Job description

This is a new grad full stack role building and maintaining integrations between a modern platform and many older accounting and construction systems. A strong candidate has solid computer science fundamentals, real intern or co-op coding experience, and comfort working across both backend and frontend. The work rewards curiosity about unfamiliar legacy systems, careful testing, and the ability to ship quickly while keeping reliability high.

How it fits the AI era

The company's products use AI to read and process invoices, expenses and compliance documents, so the engineering work sits close to that automation. Much of the role is about connecting messy, old systems and making data flow reliably, which still needs human judgment, research and careful design. AI speeds up parts of the build, but understanding each system and testing edge cases stays human work.

How it builds AI experience

Working here gives hands on exposure to AI driven document processing inside a real product used by many customers. A candidate can build relevant experience by trying document extraction or classification projects and by learning how AI outputs get validated and fed into software. Familiarity with APIs and data pipelines helps connect that AI work to the systems it serves.

Worth showing

• Intern or co-op coding
• Backend and frontend work
• API integration projects
• Careful testing habits
