Job Description

As a Full-Stack Engineer specializing in JSON Schema development, you will play a crucial role in transforming complex documents into structured, actionable data models. Your expertise in schema design and data validation will enable you to build robust extraction schemas from intricate PDFs, ensuring data quality and seamless integration into downstream systems. Key Responsibilities:

• Review and analyze complex PDF documents (ranging from 25 to 150 pages) to identify relevant data fields for extraction.
• Design and implement deeply nested JSON schemas from scratch, aligning with data modeling best practices.
• Define field types, naming conventions, and hierarchical structures to accurately model nested and repeated information.
• Embed granular validation logic, such as sum checks and null-testing, to ensure data integrity.
• Collaborate with API Gateway teams to design, document, and enforce API contracts using JSON Schema standards.
• Work closely with stakeholders to refine requirements, clarify ambiguities, and deliver clear, actionable schema documentation.
• Champion strong written and verbal communication, ensuring clarity in schema explanations and implementation guidance.

• Proven experience designing complex JSON schemas, including objects within arrays and multilevel nesting.
• Strong proficiency in JSON, schema design, and data validation methodologies.
• Demonstrated ability to interpret raw documents and architect robust information models from scratch.
• Deep understanding of required vs. optional fields, data types, field descriptions, and validation rules.
• Hands-on experience with API Gateway management and defining secure API contracts.
• Practical knowledge of JSON Web Token (JWT) standards and secure data handling.
• Exceptional written and verbal communication skills, with attention to detail in documentation and collaboration.

• Background in database design, data modeling, or backend engineering.
• Experience integrating JSON extraction schemas into automated data pipelines.
• Familiarity with regulatory or compliance requirements in data extraction and validation.

Remote position, full-time or part-time contract available.

Hourly rate of $40 - $42.
