About the job

1. Sample Evaluation & Validation Testing

Catch fit, function and cosmetic issues at the sample stage, while they’re still cheap to fix.Evaluate vendor samples at each gate (T1 / T2 / T3 and beyond) for fit, function and cosmetic quality against specification, with written findings

• Run bench functional testing (priming, dosage, actuation force, restitution, seal and leakage) and report results
• Coordinate formula–packaging compatibility testing with labs and formulation, and track results to completion
• Issue clear, specific correction lists to suppliers after each sample round

2. Quality GatesMake sure what reaches the line is what was approved

Conduct PPS / decorated PPS reviews, first article inspections and line trial observations, with a written report for each

• Review finished-good assembly at the contract manufacturer and report findings ahead of approval
• Investigate component failures, identify root cause and recommend corrective action

3. Specifications & DrawingsGive suppliers and contract manufacturers one unambiguous source of truth

Review technical drawings, dielines and tolerances against structural specification

• Write component specifications and standards for primary, secondary and tertiary packaging

4. Assembly & Fill InstructionsMake sure every contract manufacturer quotes and builds from the same inputs

Write per-SKU assembly and fill instructions for contract manufacturers in Nécessaire’s standard format (fill height, orientation, viscosity range, lot code placement, pack-out)

• Update instructions as launches progress, so CM quotes stay built on the same, unambiguous inputs

5. Platform & Value Engineering ProgramsBring two new pump platforms to launch and find savings without compromising function

Lead the technical workstream on the airless and atmospheric pump programs: sample evaluation, validation tracking and test documentation

• Test and analyze designated value-engineering projects (material, structure and component changes) and report recommendations
• Work directly with suppliers on sample corrections and tooling adjustments, coordinated with Nécessaire

Required Qualifications

• 3-5+ years packaging engineering experience in beauty, personal care, fragrance or CPG
• Hands-on experience with primary packaging: injection- and blow-molded components, closures, tubes, pumps
• Working knowledge of secondary packaging: folding cartons, rigid boxes, sets and kits
• Able to read and mark up technical drawings; solid understanding of dimensional tolerancing
• Experience running functional and compatibility testing, and documenting results clearly
• Line trial and contract manufacturer experience
• Experience working directly with overseas suppliers (Asia and Europe), including across time zones
• Self-directed; able to manage multiple concurrent workstreams and deliver to agreed milestones
• Able to contract as an independent professional, individually or through a business entity, with their own insurance and tax responsibilities

Preferred Experience

• Airless and atmospheric pump systems — sampling, validation and supplier qualification
• CAD proficiency (SolidWorks or equivalent)
• Transit testing (ISTA) and e-commerce packaging performance
• Decoration processes: hot stamp, screen print, metallization, spray
• Bio-based and recycled resins; sustainability requirements from major retailers
• Limited edition and collaboration launches on compressed timelines
