The position involves software engineering and integration of third-party AI-enabled language processing services but does not include development or training of proprietary machine learning models. Duties 30% of the time related to Semantic Architecture & Linguistic System Design to design and maintain hierarchical linguistic taxonomies and structured classification frameworks for skills, job titles, industries, credentials, and experience levels used for semantic candidate-job alignment. Apply linguistic principles, including syntactic structure analysis, semantic interpretation, lexical normalization, and ambiguity resolution, to convert unstructured resume and job description text into standardized structured data representations. Develop controlled vocabularies, synonym mapping logic, and disambiguation rules to address variant phrasing and domain-specific terminology. Implement semantic mapping processes aligning natural language inputs with structured database schemas used for classification, ranking, and retrieval. Maintain metadata schemas to ensure consistent semantic relationships across systems. 35% of the time related to Application Development & Platform Engineering to design, develop, and maintain custom WordPress application features, plugins, and application features using PHP, JavaScript, HTML, and CSS.

Maintain retrieval systems, including structured and hybrid search implementations, that rely on linguistically structured taxonomies and normalized datasets. Develop structured prompt configurations and evaluation processes to improve semantic extraction consistency and matching transparency. Implement API and webhook integrations between WordPress, ATS/CRM, and third-party platforms to automate structured candidate and job data synchronization. Generate match explanation outputs based on classification relationships and defined semantic logic. 10% of the time related to Data Engineering & System Integrity to develop and maintain candidate and job data pipelines supporting structured semantic workflows. Implement validation rules, deduplication logic, and data consistency controls aligned with classification frameworks. Monitor database performance, storage systems, and hosting environments to ensure reliability of language-driven retrieval systems. Minimum Requirements Bachelor’s degree (or equivalent) in Linguistics or a related field such as Computational Linguistics, Applied Linguistics, or Language Science. Degree must include at least twelve (12) semester credit hours in semantics, syntax, morphology, linguistic analysis, or language structure. Hunter International is an Equal Opportunity Employer.
