About this role

Who we are: Sardine is the leading agentic risk platform for fighting financial crime. Our integrated solution unifies data across risk teams to help organizations stop fraud in real time, prevent AI-driven attacks, and automate fraud and AML operations. Sardine’s platform is strengthened by one of the fastest-growing fraud consortiums in the market, spanning more than 6 billion profiled devices, 800 million consumers, and 3 million businesses worldwide.

Leading companies including FIS, GoDaddy, Intuit, Edward Jones, ZoomInfo, and Checkout.com rely on Sardine to secure and grow trust in their products. Our culture: - We hire talented, self-motivated individuals with extreme ownership and high growth orientation. - We value performance and not hours worked. We believe you shouldn't have to miss your family dinner, your kid's school play, friends get-together, or doctor's appointments for the sake of adhering to an arbitrary work schedule.

- We're a remote-first team spread across time zones, so no office to report to - work from wherever helps you do your best work. Just a couple of things to keep in mind: pay is based on where you're located, and you'll need to keep a home base in the country you're hired in. So while we love the "coffee shop today, mountains tomorrow" life, this isn't a passport-optional, work-from-anywhere-on-Earth kind of remote - think flexible within your country, not borderless.

Location: Remote — Canada (Eastern Time) To be considered for this position, you must reside in one of the following locations and be legally authorized to work in Canada: - Ontario About the Role: As a frontend-focused Senior Software Engineer, you will own the design and delivery of the user-facing experiences at the heart of our AI products. Your primary focus is building polished, performant, production-grade interfaces in React and TypeScript.

You'll also work in Go on the backend services and APIs that power those experiences, but that's a secondary part of the role. This is a high-autonomy, high-leadership position: you'll develop new features at scale, set the standard for how we build on the frontend, mentor the engineers around you, and use AI/agentic tooling (like Claude) to ship far faster than a traditional team would. The ideal candidate pairs exceptional frontend craft with the judgment to lead and the discipline to be relentlessly efficient with modern, AI-assisted workflows.
