Senior Full Stack Engineer, App Runtime

Department: Engineering

Location: CA-Ontario-Toronto

Compensation: CA$245,250 – CA$295,250

Employment Type: FullTime

At Snowflake, we are powering the era of the agentic enterprise. To usher in this new era, we seek AI-native thinkers across every function who are energized by the opportunity to reinvent how they work. You don’t just use tools; you possess an innate curiosity, treating AI as a high-trust collaborator that is core to how you solve problems and accelerate your impact. We look for low-ego individuals who thrive in dynamic and fast-moving environments and move with an experimental mindset — who rapidly test emerging capabilities to discover simpler, more powerful ways to deliver results. At Snowflake, your role isn't just to execute a function, but to help redefine the future of how work gets done.

About the role

The App Runtime team is building a platform that lets every Snowflake user go from an idea to a live, deployed web application (Node.js first) in minutes. We own the end-to-end experience of building and running apps, from Cortex AI-assisted development to deployment in a secure, scalable infrastructure. Apps built on the platform inherit Snowflake's security, governance, lineage, and access controls by default. See Deploy Faster with Snowflake Apps.

As a Senior Full Stack Engineer, you will drive initiatives that span our product areas and tech stack. It’s a high-impact role - you will work on an early-stage, public-preview product. Your work will directly shape the product experience developers rely on. This role requires a unique combination of deep hands-on expertise with web frameworks, great UX design instincts, customer obsession and collaboration with backend teams.

Responsibilities

• Build the AI-assisted, agentic development experiences that power App Runtime, spanning the full tech stack - React, Go, Python, and Java

• Stay deeply hands-on by authoring technical and design specs that consider the system holistically (frontend and backend) and implementing critical code

• Partner directly with customers, i.e. developers building Snowflake Apps, translating their needs into features and improvements

• Raise the bar for quality, reliability and performance through code review; mentor engineers

• Coordinate closely with sister teams such as Cortex AI, Container Platform or Security

Requirements:

• Bachelor’s degree in Computer Science, Engineering or a related field. Master’s or higher is preferred but not a requirement

• 5+ years of experience including significant experience in frontend or full-stack software development, with a demonstrated track record of designing, shipping and operating high-scale systems

• Deep understanding of modern web application architecture (e.g. React, NextJS), good API design patterns, security, performance and scale; proficiency in TypeScript/JavaScript, ideally also in Go, Python and/or Java

• Good communication skills: crisp write-ups, constructive debate, and ability to drive consensus across engineering, design and product

Nice to have:

• Experience shipping 0-1 products where you skillfully balanced the trade-offs between feature completeness and time-to-market

• Experience with multi-tenant systems (ideally app hosting platforms or tooling for developers) with strong isolation and a security-first posture

• Technical leadership experience, such as being an architect or tech lead for high-impact customer-facing products

Snowflake is growing fast, and we’re scaling our team to help enable and accelerate our growth. We are looking for people who share our values, challenge ordinary thinking, and push the pace of innovation while building a future for themselves and Snowflake.
