Senior Full Stack Engineer

About this role

We're Optix — enabling flex and coworking space operators to build smarter, more automated spaces and better-connected communities. Our platform powers the digital backbone of coworking and flex spaces worldwide, uniting automation, CRM, and community engagement tools into one seamless experience. Optix is looking for a Senior Full Stack Engineer to help us build and evolve the platform that powers coworking and flex space operators, the people running the workspaces that are reshaping how the world works. This role combines deep full-stack platform work with building the next generation of AI-powered production features. On the platform side, you'll employ AI tools to work across our Laravel and Vue stack, shipping features end to end, designing and evolving APIs, and helping modernize an established, legacy-carrying codebase into a cleaner, API-centric architecture. On the AI product side, you will help us evolve from a rules-based platform into a leading conversational, agentic workspace management system, building features that bring AI capabilities to life for our operators. Partnering closely with our Engineering Lead, Product, and Design, you'll deliver features end to end with room to take on more technical-design responsibility as you grow. This is a rare opportunity to strengthen your full-stack fundamentals and deepen your AI expertise through hands-on agentic work, all within a profitable, proven SaaS company with a strong engineering culture. Note: This is a hybrid opportunity for someone based in Vancouver, BC (60% in our beautiful waterfront Gastown office, 40% from home). Requirements Required skills and experience 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. 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. 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 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. You've built agentic LLM pipelines and understand how to get reliable results from them in production You are comfortable in Python and familiar with the LangChain ecosystem Familiarity with AWS (Bedrock, ECS/Kubernetes), containerization, CI/CD You trace technical decisions back to what a user actually needs, not just what's technically interesting to build. You engage actively in cross-functional discussions about where the product and platform should go next. You can clearly articulate technical reasoning to technical and non-technical teammates, and work well both independently and collaboratively.
