Résumé du poste

Otamiser, Ghent-based hospitality tech scale-up, seeks a Senior Full-Stack Developer to architect for long-term success while delivering quickly. You will shape our AI-native platform, orchestrate multi-agent workflows, and drive production-ready features across a React frontend and Node.js backend.

You will partner with the CPO and CTO to evolve the architecture, address risks, and raise the bar for reliability, performance, and extensibility as we scale internationally.

Qualifications

• 5–8+ years of professional experience in software engineering.
• Demonstrable expertise in system architecture: designed and evolved production systems at scale.
• A genuine passion for agentic AI and automation: production with LLMs, orchestration, reliability.
• 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 extensible systems, not just shipping.
• Solid grasp of performance optimization, reliability patterns, and infrastructure scaling.

• High standards for code quality, testing, and documentation.
• Strong communicator: explain architectural decisions to engineers and non-technical stakeholders.
• Autonomy and strong technical ownership.
• 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 API level).
• Experience in SaaS, marketplace, or data-intensive B2B products.

Responsabilités

• Lead architecture decisions across the stack: service boundaries, data models, API design.
• Design and build agentic AI systems: multi-agent pipelines, LLM integrations, automation workflows.
• Build and extend core web application: React frontend, Node.js/TypeScript backend.
• Design for extensibility to support future features.
• Identify architectural risks, debt, and bottlenecks; drive roadmap.
• Own features end-to-end from design to production and iteration.
• Contribute to product thinking; challenge specs and edge cases.
• Drive and improve CI/CD pipelines for fast, safe deployments.
• Plan infrastructure scaling, performance optimisation, and reliability as customer base grows.
