About The Position

Pathways is a fast-growing, venture-backed climate tech company building the data infrastructure that makes sustainable construction possible. The built environment accounts for nearly 40% of global carbon emissions, and most of the construction industry still lacks the tools to reliably measure impact. We're changing that. We're a small team who care deeply about the problems we're solving, move fast, and set ambitious targets. We've raised $10M to date, backed by leading investors like Sorensen, Positive Ventures, and strategic partners from within the industry, and doubled in size last year. The market is moving and we're scaling to meet it. The future of construction doesn't have to choose between sustainability and progress; we're building the tools to prove it. Join us.

Requirements

5-8 years of LCA experience
Deep fluency in EN 15804+A2, ISO 14040/14044, ISO 14025, and the relevant PCRs.
Construction-materials background - concrete, cement, aggregates, or SCMs - is a hard requirement.
Real project management experience: You've run 5+ concurrent technical workstreams against hard deadlines, ideally cut at a top-tier consultancy (Big 4, sustainability/engineering, or LCA specialist firm) or as a freelance practitioner.
Shipped EPDs through verification under EN 15804.
Extreme attention to detail: Precision in inputs, units, and documentation is non-negotiable.
Ability to translate between stakeholders: You move fluidly between standards-speak, engineer-speak, and plant-operator-speak without losing meaning.
High-agency mindset: You're comfortable operating with autonomy, making calls, and owning outcomes in a fast-moving environment.
Comfortable working across time zones.
Based in New York: NYC based or willing to relocate.
Mission-driven: Decarbonizing the built environment is part of why this work matters to you.

Responsibilities

Be the technical authority inside Pathways, setting the standard for defensible LCA across the platform, customers, and verifier relationships.
Own the standards: EN 15804+A2, ISO 14040/14044, ISO 14025, the PCRs. Translate clause-level requirements into modeling decisions, product behavior, and customer-facing guidance.
Keep the methodology current as the standards evolve.
Manage technical relationships: Work directly with concrete producers and their LCA leads. Review their models, sanity-check their inputs, turn plant-specific quirks into clean, defensible LCA structures inside the platform.
Lead verifier interactions: Defend modeling choices, close findings, and turn revisions around fast.
Shape the platform: Partner closely with Product and Engineering. Translate standards into product requirements, review implementations, argue for the right defaults.
Run multiple workstreams in parallel with hard deadlines.
