GDI / Document Intelligence & NLP Specialist

ATS+Partners is seeking a GDI / DocumentIntelligence & NLP Specialist who brings verifiable, multi-year experienceimplementing Intelligent Document Processing and Generative DocumentIntelligence solutions — ideally for government or regulated-industry clients —with documented extraction accuracy benchmarks from prior deployments. Thisrole exists specifically to address the two most consequential gaps in thecurrent proposal:

Minimum Criterion 1 requires five or more years ofexperience implementing AI Automation and GDI solutions, preferably formunicipal or government clients. The contractor’s own professional history mustprovide the concrete, dated implementation record that satisfies thisthreshold.

Minimum Criterion 2 requires a proven ability toachieve 80%+ data extraction accuracy on unstructured documents. The contractormust be able to supply documented benchmark results from prior engagements —not theoretical capability claims — that an evaluator can verify.

The contractor will serve as the project’sextraction engine expert, responsible for the design, configuration, andcontinuous improvement of all AI document extraction pipelines. They will ownprompt engineering for all four target workflows, configure the modelensemble’s consensus logic, build the field-level confidence scoring framework,and manage the human-in-the-loop feedback loop that drives continuous accuracyimprovement throughout the three-year contract term.

Design and configure AI extraction pipelines for allfour target workflows: Invoice Processing, Vehicle Insurance CertificateReconciliation, Health Insurance Reconciliation, and Audit Preparation.

Develop and maintain custom prompt templates for GPT-4oand Claude AI, including field extraction schemas in JSON format, field-levelinstructions with positive and negative examples, chain-of-thought validationprompts, and conditional extraction rules.

Configure the LangGraph consensus orchestration layer:define how discrepancies between the two model outputs are resolved, whatconfidence thresholds trigger automatic pass-through vs. HITL routing, and howreviewer corrections are captured in graph state for retraining.

Build and manage the document classification pipeline:design the taxonomy for audit document categorization, train or configure theclassifier against City document samples, and validate classification accuracy.

Establish and execute the accuracy benchmarkingprotocol: define hold-out test sets for each workflow, run pre-pilot benchmarks, pilot accuracy benchmarks, and quarterly productionaccuracy audits.

Lead prompt regression testing: maintain a library ofannotated sample documents that are re-run against every prompt update andmodel version change to detect accuracy regressions before they reachproduction.

Manage the continuous learning loop: export reviewercorrections from the HITL queue, curate training data, coordinate modelfine-tuning or prompt updates on a quarterly basis.

Configure pre-processing pipeline parameters: imagequality thresholds, deskewing settings, multi-page document segmentation rules,and PDF/A normalization parameters for each document type.

Provide domain-specific extraction expertise for ACORDinsurance certificates, government invoices, AP aging schedules, GL trialbalances, and health insurance enrollment forms.

Document all extraction schemas, prompt versions,confidence threshold configurations, and model accuracy results in aversion-controlled Model Registry maintained throughout the contract.
