Join Optix, a leading SaaS company in the coworking and flex space industry. As a Senior Full Stack Engineer, you will work on both platform development and AI-powered features.

• Concevoir et faire évoluer des fonctionnalités de plateforme, en utilisant des outils d'IA pour travailler sur notre pile technologique Laravel et Vue.
• Participer à l'évolution de la plateforme vers un système de gestion d'espace de travail conversationnel et agentique, en construisant des fonctionnalités qui apportent des capacités d'IA à nos opérateurs.
• Collaborer étroitement avec notre responsable technique, le produit et le design pour livrer des fonctionnalités de bout en bout, avec la possibilité de prendre plus de responsabilités en matière de conception technique.
• You thrive in large, legacy-carrying codebases. You own quality end to end through testing, CI, and code review, and you know how to leave a complex system better and more maintainable than you found it
• Fluent with relational databases and APIs. You design schemas, write and tune real SQL, and you know how to build and consume REST/GraphQL
• You can clearly articulate technical reasoning to technical and non-technical teammates, and work well both independently and collaboratively
• Depth in one convention-driven MVC framework (Laravel, Rails, Django, Spring, .NET) and one component-based JS framework (Vue, React, Angular). You will be in Laravel and Vue here; we mostly care that you go deep, not that you have used our stack
• You take an AI-first approach to building software. AI writing code is the standard here. You direct tools like Claude Code and Cursor to produce the majority of your output, and you've developed the judgment to review, guide, and correct what they generate. This is how we work day to day
• 6+years building and shipping full-stack web apps, with features you owned end to end and then lived with in production
• Prior B2B SaaS experience
• You've built something real on LLM APIs and understand how to get reliable results from them in production
• PHP/Laravel and Vue.js (Vuetify, Vuex)
• Familiarity with AWS (Bedrock, ECS/Kubernetes), containerization, CI/CD
• You are comfortable in Python and familiar with the LangChain ecosystem
• Experience with hub-like systems integrating many external services (payments, calendars, access control)
• We welcome applicants from all walks of life. Even if you don’t feel you meet every requirement listed, we would still love to hear why you think you would be an awesome addition to our team, and we encourage you to apply
• Data engineering exposure (ETL, transformations, larger datasets)
