About GradeTime

GradeTime is a web-based AI grading and analytics platform that is all about helping teachers save a huge amount of time. Interest from teachers and schools is already very strong.

Our founder has many years of experience founding and scaling successful tech businesses, looking to build a strong team for this venture.

The Role

Working closely with the founders and CTO, you will be the first and primary hands-on developer, taking the completed scope, functional/technical requirements and working Lovable prototype to a production-ready MVP — then continuing through future releases.

This role suits someone who enjoys high ownership, fast iteration, and building a product end-to-end.

Equity and salary options available for the right person. Looking for long term team member.

Responsibilities

• You will own end-to-end delivery: architecture → implementation → deployment → monitoring.
• Build a modern web app UI (desktop/laptop first), APIs, database schema, background jobs/queues, and file processing.
• Implement authentication and tenant isolation appropriate for schools. 
• Design an API to call the AI integration layer and output handling. 
• Create and execute a practical testing strategy (unit/integration/e2e, plus performance and security checks). 
• Ensure Australian data residency across data, file storage, backups, and logs.
• Set up release process, and environment management (dev/stage/prod).
• Implement monitoring/logging/error tracking and basic alerting.
• Note: the AI model/prompt design is handled in-house — you’ll be building the product and integrations around it.

Mandatory (must-have)

• Proven experience as an end-to-end senior full-stack developer (you’ve owned delivery, not just support).
• Commercial experience with React/Next.js and a TypeScript-based backend (Node.js) OR a Python backend (FastAPI/Django) in the last 2–3 years (candidates whose recent experience is primarily .NET/Java/SAP/ERP may not be a fit).
• Security fundamentals: secure coding, input validation, auth/session security, safe dependency practices.
• Secure SaaS patterns: tenant isolation, role-based access control (RBAC), audit logging, encryption in transit/at rest, safe file upload/processing, privacy-by-design.
• Solid grasp of API design, and background job processing (queues/workers) and integrating third-party APIs.
• You can work independently: scoping, sequencing, trade-offs, and communicating risks clearly.

Optional (nice-to-have)

• EdTech / schools experience.
• Familiarity with Australian privacy expectations in schools (ST4S-aligned delivery is a plus). 
• Canvas LTI experience and/or Google Classroom integrations.
• Turnitin plagiarism integrations. 
• OCR + PDF/DOCX processing, and building reliable document ingestion pipelines. 
• Data visualisation/analytics UI. 

How we work

You’ll partner directly with the founders and CTO.

Prototype + functional brief provided; you’ll help translate it into a build plan and ship iteratively.

High trust, high autonomy, clear outcomes.
