Wearable and At-Home protein monitoring with silicon photonic chips

About the role

SiPhox fulfillment is the backbone of our customer experience. You’ll own day-to-day kit assembly, inventory, and shipping while building the systems that let us scale with speed and precision, keeping our customers 100% satisfied.

What we’re looking for

A meticulous, high-drive operator who treats inventory accuracy, yield, and on-time shipments as non-negotiables, and is comfortable enforcing standards. Type-A, control-oriented, neurotic attention to detail.

Responsibilities

Inventory, Forecasting & Yield

• Run strict inventory control for all SKUs (kits, components, packaging).
  • Cycle counts, lot/batch/expiry tracking, and reconciliation.
  • Maintain >98% inventory accuracy.
• Build demand and supply forecasts (12–24 week horizon).
  • Translate forecasts into purchase plans and safety stock levels.
• Own yield, scrap, and rework.
  • Track on-time, in-full performance and keep aging orders near zero.

Supplier & Cost Management

• Source, vet, and qualify high-quality suppliers for components, packaging, and logistics.
• Negotiate pricing, MOQs, and terms; prevent single-points-of-failure with dual sourcing.
• Manage the budget for COGS and OPEX; drive cost per kit down without sacrificing quality.

Fulfillment, Logistics & SLA

• Enforce our SLA: every order ships within 1 business day.
• Coordinate inbound & outbound freight, 3PLs, and parcel carriers; resolve exceptions in real time.

Quality Assurance & Compliance

• Stand up a robust QA system across incoming, in-process, and final inspections.
• Define sampling plans, acceptance criteria, and stop-ship triggers.
• Champion Good Documentation Practices; align workflows with ISO 13485-style rigor.

SOPs, Training & Safety

• Write crystal-clear SOPs for kit assembly, fulfillment, inventory, and QC checks.
• Build role-based training, workstation standards, and audit checklists.
• Maintain a tidy, safe floor, calibrated equipment, and compliant handling.

Software & Automation

• Partner with software engineering to build & optimize internal tools for fulfillment, assembly, inventory, and forecasting.
  • Define requirements, write user stories, and own user acceptance testing.
  • Work with & automate integrated barcode scanning, camera streaming for QA, lot/expiry capture, and real-time dashboards.
• Evaluate/implement WMS; ensure clean and reliable data.

Success metrics you’ll own

• SLA hit rate: ≥99% of orders shipped within 1 business day
• Inventory accuracy: ≥98% (cycle-count verified)
• First-pass yield (FPY): ≥99% for standard kits
• Forecast error (MAPE): improving quarter-over-quarter
• COGS per kit: tracked and trending down with quality intact

Basic qualifications

• 3+ years in operations/supply chain/fulfillment.
• Proven ownership of inventory systems and aggressive ship-speed SLAs.
• Strong analytical toolkit: spreadsheets, dashboards, and KPI-driven decision-making.
• Supplier sourcing and budget management experience.
• Exceptional attention to detail and process discipline; writes and enforces SOPs.
• Comfortable working in a fast-moving, hands-on environment.

Nice to have

• Experience with WMS implementation, barcode systems, and label/scan/print workflows.
• Strong scripting (Python/React) ability for lightweight automation and analytics.
• 3PL management and cold-chain shipping experience.

How we work

• Ownership, precision, and speed. You’ll have end-to-end control of fulfillment so kits ship on time and quality never slips.
• In-person, hands-on. Onsite in Burlington, MA to walk the floor, fix bottlenecks fast, and collaborate tightly with engineering and ops.

Benefits

• Competitive salary + stock options
• Medical, dental, and vision coverage
• Membership to Lifetime Gym
• 401(k)
• Weekly company-wide lunches
