Optix is looking for a Senior Full Stack Engineer to help us build the next generation of AI-powered features in our platform. We are evolving from a rules-based automation platform into a leading conversational, agentic workspace management system.

You'll work across our backend and frontend to ship features that bring AI capabilities to life for coworking and flex space operators, the people running the workspaces that are reshaping how the world works. Partnering closely with our Technical Lead, Product, and Design, you'll deliver features end to end, with room to take on more technical-design responsibility as you grow with us.

This is a rare opportunity to deepen your AI expertise through hands-on agentic work and mentorship from experienced AI leadership, all within a profitable, proven SaaS company, while you leverage your strong full-stack fundamentals to ship meaningful features.

Note: This is a hybrid opportunity for someone based in Vancouver, BC (60% in our beautiful waterfront Gastown office, 40% from home).

Required skills and experience

6+ years of full-stack engineering experience, with a track record of reliably delivering features end to end
Strong backend fundamentals, including building and scaling APIs (REST and/or GraphQL) and a solid grasp of databases and data-flow patterns
You've built something real with LLM APIs and understand in practice how they behave, including their quirks and failure modes
You are comfortable in Python and familiar with the LangChain ecosystem
You understand that AI features demand different thinking about quality, testing, and UX than deterministic features
You use AI tools (e.g. Claude) fluently to accelerate and debug your own engineering
Strong problem-solving and systems thinking about integration patterns
Comfort with Git, unit testing, CI, and the Linux command line, plus a habit of writing maintainable, testable code in complex systems
You can clearly articulate technical reasoning to technical and non-technical teammates, and work well both independently and collaboratively

Strongly preferred

PHP / Laravel, MySQL, and GraphQL
Vue.js, with comfort working in an established, maturing codebase rather than greenfield
Experience with hub-like systems that integrate many external services (e.g. payments, calendars, access control), rather than single-purpose apps
Hands-on experience with agentic / LLM application patterns: multi-step orchestration, tool use, prompt and context management
Experience evaluating and monitoring AI quality (evals, tracing, accuracy testing)
AWS (Bedrock, ECS), containerization, and CI/CD

Bonus

Data engineering exposure (ETL, transformations, larger datasets)
Microservices and event-driven architectures
Prior B2B SaaS experience

What You'll Do

Deliver full-stack features across backend and frontend in a Jira-based Agile sprint, taking ownership of your tickets, with the opportunity to grow into broader technical-design decisions over time
Build AI-powered features that deliver meaningful value to our customers
Develop the integrations and full-stack experiences that bring AI capabilities into an intuitive UI, including some data work where needed
Design and evolve APIs that our iOS and Android apps depend on, with care for backward compatibility across releases
Use Claude and other AI tools as a daily accelerator and debugger in your own engineering
Partner with our Tech Lead on evaluation and monitoring that keeps AI feature quality high
Contribute to ongoing improvements to our platform and architecture
Work cross-functionally with Product and Design, shaping technical direction for customer impact, and contribute to planning and estimation
Raise the bar on quality: grow test coverage, review code, support QA and release-candidate readiness, and validate acceptance locally and on our QA environment
Engage in deep-dive investigations and rare edge case discovery across a large client base
Participate in sprint rituals

We take care of our teammates

This is a unique opportunity to join a rapidly growing technology startup. Taking care of our team on this journey is a priority. We offer:

Competitive salary compensation and commission structure
Strong Employee Stock Option Plan offering
Excellent health and dental coverage program provided by Sunlife
Mission-driven workplace experience with a positive, collaborative and supportive team culture
Personal and professional growth opportunities
Healthy snacks and locally roasted coffee – slow pour is our jam
Team lunches and socials
Annual health and fitness credit
Fun offsite activities that allow us to reconnect as a team
A beautiful, waterfront Gastown office and a flexible 60/40 hybrid workplace plan
