Thomson Reuters is looking to solve the business problem of enhancing accounting workflows through automation, intelligence, and seamless orchestration by developing AI-powered systems.

Requirements

  • 7+ years building web applications at scale, with practical experience in both front-end and back-end development (we welcome engineers who are stronger in one area but capable in both)
  • Experience building new products or features from 0 to 1 or from ideation to release
  • Excellent debugging skills and an eye for performance optimization

Responsibilities

  • Architect and implement complete features that bring generative AI capabilities to life, alongside core product capabilities that streamline and modernize accounting workflows.
  • Design, build, and maintain generative AI products such as Conversations, Accounting Research, Ready to Advise, and Workspaces
  • Build engaging front-ends using Next.js, TypeScript, and Tailwind CSS
  • Develop robust back-ends with Python, FastAPI, Pydantic, and cloud infrastructure, including API design, data modeling, and AI service integration
  • Identify bottlenecks and optimize for speed, scalability, and responsiveness across the full stack
  • Contribute to technical design decisions across the stack, including architecture, API design, and system integration patterns

Other

  • Own complex, 6+ month projects from beginning to end, including ideation, working with cross-functional partners in product and UX, testing, launching, measuring impact, and iteration.
  • Serve as a product leader for full stack projects through making prioritization decisions, scoping out timelines, guiding the work of product and backend engineers, and collaborating with cross-functional partners.
  • Set and enforce team-wide frameworks, best practices, code quality and best practices for both front-end and back-end development
  • Apply strong design sensibilities to deliver polished, accessible, and user-centric interfaces.
  • Proactively collect feedback from end users and internal stakeholders, and iterate accordingly
