Full Stack Software Engineer

Key Responsibilities:

• Build and maintain the web platform, including backend APIs, background job processing, database models, and the browser-based template editor used to configure OMR zones
• Develop and maintain the desktop application that interfaces with document scanners and the cloud backend
• Integrate scanner hardware using industry-standard drivers, SDKs, and vendor APIs to support reliable document capture, quality validation, and upload workflows
• Integrate AI services, including LLMs for template generation, computer vision for layout detection, and OCR/ICR technologies for processing handwritten and printed responses
• Design and optimize high-throughput processing pipelines, including job queues, concurrency management, rate-limited AI integrations, and cloud-based object storage
• Collaborate closely with Product Managers and Operations teams to translate real-world document processing workflows into reliable software solutions
• Maintain high engineering standards through test-driven development (TDD), strongly typed code, clean architecture, CI/CD pipelines, and comprehensive documentation

Requirements:

• Strong software engineering fundamentals, with the ability to quickly adapt to new frameworks and technologies
• Ability to design systems based on defined constraints and clearly articulate technical trade-offs without relying on specific frameworks
• Strong understanding of concurrency, including threads, event loops, and async/await, with the ability to identify race conditions and performance bottlenecks
• Strong testing discipline, with a proactive approach to writing tests to ensure code quality, reliability, and prevent regressions
• Strong debugging skills across system boundaries, including network calls, OS drivers, and hardware devices, with a methodical approach to complex issues
• Solid full-stack experience—web frontend, backend APIs, and relational databases. The specific framework matters less than the depth of understanding behind it
• Comfort building desktop applications, whether native, Electron-based, or equivalent. You understand the operational differences between shipping a web app and shipping a binary that runs on someone else’s managed machine
• Some experience (or genuine appetite for) hardware or device integration—SDKs, serial/USB interfaces, vendor APIs, and driver-level debugging. You don’t need to be an embedded engineer, but you shouldn’t be intimidated by it either
• Experience integrating AI/ML APIs into production systems—not just calling an endpoint, but handling rate limits, retries, token budgets, prompt versioning, and evaluating output quality
• Comfort with cloud infrastructure: containers, managed services, object storage, and job queues. You understand what runs where and why
• Strong foundation in software hygiene: version control discipline, automated testing, code review, and CI/CD

Preferred Qualifications:

• Experience with image processing pipelines (ingest, validate, transform, and store at scale)
• Prior work in the Singapore Government Tech Stack
• Familiarity with OMR, document scanning, or similar high-throughput document processing contexts
• TypeScript, Next.js, and C#—our current stack. Mention it if you know it, but don’t let unfamiliarity stop you from applying
