Company

hirify.global builds evidence-backed materials datasets extracted from patents and scientific literature and connects them to ontology, extraction, indexing, and search products.

What you will do

• Run the engineering-polymer curation program, including annotation guidelines, calibration, delivery schedules, acceptance criteria, vendor relationships, and reporting.
• Design and execute sampling-based quality control using gold-standard adjudication, inter-annotator agreement, precision, coverage, and independent review of difficult cases.
• Evaluate AI/ML pre-annotation and extraction outputs against curated gold standards and improve guidelines and dictionary rules through error analysis.
• Manage evidence, composition, and normalization-dictionary data contracts and coordinate ontology-gap resolution.
• Translate curated material relationships into indexing and multi-hop search capabilities while maintaining query benchmarks.
• Apply delivery and quality-control practices to additional materials extraction, indexing, and search projects.

Requirements

• Master’s degree in polymer science, chemistry, materials science, or chemical engineering, or a bachelor’s degree with equivalent industry experience.
• Strong command of polymer structures and representations, including repeat structural units, Markush structures, polymer architectures, formulations, compositions, and property-to-sample binding.
• Hands-on formulation, synthesis, or characterization experience, or equivalent scientific judgment demonstrated through relevant patent examples.
• Experience managing quality through structured processes such as GLP/ISO systems, audit readiness, review workflows, or sampling-based data QC.
• Experience managing projects, teams, or external partners against defined deliverables, schedules, and acceptance criteria.

Nice to have

• Applied AI/ML literacy, including extraction-output evaluation, error analysis, precision/recall, or AI-assisted annotation workflows.
• Experience managing outsourced or distributed annotation or curation teams.
• Knowledge-graph, ontology, entity-resolution, information-retrieval, or search-relevance evaluation experience.
• Scripting ability in Python or a similar language for validation, sampling, and QC automation.
• Cheminformatics experience with structure representations, SMILES/InChI, or structure normalization.

Culture & Benefits

• Hands-on scientific role with responsibility for final scientific judgments on curated polymer data.
• Training provided in curation operations, data contracts, hirify.global Materials Ontology, patent data conventions, knowledge graphs, and search evaluation.
• Collaboration with internal and external data curators, ontology, extraction, search, product, and engineering teams.
• Full-time, on-site work in Singapore.
