Materials & Technical Compliance Engineer

About the company

Founded in 2017, re Purpose Global is the leading Packaging Sustainability & Compliance platform for consumer companies. We enable brands to measure their plastic footprint, recover plastic waste from nature through a global partner network, and streamline compliance across 45+ packaging regulations — all from one platform.

re Purpose has recovered over 100 million pounds of plastic waste, supported 2,300+ waste workers, and maintains 12 active impact projects worldwide. Our platform helps brands achieve compliance outcomes through advanced data management and regulatory expertise.

re Purpose Global helps brands meet their Extended Producer Responsibility (EPR) obligations across a fast-growing set of U.S. and Canadian jurisdictions, with expansion into global circular economy frameworks. Every defensible compliance filing relies on exact technical truth: precisely defining what a product is made of, then mapping those attributes directly into statutory rules. Dissecting complex BOMs, raw material specs, and material attributes across thousands of SKUs is the technical core of what we do.

As our Materials & Technical Compliance Engineer, you'll own that core. This is a hands‑on material analysis role at heart: you'll break a product or packaging assembly down into its constituent materials, layers, and coatings; determine composition and weights — building the equivalent of a Full Material Disclosure (FMD) when suppliers can't provide one; and translate that into precise classification decisions grounded in the statutory text of each jurisdiction.

You'll also help customers move their materials forward — modeling material switches, source‑reduction options, and lower‑fee alternatives grounded in design‑for‑circularity principles — and shaping the rules engine behind our proprietary compliance and material optimization platform. It's the meeting point of materials science, regulatory rigor, and applied analysis — engineered to flex across new physical material categories and regulatory regimes as they emerge.

You'll be the person who resolves the hardest classification and material questions no one else can, and who owns the classification logic that turns material facts into correct reports. You'll work alongside a product and engineering team who build the tools around this logic, serving as the technical authority who informs and grounds that work. Day‑to‑day, you'll own the technical calls that turn material facts into accurate, defensible reporting and audit‑defensible filings.

• Analyze material composition & BOM structures. Break components down into their materials, layers, formulations, and coatings; determine resin, substrate, or compound types, percentages, and weights; and build defensible assumed compositions and material proxies when supplier specifications are incomplete or missing.
• Make classification determinations grounded in regulation. Translate material composition into correct reporting classifications for each jurisdiction, reading and applying the relevant statutory and program definitions rather than generalizing across programs.
• Model material recommendations for customers. Run material‑switch, source‑reduction, and fee‑scenario analyses — identifying more recyclable, lower‑fee, or reduced‑material alternatives — and translate the tradeoffs (cost, physical performance, and eco‑modulation rates) into guidance customers can act on.
• Own the classification logic. Author and maintain the classification configuration (the routing rules that map material attributes to reporting categories) across jurisdictions, and modernize it as regulation and materials evolve.
• Run rigorous quality control. Own schema conformance and a multi‑pass QC process — checking for material and threshold errors, gaps, overlaps, and misroutes — and provide final technical sign‑off on client deliverables.
• Resolve the hardest technical questions. Serve as the deepest tier of the technical queue for escalated composition, classification, exemption, and mapping questions.
• Shape our automated recommendation engine. Define the material…
