This position also owns the technical evaluation, verification, and continuous improvement of cleaning and sanitation processes for compounding, batching, equipment changeovers, and laboratory operations to ensure effective contamination control and scientifically sound cleaning verification practices. In addition, the Technical Quality Engineer provides technical training, coaching, and quality support to Quality Control and Laboratory personnel and serves as a key quality partner in building standardized, scalable manufacturing systems that support growth, operational reliability, and successful commercialization.

  • Lead and support root cause analysis, CAPA development, and effectiveness verification.
  • Participate in FMEA activities, risk assessments, and process qualifications.
  • Support continuous improvement initiatives focused on yield, consistency, quality performance, and process capability.
Cleaning Validation amp; Sanitation Process Ownership
  • Own the evaluation, verification, and continuous improvement of cleaning and sanitation processes associated with compounding, batching, changeovers, and laboratory operations.
  • Ensure cleaning procedures, techniques, frequencies, and acceptance criteria are appropriate, effective, and scientifically justified.
  • Establish, assess, and verify cleaning effectiveness and verification testing methods (e.g., visual inspection, analytical testing, rinse testing, residue limits).
  • Support cleaning validation activities and risk assessments related to formulation changes, scale‑ups, and new product introductions.
  • Investigate cleaning‑ and sanitation‑related deviations and drive corrective and preventive actions.
  • Support development, maintenance, and training of SOPs and work instructions related to cleaning and sanitation practices.
Quality Liaison amp; Technical Support
  • Act as the technical Quality Assurance liaison between R amp;D, Production, and Quality Control.
  • Ensure proper testing techniques, sampling plans, quality dispositions, and acceptance criteria are clearly defined and consistently applied.
  • Provide real‑time technical support during trials, batching, scale‑ups, and troubleshooting events.
  • Support batch disposition decisions for trials and routine production.
Training amp; Coaching
