Fullstack Engineer at tofu in Toronto, Ontario, CA

About the Role

We're hiring a Full Stack Engineer to join our core engineering team in Toronto. You'll own features end-to-end — from API design and data modelling on the backend to the dashboards and workflows enterprise recruiters use every day to act on Tofu's fraud and identity signals.

What You'll Do

• Build user-facing product features that surface fraud detection, deepfake analysis, and identity verification results to enterprise recruiting teams.
• Design and implement backend APIs and services connecting Tofu's detection models, scoring systems, and frontend surfaces.
• Develop responsive, accessible UIs in React that turn complex risk data into clear, actionable workflows.
• Contribute to data pipelines and integrations with ATS platforms and customer systems.
• Partner with design, product, and ML to ship features quickly without sacrificing quality.

What You'll Bring

• Ability to own and manage concurrent initiatives, with strong judgment on prioritization and trade-offs.
• A product-minded approach — you care about the user experience as much as the architecture.
• Driven and self-managed, capable of taking ambiguous problems and turning them into shipped features.
• Excellent analytical and problem-solving skills, attention to detail, and a high quality bar.
• Strong communication and collaboration with designers, engineers, and product managers.
• Ability and interest in mentoring more junior engineers.

Required Experience

• Bachelor's degree in Computer Science, Computer Engineering, or a related field.
• 5+ years of professional software engineering experience shipping full-stack products.
• Strong proficiency across the stack — Python on the backend and React/TypeScript on the frontend.
• Experience designing and consuming RESTful
• Experience building applications on cloud platforms (AWS, GCP, Azure) using Docker and Kubernetes.
• Strong proficiency in SQL.
