Experience Required: 4+ Years

• 4+ years of hands-on experience with Python.
• Strong production experience with FastAPI.
• Proven experience with PDF processing libraries (e.g., PyPDF2, pdf2image).
• Experience integrating LLM APIs for document analysis or classification (GPT-4 Vision API preferred).
• Hands-on experience with Google Cloud Platform (GCP), including Cloud Storage, Firestore, and Cloud Tasks.
• Strong understanding of asynchronous job patterns (background workers, task queues, retry and failure recovery mechanisms).
• Solid systems thinking with an emphasis on error handling, data lineage, and audit trails.
• Experience designing or working with document taxonomies, classification schemas, and structured labeling systems for AI workflows.

What We’re Looking For

• A backend engineer who thinks in terms of systems, architecture, and failure modes, not just APIs.
• Strong ownership mindset toward edge cases, long-running workflows, and exception handling.
• Ability to translate ambiguous document inputs into structured, explainable, and auditable outputs.
• Comfortable working in a document-heavy, AI-assisted backend environment.
• Self-driven professional capable of thriving in a remote, part-time engagement.
