and understand orchestration, tool use, memory, and reliability at a practical level
Strong production experience with React and Node.js (TypeScript)
Deep understanding of distributed systems, API design, data modeling, and service decomposition
Track record of building systems that are easy to extend, not just easy to ship
Solid grasp of performance optimisation, reliability patterns, and infrastructure scaling
Hands-on experience with cloud infrastructure and CI/CD
Product intuition: you think about users and outcomes, not just implementation
High standards for code quality, testing, and documentation
Strong communicator: able to explain architectural decisions to both engineers and non-technical stakeholders
Comfortable with autonomy and a strong sense of technical ownership
Bonus points
Hands-on experience with multi-agent frameworks (LangGraph, CrewAI, AutoGen, or similar)
Experience integrating Anthropic Claude, OpenAI, or other frontier models into production products
Built or operated automation workflows at scale (n8n, Make, Zapier at the API level, or custom)
Experience in SaaS, marketplace, or data-intensive B2B products
Interest in hospitality, travel tech, or distribution platforms
