Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Design and maintain data pipelines to collect and standardize chemical product and supplier information from various sources. Develop automated ETL workflows and classification models to ensure data accuracy for the procurement platform.
Requires 5+ years of experience in data science or engineering with a strong proficiency in Python and experience with messy industrial datasets. Must possess working knowledge of chemical industry data, including CAS numbers and SDS documents.
At Valdera, we empower innovators to turn ideas into reality by transforming how manufacturers source materials. We make it effortless for companies to find the best materials and suppliers for their needs, enabling them to build high-quality products at scale and deliver them to millions of consumers worldwide.
We are a team of ambitious, results-driven individuals with a proven track record of working with Fortune 500 industrial manufacturers, beauty brands, and chemical companies. We are a fast-growing company that hires talented, hardworking people who excel in high-performance environments and want to grow their careers quickly.
Our culture is built for exceptional individuals to take on meaningful challenges, collaborate with the top minds in our industry, and see the direct impact of their work. If you’re looking for a fast-paced environment where your ideas will drive real change, Valdera is the place for you.
Join us, and let’s shape the future of manufacturing together.
We are hiring a Chemical Data Scientist to build and maintain the pipelines that keep Valdera's supplier and chemical product data accurate, current, and structured — the foundation every buyer and supplier relies on across Valdera's procurement platform.Data quality plays a critical role at Valdera. When a buyer launches a request, they expect to be matched with the right suppliers and accurate specs on the first try. Delivering that depends on clean, current data — CAS numbers, specifications, certifications, and regulatory documents pulled from thousands of inconsistent, often messy sources. This requires strong data engineering fundamentals and a working knowledge of chemical industry data. For example, you might take dozens of differently structured chemical supplier catalogs and turn them into one clean, standardized product databaseYou will take ownership of the full data pipeline — from scrapers and ETL workflows to data cleaning, matching, and classification models that connect suppliers to buyer requirements. You're energized by messy, real-world data and confident partnering with Supplier Management and Engineering to close coverage gaps. As a data-obsessed professional, you're dedicated to the accuracy our buyers and suppliers depend on.
\nRole Responsibilities:Design and build pipelines to collect supplier data and chemical product information (specifications, CAS numbers, certifications, SDS/regulatory documents, NAICS classification of manufacturing plants) from supplier sites, distributor catalogs, trade databases, and other public and semi-structured sources
Develop and maintain web scrapers and automated ETL workflows to keep supplier and product data current at scale
Clean, normalize, and reconcile inconsistent supplier data into structured, standardized formats suitable for internal tools and analytics
Apply chemical domain knowledge to validate and enrich data — resolving product names, CAS numbers, synonyms, and specifications across suppliers
Evaluate and improve matching and classification models to map suppliers and products to buyer requirements, and to identify overlapping or equivalent chemical offerings
Partner with Supplier Management and Engineering to define data quality standards, identify gaps in supplier coverage, and prioritize new data sources.
Own pipeline health and data quality, and drive the KPIs that measure overall data coverage
5+ years of experience in a data science, data engineering, or applied data role, ideally with exposure to messy, real-world or industrial datasets.
Working knowledge of chemistry or chemical industry data — comfort with CAS numbers, chemical properties, SDS documents, NAICS classification, and supplier certifications
Strong Python skills, with experience building web scrapers and data pipelines
Experience with data cleaning and normalization at scale, and a good eye for spotting inconsistencies in unstructured data
Familiarity with building or applying matching, deduplication, or classification models (traditional ML or LLM-based approaches)
Hands-on experience using AI tools and LLMs to accelerate data extraction, enrichment, or engineering workflows
Startup mindset with a strong sense of ownership — comfortable working independently in a fast-moving, remote environment with ambiguous, evolving priorities
Salary ranges are determined by multiple factors, including the labor market, market compensation bands, internal parity, and budget considerations. The final offer will be based on the candidate’s individual skills, qualifications, location, and experience relative to the requirements of the role.
