T12 TECHNOLOGIES LLC is seeking an AI Engineer to build and validate Claude workflows for an Oracle NetSuite accounts payable automation program, supporting invoice intake, extraction, GL coding, and approval routing. This contract role is based in Baltimore, MD (hybrid).
What You Will Build
- Create Claude invoice intake, extraction, and GL coding workflows tuned to the client’s historical coding patterns and vendor mix.
- Implement auto-approve versus exception routing and define human-in-the-loop thresholds for high-value transactions.
- Develop a prompt library with versioning that covers coding, duplicate rationale, exception summaries, and anomaly analysis.
- Generate ground-truth datasets from historical invoices and use them for accuracy scoring and regression checks on every workflow change.
- Validate extraction and coding outcomes against agreed targets and compile acceptance evidence documenting results.
- Build Claude-assisted investigations using duplicate saved searches, producing investigation summaries and disposition drafts.
- Create a workflow for budget-versus-actual variance commentary to support the finance team.
- Support cutover, capture baseline metrics, and participate in post-implementation hypercare.
Evaluation, Testing, and Monitoring
You will own validation through an evaluation harness, including monitoring and finance reporting workflows. You will also implement regression suites suited to non-deterministic model output, ensuring accuracy improvements reflect real gains rather than noise.
Required Qualifications
- 2+ years building production workflows on LLM APIs, with Anthropic Claude strongly preferred, including prompt engineering, structured extraction, and confidence scoring.
- Strong Python skills and REST API integration, with comfort working against a third-party ERP you did not build.
- Proven ability to perform document extraction at production quality for invoices, forms, contracts, or similar semi-structured documents.
- Experience creating evaluation sets and regression suites for non-deterministic output, with the ability to distinguish signal from noise.
- Experience with structured output and schema validation, including handling malformed or low-confidence results.
- Disciplined prompt iteration based on real data rather than synthetic happy-path examples.
- Legal authorization to work in the United States as an independent contractor.
- References: two minimum, three preferred, from production LLM work you personally built. Demos, pilots, and proofs of concept do not qualify.
Reference details required for each contact: name, current title, organization, direct phone or email, the project you worked on together, and their role on it.
Additional Notes on Verification
There is no universal certification for this role. References are contacted before any contract is issued. If you hold Anthropic, cloud provider, or ML certifications, list them with credential IDs, as T12 Technologies LLC verifies credentials.
Preferred Experience
- SuiteScript 2.x or prior NetSuite / ERP integration experience.
