Job description

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 have hubs in the Bay Area, NYC, Austin, Toronto, and São Paulo. However, we maintain a remote-first work culture. #WorkFromAnywhere

- 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.

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.

What you'll be doing:

- Design, build, and own user-facing features in React and TypeScript — polished, accessible, performant, and production-ready.

- Set the technical direction and quality bar for our frontend, and lift the people around you through mentorship and code review.

- Use AI and agentic development tools (such as Claude) fluently and effectively to move quickly, and help establish best practices for AI-assisted development across the team.

- Dip into Go to build and extend the backend services and APIs behind your features when needed.

- Collaborate closely with business stakeholders to architect and implement new experiences from inception to delivery.

- Contribute to product and technical roadmaps, and to the broader direction of the engineering team.

- Craft and maintain user-facing technical documentation that drives understanding and adoption of our products.

- Play a pivotal role in shaping our engineering culture and ensuring high standards across the organization.

What you'll need:

- 7+ years of proven experience as a software engineer, with deep specialization in frontend development.

- Expert-level React and TypeScript, with a strong eye for UX, performance, and accessibility.

- Demonstrated fluency with AI and agentic coding tools (e.g., Claude), and a track record of using them to ship efficiently and raise your own throughput.

- Leadership experience: setting technical standards, mentoring engineers, and driving key technical decisions.

- A track record of shipping high-quality, production-grade frontend at scale.

- Working proficiency in Go (or the ability to become productive in it quickly) for backend services — secondary to your frontend work.

- Comfort with ambiguity and the ability to prioritize autonomously against business needs.

- Customer-centric approach with strong empathy toward users.

- Relevant industry experience in fintech, fraud, compliance, risk, or regulated systems is preferred.

- Proficient in English — from casual chats to formal reports.

- Exposure to data tooling or pipelines is a nice-to-have, but not required.

Technologies we use:

- TypeScript (React + Node)

- Golang

- Bigtable

- Postgres / PostgreSQL

- BigQuery

- Python

- Java

- Terraform

Benefits we offer:

- Generous compensation in cash and equity

- Early exercise for all options, including pre-vested

- Work from anywhere: Remote-first Culture

- Flexible paid time off and Year-end break

- Health insurance, dental, and vision coverage for employees and dependents - US and Canada specific

- 4% matching in 401k / RRSP - US and Canada specific

- MacBook Pro delivered to your door

- One-time stipend to set up a home office — desk, chair, screen, etc.

- Monthly meal stipend

- Monthly social meet-up stipend

- Annual health and wellness stipend

-
