About this role
About Periodic LabsWe’re an AI and physical sciences company building state-of-the-art models to accelerate breakthroughs across materials, energy, and beyond. Backed by world-class investors and growing rapidly, we operate at the pace the frontier requires. Our team brings deep expertise, genuine ownership, and an insatiable drive to push the boundaries of what’s scientifically possible.
About the RoleWe are seeking a highly analytical, systems-oriented Procurement & Finance Operations Manager to own procurement, inventory strategy, operational finance, and purchasing systems across our laboratory and R&D environments.
This role sits at the intersection of scientific operations and finance. You will help build the operational infrastructure required to scale experimentation volume dramatically while maintaining financial discipline, inventory reliability, and operational efficiency.
You will own the full lifecycle of lab procurement and financial operations — from vendor management and inventory forecasting to purchase order workflows, budgeting, spend analytics, and experiment cost modeling. A key responsibility of this role will be developing systems and processes that enable the company to understand and optimize the true cost of experimentation across materials, compute, capital equipment, and operational overhead.
This is not a traditional procurement role. We are looking for someone who can think deeply about operational systems, financial rigor, automation opportunities, and scalable workflows in a rapidly evolving technical environment.
What You’ll DoOwn purchasing operations across lab consumables, specialty materials, gases, chemicals, equipment, and operational supplies
Develop inventory forecasting systems and consumption tracking processes to prevent stockouts and support rapidly scaling experimental throughput
Build systems to analyze and track the true cost of scientific experiments across materials, compute, equipment utilization, and operational overhead
Own purchase order generation, invoice reconciliation, and three-way matching workflows across procurement and accounting processes
Track operational and capital expenditures against budgets and support forecasting, reporting, and cost optimization initiatives
Design and implement scalable procurement, inventory, and operational finance systems as the organization grows
Improve workflows through automation, tooling, inventory tracking systems, dashboards, and process optimization initiatives
Partner closely with scientists, engineers, lab operations, finance, and leadership teams to support evolving experimental needs
Manage supplier and vendor relationships, including pricing negotiations, lead times, and purchasing agreements
Identify operational bottlenecks and help build the infrastructure and processes required to scale high-throughput R&D environments
Especially Strong Candidates May Also HaveExperience in advanced materials, hardware, robotics, biotech, semiconductor, or scientific lab environments
Experience building procurement or inventory systems from scratch
Experience implementing inventory tracking systems (QR/barcode workflows, inventory software, etc.)
Experience with operational finance, manufacturing finance, or COGS analysis
Experience supporting high-throughput R&D or experimental environments
Familiarity with automation workflows, reporting systems, or operational tooling
Basic financial modeling and analytics skills
Qualifications5+ years of experience in procurement, operational finance, lab operations, supply chain, or related operational roles
Experience supporting technical, scientific, manufacturing, hardware, or R&D environments
Strong understanding of budgeting, forecasting, spend tracking, and operational analytics
Experience owning procurement workflows, purchasing operations, and vendor management
Experience with PO, accounting, and spend management systems (e.g., Ramp, QuickBooks, NetSuite, SAP, Coupa, Quartzy, etc.)
Strong systems-thinking mindset with demonstrated process improvement experience
Comfortable operating in ambiguous, fast-changing startup environments
Highly organized with exceptional attention to detail
Strong cross-functional communication skills and ability to work closely with technical teams
