JOB SUMMARY
The Development Engineer III serves as an advanced individual contributor responsible for leading complex process development and scale-up activities for APIs and intermediates. This role independently drives technical solutions from laboratory through pilot and early commercial manufacturing, applying strong engineering judgment and cross-functional collaboration. This role level demonstrates deep technical capability, ownership of process strategy, and consistent contribution to commercial readiness and continuous improvement initiatives.
DUTIES AND RESPONSIBILITIES
- Lead design and execution of laboratory and pilot-scale experiments for reactions, extractions, distillations, crystallizations, filtrations, and drying operations.
- Develop and reconcile scalable mass and energy balances through commercial projection; validate assumptions with plant data.
- Identify and implement process optimization strategies to improve yield, safety, robustness, and cycle time.
- Serve as technical lead for assigned projects and provide clear process recommendations to stakeholders.
- Own preparation and technical review of batch records, process descriptions, and first-scale batch documentation.
- Lead plant trials, demonstration campaigns, and first commercial batches; confirm CPPs, CQAs, and operating ranges.
- Troubleshoot scale-dependent issues and implement corrective actions during manufacturing campaigns.
- Partner with Manufacturing, Quality, EHS, and Supply Chain to ensure safe, compliant, and efficient scale-up.
- Evaluate reactive and hazardous materials, recommend mitigation strategies, and support hazard assessments (e.g., dust hazard data, reaction calorimetry).
- Collaborate on solvent selection, cleaning strategies, and waste stream optimization.
- Support environmental permitting considerations and ensure adherence to GMP and company safety standards.
- Apply Quality by Design (QbD) principles, including design of experiments (DoE), definition of CPPs, and control strategy development.
- Analyze process data to support investigations, deviations, and continuous improvement initiatives.
- Prepare technical reports, scale-up summaries, and client-facing documentation as required.
- May perform other duties as assigned.
