At Open Cosmos we are solving the world’s biggest challenges from space, providing businesses, governments and researchers access to more readily available information than ever before. Our COO Teams are the engine that powers Open Cosmos’ operations. This division brings together mission management, supply chain, and quality & product assurance to make sure every mission is delivered smoothly, reliably, and to the highest standards.

Working in the QPA Team, our Quality and Product Assurance (QPA) team is central to ensuring that everything we deliver meets the highest standards of performance, reliability, and safety. The team is dedicated to embedding quality into every stage of our work from design and development through to production, testing, and launch ensuring that our satellites and systems are ready to perform their mission with confidence.

As a Quality Control (QC) Engineer, you’ll be a hands‑on presence providing quality oversight during build, integration, and test activities. You’ll work closely with Engineering, AIT, Supply Chain, and suppliers to ensure only fully compliant hardware and software progress through the production lifecycle.

• Perform incoming, in-process, and final inspections of mechanical, electrical, and electronic hardware in line with ECSS, ISO9001, and internal quality requirements.
• Verify compliance against engineering drawings, specifications, and acceptance criteria.
• Provide quality oversight during AIT activities, including integration, testing, and environmental campaigns.
• Raise, document, and track non‑conformances, deviations, and waivers, supporting root cause analysis and corrective actions.
• Participate in Material Review Boards (MRBs) and support implementation of agreed dispositions.
• Ensure configuration management and full traceability across design, build, test, and delivery phases.
• Review manufacturing, inspection, and test documentation for completeness, accuracy, and compliance.
• Support supplier quality activities, including source inspections, incoming acceptance, and follow‑up on supplier non‑conformances.
• Contribute to formal reviews (PRR, TRR, QR, FRR) by providing inspection status, quality metrics, and evidence of compliance.
• Maintain accurate quality records in ERP/PLM systems and digital QMS tools.
• Identify recurring issues and trends, contributing to continuous improvement initiatives.
• Support internal and external audits with clear, well‑structured quality evidence.

You’ll have a practical, detail‑driven mindset and enjoy working close to the hardware, ensuring quality is applied, verified, and documented at every stage and bring:

• Hands‑on application of Quality Control activities within a regulated engineering or manufacturing environment.
• Working knowledge of ECSS, ISO9001, and relevant space or aerospace quality standards.
• Capability to perform inspections, testing, non‑conformance reporting, and support root cause analysis and corrective actions.
• Ability to read and interpret engineering drawings, specifications, and test procedures.
• Understanding of configuration management, document control, and traceability requirements across the product lifecycle.
• Ability to work effectively with suppliers and cross‑functional internal teams.
• Comfort using ERP/PLM systems and digital QMS tools to maintain accurate quality records.

If successful you’ll work a rotating 24/7 shift pattern, supporting continuous assembly operations and satellite production while helping ensure key manufacturing milestones are delivered and coverage is maintained at all times.
