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.
