SUPPLY & INVENTORY PLANNER

Job Description

ABOUT MARKETLAB

Marketlab is a market-leading healthcare solutions organization specializing in the design, manufacturing, and sourcing of private-label healthcare products. Our mission is to provide healthcare partners timely, practical solutions grounded in deep understanding of their work. Every day, we strive to positively impact the lives of the people who, in turn, support the health and wellness of our communities.

Based in Grand Rapids, Michigan, Marketlab’s success is built on collaboration, accountability, and operational excellence. Strong systems, clear data, and trusted partnerships are foundational to how we operate and scale.

THE OPPORTUNITY

Marketlab is in the midst of an exciting transformation, and we are looking for an analytically driven Supply & Inventory Planner to serve as the architect of our inventory replenishment engine. In this high-impact role, you will take ownership of the quantitative models governing more than 20,000 commercial SKUs and manufacturing components across our national distribution network and internal manufacturing site. You will lead our quarterly ABC/ROP optimization, collaborate with strategic suppliers on capacity planning, orchestrate seamless product lifecycle transitions, and positively impact customer fill rates for Tier 1 healthcare distributors and health systems. Partnering cross-functionally with Data & Analytics, Product Management, and Purchasing, you will modernize planning workflows, optimize NetSuite parameters, and directly influence working capital, service levels, and EBITDA. If you are energized by turning complex datasets into proactive operational stability and want high-visibility ownership in a growing healthcare organization, this is the role for you.

What You’ll Do

• As the architect of inventory planning governance, you’ll take full operational ownership of the ABC classification and Reorder Point (ROP) optimization cycle across 18,000 commercial SKUs and 2,500 manufacturing components. Transform analytical models into ERP replenishment parameters to maximize service levels.
• Bridge Commercial insights and supply chain execution through demand reviews for select strategic product lines. Partner with Product Management to capture market intelligence, sales surges, promotions and contract wins, rapidly translating commercial forecasts into off-cycle ROP updates to ensure supply continuity.
• Proactively analyze supply requirements for strategic, growth-focused product categories and audit production capacity across key supplier partners. Model supplier constraints, minimum order quantities (MOQs), and lead-time volatility to eliminate upstream supply bottlenecks before they disrupt fulfillment.
• Orchestrate critical product transitions by designing and executing run-out and phase-in inventory schedules for New Product Introductions (NPI), product conversions, and SKU phase-outs. Secure day-one commercial product availability while aggressively mitigating Excess & Obsolescence (E&O) write-off risk.
• Empower our Purchasing function by serving as the chief analytical partner to the Buying team. Conduct root-cause investigations on recurring replenishment exceptions, recalibrate broken system parameters, and provide clean replenishment triggers so Buyers can execute orders with maximum speed and certainty.
• Monitor Days Inventory on Hand (DIOH) and order fill rates to deliver actionable, data-backed trade-offs to Supply Chain leadership that efficiently utilize working capital while defending strict delivery SLAs for our Tier 1 distributor and health system partners.
• Mature our planning architecture by maintaining planning Standard Operating Procedures (SOPs) and analytical workflows, supporting the broader organizational roadmap toward automated ERP replenishment.

What You’ll Need

• Bachelor’s degree in Supply Chain Management, Business, or a related field, or equivalent professional experience.
• 3 to 5 years of experience in inventory planning, supply planning, or materials planning, ideally within a high-SKU distribution or hybrid manufacturing and distribution environment.
• Hands-on experience managing planning parameters, item records, and replenishment triggers within NetSuite or a similar tier-one ERP system.
• Advanced proficiency in Google Sheets and/or Microsoft Excel (data modeling, complex formulas, index/match, pivot tables) to manipulate large datasets and execute offline planning models.
• Demonstrated mastery of statistical safety stock calculations, Reorder Point (ROP) mechanics, ABC stratification, and supplier capacity planning.
• Experience in medical products distribution, healthcare supply chains, or light manufacturing (machining, assembly, kitting) is preferred.
• APICS / ASCM certification (CPIM, CSCP) is a plus.

COMPETENCIES

• Analytical Acumen & Modeling: Possesses a natural drive to interrogate large datasets, identify underlying demand patterns, and translate operational variables into mathematically sound inventory parameters.
• Proactive Capacity Problem Solving: Anticipates supplier capacity bottlenecks, component shortages, and product lifecycle transition risks well before stockout thresholds are reached.
• Cross-Functional Facilitation: Translates technical inventory mechanics into clear, practical business decisions when guiding Product Management and Sales on demand and inventory trade-offs.
• Process Discipline & Data Integrity: Takes meticulous ownership of planning models and ERP parameter accuracy, understanding how small data errors cascade into major operational and financial disruptions.
• Working Capital Stewardship: Operates with a balanced mindset that aggressively protects customer service levels and Tier 1 distributor fill rates while vigilantly mitigating inventory holding costs and E&O risk.

• Scholarship reimbursement
• 401k match
• Benefits effective day one of employment
• Paid short term disability leave
• Generous PTO policy that starts on day one
• Paid holidays
• Health and wellness program
