Fullstack Engineer (MOE)

Solid full-stack experience Comfort building desktop applications Experience with hardware or device integration Experience integrating AI/ML APIs into production systems Comfort with cloud infrastructure Strong foundation in software hygiene Ability to reason about algorithmic complexity Understanding of concurrency Experience with AI-integrated systems engineering Ability to design for operational reality Build and maintain the Scanvas web platform — API routes, background job queues, database models, and the canvas-based template editor that assessment staff use to configure OMR zones. - Build and maintain the ScanController desktop application — the interface between scan-room operators, the scanner hardware, and the cloud backend. - Integrate hardware: scanner SDKs, driver interfaces (TWAIN/ISIS/WIA or vendor APIs), and scan-capture pipelines that validate quality and handle errors before upload. - Integrate AI services: LLM APIs for OMR template generation, computer vision for zone detection, and document OCR/ICR for handwritten and typed responses on mix-form booklets. - Design and optimise for throughput — job queues, concurrency limits, rate-limited external AI calls, and S3 storage pipelines that must sustain peak exam-season load. - Collaborate with the Product Manager and operations team to turn real scan-room workflows into software that people trust under pressure. - Maintain engineering rigour: TDD, typed code, clean API boundaries, meaningful CI gates, and documentation that the next engineer can actually use. What We're Looking For The fundamentals matter most. We are not prescriptive about your current stack. Engineers who understand why systems behave the way they do pick up new frameworks quickly. Engineers who only know their current framework struggle when the problem doesn't fit the tutorial. What the fundamentals look like in practice: - You can design a system given a set of constraints and articulate the trade-offs you made. You don't need a framework to do this. - You understand concurrency — threads, event loops, async/await — well enough to reason about race conditions and bottlenecks, not just write await and hope.
