Manufacturing Quality Engineer

Manufacturing Quality Engineer

The Manufacturing Quality Engineer is responsible for establishing, implementing and continuously improving quality systems and processes to ensure that LuxQuanta's quantum hardware meets the highest standards of reliability, precision and regulatory compliance throughout the manufacturing lifecycle.

This role combines deep technical expertise with structured problem-solving to enable scalable, repeatable and high-yield manufacturing in a cutting-edge deep-tech environment.

Tasks & Responsibilities

1. QUALITY SYSTEMS DEVELOPMENT

• Systems & Standards: Establish, implement and maintain quality management systems aligned with ISO 9001, AS9100 or equivalent standards tailored to quantum hardware manufacturing.
• Policy Definition: Define quality policies, procedures and work instructions applicable to precision manufacturing processes.
• Certification Readiness: Support the company's progression towards relevant industry certifications as production scales.
• Scalable Systems: Ensure quality systems evolve in line with production volume growth, from low-volume prototyping to scaled manufacturing.

2. PROCESS CONTROL & YIELD OPTIMIZATION

• SPC & Metrics: Develop and monitor Statistical Process Control (SPC) systems and yield metrics to ensure repeatability across precision manufacturing processes (cryogenic systems, photonics, superconducting circuits, vacuum technology).
• Variation Control: Identify process variation, define control limits and implement corrective actions to maintain process capability.
• DOE Leadership: Lead Design of Experiments (DOE) initiatives to optimize critical process parameters.
• Data Analysis: Analyze production data to identify trends, predict yield issues and proactively address process drift.
• KPI Reporting: Define and track key quality and yield KPIs, reporting regularly to production and engineering leadership.

3. SUPPLIER QUALITY MANAGEMENT

• Supplier Audits: Qualify and audit suppliers of critical components, including semiconductors, superconducting materials, optics and cryogenic systems.
• Traceability: Define incoming inspection criteria and ensure full traceability of critical components throughout the supply chain.
• Non-Conformance Resolution: Manage supplier non-conformances, driving corrective actions and tracking resolution to closure.
• Procurement Collaboration: Work with procurement to ensure quality requirements are embedded in supplier contracts and specifications.

4. FAILURE ANALYSIS & ROOT CAUSE INVESTIGATION

• Investigation Leadership: Lead and document failure analysis investigations, coordinating with R&D and engineering teams as needed.
• CAPA: Define and implement effective corrective and preventive actions (CAPA), verifying their effectiveness over time.
• Root Cause Analysis: Conduct root cause analysis using failure analysis tools and techniques (SEM, X-ray, microscopy) in collaboration with technical teams.

5. RELIABILITY & QUALIFICATION TESTING

• Test Definition: Define and execute reliability qualification tests.
• Acceptance Criteria: Establish acceptance criteria and test protocols for new products and process changes.
• Data-Driven Recommendations: Analyze reliability test data and provide recommendations to improve product robustness.
• NPI Support: Support new product introduction (NPI) processes from a quality and reliability perspective.

6. CROSS-FUNCTIONAL COLLABORATION

• Manufacturable Design: Work closely with R&D and Operations to transition designs into manufacturable, high-yield processes.
• Milestone Alignment: Collaborate with Operations to align quality milestones with project timelines and production planning.
• Sales Support: Support Sales with quality documentation and technical responses for client audits or tenders.

7. DOCUMENTATION, COMPLIANCE & AUDITS

• Documentation Control: Maintain accurate and up-to-date quality documentation, ensuring full traceability and version control.
• Regulatory Compliance: Ensure compliance with applicable regulatory and industry-specific quality requirements.
• Data Integrity: Contribute to the company's data integrity and quality record-keeping practices in line with applicable standards.

It's Important to Us That You Have:

• Problem-Solving Mindset: A structured problem-solving approach combined with strong analytical skills.
• Cross-Functional Communication: Excellent communication skills, able to work effectively with R&D, Operations and external suppliers.
• Agility with Rigor: The ability to balance rigor with agility in a fast-paced scale-up environment.
• Ownership: High attention to detail and a strong sense of ownership over quality outcomes.
• Resilience: Adaptability when navigating the ambiguity inherent to a deep-tech, low-volume-to-scale environment.
• Self-Direction: A proactive, self-driven approach, capable of working autonomously as an individual contributor.

Qualifications & Skills:

• Bachelor's or Master's degree in Electronics or Mechanical Engineering, Materials Science, Electrical Engineering, Physics, Industrial Engineering or a related field.
• Additional certification in Six Sigma (Green Belt or Black Belt), Lean Manufacturing or quality management (ISO 9001 Lead Auditor) is highly valued.
• 3-7 years of experience in manufacturing quality engineering, ideally in semiconductors, photonics, precision hardware, aerospace, or medical devices.
• Demonstrated experience taking products from prototype to volume production in a precision manufacturing environment.
• Experience working in scale-up or high-growth technology environments is a strong plus.
• Track record of leading structured problem-solving investigations (8D, FMEA) to resolution.
• Strong knowledge of ISO 9001 / AS9100 quality management systems.
• Proficiency in Statistical Process Control (SPC), Design of Experiments (DOE) and reliability testing methodologies.
• Familiarity with failure analysis (FA) tools such as SEM, X-ray and microscopy.
• Familiarity with quality management software and electronic documentation systems.
• English and Spanish: full professional working proficiency.

Compensation

• Competitive salary, private health insurance and ticket guardería.
• Lunch at the office for less than 2€!
• Flexible working hours and hybrid work model.
• Short Fridays during the Summer.
• Opportunities for professional development and career growth in a vibrant multicultural work environment in Barcelona.
