Job description

Treasure AI is the agentic experience platform built to acquire, retain, and grow your most valuable customers. Powered by AI, Treasure AI is shaped by human creativity and always-on through continuous, context-driven action.

Furthermore, Treasure AI employees are enthusiastic, data-driven, and customer-obsessed. We are a team of drivers—self-starters who take initiative, anticipate needs, and proactively jump in to solve problems. Our actions reflect our values of honesty, reliability, openness, and humility.

Your Role

We are looking for a Staff Fullstack Engineer to join our high-performing team working at the intersection of our Realtime and Personalization products. This is a pivotal moment for our platform: you will help drive the technical direction as we build an AI-native system, developing true, industry-leading systems that empower marketers to build in new ways.

In this role, you will act as a high-level individual contributor and technical anchor within a squad-based model. While your core expertise may lay in either complex frontends or robust distributed backend systems, you possess the architectural vision to design and mentor others across the full stack. This is a hands-on, high-impact role. You will work out of our Vancouver office three days a week, collaborating directly with product managers and designers to ship features that have a tangible impact on our customers' ability to generate value from their data.

Responsibilities

• Drive the end-to-end technical architecture for our product features. You will make high-stakes technical decisions that balance speed of delivery with long-term maintainability.
• Leverage AI-powered discovery and productivity tools (e.g., Glean, Claude Code and Gemini) to accelerate development cycles, synthesize internal technical documentation, and surface architectural context from across the organization.
• Champion AI-native engineering workflows by integrating generative AI into the software development lifecycle—from automated unit testing and agent-accelerated code workflows to drafting comprehensive technical specifications.
• Ensure a focus on outcomes and ensure your squad is unblocked whether it is frontend or backend code and provide technical guidance to your peers.
• Deeply focus on design across the entire stack. You will weigh in on how React applications should be structured even if you are working on the backend to ensure consistency across the entire stack and unblock every engineer in your squad.
• Partner with Product Managers and Engineering Managers in a squad model to deliver projects on time. You will break down complex requirements into executable engineering tasks. You may serve as a tech lead for a squad.
• Elevate the engineers around you. You will mentor Senior and mid-level engineers, modeling best practices in code review, design patterns, and operational excellence.
• Build with a mind toward scalability, observability, and security. You will join the on-call rotation and treat production operations as a first-class citizen.

Job Requirements

• 8+ years of software engineering experience, with a strong track record of shipping complex products.
• AI fluency, with a proven ability to integrate AI-assisted development tools into your daily workflow to enhance code quality, velocity, and system understanding.
• A proactive mindset toward AI adoption, demonstrating comfort experimenting with emerging AI-powered systems to streamline engineering processes and reduce cognitive load.
• Deep proficiency in backend development (experience with Ruby, Go, Java, or Kotlin is preferred). You understand database design, and API scalability and as a strong bonus have dealt with distributed systems or LLMs in production.
• You have strong architectural knowledge of the React ecosystem. You may prefer backend work, but you understand how to build a frontend architecture that is modular and testable and are able to mentor engineers in React best practices.
• You thrive in agile, collaborative environments. You are a driver—you identify blockers and remove them.

Preferred Qualifications

• Experience building or integrating Generative AI/LLM solutions into production workflows, especially with agents.
• Experience with Ruby on Rails is a significant plus.
• Experience with distributed systems.
• Experience working in global teams, coordinating with engineers in different time zones.

Physical Requirements

Working out of our Vancouver, BC office according to our “Global Hybrid Working Policy.”

Travel Requirements
