Senior Software Engineer - AI Experiences [Remote]

$185k - $210k
Full-time

Sardine

Ontario, CA
  • Remote job
Who we are:

We are a leader in fraud prevention and AML compliance. Our platform uses device intelligence, behavior biometrics, machine learning, and AI to stop fraud before it happens. Today, over 300 banks, retailers, and fintechs worldwide use Sardine to stop identity fraud, payment fraud, account takeovers, and social engineering scams. We have raised $145M from world-class investors, including Andreessen Horowitz, Activant, Visa, Experian, FIS, and Google Ventures.

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
  • Annual Learning stipend

Join a fast-growing company with world-class professionals from around the world. If you are seeking a meaningful career, you found the right place, and we would love to hear from you.
