Sr. Supply Chain Planner

Onsite

Arcaea is building a new ingredient toolset for the beauty and personal care industry – one rooted in biotechnology with the aim of delivering radical performance and unparalleled sustainability that will also present new opportunities for storytelling.

We're looking for a Senior Supply Chain Planner to own end-to-end inventory strategy across Arcaea's two consumer brands. This role suits someone who can operate as a builder and a partner. Reporting to the SVP of Supply Chain and Operations, you’ll build processes from the ground up, including our Sales & Operations Planning process and NetSuite as a true system of record, alongside a small team equally focused on streamlining, standardizing, and building systems that scale. As the connective tissue across teams, you'll translate forecasts and production plans into a planning function built on discipline and data.

 

WHAT YOU’LL DO

S&OP & Demand Planning

  • Design and own Arcaea's monthly S&OP process, aligning demand forecasts, supply plans, and inventory targets across both brands
  • Facilitate the monthly S&OP meeting with commercial, finance, and operations leadership, surfacing deviations, risks, and trade-off decisions before they become problems
  • Own demand analysis and convert it into production plans that meet forecast demand

Systems & Data (NetSuite, Celigo, Netsuite Connector, Shopify)

  • Serve as the team's NetSuite subject matter expert, owning item master, BOM, and planning for raw materials, components, and finished goods
  • Own end-to-end item setup, including UPC generation and BOM creation, ensuring 100% system data integrity at all times
  • Maintain accurate lead times, batch sizes, safety stock targets, and reorder points
  • Ensure inventory flows between NetSuite and Shopify are optimized; own the escalation process with consulting team to troubleshoot and resolve issues
  • Own SKU and UPC checks in the PageProof artwork routing process 
  • Provide Shopify reporting as needed 

Inventory & Financial Stewardship

  • Own the inventory budget across both brands, forecasting inventory investment and tracking actuals against targets
  • Partner with Finance on a recurring cadence to review and approve inventory write-offs and reserves, ensuring accurate, audit-ready books
  • Report on inventory health, aging, excess & obsolete stock, and out-of-stock risk to Operations and Finance leadership
  • Work closely with Logistics Manager on cycle counting and year physical inventory maintaining a 99.9% inventory accuracy KPI
  • Own the yearly obsolete inventory destruction process, determining timing and P&L impact with the broader team
  • Build cost models for new product launches to ensure margin targets are met, and maintain margin records across all products 
  • Investigate margin issues in the monthly P&L review and build the narrative behind any challenges 

Supplier & Production Management

  • Negotiate with new and existing suppliers to establish competitive contracts and agreements
  • Attend weekly supplier meetings 
  • Own the monthly buy cycle, including sign-off on all planning-related spend
  • Coordinate detailed production schedules with third-party contract manufacturers, providing hands-on support through pilot runs, scale-ups, and material purchasing to keep production on schedule
  • Align warehouse dates with testing protocols in partnership with packaging and quality teams 

Cross-Functional Partnership

  • Act as the connective tissue between brand teams, operations, finance, and manufacturing partners
  • Represent supply chain planning in cross-brand launch planning and post-launch retrospectives
  • Take on ad hoc reporting as needed
  • Support in-office logistics tasks (shipping, receiving) as part of a lean, hands-on team 

 

WHAT WE SEEK

  • 7+ years of experience in a supply chain planning role, ideally supporting multiple brands or business units
  • Hands-on NetSuite expertise across planning, inventory, and purchasing modules, with comfort owning configuration, not just using it
  • Experience designing or running a formal S&OP process
  • Strong financial acumen with experience partnering with Finance on budgets, write-offs, and inventory accounting
  • Excellent Excel or Google Sheets skills
  • Comfortable building processes and systems from the ground up, and equally comfortable doing it in close partnership with Finance, Logistics, and brand teams
  • Strong communication skills, with experience presenting to and influencing senior stakeholders
  • Excellent organizational skills, with the discipline to manage multiple brands and projects simultaneously and keep accurate records
  • APICS, CPIM, CPM, or CPSM certification a plus
  • Startup or high growth consumer goods experience preferred

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 07/31/2029

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
