Role Description

We're looking for a Senior Supply & Biz Ops Manager who can hold two things at once: keeping our supply chain running with precision and acting as a strategic operating layer for the business. You'll own the infrastructure that moves hardware from factory to field — and you'll also be an internal strategic operator, a cross-functional connector, and a product partner helping bridge what's happening in the field with what we're building.

You'll work directly with our Head of Operations and be embedded across engineering, product, and customer success. This is a key role at a company with strong product-market fit that is now scaling.

What You'll Own

Supply Chain & Vendor Management

Own end-to-end supply chain operations: production order planning, purchase orders, and BOM management in our inventory management system
Manage and grow relationships with international and domestic suppliers — proactively managing lead times, navigating cross-cultural communication, and escalating risk early
Coordinate with R&D and engineering to keep production timelines aligned with demand signals
Identify and qualify backup suppliers; reduce single-source dependencies over time

Freight, Logistics & Warehouse

Manage international freight from origin to US ports and onward — coordinating customs brokers, ensuring timely paperwork, and balancing cost vs. speed across LTL and express freight
Oversee domestic shipments to clients and installation sites
Coordinate with our warehouse partner on inbound receiving, outbound fulfillment, and inventory accuracy
Support the field installation team with equipment logistics as needed

Financial Operations & COGS

Own COGS tracking, analysis, and monthly reporting — a core input to board-level financials
Partner with the Head of Operations on unit economics: landed cost modeling, margin analysis, and cost reduction initiatives
Manage vendor invoicing and purchase reconciliation in coordination with our finance function
Build and maintain financial models that give leadership clear visibility into supply chain cost structure

Hardware Product Bridge

Serve as the operational connector between our supplier network, the field, and our product team
Translate field feedback and installation learnings into structured inputs: component issues, lead time constraints, quality patterns
Support new product introduction by coordinating logistics, supplier readiness, and component availability for new hardware launches
Participate in design-for-manufacturability conversations — bringing supply chain and cost perspective into early product decisions

Cross-Functional Operations & Systems

Build and maintain SOPs that scale — creating process where there is ambiguity, and improving process where there is friction
Own and evolve our inventory management instance: workflows, automation, reporting
Lead special projects as assigned by the Head of Operations

What we're looking for

3–6 years of operations, supply chain, or biz ops experience — at a hardware startup or physical product company
Hands-on supply chain management: procurement, vendor management, international freight, and customs
Financial fluency: comfortable building cost models, reading P&L implications, and owning COGS reporting
Experience with an inventory management system
Strong cross-cultural communication skills; proven track record working with international suppliers
Comfortable building systems and processes from scratch in a fast-moving, ambiguous environment
High ownership mentality — you notice what needs to be done and do it without being asked
Bay Area-based; ability to work in-person in Santa Rosa preferred
AI experience or a clear, demonstrated willingness to learn — we are an AI-first ops team

Bonus Points

Familiarity with agricultural technology, irrigation, or outdoor/field-deployed hardware
Experience in mechanical or electrical engineering
Fluency in Mandarin Chinese

How to Apply

If you're interested, please send your resume to careers@lumo.ag and an answer to the question: "Tell us about a process or system you built from scratch at a previous company — something that didn't exist before you. What problem did it solve, and how do you know it worked?"
