Software Engineer, AI Data Systems

Role overview A part-time independent contractor role focused on building reliable pipelines and agentic systems that turn difficult source material into traceable, production-grade intelligence. The work spans OCR and vision-language extraction, retrieval, and agent-driven automation across unstructured documents.

Responsibilities - Build and improve OCR and vision-language-model pipelines for laboratory reports, pricelists, screenshots, PDFs, and semi-structured documents. - Design extraction, canonicalization, entity resolution, validation, provenance, and human-review workflows. - Scale ingestion with queues, batching, retries, idempotency, caching, observability, and explicit failure handling. - Develop retrieval and RAG systems that return relevant evidence with precise citations and visible limitations. - Optimize LLM workflows across quality, latency, cost, model choice, prompting, context construction, and structured outputs. - Build agent-driven automation with constrained tools, durable state, evaluations, approval boundaries, and audit trails.

Requirements - Strong production experience with Python, SQL, APIs, backend services, and data pipelines. - Hands-on experience with OCR, document AI, multimodal or VLM extraction, or comparable unstructured-data systems. - Understanding of scalable systems including queues, concurrency, batching, caches, retries, idempotency, and observability. - Experience building retrieval, search, vector, or RAG systems and evaluating answer quality. - Practical experience optimizing LLM systems for reliability, latency, and cost rather than demo-grade work. - Ability to design agentic workflows with explicit permissions, human review, and failure recovery. - Strong product judgment and comfort working from incomplete information without hiding uncertainty.

Nice to have - Experience with document provenance, entity resolution, knowledge graphs, or temporal data. - Familiarity with browser automation, resilient web ingestion, PDF processing, or image-quality diagnostics. - Security, privacy, infrastructure operations, or production incident response experience. - Peptide, laboratory-data, life-sciences, marketplace, or regulated-data domain experience.

Benefits and work setup - Fully remote, part-time independent contractor engagement. - Applications accepted worldwide, with weekly scope and schedule agreed with the selected contractor.
