Material Flow Supervisor

Slip Robotics is a B2B Robotics-as-a-Service company deploying autonomous loading and unloading robots — SlipBots and SlipLifts — at warehouse and fulfillment sites across North America. Our customers are some of the largest shippers and 3PLs in the industry, and we're scaling fast. We build the robots, we deploy them, and we keep them running.

We are hiring a Material Flow Supervisor to own how parts move inside our four walls — from the moment a truck backs into receiving to the moment a finished robot ships. Our assembly line only builds as fast as it is fed, and today feeding it depends too much on people knowing where things are. You will replace that with a system: defined storage locations, kits staged ahead of the build, line-side replenishment that triggers before a station runs dry, and inventory records the business can actually trust.

This is a working supervisor role on the floor. You will lead a small team of material handlers and run the flow yourself when volume demands it. Supply Chain owns what we buy and when suppliers deliver it; you own everything that happens to a part after it hits our dock.

Responsibilities:

Keep the Line Fed

• Own line-side material availability — no build stops for a part that is sitting in the building
• Run warehouse operations and provide recommendations/feedback on material flow storage and delivery solutions
• Establish min/max levels, replenishment triggers, and point-of-use storage for high-runner parts
• Set the daily material cadence — pick schedules, delivery routes to stations, and handoffs across shifts
• Escalate shortages to Production and Supply Chain with the part, the quantity, and the build it will stop

Own Inventory Accuracy

• Own inventory accuracy for raw material, WIP, and finished goods, with a cycle count program and a stated accuracy target
• Keep ERP transactions clean and timely — receipts, put-away, issues to work orders, moves, and finished goods completions
• Investigate and resolve variances to root cause rather than adjusting them away
• Own the physical stockroom: defined and labeled locations, controlled access, and a layout that matches how the line consumes parts
• Manage excess, obsolete, and non-conforming material segregation with Quality and Supply Chain

Run Receiving, Shipping and Finished Goods

• Own receiving and put-away: verify against the PO, route material to incoming inspection when required, and put it away same day
• Coordinate outbound shipments of finished robots and service parts, including carrier scheduling, load planning, and documentation
• Own dock scheduling and yard coordination so inbound and outbound traffic does not collide
• Maintain accurate shipping records and support customs and cross-border paperwork with Logistics

• 3+ years in material handling, warehouse, stockroom, or production materials, including 1+ years leading or supervising a team
• Hands-on experience with kitting, line-side replenishment, and staging to a production schedule
• Demonstrated ownership of inventory accuracy and a cycle count program
• Working knowledge of an ERP or WMS for receiving, issuing, and inventory transactions (NetSuite or similar)
• Comfortable reading bills of material, pick lists, and packing slips, and matching parts to drawings
• Forklift certified or able to certify, with a clean record operating powered industrial trucks
• Safety-first mindset and a track record of enforcing it without being asked
• Organized and direct — you surface a shortage the moment you see it rather than hoping it resolves
• Physical capability to work on a production floor: lifting up to 50 lbs, extended standing and walking, and occasional after-hours coverage during ramps
• Startup or fast-paced environment experience; you are comfortable building the process while running it
• Eligible to work in the US

Nice to Have:

• Experience in robotics, autonomous vehicles, industrial automation, or another low-volume, high-complexity build environment
• Experience standing up a stockroom, kitting program, or point-of-use replenishment system from scratch
• Lean training and real experience with 5S, kanban, or water spider material routes
• Familiarity with barcode scanning, labeling, and serialized or lot-traceable parts
• Exposure to import/export or cross-border shipping documentation
• Associate or bachelor’s degree in Supply Chain, Logistics, Operations, or a related field
• Bilingual English/Spanish

• Competitive salary and equity in an early-stage robotics company
• Comprehensive benefits including health, dental, and vision
• Permissive time off policy
